The aging process is commonly associated with declines in health, cognitive function and
well-being. However, lifestyle factors like diet, alcohol consumption, smoking and physical
activity were repeatedly highlighted as predictors of a healthy aging process. However, recent
research has shown that physical activity is the strongest predictor of health in older adults.
Recent studies have confirmed the strong effect of physical activity on cardiovascular,
metabolic, musculoskeletal and mental health in this age group, while the World Health
Organization and other bodies have published physical activity guidelines. Despite the
overwhelming evidence of the positive effects of physical activity older adults around the
globe tend to be inactive. An effective way to increase the physical activity levels in older
adults is physician consultation, and this should be implemented widely.

Physical activity (PA) appears to be one of the most used buzzwords when it comes to viable
means to improve health and prevent diseases across all age groups (World Health
Organization, 2010). Even though the literature basis concerning PA and health is increasing
steadily, and in order to provide a precise picture about the health related effects and benefits
of PA in especially older adults, as one of the core intentions of this paper it appears to be
necessary to precisely define what this term means. For the purpose of this article and as used
by most researchers PA refers to any bodily movement employing the skeletal muscles that
results in increased energy expenditure compared with the resting rate. Exercise is a
subcategory of PA as it incorporates planned, structured and repetitive movements that are
performed in order to maintain or improve health and fitness (Caspersen, Powell, &
Christenson, 1985; INSERM, 2008). The term sport describes another subset of PA and
means that exercises are performed in a specialized and organized form in order to improve
competitive performance (INSERM, 2008). The latter will not be of relevance for this article
as its main goal is not health or well-being.
In this literature review the focus will be on PA and exercise as means to benefit older
adults in terms of health and longevity.
Benefits of Physical Activity
The benefits of physical activity, including, but not limited to exercise are well documented
in the scientific literature, starting from the seminal work of Morris and colleagues (1953)
who reported positive association between work-related physical activities and lower risk of
cardiovascular disease as well as all-cause mortality (Morris & Heady, 1953; Morris, Heady,
Raffle, Roberts, & Parks, 1953). Recently, Warburton and his research group (2010, 2007,
2006) conducted extensive reviews on health benefits of PA in adults and found that regular
PA is associated with lower risks of all-cause mortality and useful in primary and secondary
prevention of several diseases (Warburton, 2006; Warburton, Katzmarzyk, Rhodes, &
Shephard, 2007; Warburton, Charlesworth, Ivey, Nettlefold, & Bredin, 2010).
According to the review by Warburton et al. (2010), drawing conclusions from 70
research studies, the relative risk of premature death can be reduced by a mean of 31%
comparing the least active with the most active group, while emphasizing that greater benefits
can be achieved with higher volumes and/or intensities of PA. However, also small
increments have a marked effect. Another study by Blair et al. (1995) showed that unfit
adults who implemented PA over a period of five years and therefore became physically fit
had 44% lower relative risk of death compared to individuals who remained unfit, a finding
highlighting elevated mortality benefits for people with initially low PA levels. Additionally,
Myers, Prakash, Froelicher, Partington and Atwood (2002) examined the effects of PA on all-
cause mortality in individuals with already existing chronic disease risk factors and found
strong risk reductions among people who were active and/or more physically fit.
PA plays a major and independent role in the prevention of cardiovascular disease
and was found to reduce the mean relative risk by 33%, which is similar to the effects of PA
in terms of stroke (31%) and hypertension (32%) when comparing high active and low active
individuals (Warburton et al., 2010). Patients in cardiac rehabilitation also benefit from PA
(here in form of exercise) as it improves the disease process and reduces the occurrence of
premature death (Taylor et al., 2004a).
There has been a tremendous amount of research activities regarding the primary as
well as secondary prevention effects of PA concerning breast and colon cancer. Leisure and
work related PA is responsible for mean relative risk reductions of 30% for breast and 20%
for colon cancer (Warburton et al., 2010). Additionally, a study by Lee (2003) indicated that
higher intensities are associated with greater risk reduction, but also lower PA levels have
significant benefits. The decrease of cancer related risk of death and recurrence of breast
cancer through PA was observed in another trial with women diagnosed with the disease
(Holmes, Chen, Feskanich, Kroenke, & Colditz, 2005).
Type 2 diabetes is one of the strongest increasing chronic diseases globally (Wild,
Roglic, Green, Sicree, & King, 2004) and can be demonstrably prevented with healthy
lifestyles, incorporating aerobic and resistance activities, that are significantly more effective
than Metformin treatment a medication commonly given to people at risk (Knowler et al.,
2002). The mean relative risk reduction as shown by Warburton et al. (2010) is 42%
comparing least active with highly active groups. Specifically, each weekly 500kcal increase
in energy expenditure accounts for a 6% risk reduction (Helmrich, Ragland, Leung, &
Paffenbarger Jr, 1991) implying that even small changes in PA behavior are associated with
positive effects, a finding most relevant to at-risk individuals. The health risks related to
obesity, one of the most relevant precursors of type 2 diabetes can be buffered with regular
PA even without significant changes in body weight (He & Baker, 2004). Furthermore,
premature death of patients suffering from type 2 diabetes can be reduced by 39% (any cause)
and 34% (cardiovascular disease) by walking for two hours weekly compared with no
walking activity (Gregg, Gerzoff, Caspersen, Williamson, & Narayan, 2003).
