26(10): 2777–2782, 2012—Because of the performance dec-
rements associated with delayed-onset muscle soreness
(DOMS), a treatment to alleviate its symptoms is of great inter-
est. The purpose of this study was to investigate the effect of low
vs. moderate-intensity aerobic recovery on DOMS and strength.
Twenty-six women (22.11 62.49 years; 60.33 68.37 kg; and
163.83 67.29 cm) were split into 3 different groups and per-
formed a DOMS-inducing protocol of 60 eccentric actions of
the knee extensors followed by 1 of three 20-minute recovery
interventions: moderate-intensity cycling (n= 10), low-intensity
cycling (LIC; n=10),orseatedrest(CON;n= 6) after the
eccentric protocol. Pain scale (PS), isometric strength (ISO),
and dynamic strength (PT) were recorded before (PRE), imme-
diately post (IP), 24- (24h), 48- (48h), 72- (72h), and 96- (96h)
hours after exercise. For PT, PRE, 48h, 72h, and 96h were
significantly (p,0.05) greater than IP values but not different
from 24h. For PS, IP (4.83 60.36) was greater than that for all
other time periods, whereas 24h (2.91 60.42), 48h (2.62 6
0.53), and 72h (1.97 60.49) were all greater than PRE (0.44 6
0.19) values. Also, 24h and 48h were not different but were both
greater than 72h and 96h (1.13 60.32), whereas 72h was
.96h. For ISO, neither CON nor LIC showed any significant
difference across time. Moderate-intensity cycling showed no
difference between PRE (189.88 640.68), IP (193.75 6
47.24), 24h (186.52 653.55), or 48h (195.36 655.06), but
72h (210.05 653.57) and 96h (207.78 659.99) were signif-
icantly .24h. The 72h was also greater than IP. Therefore,
moderate-intensity aerobic recovery may be suggested after
eccentric muscle actions.

INTRODUCTION
Unaccustomed exercise, primarily involving large
quantities of eccentric muscle actions, induces
muscle damage across a variety of populations
(12,20,24,25,26,27,29), including athletes (9).
This unaccustomed stress results in what is commonly
known as delayed-onset muscle soreness (DOMS). Namely,
DOMS is associated with pain, discomfort, and a decrease in
performance. Because of the performance decrements asso-
ciated with DOMS, a treatment to alleviate its symptoms is
of great interest to athletes, and coaches alike.
Coaches and researchers have implemented a variety of
strategies in an attempt to alleviate DOMS. Passive recovery
strategies abound in the literature. Some examples are
nutritional interventions (6,8,31,37), therapeutic modalities
such as ice (13), heat (3,5,13,17,30), and massage (15,19,38),
electrical stimulation (5), anti-inflammatory drugs (10,11,13),
and stretching (13). Additionally, active recovery has also
been considered during the search for effective treatment
strategies. Active recovery methods include light resistance
training (39), high-intensity resistance training (28), aquatic
exercise (32), warm-up and cool-down (18), whole-body
vibration (1,2), and low-intensity aerobic exercise (9). How-
ever, many of these demonstrate conflicting outcomes.
Although there is an abundance of research on passive
recovery strategies, research on active recovery is lacking.
The proposed rationale for the majority of the aforemen-
tioned active recovery interventions is that blood flow is
acutely increased in the treated area (9). As a result of this
increased blood flow, more waste is taken away from the
injured site, and more nutrients are delivered, accelerating
repair and remodeling (9). With even more blood flow, it
may be possible to speed up recovery. Eliciting greater blood
flow via exercise that elevates HR may encourage greater
healing. Among active recoveries, aerobic exercise seems
to be the most appropriate treatment strategy because it
increases blood flow without causing more muscle damage
that may occur with higher intensity exercises.
However, to our knowledge, few, if any, studies have
investigated the acute effect of different intensities of aerobic
activity on DOMS and strength. A recovery treatment that
demonstrates an acute recovery may be further investigated
to determine the chronic effect of that treatment. Therefore,

the purpose of this study was to investigate the acute effect
of low vs. moderate-intensity aerobic recovery on DOMS
and peak torque.
METHODS
Experimental Approach to the Problem
This between-groups study examined the effect of 2 different
intensities of aerobic activity on DOMS and strength. The
subjects performed a DOMS-inducing protocol on day 1
followed by 1 of 3 recovery interventions: moderate-
intensity cycling (MIC), low-intensity cycling (LIC), or
rest (CON). Delayed-onset muscle soreness and strength
were recorded immediately post (IP), 24- (24h), 48- (48h),
72- (72h), and 96- (96h) hours after the DOMS-inducing
eccentric protocol and compared with baseline (PRE)
measures.
Subjects
Twenty-six women were randomly assigned to 1 of 3
groups: MIC; n= 10 (21.80 62.66 years, 162.4 68.17 cm,
57.32 69.90 kg, ISO; 197.84 636.36 N$m
21
, and PT240;

), LIC; n= 10 (22.40 62.91 years,
163.35 67.56 cm, 60.46 65.34 kg, ISO; 189.88 6
40.68 N$m
21
, and PT240; 89.13 614.80 N$m

