To assess the efficacy of moderate aerobic physical activity with sleep hygiene education to improve sleep, mood and quality of life in older adults with chronic insomnia.
Seventeen sedentary adults aged >or=55 years with insomnia (mean age 61.6 [SD±4.3] years; 16 female) participated in a randomized controlled trial comparing 16 weeks of aerobic physical activity plus sleep hygiene to non-physical activity plus sleep hygiene. Eligibility included primary insomnia for at least 3 months, habitual sleep duration <6.5h and a Pittsburgh Sleep Quality Index (PSQI) score >5. Outcomes included sleep quality, mood and quality of life questionnaires (PSQI, Epworth Sleepiness Scale [ESS], Short-form 36 [SF-36], Center for Epidemiological Studies Depression Scale [CES-D]).
The physical activity group improved in sleep quality on the global PSQI (p<.0001), sleep latency (p=.049), sleep duration (p=.04), daytime dysfunction (p=.027), and sleep efficiency (p=.036) PSQI sub-scores compared to the control group. The physical activity group also had reductions in depressive symptoms (p=.044), daytime sleepiness (p=.02) and improvements in vitality (p=.017) compared to baseline scores.
Aerobic physical activity with sleep hygiene education is an effective treatment approach to improve sleep quality, mood and quality of life in older adults with chronic insomnia.

    • "Previous research has demonstrated that various types of exercise training (e.g., 63 aerobic, strength, functional strength and flexibility) increase perceptions of HRQL in older 64 adults (King et al. 2000; Reid et al. 2010; Rejeski and Mihalko 2001). However, a minority of 65 studies have examined HRQL in response to high-intensity, interval-based activities, with 66 positive findings evident in ageing heart failure patients (Chrysohoou et al. 2014).

    ABSTRACT: There is a demand for effective training methods that encourage exercise adherence during advancing age, particularly in sedentary populations. This study examined the effects of high-intensity interval training (HIIT) exercise on health-related quality of life (HRQL), aerobic fitness and motivation to exercise in ageing men. Participants consisted of males who were either lifelong sedentary (SED; N = 25; age 63 ± 5 years) or lifelong exercisers (LEX; N = 19; aged 61 ± 5 years). [Formula: see text] and HRQL were measured at three phases: baseline (Phase A), week seven (Phase B) and week 13 (Phase C). Motivation to exercise was measured at baseline and week 13. [Formula: see text] was significantly higher in LEX (39.2 ± 5.6 ml kg min(-1)) compared to SED (27.2 ± 5.2 ml kg min(-1)) and increased in both groups from Phase A to C (SED 4.6 ± 3.2 ml kg min(-1), 95 % CI 3.1 - 6.0; LEX 4.9 ± 3.4 ml kg min(-1), 95 % CI 3.1-6.6) Physical functioning (97 ± 4 LEX; 93 ± 7 SED) and general health (70 ± 11 LEX; 78 ± 11 SED) were significantly higher in LEX but increased only in the SED group from Phase A to C (physical functioning 17 ± 18, 95 % CI 9-26, general health 14 ± 14, 95 % CI 8-21). Exercise motives related to social recognition (2.4 ± 1.2 LEX; 1.5 ± 1.0 SED), affiliation (2.7 ± 1.0 LEX; 1.6 ± 1.2 SED) and competition (3.3 ± 1.3 LEX; 2.2 ± 1.1) were significantly higher in LEX yet weight management motives were significantly higher in SED (2.9 ± 1.1 LEX; 4.3 ± 0.5 SED). The study provides preliminary evidence that low-volume HIIT increases perceptions of HRQL, exercise motives and aerobic capacity in older adults, to varying degrees, in both SED and LEX groups.

    • "Moderate intensity aerobic exercise has been associated with reduced polysomnographic measured: sleep onset latency, total wake time, number of awakenings, and amount of time spent in stage 1 sleep, while increasing total sleep time, sleep efficiency, and amount of time in stage 2 sleep (King et al., 2008; Passos et al., 2010). Moderate intensity exercise has also been shown to improve selfreported indices of sleep, including sleep quality, sleep latency, sleep duration, daytime dysfunction, and sleep efficiency (King, Oman, Brassington, Bliwise, & Haskell, 1997; Reid et al., 2010; Singh, Clements, & Fiatarone, 1997).

    ABSTRACT: Introduction Posttraumatic Stress Disorder (PTSD) is prevalent among military veterans and is associated with a number of negative outcomes. Despite available treatments, rates of recovery are poor and many symptoms persist post-treatment. Previous research suggests that exercise functions to reduce symptoms of anxiety and improve sleep quality, though its effects are understudied among those with PTSD. Method We sought to assess the extent to which exercise and sleep interactively impact changes in PTSD severity. Participants were 217 veterans in residential PTSD treatment who were offered the opportunity to participate in a bike-exercise program. Data were collected at treatment intake and discharge. Results Exercise (defined as total volume of cycling completed over the course of treatment) was associated with greater reductions in PTSD hyperarousal symptoms at discharge only among veterans with poor intake sleep quality. Conclusions Overall, exercise may be a beneficial adjunctive treatment for reducing hyperarousal symptoms among individuals with PTSD and poor sleep.

Importantly , even if sleep interventions ultimately have no impact on memory in older adults , improving sleep may still have several non - cognitive benefits including improved quality of life ( Arakawa , Tanaka , Toguchi , Shirakawa , & Taira , 2002 ; Faubel et al . , 2009 ; Reid et al . , 2010 ) , mental health ( Driscoll et al . , 2008 ; Tanaka et al . , 2001 ; 2002 ) , and longevity ( Dew et al . , 2003 ; Marin , Carrizo , Vicente , & Agusti , 2005 ) ."

    ABSTRACT: Sleep is implicated in cognitive functioning in young adults. With increasing age there are substantial changes to sleep quantity and quality including changes to slow wave sleep, spindle density, and sleep continuity/fragmentation. A provocative question for the field of cognitive aging is whether such changes in sleep physiology affect cognition (e.g., memory consolidation). We review nearly a half-century of research studies across 7 diverse correlational and experimental literature domains, which historically have had little crosstalk. Broadly speaking, sleep and cognitive functions are often related in advancing age, though the prevalence of null effects (including correlations in the unexpected, negative direction) in healthy older adults indicates that age may be an effect modifier of these associations. We interpret the literature as suggesting that maintaining good sleep quality, at least in young adulthood and middle age, promotes better cognitive functioning and serves to protect against age-related cognitive declines.