Despite the various effects of PA in terms of somatic health its associations with
mental health outcomes are of emerging interest. A literature review by Penedo and Dahn
(2005) found significant positive relationships between aerobic exercise and improvements in
depression compared to psychotropic treatment. The same review also indicated improved
mood, reductions of symptoms of depression and anxiety through PA. Small effects of PA on
global self-esteem and mental health-related quality of life are further indications of the
importance of an active lifestyle in terms of mental health (Warburton et al., 2007).
In short, PA has a significant impact in the prevention of premature death, the risk
reduction and secondary prevention of several chronic diseases as well as improved mental
status and well-being. Generally, the amount of PA is associated with the quality of the
specific benefits, whereas small increments are also effective (Blair et al., 1995), a fact that
should encourage especially people with low PA and existing risk factors who benefit
markedly from increased activity levels.
The aging process
Aging cannot be explained by a single cause, but as a complex process that depends on the
interaction of intrinsic (genetic), extrinsic (psychosocial and environmental) and stochastic
factors (random damage of vital molecules) (Weinert & Timiras, 2003). Hence, aging can be
experienced differently by different individuals. To accommodate this notion Gremeaux et al.
(2012) highlighted the existence of three theoretical profiles of aging, which are important for
adequately addressing question related to aging. Regular or normal aging refers to gene-
determined declines in physiological functions and processes, whereas cardiorespiratory and
musculoskeletal changes are most important.
In advanced age aerobic fitness decreases faster than the usual rate of 5%-10% per
decade in untrained individuals implying reduced oxygen carrier capacity of the
cardiovascular system that was found to decline more than 20% every ten years for
individuals in their seventies and beyond (Fleg et al., 2005). Geriatric sarcopenia is a
common syndrome among older adults showing a prevalence of 5%13% in people aged 60-
70 years and 11%-50% in individuals aged 80 years and older (Morley, 2008), and is defined
as declining muscle mass and muscle strength or performance (Cruz-Jentoft et al., 2010) as a
result of the aging process itself as well as lifestyle factors or diseases etc. (Doherty, 2003).
Both conditions (among others), even though considered as normal, have strong influences on
quality of life, functional independence and mortality of older adults (Chodzko-Zajko,
Proctor, Singh, Salem, & Skinner, 2009; Gremeaux et al., 2012).
Pathological aging is associated with accelerated aging processes and is mostly related
to diseases. The predicate successful aging, as the gold standard for aging, and accounts for
only about 8.5% of the non-institutionalized European and Israeli population over 50 years
(Hank, 2011) and means the “[…] avoidance of disease and disability, maintenance of high
physical and cognitive function, and sustained engagement in social and productive activities”
(Rowe & Kahn, 1997, p. 439).
Factors influencing health of older adults and the aging process
The aging profile and the health of older adults can be significantly impacted by so called
lifestyle factors as they influence the occurrence of chronic disease and the risk of premature
death. According to World Health Organization modifiable lifestyle factors are tobacco use,
alcohol consumption, diet and PA (plus sedentary behavior) (World Health Organization,
2013). A review by Södergren (2013) on the predictors of healthy aging in men reported that
extended life expectancy accompanied by good health condition and lower probability of
disability is strongest associated with PA and non-smoking behavior, while the impact of
dietary pattern and alcohol consumption is either not yet fully understood or not as relevant
as PA and smoking (Södergren, 2013). Hazard ratios for all-cause mortality in older women
were assessed in a large scale European study. The results clearly indicate the trailblazer role
of PA in the prevention of premature death from any cause as the hazard ratio was 0.63 (CI:
0.55-0.72) and therefore lower than those associated with smoking (0.65; CI: 0.57-0.75), diet
and moderate alcohol consumption (Knoops et al., 2004).
Drawing from the aforementioned studies, PA is an integral, non-pharmaceutical way
to benefit health and expand quality lifespan in older adults (Chodzko-Zajko et al., 2009;
Vogel et al., 2009). In order to provide a more comprehensive picture concerning the
association between health and PA in elderly the following chapter will introduce the current
evidence on that matter.
Physical activity and mortality in older adults
One of first longitudinal cohort studies reporting on the association between physical activity
and mortality that included older adults (age range: 35-74 years) was conducted by the
pioneer of physical activity and longevity research Ralph Paffenbarger and colleagues (1986)
in a sample of 16,936 male Harvard alumni who enrolled between 1916 and 1950. The
research team found a steady decline of death rates associated with increasing energy
expenditure from less than 500 to 3500 kcal per week. Even with adjustment for other risk
factors mortality among active alumni was significantly lower, leading to a mean additional
life span of one to more than two years (Paffenbarger Jr, Hyde, Wing, & Hsieh, 1986). Lee
and Paffenbarger (2000) further collected data on the same group and published the results
from the period between 1977 and 1992. The analysis of the data collected in the study cohort
that consisted then of subjects above 50 years revealed that age adjusted mortality declined
with increasing energy expenditure. The most active elderly added a mean of 1.5 years
(95%CI: 0.85-2.15) to their lifes compared to the least active group.
These results from the Harvard alumni health research were confirmed in several
other studies. A research group from the United States found a significant relationship
between the weekly amount of PA and mortality risk reduction of up to 40% in older adults
with a mean age of 73 years (Fried et al., 1998). Another study examined the relation
between different levels of PA and total life expectancy in older adults which increased
proportionally with higher activity levels. Individuals with moderate or high activity levels
enjoyed an extended lifespan of more than 1.3 and 3.5 years respectively (Franco et al., 2005).
Furthermore, a recent study by Fortes et al. (2013) investigated the role of walking on
longevity in the very old in Italy. After a follow-up of 10 years the researchers concluded that
subjects who walked four times per week for about 15 minutes had halved the risk of
mortality compared to those who did either not walk or walked significantly less frequent.