), or
CON; n= 6 (22.17 61.94 years, 167.00 66.04 cm,
65.12 69.48 kg, ISO; 217.77 634.70 N$m
21
, and PT240;
89.28 613.91 N$m
21
). All the subjects received, read, and
signed a University institutional review board–approved
informed consent before participation. No subjects had
incurred any recent musculoskeletal injury that may have
affected their performance. All the subjects were familiar
with and had experienced DOMS before. The subjects were
instructed to refrain from any physical activity outside of
the investigation and to sustain their normal diet and daily
activities (going to school, driving to work, etc.) for the
duration of the study. Additionally, they were instructed to
avoid any stretching, ice, heat, antiinflammatory drugs, or
any other type of recovery for the extent of the study. The
only methodological difference between groups was the
recovery intervention. Baseline (PRE) anthropometrics, iso-
metric, and dynamic strength were not different between
groups, minimizing within-group variance.
Procedures
For baseline testing (PRE), the subjects reported to the
laboratory, informed consent forms were signed, their mass
was measured using a digital scale (Model # ES200L, Ohaus,
Pine Brook, NJ, USA), and their height using a wall-mounted
stadiometer (Seca Stadiometer, Ontario, Canada). Resting
HR was taken after the subjects were seated for approxi-
mately 5 minutes. Baseline measurements included the fol-
lowing: pain scale (PS), peak isometric torque of the right
quadriceps at 608of knee flexion (full extension = 08) (ISO),
and peak torque of the right quadriceps at 2408$s
21
(PT).
After the PS measurement, the subjects were seated on a
cycle ergometer while wearing an HR monitor (Polar FT1,
Kempele, Finland). They cycled at 80 rpm for 5 minutes, and
the work rate was adjusted until the HR met the require-
ments of their assigned group. The CON subjects cycled at
approximately 50 W. This served as a warm-up before ISO
and PT testing and also as a trial for the investigators to
determine the load at which each subject would cycle during
their recovery intervention.
Within 1 week of PRE, the subjects reported back to
the laboratory for 5 consecutive experimental trial days (days
1–5). On day 1, they completed a 5-minute cycle warm-up at
50 W at a self-selected cadence. Next, they performed the
DOMS-inducing protocol, underwent testing again, and par-
ticipated in their appropriate recovery intervention. On days
2–5, the subjects reported back to the laboratory at the same
time as day 1 and performed the same tests.
Recovery Intervention
The MIC and LIC groups performed 20 minutes of cycling
at 80 rpm (16) on a stationary cycle ergometer (Monark
838E, Varberg, Sweden) after testing on day 1. Resistance
during the recovery intervention was adjusted to match
the desired HR. The MIC group cycled at 70% age-
predicted maximum HR reserve, while the LIC group cycled
at 30% age-predicted maximum HR reserve. The CON
group was seated on the cycle ergometer for 20 minutes
without pedaling with the pedals parallel and the right foot
in front.
Pain Scale
The participants rated their quadriceps pain on a scale of
0–10, adapted from McHugh and Tetro (0 = no pain to 10 =
extremely intense pain) (21).
Isometric and Dynamic Strength Testing
The subjects were seated on a Biodex System 3 isokinetic
dynamometer (Biodex Medical Systems, Shirley, NY, USA)
with the body stabilized by straps over the thighs, waist, and
chest and the right lateral epicondyle of the femur aligned
with the axis of rotation. Once in position, peak isometric

, in random order. For the isometric test, three
6-second maximal isometric actions of the knee extensors
were performed, separated by 2 minutes of rest (4).
Two minutes of rest was also given between the isometric
and dynamic trials. Dynamic trials were performed with the
range of motion set to 108of knee extension and 908of knee
flexion. The subjects performed 6 maximal concentric recip-
rocal repetitions of the knee extensors and flexors. They did
not receive any visual feedback but were verbally encour-
aged throughout the duration of testing.
Eccentric Protocol
The subjects were securely positioned at 908knee flexion
for unilateral knee extension and flexion of the right leg on
the dynamometer. They performed 6 sets of 10 maximal
eccentric actions of the right knee extensors at 608$s
21
(1)
with the range of motion set to 108of knee extension and 908
of flexion with the dynamometer in continuous passive
mode. They returned to the extended position passively
between each eccentric action of the knee extensors.
One minute of rest was allotted between sets.
Statistical Analyses
Three 3 36 (group 3time) mixed-factor analyses of vari-
ance (ANOVAs) were used to analyze PS, ISO, and PT using
SPSS Version 20 (Statistical Package for Social Sciences,
Chicago, IL, USA). An a-priori alpha level of 0.05 was con-
sidered statistically significant.
RESULTS
Pain scale demonstrated no interaction (Figure 1), but there
was a main effect for time (effect size = 0.51). Immediately
postexercise value was greater than all other time periods’
values, whereas 24h, 48h, and 72h were all significantly
greater than PRE. Values of 24h and 48h were not different

from each other but were both greater than those of 72h and
96h, whereas 72h was also .96h (Figure 2).
Dynamic strength demonstrated no interaction (Figure 3),
but there was a main effect for time (effect size = 0.11). The
PRE was significantly greater than IP but was not different
from 24h, 48h, 72h, or 96h, whereas 48h, 72h, and 96h were
also significantly greater than IP but were not different from
24h (Figure 4).
The ISO demonstrated a significant time 3group inter-
action (effect size = 0.15). This was followed up with three
136 ANOVAs for each group. The CON and LIC showed
no significant differences across time. The MIC showed no
difference between PRE, IP, 24h, or 48h, but 72h and 96h
were significantly .24h, whereas 72h was also greater than
IP (Figure 5).
DISCUSSION
Unaccustomed bouts of eccentric exercise often result in
DOMS. Because of the performance decrements associated
with DOMS, a treatment to alleviate its symptoms is of great
interest to athletes, coaches, and researchers. The purpose of
this study was to investigate the effect of different aerobic
recovery intensities on DOMS and strength. Our results
showed that DOMS significantly increased immediately
after eccentric exercise and remained elevated for 3 days,
whereas dynamic strength decreased immediately after and
returned to baseline 2 days later. Additionally, isometric
strength remained constant in the CON and LIC groups, but
it increased 3 days after in the MIC group. It is possible that
despite inducing muscle soreness, the MIC group gained
isometric strength throughout the week as a result of cycling
at a greater intensity, which resulted in increased blood flow
to the muscles, aiding in the removal of waste products and
the delivery of nutrients. Also, the MIC, coupled with
a short-term training effect (daily testing), may be partially
responsible for the increase in isometric strength seen in the
MIC group.
The subjects in our study reported the greatest soreness
immediately after exercise. Similar to other studies, soreness
subsided 24–48 hours after exercise, but it was still signifi-
cantly greater than that at baseline (6,13,34). Despite prior
familiarization with the PS, the increase in soreness imme-
diately postexercise may have been misconstrued by the
subjects because of the intense effort of the eccentric pro-
tocol. Nonetheless, soreness was significantly greater than
baseline at 24- and 48 hours postexercise, indicating that
the protocol sufficiently induced DOMS.
The immediate decline in dynamic strength in our study
mimics the results of Close et al. (6), where dynamic torque
returned to baseline 48 hours after exercise. This can be
explained by the findings of Nguyen et al. (23), which elu-
cidate that DOMS and muscle performance are not always
comparable and can return to baseline at different times.
Further, Close et al. also showed that concentric and eccen-
tric strength recovered from eccentric exercise at different
rates (6). This may explain why, in our study, isometric and
dynamic strength were not affected by eccentric exercise in
the same way.
The MIC group did not exhibit a decrease in isometric
strength; rather, they exhibited an increase 3–4 days after
eccentric exercise. This may be explained by an increase of
muscle perfusion during the MIC intervention, possibly aid-
ing in the removal of waste products and in the deliverance
of nutrients. Davis et al. (9) reported a decrease in soreness
over time as a result of increasing the HR during interset rest
periods (and, in turn, an entire resistance training session)
when compared with resting during interset rest periods.
They speculated that elevating the HR before each set of
exercise enhanced muscle perfusion, accelerated H+ release,
and increased nutrient delivery, accelerating tissue repair.
Metabolic byproducts from high-intensity exercise can be
detrimental to subsequent performance (22,35). One conse-
quence of high-intensity exercise is H+ ions from lactate,
which can disrupt contractile mechanisms of skeletal muscle
(22). Removing lactate and its resultant H
+
can be acceler-
ated by increasing skeletal muscle blood flow (22). In our
study, the MIC may have experienced greater levels of
metabolic byproduct removal compared with that in the
CON and LIC groups as a result of their elevated HR and
increased cardiac output (16,33).
To further examine the effects of blood flow on muscle
recovery, 2 studies noted that blood flow restriction signif-
icantly reduced the amount of repetitions completed during
resistance exercise when compared with a normal blood
flow condition (35,36). Additionally, Hannie et al. (14)
observed enhanced dynamic strength recovery after a fatigu-
ing bench-press exercise by performing aerobic exercise
between sets. They observed no change in isometric
strength, although improvements were made in dynamic
strength after recovery, whereas our study showed improve-
ments in isometric strength and no change in dynamic
strength after recovery. Although the data from Hannie
et al.’s study (14) and our study are incongruous, the discrep-
ancies may be attributed to the difference in exercise and
recovery protocols. In contrast to our study, they used an
upper-body multijoint exercise, whereas our study used a sin-
gle joint lower-extremity exercise. Conclusively, reduced
blood flow impairs skeletal muscle performance (35,36),
whereas the active recovery in our study demonstrated
enhanced isometric strength at 72- and 96-hour recovery (14).
Increased blood flow to the muscles, by itself, may not
fully explain the increase in isometric torque experienced by
our MIC group. An increase in isometric strength in the
MIC group may also possibly be explained by a short-
term training effect. In a study conducted by Brown and
Whitehurst (4), the subjects performed 3 sets of 8 reciprocal
isokinetic knee extensions and flexions, on 2 occasions
within in 1 week. Their results indicated that the subjects
experienced a velocity-specific increase in rate-of-velocity-
development without an accompanying increase in strength.

To further investigate the effect of short-term training on
dynamic performance, Coburn et al. conducted a similar
study but increased training volume to 4 sets of 10 and
increased the frequency to 3 days (7). Contrary to Brown
and Whitehurst’s results (4), their results showed an increase
in strength. Therefore, the increase in strength observed
by Coburn et al. (7) may be explained by the increase of
volume during training, compared with that of Brown and
Whitehurst (4). In our study, the subjects performed 3 max-
imal isometric and 6 maximal dynamic muscle actions per
day, for a total of 6 days. These testing procedures resulted
in volumes equaling 18 maximal isometric actions and
36 maximal dynamic extensions of the quadriceps over
approximately 1 week which, when combined with greater
intensity aerobic activity, may have been sufficient to elicit
a short-term training effect. Although neither of the afore-
mentioned studies investigated isometric strength, it may be
postulated that isometric training, when combined with
MIC, might produce similar short-term increases because
of specificity of training.
PRACTICAL APPLICATIONS
Enhanced blood perfusion during moderate-intensity aero-
bic recovery, in conjunction with a short-term training effect,
may enhance isometric strength after DOMS. Therefore,
moderate intensity aerobic activity is suggested as a recovery
method after multiple eccentric muscular actions. Further
research should be conducted to determine the chronic
effects of moderate-intensity aerobic recovery after resis-
tance training.