Physical activity and cardiovascular health in older adults
There is a large amount of evidence confirming the positive effects of PA for cardiovascular
health in older adults. Older study participants in higher activity groups were found to live
1.1 to 3.2 years longer without a cardiovascular disease compared to low activity groups.
Additionally, participants with a cardiovascular disease enjoyed a longer life if they were
moderately to vigorously active (not significant) (Franco et al., 2005). Similarly, a review and
meta-analysis by Taylor et al. (2004) reported that exercise-based cardiac rehabilitation
programs reduced the cardiac and total mortality in older adults about 36% and 20%
respectively. Mortality effects were consistent across a number of coronary heart diseases.
Effects of a 6 months aerobic exercise program on cardiorespiratory health were also found in
adults aged 80 years and older who were more prone of declining functional capacity. After
the intervention period, oxygen consumption and peak oxygen pulse increased significantly
compared to pre-intervention measures (Vaitkevicius et al., 2002). Finally, Mazzeo and
Tanaka (2001) highlighted in an earlier review that older individuals who have been very
inactive benefit greatly from light to moderate PA in terms of cardiovascular health, whereas
active individuals are required to increase exercise intensities for further health gains.
Vogel et al. (2009) and other research groups emphasized the benefits of PA and
exercise in terms of the lipid profile, body composition, type 2 diabetes and hypertension as
metabolic risk factors for cardiovascular diseases (Mazzeo & Tanaka, 2001; Petrella,
Lattanzio, Demeray, Varallo, & Blore, 2005).
The effects of PA adoption in late life on metabolic risk factors were assessed in a 10
years follow-up study (Petrella et al., 2005). Individuals who had an at least 80% program
compliance (3 times 30-45min aerobic exercise per week) enjoyed a significantly better lipid
profile then the inactive group. HDL cholesterol increased by 9% in the active and decreased
18% in the inactive group, whereas LDL cholesterol increased in both groups but to a lesser
extent in active individuals. The same study also found positive effects in terms of body
composition as the mean waist circumference of active subjects increased significantly less
than that of inactive participants (2.12% vs. 10.66%). Moreover, a position paper from the
American College of Sports Medicine noted that the total body fat mass can be reduced by up
to 3.4% via moderate to vigorous resistant activities and up to 4% can be lost with aerobic
exercise training over a trainings period of 2 to 9 months, while highlighting that higher
intensities account for stronger effects (Chodzko-Zajko et al., 2009).
The prevention of diabetes type 2 can also be achieved via aerobic PA or exercise.
Greater leisure time PA (gardening and cycling) was found to be associated with a lower
plasma glucose concentration and lower prevalence of glucose intolerance in non-diabetic
men between the ages 60 and 89 over a five year period (van Dam, Schuit, Feskens, Seidell,
& Kromhout, 2002). Furthermore, higher aerobic exercise intensities seem to improve
glucose utilization to a greater extend compared to low or moderate intensity levels, which
are effective as well, in before inactive elderly women (DiPietro, Dziura, Yeckel, & Neufer,
2006). Subjects already suffering from impaired glucose tolerance experienced reduced risk
of diabetes incidents of up to 65% when they increased leisure time PA from moderate to
vigorous within 4.1 years compared to individuals with lower activity levels (Laaksonen et al.,
Studies on PA and hypertension in older populations are scarce and the evidence is
less consistent compared to the evidence in younger age groups (Vogel et al., 2009).
However, a study by Braith et al. (1994) found a significant decrease in systolic and diastolic
blood pressure in an intervention group after a 6 months walking exercise program compared
to a control group. Another, more recent study discovered only a reduction in resting systolic
blood pressure, but not in diastolic blood pressure after 6 months aerobic exercise training in
men and women with a mean age of 84 years (Vaitkevicius et al., 2002).
Physical activity and musculoskeletal health in older adults
Muscle strength, power or performance are declining in older age leading to a higher
probability of falls, fractures and other health threatening conditions including sarcopenia
(Mazzeo & Tanaka, 2001). Resistance exercise training was found to be an effective way to
counteract these muscle related losses. Such training lead to increases in muscular strength
that were reported to be between 25% and greater than 100% according to a recent review
(Chodzko-Zajko et al., 2009). Muscular power is stronger related to functional performance
in older adults than muscle strength (Foldvari et al., 2000; Reid & Fielding, 2012) and can be
substantially increased with resistance training. Pereira et al. (2012) observed significant
improvements in muscular power, especially for the one repetition maximum in bilateral
bench press (68.1%) after a 12 weeks high speed power training in older women (Pereira et
al., 2012). Furthermore, old and young individuals increased muscle quality, defined as the
muscle performance per unit muscle volume or mass, in similar ranges (Ivey et al., 2000).
The effects of resistance training in terms of muscle endurance in older adults are not well
studied yet, but a few studies found that moderate to high training intensities lead to
improvements between 34% and 200% (Chodzko-Zajko et al., 2009).
The influence of aerobic PA on bone health of older adults is minimal. The American
College of Sports Medicine reviewed research on the effects of aerobic exercise training in
postmenopausal women. The researchers indicated that low intensity activities like walking
can counteract the age-related bone loss in postmenopausal women that was 0.5%-1% per
year in sedentary controls. Higher intensity activities like stairs climbing or jogging lead to
better results in terms of bone health (Bloomfield, Little, Nelson, & Yingling, 2004). These
positive effects are usually only found in the bones directly involved in the particular activity
(Todd & Robinson, 2003). In contrast, strength training shows significantly stronger effects
on bone mineral density (BMD) (Cussler et al., 2003) while another study showed that BMD
increases, even though minimal, is related to increases in muscular strength (Stewart et al.,
2005). Generally, high intensity resistance training can preserve or improve BMD with a
direct relation between muscle and bone adaptations (Chodzko-Zajko et al., 2009).