... The last 2 findings support the use of active recovery not just for the physiological benefits already mentioned but also for positive perceptual and psychological considerations (26). Nonetheless, several active protocols have shown controversial findings regarding the choice of intensity, duration, and type of exercise (18,36,41,46,48,51). To our present knowledge, there are no other reviews that have provided an exclusive and indepth analysis of active recovery methods to improve performance after EIMD. ...
... Studies were categorized according to the type of recovery protocol and summarized in Table 2. The categories are as follows: isolated muscle contractions (19,43,57), cycling or arm cranking (1,18,35,48,52), stretching (4,54,56), general physical activity (25,28,32), exercise in water (46,51), and yoga (3). All recovery protocols were performed on the same group of muscles that had induced damage. ...
... All studies measured soreness whether through scales, algometer, or questionnaire. Muscle performance parameters such as maximal voluntary contraction (MVC), countermovement jump (CMJ), peak torque (PT), total work (TW), angle of PT, muscle power, stretch-shortening cycle (SSC), sprint time, and dynamic fatigue were measured in 12 studies (1,4,18,19,35,45,48,49,51,52,56,57). Seven studies assessed inflammatory markers: CK (1,4,25,45,48,51,57), myoglobin (25,51), lactate dehydrogenase (51), urea, and uric acid (1). ...
... Studies that investigated the effects of active recovery on EIMD have found conflicting results, partially explained by the variability between active recovery protocols, which use different volumes, intensities and type of exercises. Low and moderate intensity endurance exercises, such as running (Chen et al., 2007;Chen, Nosaka, & Wu, 2008;Law & Herbert, 2007;Martin, Millet, Lattier, & Perrod, 2004) and cycling (Andersson et al., 2008;Bahnert, Norton, & Lock, 2013;Dannecker, Koltyn, Riley, & Robinson, 2002;Gulick, Kimura, Sitler, Paolone, & Kelly, 1996;Olsen, Sjohaug, van Beekvelt, & Mork, 2012;Tufano et al., 2012;Weber, Servedio, & Woodall, 1994), have been widely used in regenerative training sessions in different sports and competitive levels due to its popularity and easy implementation. ...
... As a result of the type of contraction, these two active recovery modalities have different metabolic demands and muscle activation patterns, since eccentric contractions can generate more torque while having lower metabolic cost, muscle activation and cardiovascular stress (Howatson & van Someren, 2008). The influence of the exercise intensity performed during active recovery has already been investigated (Chen et al., 2008;Tufano et al., 2012). However, one question remains unknown: what is the best type of exercise for post-exercise recovery? ...
... Furthermore, different volumes of exercise for recovery exercise can be investigated. Volumes of 30 and 20 min of cycling at moderate intensities were positive in the present study and in the study by Tufano et al. (2012), respectively. Shorter periods can be evaluated to verify if they are capable of promoting beneficial effects as well. ...

Objective To compare the effects of moderate intensity running and cycling on markers of exercise-induced muscle damage in men. Study Design Randomized controlled trial. Setting Laboratory. Participants Thirty volunteers were randomized in three groups [running (RG; n=10), cycling (CG; n=10) and control (CON; n=10)] and were evaluated at baseline, post 24, 48 and 72h of knee extensors’ muscle damage protocol. CON performed passive recovery, while RG and CG performed active recovery immediately after the protocol, as well as 24h and 48h afterwards. Main outcomes (i) maximal voluntary isometric contraction (MVIC); (ii) delayed-onset muscle soreness (DOMS); (iii) plasma creatine kinase (CK) and lactate dehydrogenase (LDH) levels. Results No group-by-time interaction was found in any outcome evaluated (p>0.05). All groups presented decreases in MVIC and increases in DOMS (p<0.001), without differences in CK and LDH. Compared with CON, exercise groups presented likely beneficial effects for LDH, while only CG had a likely beneficial effect for DOMS. Lastly, CG presented likely/very likely beneficial effects for MVIC and DOMS compared to RG. Conclusion Although the null hypothesis analysis did not find differences, the magnitude-based inference analysis suggested that moderate intensity cycling have likely beneficial effects on knee extensor muscle recovery after eccentric exercise protocol.
... 13 A recent study also concluded that a session of high-intensity interval exercise [90% of maximal velocity (MV)] has similar effects as a continuous protocol (60% MV) on DOMS at 24h. 14 Moreover, light and moderate exercise intensities following EIMD did not show great improvements on recovery and muscle performance. 6,10, [15][16][17] Therefore, the choice of appropriate intensity appears to be inconclusive, and a particular threshold for higher intensities could offer potential advantages for better recovery and an optimal response in tissue remodeling. ...
... 8,24 Hence, this controversy could be related to our u-HIIE protocol, since the vast majority of studies that have examined active recovery modes on performance applied light to moderate intensities. 17,25,26 Regarding pain level, our results are similar to other previous studies which included endurance exercise at lower intensities as a recovery tool. Olsen et al did not find significant differences neither in VAS nor in pressure pain threshold (PPT) following 20 min of moderate-intensity (60-70% HRmax) cycling exercise, in comparison with a passive-recovery group. ...
... 16 Likewise, Tufano et al did not observe statistically significant interactions on a pain scale when applied a similar recovery protocol (20-min cycling) after a EIMD of the knee extensors, independently of exercise intensity (30% vs. 70% HRmax vs. sitting). 17 However, Hasson et al found a significant reduction in soreness at 48h after performing a recovery protocol consisting of knee flexion-extension voluntary contractions at high-speed (~300º/s). 13 The speed of execution could be the key factor in muscle recovery, suggesting that higher intensities may lead to accelerate it, since it has been described a directly proportional relationship between movement velocity and exercise intensity. ...