The effects of physical activity and exercise in terms of bone health are often
attributed to the prevalence of fractures (Bloomfield et al., 2004). A trial by Feskanich, Willet
and Colditz (2002) compared the effects of hormone therapy and physical activity with
regard to the risk of hip fractures in older women. The most active group reduced the hip
fracture risk about 67% (no hormone use) and 71% (hormone use) respectively compared to
the least active group without any hormone treatment.
Physical activity and the immune system in older adults
Organ resistance decreases with advancing age leading to functional declines of the immune
system. That in turn leads to more infectious diseases and a weaker response to vaccination in
older adults (Goodwin, Viboud, & Simonsen, 2006). Apart from surgeries and other immune-
therapeutic procedures that are commonly applied in generally healthy people, lifestyle
factors including PA seem to influence the immune system in older adults.
Adaptations to regular, moderate PA have been associated with improved antioxidant
defence mechanisms. The higher production of free radicals, which are responsible for tissue
damage, through exercise is in itself not positive but these free radicals are partly responsible
for beneficial exercise adaptations (Sachdev & Davies, 2008). Impressive effects of PA have
been found in relation to leukocyte telomere length, the most important marker of biological
aging because it acts as an indicator of morbidity and mortality (Simpson et al., 2012). A
study by Cherkas et al. (2008) reported a 200 nucleotides difference in telomere length in
very active compared to the least active adults with a mean age of 49 years (previous 12
months leisure PA). This difference in length suggests that inactive individuals are
biologically 10 years older than their active temporaries. The dose-response relationship in
older individuals (50-70 years) was investigated by Ludlow et al. (2008). The research team
discovered that long term energy expenditures less than 990 kcal and more than 3541 kcal per
week are significantly associated with shorter telomere length compared to expenditures that
are common in moderate activity, thus suggesting an inverted U relationship between PA
intensity and telomere length. Telomerase as a result of PA was not observed.
Viral infections like influenza and secondary infections are a common health threat
for older adults. Martin, Pence and Woods (2009) reviewed the literature on PA and
respiratory viral infections in the general population and found that acute or chronic moderate
exercise is supportive in its prevention. Exercise also reduces the symptoms of viral
infections and increases viral clearance. On the contrary, vigorous exercise showed negative
results. Additionally, exercise improved the vaccine efficiency in older people, which is
important because the effects of vaccines are significantly weaker in this age group (young
adults: 70-90% vs. older adults: 17-53%) leading to higher risks of infections (Goodwin et al.,
2006). Greater increase in antibody titer to H1N1 and H3N2 after immunization was
observed in moderately exercising adults compared to inactive controls after (Kohut et al.,
2004). Furthermore, the association between age-related chronic inflammation and long-term
physical activity was investigated in a large scale (n=368) randomized controlled trial by
Beavers, Hsu and Ismon (2010). The researchers compared the effects of a 12 months
moderate PA program with an education program. Significant reductions of the biomarker
interleukin-8, which is involved in the recruitment of leucocytes in inflamed areas, were
found in the PA compared to the education group. After adjustment for multiple comparisons
there were no significant effects of PA on any inflammatory markers, a finding that requires
more in-depth investigation.
Physical activity and the cognitive system in older adults
Cognitive decline in its various forms is a normal age-related process leading to many
problems and diseases, like Alzheimer which is responsible for dementia, in older age. So far,
pharmaceutical therapies are only modestly effective, while modifiable lifestyle factors
having a strong impact on the respective prevalence rates (Barnes & Yaffe, 2011). Promising
results concerning the association between PA, exercise and cardiorespiratory fitness, and
brain health in later life were found in a recent review conducted by Errickson, Gildengers
and Butters (2013).
An early study by Spirduso (1975) could already show that older adult athletes
outperform more sedentary peers in many cognitive tasks. Another trial indicated that PA
earlier in life predicts better cognitive performance and less cognitive impairment in older
age. Especially teenage PA lead to less cognitive impairment with an odds ratio of 0.73
(95%CI: 0.58-0.92) (Middleton, Barnes, Lui, & Yaffe, 2010). A meta-analysis concluded that
the effects of aerobic fitness on cognitive domains are general and specific, because many
domains improved after several months while executive functions were significantly more
enhanced than controlled, visuospatial or speed functions (Colcombe & Kramer, 2003). For
example, the increment of PA over 3 to 6 months lead to increased general cognitive
performance of 0.5 SD (Colcombe & Kramer, 2003) while another study on older adults
discovered increased executive functions like planning, scheduling, inhibition and working
memory but no effects in other domains (Kramer et al., 1999).
The evidence reveals a noticeable picture. First, it seems that some brain regions and
networks, especially those supporting executive functions, are more sensitive to PA than
other areas (specifity). This is important because the brain shrinks about 1% to 2% per year
from the age of 55, especially in the prefrontal cortex and hippocampus, the regions
responsible for memory and executive functions (Raz et al., 2005). Second, the brain seems
to be modifiable well into late adulthood (plasticity) which can be detected in improved
cognitive functions (Colcombe & Kramer, 2003; Erickson et al., 2013).
With this, researchers observed more brain volume in active older adults (aerobic
exercise only) than in inactive older adults (Colcombe et al., 2006). Additionally, higher
hippocampal volume of up to 2% was associated with higher fitness levels, while people with
higher baseline PA levels showed reduced loss of hippocampal volume (Erickson et al., 2009;
Erickson et al., 2011). Finally, increased hippocampal volume was reported to significantly
influence memory functions in the elderly (Erickson et al., 2011). The mentioned benefits of
PA also apply to sedentary older adults who become active (Colcombe et al., 2006). In short,
it can be highlighted that regular PA has consistent and robust effects on the brain which
leads to improvements in cognitive performance (Erickson et al., 2013) and reduced
impairment (Laurin, Verreault, Lindsay, MacPherson , & Rockwood, 2001).
Physical activity and mental health in older adults
In 2013 the World Health Assembly published their first action plan for global mental health.
This shows a growing relevance for mental health issues, while urging member states to act
towards a better mental health state of their populations with the best scientific evidence
(World Health Assembly, 2013). Although the meaning of the term mental health is still
under debate, mental disorders like depression, dementia and anxiety, which are highly
prevalent in older adults (Yasamy, Dua, Harper, & Saxena, 2013), indicate disturbances of
mental health. Mental health is an integral part of general health and means to preserve a
healthy mental state are under research (Almeida, Norman, Hankey, Jamrozik, & Flicker,
2006). Smoking and a sedentary lifestyle have been reported to contribute significantly to
negative mental health and also well-being (as a part of mental health) in older adults
(Yasamy et al., 2013).
Almeida and colleagues (2006) (Almeida et al., 2006) investigated the impact of PA
in terms of mental health in 601 men in their 80’s. The research group found that successful
mental health aging was directly associated with vigorous and non-vigorous PA over a period
of five years with reduced risks of 89% and 50% for dementia and depression respectively.
Further, the longitudinal case-control study by Pasco et al. (2011) found physical activity to
be protective against the likelihood of depressive and anxiety disorders (OR = 0.55, 95% CI
0.320.94, p = 0.03) in adults aged 60 and older after a mean follow-up of 4.1 years. Older
people with already existing major depressive symptoms were examined in another study that
tested the antidepressant efficacy of exercise and pharmaceutical treatment (Blumenthal et al.,
1999). After the trial period of 16 weeks the results indicated good antidepressant efficacy of
the exercise, medical treatment and the combination of both, with no differences between the
groups. PA was proposed to also influence general life satisfaction and well-being via
improved self-efficacy, self-esteem and affective/emotional experiences which mediate the
effects of PA (Elavsky et al., 2005). A 6 months walking program with 174 adults with a
mean age of 66.7 years revealed that PA has significant direct effects on self-efficacy, self-
esteem and affect after one year follow-up, whereas after 5 years PA influenced self-esteem
and affect significantly (Elavsky et al., 2005). In conclusion, PA, also in light intensity
influences mental health considerably and is equally effective as antidepressant medication.
Physical activity in the very old
Centenarians live about 50% longer than the world average and this group increases 8%
while the world population increases only 1% annually (Perls, Levenson, Regan, & Puca,
2002). Therefore, this age cohort seems to be an excellent group to study the secrets of
longevity (Venturelli, Schena, & Richardson, 2012). Even though genetic factors play an
important role in terms of lifespan, the impact of modifiable lifestyle factors cannot be
underestimated (Perls and Terry, 2003).
The first studies on centenarians were conducted more than 100 years ago and the
importance of the lifestyle factor PA was already mentioned in the early research. Currently,
some scientists even argue that PA is the most important lifestyle factor in terms of disease
prevention and health in centenarians (Venturelli et al., 2012). Ozaki and colleagues (Ozaki,
Uchiyama, Tagaya, Ohida, & Ogihara, 2007) found health in centenarians to be significantly
correlated with PA and recommended regular PA for the very old. With this,
cardiorespiratory fitness and handgrip strength have shown to influence health and
independence in centenarians considerably (Franke, Margrett, Heinz, & Martin, 2012;
Paterson, Govindasamy, Vidmar, Cunningham, & Koval, 2004). However, more research is
necessary to come to a firm conclusion in terms of PA and healthy longevity, especially in
the very old because a recent study could not proof a correlation between PA habits and
longevity when independent very old people were compared with the normal population of
very olds (Rajpathak et al., 2011).
Physical activity recommendation for older adults
Based on the evidence of the beneficial health effects of PA for older adults and due to the
low PA levels in this population the American College of Sports Medicine and the American
Heart Association published PA recommendations for people aged 65 years or older (Nelson
et al., 2007). It is recommended that older adults perform either 30min of moderate aerobic
exercise on at least five days per week or 20min of vigorous aerobic activity on three days
weekly. Compared to the guidelines for adults under the age of 65 the intensity of the
activities for older adults is not absolute but subjective because of great individual differences
in functionality and fitness. Further, it is advised that older adults engage in moderate to high
intensity muscle-strengthening exercise using the major muscle groups on at least two
nonconsecutive days per week. Flexibility and balance exercise should be performed on a
regular basis as well (about two days per week for 20min) in order to improve functionality
and prevent falls. Finally, it is emphasized that greater amounts of PA also come with more
health benefits (Nelson et al., 2007).