Background: Active recovery is believed to offer positive benefits related to exercise by improving recovery and potentially managing several symptoms following strenuous exercise. The current study aimed to verify the effects of a session of low-volume and uphill high-intensity interval exercise on muscle soreness and exercise performance within the recovery period after an exercise-induced muscle damage protocol. Methods: Thirty-one young physically active subjects completed two identical test sessions following an exercise-induced muscle damage protocol, separated by a threeweek period, in which they performed uphill high-intensity interval exercise or a passive recovery. The uphill high-intensity interval exercise consisted of 4 bouts of 30 seconds at maximum velocity, interspersed by 4 minutes of passive rest on an uphill treadmill. Rating of perceived exertion, muscle soreness, serum concentration of Creatine Kinase, muscle circumference, countermovement jump, sprint time, and 1 repetition maximum strength of quadriceps femoris were measured. The assessments were made for 4 consecutive days, before the exercise-induced muscle damage protocol and 24, 48, and 72 hours afterwards. Results: A significant effect of time was found for all the outcome measures, but there were no significant differences between groups either in pain perception, muscle damage variables, nor in performance outcome measures at any point of time (p>0.05). Conclusions: Uphill high-intensity interval exercise performed after an exerciseinduced muscle damage protocol does not exacerbate muscle soreness or worsens exercise performance in comparison with passive recovery.
... Several strategies can be used to manage and alleviate DOMS. One of the most effective is to engage in regular low-intensity aerobic exercise, such as walking or swimming (Tufano et al., 2012). This type of exercise can help to increase blood flow to the muscles, which can reduce inflammation and soreness. ...
... Aerobic exercises are not typically associated with DOMS. Aerobic exercise involves using large muscles in the body, such as the legs and arms, in a continuous and rhythmic manner (Tufano et al., 2012). Examples of aerobic exercise include running, cycling, swimming, and dancing. ...

Delayed onset muscle soreness (DOMS) is a type of muscle pain that typically occurs a day or two after engaging in physical activity that in- volves unaccustomed or strenuous muscle contractions. The exact cause of DOMS is not fully understood, but it is thought to be related to mi- croscopic damage to the muscle fibers and surrounding tissue, as well as inflammation in the muscle. There are several strategies that can be used to manage DOMS, including rest, streching, cold and heat modalities, medications, massage and exercise. It is important to note that DOMS is a normal response to physical activity and usually resolves on its own within a few days. However, if the pain persists or is severe, it is important to seek medical attention. In this review, we aimed to compile the most recent studies related to DOMS.
... For stretching, two studies (Ozmen (Boobphachart et al., 2017;Lightfoot et al., 1997;Rhea et al., 2009;Torres et al., 2013;Wessel & Wan, 1994;Xie et al., 2018). Finally, seven studies (Akinci et al., 2020;Andersen et al., 2013;Hart et al., 2005;Olsen et al., 2012;Ozmen et al., 2017;Rey et al., 2012;Zainuddin et al., 2006) showed significant outcomes regarding active exercise, while nine studies did not observe effects (Changa et al., 2020;Isabell et al., 1992;Law & Herbert, 2007;Marquet et al., 2015;Tufano et al., 2012;Wang et al., 2006;Weber et al., 1994;Wheeler & Jacobson, 2013;Wiewelhove et al., 2018). Forty-two studies were included in the analysis that examined the effects of mechanical methods compared to the no intervention for DOMS treatment. ...

Article
Objective To evaluate the impact of interventions on pain associated with DOMS. Data sources PubMed, EMBASE, PEDro, Cochrane, and Scielo databases were searched, from the oldest records until May/2020. Search terms used included combinations of keywords related to “DOMS” and “intervention therapy”. Eligibility criteria Healthy participants (no restrictions were applied, e.g., age, sex, and exercise level). To be included, studies should be: 1) Randomized clinical trial; 2) Having induced muscle damage and subsequently measuring the level of pain; 3) To have applied therapeutic interventions (nonpharmacological or nutritional) and compare with a control group that received no intervention; and 4) The first application of the intervention had to occur immediately after muscle damage had been induced. Results One hundred and twenty-one studies were included. The results revealed that the contrast techniques (p = 0,002 I² = 60 %), cryotherapy (p = 0,002 I² = 100 %), phototherapy (p = 0,0001 I² = 95 %), vibration (p = 0,004 I² = 96 %), ultrasound (p = 0,02 I² = 97 %), massage (p < 0,00001 I² = 94 %), active exercise (p = 0,0004 I² = 93 %) and compression (p = 0,002 I² = 93 %) have a better positive effect than the control in the management of DOMS. Conclusion Low quality evidence suggests that contrast, cryotherapy, phototherapy, vibration, ultrasound, massage, and active exercise have beneficial effects in the management of DOMS-related pain.

Ermüdung und Regeneration sind integrale Bestandteile des Trainingsprozesses. Dabei steht die kontinuierliche Leistungsentwicklung in ständiger Wechselwirkung mit den durch Trainings- und Wettkampfaktivitäten ausgelösten Ermüdungs- und Regenerationsvorgängen. Während die Steigerung der Trainingsqualität seit jeher im Fokus trainingswissenschaftlicher Bemühungen steht, richtet sich das Augenmerk zunehmend auch auf die Erholungsprozesse und deren Optimierung. Das Regenerationsmanagement lässt sich dabei im Wesentlichen in die Messung des Regenerationsbedarfs sowie in die individualisierte Planung und Anwendung von Regenerationsstrategien strukturieren. Hierbei ist die Bedeutung einer angemessenen Ernährung sowie von ausreichend Schlaf unbestritten. Zusätzlich kann in der (leistungs-)sportlichen Praxis aus einer Vielzahl an regenerationsfördernden Maßnahmen ausgewählt werden, deren Wirksamkeitsnachweis jedoch nur selten unter wissenschaftlich kontrollierten Bedingungen überzeugend erfolgt ist. Dies gilt sowohl für „traditionelle“ und bei den Athleten beliebte Maßnahmen wie beispielsweise die Massage als auch für neuartige Regenerationstrends wie Foam-Rolling oder für technologisch unterstützte Interventionsstrategien wie z. B. LED-Bestrahlung oder Kältekammern. Sowohl Ermüdungs- als auch Erholungsprozesse sind äußerst komplexe und multifaktorielle Phänomene, die in Abhängigkeit von den Belastungsmerkmalen sowie adressaten- und umweltspezifischen Besonderheiten auf verschiedenen Funktionsebenen des menschlichen Organismus (u. a. Muskulatur, Bindegewebe, zentrales Nervensystem, autonomes Nervensystem, endokrines System) in unterschiedlichen zeitlichen Dimensionen sowie in unterschiedlicher Geschwindigkeit und Ausprägung stattfinden. Basierend hierauf werden in diesem Kapitel sowohl die Wirkmechanismen und Effekte von Regenerationsinterventionen, die sich in der Sportpraxis großer Beliebtheit erfreuen, diskutiert als auch Grundlagen zum Ernährungsmanagement im Sport besprochen. Unter Berücksichtigung individueller und sportartspezifischer Rahmenbedingungen werden Praxistipps für die Regenerationssteuerung im (Leistungs-)Sport vorgestellt.
... Couple weeks of rehabilitative cycling with positive outcome is not enough time for the proprioceptive nerves to regenerate, maintain, not to mention enhance 'breathing capacity' . Important to note, that the above moderate intensity low resistance stationary cycling without substantial proprioceptive loading is recommended after eccentric muscle actions [62], rehabilitation sessions and at the end of the day, but not as late to interfere with sleeping, because lack of sleeping is also a very important risk factor of neuronal regeneration. ...

Background: Anterior cruciate ligament injury arises when the knee anterior ligament fibers are stretched, partially torn, or completely torn. Operated patients either end up re-injuring their reconstructed anterior cruciate ligament or majority develop early osteoarthritis regardless of the remarkable improvements of surgical techniques and the widely available rehabilitation best practices. New mechanism theories of non-contact anterior cruciate ligament injury and delayed onset muscle soreness could provide a novel perspective how to respond to this clinical challenge. Main body: A tri-phasic injury model is proposed for these non-contact injuries. Mechano-energetic microdam-age of the proprioceptive sensory nerve terminals is suggested to be the first-phase injury that is followed by a harsher tissue damage in the second phase. The longitudinal dimension is the third phase and that is the equivalent of the repeated bout effect of delayed onset muscle soreness. Current paper puts this longitudinal injury phase into perspective as the phase when the long-term memory consolidation and reconsolidation of this learning related neuronal injury evolves and the phase when the extent of the neuronal regeneration is determined. Reinstating the mitochondrial energy supply and 'breathing capacity' of the injured proprioceptive sensory neurons during this period is emphasized, as avoiding fatigue, overuse, overload and re-injury. Conclusions: Extended use, minimum up to a year or even longer, of a current rehabilitation technique, namely moderate intensity low resistance stationary cycling, is recommended preferably at the end of the day. This exercise therapeutic strategy should be a supplementation to the currently used rehabilitation best practices as a knee anti-aging maintenance effort.
... Caffeine has a greater effect on resistance exercise than aerobic exercise in terms of reducing muscle soreness within 24 h. It is possible that despite inducing muscle soreness, aerobic exercises, such as cycling or running, which increase the blood flow to the muscles, are better able to remove waste products and deliver nutrients to muscles (Tufano et al. 2012). Therefore, caffeine has no effect on this kind of exercise, but it is effective in reducing muscle pain in people who perform resistance exercise. ...

Background There are multiple strategies that have been suggested to attenuate delayed-onset muscle soreness (DOMS). Caffeine has been shown to assist with blocking pain associated with DOMS. However, currently there is still controversy over the effects of caffeine use. Main body We conducted a meta-analysis to compare pain associated with muscle soreness by both the VAS and indirect markers by CK of caffeine and placebo after exercise. The meta-analysis was carried out in accordance with the PRISMA guidelines. Relevant studies from Medline and Scopus published up to May 20, 2021, were included, which resulted in a total of 477 and 132 studies being retrieved from Scopus and Medline, respectively. Seven studies met the inclusion criteria, and in these, there were 68 persons in the caffeine group and 74 persons in the placebo group. A visual analog score of muscle soreness was recorded pre-exercise, immediately post-exercise, and at one to four days post-exercise; the scores at these time points in the caffeine group as compared to those in the placebo group progressed from 0.00 (95% CI − 0.51, 0.50) to − 0.20 (− 1.09, 0.69), − 0.92 (− 2.20, 0.36), − 1.02 (− 1.86, − 0.19), 0.00 (− 0.36, 0.36), and 0.18 (− 0.56, 0.92), respectively. No statistically significant differences were noted for CK between the two groups at 24 h post-exercise. Short conclusion Our meta-analysis results indicate that caffeine supplements reduce delayed-onset muscle soreness when compared to a placebo 48 h after exercise. However, at 24 h post-exercise, caffeine can reduce DOMS only in people who worked on resistant exercise. The CK used in this meta-analysis did not show any differences.