The World Health Organization (WHO) also highlighted the positive health effects of
regular PA when they published their document on global PA recommendations for older
adults in 2010 (World Health Organization, 2010). These guidelines are similar to the
aforementioned. Additionally, the WHO mentions that even smaller amounts of PA are
beneficial for health and that it is therefore advisable to take a gradual stepwise approach
towards initiation and maintenance of PA based on individual capabilities (Chodzko-Zajko et
al., 2009; Taylor et al., 2004).
Physical activity participation in older adults
Despite the global release of PA guidelines and the widespread promotion of PA participation
in older age PA prevalence rates indicate a threatening picture. For England Taylor et al.
(2004) reported that only 13% of men and 10% of women between 65 and 85+ years are
walking brisk for at least 15min per day, while a strong decline was observed with increasing
age. Further, only about 10% are active at recommended levels with the strongest PA drop at
74 years. Data from the U.S. display a similar picture with older adults are generally less
active then younger groups (Chodzko-Zajko et al., 2009). Troiano et al. (2008) measured PA
with accelerometers in a large cohort and found that activity counts declined with age with
the lowest amount for people who are 60 years or older. Additionally, mean time spent in
vigorous intensity activities did not differ from zero, while moderate activities ranged from 6
to 10 minutes per day. Finally, only 2.4% of older adults adhered to the PA guidelines
mentioned earlier.
Low activity levels of older adults are not only present in global north countries as
shown by Abouzeid, Macniven and Bauman (2008) in their comprehensive work on the PA
levels in Asia-Pacific. Of the 24 countries that collected PA data of older adults 20 indicated
that PA declines with age and, that older adults are the least active group (data from China
was contradictory, but some surveys confirmed this trend). Surveys from Japan, Singapore,
Taiwan and Tokelau did not confirm this general trend.
Barriers and motivators of physical activity in older adults
The lack of PA in older adults and the associated consequences necessitated and still
necessitates research on barriers and enablers of PA participation in order to develop
sustainable promotion approaches. These factors or predictors are partly unique to older
adults and cannot be directly translated from other age groups. A comprehensive overview on
barriers and motivators of PA in older adults comes from a paper by Schutzer and Graves
(2004). While health issues, the environment, existing knowledge, self-efficacy, prompts and
certain demographic variables are strong predictors for PA participation in older adults the
researchers highlighted the key role of physicians in promoting PA among a population that
has frequent contact with their doctors (Schutzer & Graves, 2004).
The role of physicians in promoting PA in older adults
In 2010, a study by Hsiao, Cherry, Beattly and Rechtsteiner found that on average every U.S.
American visits his/her physician three times annually. The amount of visits is higher among
older adults (Rattay et al., 2013). The regular contact or care continuity for a variety of health
and even personal issues creates positive interaction and communication, and it generates a
relationship of trust. Particularly, older adults seem to value such a relationship (Pandhi &
Saultz, 2006). Hence, the physician who reaches many health-advice-seeking people can
influence lifestyle parameters, because patients consider their general practitioner (GP) as the
most trusted source for health information (Kreuter, Chheda, & Bull, 2000). Consequently,
physicians or other clinicians can and should play a key role in promoting PA in the general
population and especially in older adults who greatly benefit from more PA (Pinto, Goldstein,
Ashba, Sciamanna, & Jette, 2005).
Yet, only about one third of adult patients received counseling from their GPs to
increase PA (Eakin, Brown, Schofield, Mummery, & Reeves, 2007; Glasgow, Eakin, Fisher,
Bacak, & Brownson, 2001). A German study that examined the frequency of PA advice
given to older adults came to similar results as only one third of the 1937 patients reported
any PA counseling from their GP (Hinrichs et al., 2011). This study also confirmed earlier
findings highlighting that PA counseling is mostly given to patients who have health
problems (Eakin et al., 2007). Thus, the potential preventive impacts of PA are
underestimated among physicians.
Reasons for the low frequency of PA advice given by physicians are reported in
various research articles. Most prevalent barriers are:
Lack of time for PA advice during consultation
Lack of PA consultation skills, training and/or knowledge
Lack of institutional support
Little of no reimbursement for PA consultation
Competing demands of providing a broad range of preventive and non-
preventive services
Preference of patients for drug-treatment (Hinrichs et al., 2011; Tulloch,
Fortier, & Hogg, 2006; Wee, McCarthy, Davis, & Phillips, 1999)
PA topics under recognized in medical journals (Dupen, Bauman, & Lin, 1999)
These reasons are compelling, but so is the success of physical activity counseling
interventions carried out in primary care. The impact of PA counseling in the general
population was examined in a review by Tulloch, Fortier and Hogg (2006). The research
group found that 50% of the interventions that were based solely on physicians’ advice
changed PA behavior positively in short- and also long-term. Better results were reported
when the intervention was carried out by a health care professional or when physicians’
advice was combined with a health care professional intervention. For example, the effects of
a brief PA advice by physicians was compared with an extended PA advice intervention that
included face-to-face counseling with a health educator, tailored PA prescription, counseling
phone calls and mailed tip sheets in adults aged 65 years or older (Pinto et al., 2005).
Objective and subjective measures of PA indicated a significantly stronger increase of PA
after 3 and 6 months in the group that received the extended PA advice intervention. But also
the group that received only a brief PA advice for about 3 minutes increased their PA levels
considerably (e.g. 16.60 min/week increase compared to baseline). Thus, even low cost and
short time interventions can lead to desirable PA increments in older adults (Pinto et al.,
2005), while more comprehensive approaches seem to be more successful. Increasing PA in
older adults was also observed in a trial carried out in New Zealand that implemented a
system that allows physicians to prescribe PA (Green Prescription) (Kerse, Elley, Robinson,
& Arroll, 2005). Individuals who received a PA prescription that included individual PA
counseling with an exercise specialist, regular phone calls and newsletters increased their
leisure time PA and energy expenditure significantly after 12 months compared to a usual
care group. On average leisure time PA increased 40min per week, an effect that is modestly
stronger than in younger individuals.