Abstract Purpose/Background: During intense exercise, muscles generate and release large quantities of blood lactate during anaerobic and resistance based exercise. As a result of intense periods of exercise and physical activity, blood lactate levels and the perception of muscle soreness increases, resulting in an acute decrease in athlete performance. The experience of an acute decrease in athletic performance and increase in negative physiological characteristics is referred to as delayed onset muscle soreness (DOMS). Since the beginning of sports science research, many researchers have tried to create methods to reduce and mitigate the effects of DOMS post exercise. Some of the most common methods include, stretching, massage, ice massage and cold-water immersion, electrical muscle stimulation, kinesiotaping and low-intensity exercise. However, there is currently little evidence to suggest which recovery intervention is best for treating the effects of DOMS. Subsequently, the aim of this present work is to perform a systematic review and meta-analysis evaluating the impact of different recovery techniques on delayed onset muscle soreness. Methods: A systematic literature search on articles published up to 20 September 2022 was carried out in the databases PubMed (MEDLINE), Scopus, SPORTDisscus. Additionally, academic search engines Google Scholar and ResearchRabbit were used to find additional studies. A search strategy was developed based on the Pico model to identify high quality literature that met the following inclusion criteria: (1) articles must have been published between 1940-2022 and written in English; (2) a recovery intervention was used either pre or post DOMS; (3) studies must have used at least one physiological or biomechanical outcome measure to assess the effect of a particular intervention against a control group (either a separate group of people or an untreated muscle on the same individual); (5) a full-text version of the study had to be publicly available with public access to all data used within the study. Using all of the extracted data from the included studies, this meta-analysis will use blood lactate levels, creatine kinase levels, muscle soreness, counter movement jump, maximal isometric voluntary contraction and range of movement. In order to try and answer the primary research aim of what recovery intervention can best mitigate the effects of DOMS. Results: A total of 275 studies met the inclusion criteria and were used in the systemic review and meta-analysis. The results show that there were significant differences between all of the individual outcome measures, however, once all the results were averaged together to create an overall recovery score, the differences between the interventions were less significant. The results also suggest that some particular recovery interventions have a more pronounced effect for mitigating certain symptoms of DOMS compared to other recovery interventions. When averaging all the results from all of the outcome measures, the pre-DOMS foam roller intervention had the greatest ability to mitigate the effects of DOMS. The second-best recovery intervention overall was dry needling. Both light pressure instrument assisted soft tissue mobilisation technique and flossing reported an average negative Cohen’s D value which was significantly below the baseline value reported by the control group which suggests that light pressure instrument assisted soft tissue mobilisation technique and flossing are not good recovery interventions for dealing with delayed onset muscles soreness. However, cryotherapy was the best recovery method for reducing blood lactate levels post DOMS. For the self-reported muscle soreness outcome measure, the post DOMS foam roller recovery intervention had the largest pronounced effect. For the CMJ outcome measure, pulsed ultrasound provided the greatest reduction in the effects of DOMS and increased the rate of recovery more than any other recovery intervention. For nearly all the chosen outcome measures within this meta-analysis there was a significant interaction between time and the magnitude of DOMS, meaning that after a single bout of the recovery intervention the magnitude of DOMS decreased at every data collection time point. However, not all recovery protocols were able to increase the rate of recovery more than was observed from the control group for each outcome measure. Future research should aim to explore the role of combined recovery techniques to investigate whether a synergetic phenomenon occurs when treating the effects of DOMS.

Background Delayed onset of muscle soreness (DOMS) is a common finding in trained and untrained individuals post high intensity exercises which can lead to injuries. Foam rolling (FR) and neurodynamic therapy (NDT) are types of active cool-down which provides effective for treatment of DOMS. But their role in reduction of intensity of the same in cool down is not established. Study design Crossover study Methodology Total 60 healthy individuals participated in the study. Pre intervention readings were taken of strength and tightness by Range of motion. Subjects performed both the types of cool-down separated by 4 weeks interval with random allocation. Post intervention readings of hamstring and quadriceps tightness, grade of tenderness and stand to sit VAS score was taken post 24 hours and 48 hours and strength post 48 hours. Results Analysis was done for using repeated measures ANOVA and Friedman’s test. The difference of values for Straight Leg Raise and Prone knee Flexion between NDT and FR post 24 hours were statistically significant (p<0.05) while that of NDT post 24 hours being similar to FR post 48 hours (p>0.05). There was a significant difference between strength, tenderness and VAS in NDT and FR (p<0.05). With the mean of post 24 hours as well as post 48 hours being less in the FR intervention. Conclusion Foam rolling is a better option than Neurodynamic therapy for reduction of intensity of DOMS.

This study examined the relation between pedal frequency and cardiovascular responses during arm (AE) and leg (LE) ergometry. Twenty-six subjects completed three experimental sessions. Each session consisted of 10 min of steady-state exercise on AE or LE at 40, 60, or 80 rev·min−1. Oxygen uptake (VO2) and cardiac output (Q) were measured during each exercise. Arteriovenous oxygen difference (a-vO2diff) was calculated by dividing VO2 by Q. VO2 was greater at 80 than at either 40 or 60 rev·min−1 during both AE and LE. Q was greater at 60 than 40 rev·min−1 during AE and at 80 than 40 rev·min−1 during LE. a-vO2diff was greater at 80 than 40 or 60 rev·min−1 during AE, but remained unchanged during LE. It appears that the greater VO2 at 80 rev·min−1 during AE is due to an increase in peripheral O2 extraction. However, an enhanced systemic circulation may be the principal cause for the greater VO2 seen at 80 rev·min−1 during LE.

Numerous recovery strategies have been used in an attempt to minimize the symptoms of delayed-onset muscle soreness (DOMS). Whole-body vibration (WBV) has been suggested as a viable warm-up for athletes. However, scientific evidence to support the protective effects of WBV training (WBVT) on muscle damage is lacking. To investigate the acute effect of WBVT applied before eccentric exercise in the prevention of DOMS. Randomized controlled trial. University laboratory. A total of 32 healthy, untrained volunteers were randomly assigned to either the WBVT (n = 15) or control (n = 17) group. Volunteers performed 6 sets of 10 maximal isokinetic (60°/s) eccentric contractions of the dominant-limb knee extensors on a dynamometer. In the WBVT group, the training was applied using a vibratory platform (35 Hz, 5 mm peak to peak) with 100° of knee flexion for 60 seconds before eccentric exercise. No vibration was applied in the control group. Muscle soreness, thigh circumference, and pressure pain threshold were recorded at baseline and at 1, 2, 3, 4, 7, and 14 days postexercise. Maximal voluntary isometric and isokinetic knee extensor strength were assessed at baseline, immediately after exercise, and at 1, 2, 7, and 14 days postexercise. Serum creatine kinase was measured at baseline and at 1, 2, and 7 days postexercise. The WBVT group showed a reduction in DOMS symptoms in the form of less maximal isometric and isokinetic voluntary strength loss, lower creatine kinase levels, and less pressure pain threshold and muscle soreness (P < .05) compared with the control group. However, no effect on thigh circumference was evident (P < .05). Administered before eccentric exercise, WBVT may reduce DOMS via muscle function improvement. Further investigation should be undertaken to ascertain the effectiveness of WBVT in attenuating DOMS in athletes.