In short, the evidence displays a relatively clear picture about the effectiveness of PA
counseling in primary care for older adults. Herein, PA advice from the personal physician
who has strong credibility marks the first step in raising PA levels and should become a
routine (Nelson et al., 2007). Furthermore, in order to effectively utilize the potential of PA
consultation a multidisciplinary team needs to be involved in the counseling process to
reduce the burden of the physicians and to increase sustainability via individual tailoring and
follow-up (Tulloch et al., 2006).
Physical activity is one of the strongest predictors of health and longevity in older adults.
Effects of PA are not limited to physiological outcomes, but also affect cognitive and mental
domains. The evidence clearly indicates that moderate to vigorous activities are best
associated with health and extended life span in older adults, whereas increases of PA up to a
certain level are responsible for elevated benefits. Individuals with low PA levels do also
benefit from less intense activities. Aerobic exercise appears to be the most important factor
for overall health, whereas strength training specifically improves the health of the
musculoskeletal system. Finally, PA and exercise are effective non-pharmaceutical and cost
effective means to promote successful aging and specific PA counseling should become
routine in primary care.

OBJECTIVE: To issue a recommendation on the types and amounts of physical activity needed to improve and maintain health in older adults. PARTICIPANTS: A panel of scientists with expertise in public health, behavioral science, epidemiology, exercise science, medicine, and gerontology. EVIDENCE: The expert panel reviewed existing consensus statements and relevant evidence from primary research articles and reviews of the literature. Process: After drafting a recommendation for the older adult population and reviewing drafts of the Updated Recommendation from the American College of Sports Medicine (ACSM) and the American Heart Association (AHA) for Adults, the panel issued a final recommendation on physical activity for older adults. SUMMARY: The recommendation for older adults is similar to the updated ACSM/AHA recommendation for adults, but has several important differences including: the recommended intensity of aerobic activity takes into account the older adult's aerobic fitness; activities that maintain or increase flexibility are recommended; and balance exercises are recommended for older adults at risk of falls. In addition, older adults should have an activity plan for achieving recommended physical activity that integrates preventive and therapeutic recommendations. The promotion of physical activity in older adults should emphasize moderate-intensity aerobic activity, muscle-strengthening activity, reducing sedentary behavior, and risk management. Language: en
WHO developed the Global Recommendations on Physical Activity for Health with the overall aim of providing national and regional level policy makers with guidance on the dose-response relationship between the frequency, duration, intensity, type and total amount of physical activity needed for the prevention of NCDs. The recommendations set out in this document address three age groups: 5-17 years old; 18-64 years old; and 65 years old and above. The section below includes the recommendations for each age group.

Context The increase in sedentary lifestyle may contribute to the rise in obesity nationally. Although guidelines suggest that physicians counsel all patients about exercise, physicians counsel only a minority of their patients. Whether patient factors influence physician counseling is not well established.Objectives To examine and to identify factors associated with exercise counseling by US physicians.Design and Setting National population-based supplemental (Year 2000) survey to the 1995 National Health Interview Survey.Participants Of the 17,317 respondents to the Year 2000 supplemental survey, 9711 adults had seen a physician in the previous year, and 9299 responded when asked about physician counseling on exercise.Main Outcome Measure Physician counseling to begin or to continue to exercise.Results Of 9299 respondents, 34% reported being counseled about exercise at their last visit. After adjustment for other sociodemographic and clinical factors, women were slightly more likely to be counseled, with an adjusted odds ratio (AOR) of 1.15 (95% confidence interval [CI], 1.02-1.29). Physicians counseled older patients (>30 years) more often than younger patients; those aged 40 to 49 years were counseled most often (AOR, 1.71 [95% CI, 1.34-2.20]). Patients with incomes above $50,000, those with higher levels of physical activity, college graduates, and patients who were overweight to obese (body mass index: 25 to ≥30 kg/m2) were more likely to be counseled, as were patients with cardiac disease (AOR, 1.81 [95% CI, 1.52-2.14]) and diabetes (AOR, 1.87 [95% CI, 1.46-2.38]). Counseling did not vary by physician specialty or patient race.Conclusion The rate of physician counseling about exercise is low nationally. Physicians appear to counsel as secondary prevention and are less likely to counsel patients at risk for obesity. The failure to counsel younger, disease-free adults and those from lower socioeconomic groups may represent important missed opportunities for primary prevention.
Weight-bearing physical activity has beneficial effects on bone health across the age spectrum. Physical activities that generate relatively high-intensity loading forces, such as plyometrics, gymnastics, and high-intensity resistance training, augment bone mineral accrual in children and adolescents. Further, there is some evidence that exercise-induced gains in bone mass in children are maintained into adulthood, suggesting that physical activity habits during childhood may have long-lasting benefits on bone health. It is not yet possible to describe in detail an exercise program for children and adolescents that will optimize peak bone mass, because quantitative dose-response studies are lacking. However, evidence from multiple small randomized, controlled trials suggests that the following exercise prescription will augment bone mineral accrual in children and adolescents: Mode: impact activities, such as gymnastics, plyometrics, and jumping, and moderate intensity resistance training; participation in sports that involve running and jumping (soccer, basketball) is likely to be of benefit, but scientific evidence is lacking Intensity: high, in terms of bone-loading forces; for safety reasons, resistance training should be <60% of 1-repetition maximum (IRM) Frequency: at least 3 d·wk-1 Duration: 10-20 min (2 times per day or more may be more effective) During adulthood, the primary goal of physical activity should be to maintain bone mass. Whether adults can increase bone mineral density (BMD) through exercise training remains equivocal. When increases have been reported, it has been in response to relatively high intensity weight-bearing endurance or resistance exercise; gains in BMD do not appear to be preserved when the exercise is discontinued. Observational studies suggest that the age-related decline in BMD is attenuated, and the relative risk for fracture is reduced, in people who are physically active, even when the activity is not particularly vigorous. However, there have been no large randomized, controlled trials to confirm these observations, nor have there been adequate dose-response studies to determine the volume of physical activity required for such benefits. It is important to note that, although physical activity may counteract to some extent the aging-related decline in bone mass, there is currently no strong evidence that even vigorous physical activity attenuates the menopause-related loss of bone mineral in women. Thus, pharmacologic therapy for the prevention of osteoporosis may be indicated even for those postmenopausal women who are habitually physically active. Given the current state of knowledge from multiple small randomized, controlled trials and large observational studies, the following exercise prescription is recommended to help preserve bone health during adulthood: Mode: weight-bearing endurance activities (tennis; stair climbing; jogging, at least intermittently during walking), activities that involve jumping (volleyball, basketball), and resistance exercise (weight lifting) Intensity: moderate to high, in terms of bone-loading forces Frequency: weight-bearing endurance activities 3-5 times per week; resistance exercise 2-3 times per week Duration: 30-60 min·d -1 of a combination of weight-bearing endurance activities, activities that involve jumping, and resistance exercise that targets all major muscle groups It is not currently possible to easily quantify exercise intensity in terms of bone-loading forces, particularly for weight-bearing endurance activities. However, in general, the magnitude of bone-loading forces increases in parallel with increasing exercise intensity quantified by conventional methods (e.g., percent of maximal heart rate or percent of 1RM). The general recommendation that adults maintain a relatively high level of weight-bearing physical activity for bone health does not have an upper age limit, but as age increases so, too, does the need for ensuring that physical activities can be performed safely. In light of the rapid and profound effects of immobilization and bed rest on bone loss, and the poor prognosis for recovery of mineral after remobilization, even the frailest elderly should remain as physically active as their health permits to preserve skeletal integrity. Exercise programs for elderly women and men should include not only weight-bearing endurance and resistance activities aimed at preserving bone mass, but also activities designed to improve balance and prevent falls. Maintaining a vigorous level of physical activity across the lifespan should be viewed as an essential component of the prescription for achieving and maintaining good bone health.
[Two of the authors respond:] We agree with Herbert Nehrlich that there are many situations in which physicians would benefit from the assistance of health and fitness professionals. It is essential that such advice be sought from professionals who have received formal training and attained national accreditation. In North America1 these would be professionals certified by the Canadian Society for Exercise Physiology or the American College of Sports Medicine. Together, physicians and health and fitness professionals will be able to provide information that is based on sound physiological principles and a clear knowledge of the absolute and relative contraindications to exercise for a variety of populations. Giuseppe Lippi and associates correctly point out that vigorous exercise may lead to supplemental health gains in sedentary community-dwelling individuals. There is growing evidence to suggest that certain groups may benefit greatly from high-intensity exercise training. We1 have advocated high-intensity exercise training for sedentary individuals2 and patients with cardiovascular disease3 and chronic heart failure.4 However, we are careful to acknowledge that adherence to this form of exercise may be poor and the risk of musculoskeletal injury higher. Therefore, we must weigh carefully the potential advantages and disadvantages of vigorous exercise for each individual client. As pointed out by Ediriweera Desapriya and colleagues, discussion of the barriers to exercise and innovative means to deliver inclusive and culturally appropriate physical activity interventions is of great importance. Furthermore, more effective lifestyle interventions are required to address the global crisis of physical inactivity. We have worked diligently to address the barriers to physical activity and have taken a transdisciplinary approach to the creation of novel exercise interventions. More work is required to “develop and deliver” inclusive interventions for all, but we believe that our work1,5 is a step in the right direction. As Rajesh Chauhan and associates point out, the determinants of health are multifactorial and physical activity is not the sole factor influencing health status. However, physical inactivity is an independent predictor of the risk for many chronic diseases and premature mortality. In fact, the risk for chronic disease and premature mortality in North America appears to be about 20% to 50% greater among those with a physically inactive lifestyle.5 Furthermore, physical activity appears to be protective in the presence of other known risk factors for chronic disease. Therefore, there is compelling evidence to support the independent health benefits of physical activity.
Ageing is a continuum of biological processes characterized by progressive adaptations which can be influenced by both genetic and physiological factors. In terms of human maturation, physically and cognitively functional centenarians certainly represent an impressive example of successful healthy ageing. However, even in these unique individuals, with the passage of time, declining lung function and sarcopenia lead to a progressive fall in maximal strength, maximal oxygen uptake, and therefore reduced exercise capacity. The subsequent mobility limitation can initiate a viscous downward spiral of reduced physical function and health. Emerging literature has shed some light on this multi-factorial decline in function associated with aging and the positive role that exercise and physical capacity can play in the elderly. Recognizing the multiple factors that influence ageing, the aim of this review is to highlight the recently elucidated limitations to physical function of the extremely old and therefore evaluate the role of exercise capacity in the health and longevity of centenarians.