Objectives: The purpose of this study was to investigate the physiological and psychological effects of massage on delayed onset muscle soreness (DOMS). Methods: Eighteen volunteers were randomly assigned to either a massage or control group. DOMS was induced with six sets of eight maximal eccentric contractions of the right hamstring, which were followed 2 h later by 20 min of massage or sham massage (control). Peak torque and mood were assessed at 2, 6, 24, and 48 h postexercise. Range of motion (ROM) and intensity and unpleasantness of soreness were assessed at 6, 24, and 48 h postexercise. Neutrophil count was assessed at 6 and 24 h postexercise. Results: A two factor ANOVA (treatment v time) with repeated measures on the second factor showed no significant treatment differences for peak torque, ROM, neutrophils, unpleasantness of soreness, and mood (p > 0.05). The intensity of soreness, however, was significantly lower in the massage group relative to the control group at 48 h postexercise (p < 0.05). Conclusions: Massage administered 2 h after exercise induced muscle injury did not improve hamstring function but did reduce the intensity of soreness 48 h after muscle insult.

To determine the effects of active recovery (AR) from bench press exercise, 15 untrained men and women completed four sets of maximum repetition bench presses at 65% 1-RM under two conditions: an AR consisting of riding a bicycle ergometer at 45% peak [latin capital V with dot above]O2, and passive recovery consisting of lying quietly on a bench. Time between sets was 2 min and the repetition rate during the sets was fixed at 1 rep per 5 sec for both conditions. Subjects in the AR condition recovered more rapidly between sets and had a larger increase in isometric force across the recovery periods. Although there was a significant baseline to postexercise increase in blood lactate, little difference was seen between conditions. Lack of lactate difference may have resulted from greater lactate production (more repetitions were completed so presumably more lactate was generated) but offset by greater removal of lactate in the AR. The results suggest that recovery following fatiguing bench press sets at 65% 1-RM is enhanced by exercising at 45% peak [latin capital V with dot above]O2.

The purpose of this study was to determine the effect of petrassage massage immediately post and 24 hrs postexercise on delayed onset muscle soreness (DOMS), and to measure extremity volumes to determine whether petrassage altered the inflammatory response to eccentric exercise. Thirty-one subjects were randomly assigned to either a petrassage (Mass), stretch (Str), or control group. All underwent an eccentric exercise bout at a workload equal to 100% of their body weight. Mass received petrassage for 10 min on the left calf immediately post and at 24 hrs postexercise. Str performed light stretching exercises preexercise to control for expectancy. Control subjects received no treatment. Plasma creatine phosphokinase (CK) levels and leg volumes were determined preexercise and at 24 and 48 hrs post. Subjects rated their calf DOMS on a 0- to 6-point scale at the end of exercise and at 24 and 48 hrs post. There were no differences in soreness levels between right and left legs or between treatment groups over the 48-hr period. Lower leg volumes at 24 and 48 hrs in all groups showed no change from postexercise. It appears that petrassage does not prevent or attenuate DOMS.

This study was designed to quantify decrease in muscle function that occur during peak periods of delayed onset muscle soreness (DOMS) resulting from eccentric biased exercise. Ten subjects performed fatiguing eccentric exercise utilizing the elbow flexor muscles of one arm, the experimental arm. The other arm served as the control arm. Pre-exercise, 24 and 48 hours post-exercise measurements of soreness, and elbow extension range of motion (ROM) were obtained. Maximal extension forces of both arms were determined prior to exercise and 48 hours post-exercise. Marked perception of soreness in the experimental arm was accompanied by a statistically significant (p<0.01) decrease of ROM and isokinetic strength. The experimental arm exhibited a 16-degree decrease in ROM at 24 hours and a 28-degree decrease at 48 hours. Similarly, peak torque was reduced by 10.6, 7.1 and 4.7 Nm in the experimental arm at the respective angular velocities of 60, 180 and 240 degrees at 48 hours. Because of the marked decrease in ROM and peak torque that occurred following fatiguing eccentric exercise, it was suggested that a reduction in the training regimen be considered during the first few days following eccentric exercise when DOMS is the greatest and isokinetic strength is altered.

The aim of this study was to assess the relationship between power output, lactate, skin temperature, and quadriceps muscle activity during brief repeated exercise with increasing intensity. Eighteen regional level soccer players (age 24.5 ± 3.8 years) were selected after a test of maximal exercise capacity to participate in 2 force velocity (Fv) exercise tests separated by 3 days. The tests were done to examine the reliability of variables measured in the selected subjects during this type of task. During each Fv exercise test, data on power output, heart rate (HR), skin temperature, blood lactate accumulation, the root mean square (RMS), and the mean power frequency (MPF) of the surface electromyography of the superficial quadriceps muscle were collected. Results showed a significant correlation between power output and HR, skin temperature, blood lactate accumulation, and RMS. However, no association was observed with MPF that informs on the level of fatigue and power output. Thus, the result of this study may suggest that the Fv exercise test is not a fatigability test.

This study investigated the hypothesis that a bout of light concentric exercise (LCE) would alleviate delayed-onset muscle soreness (DOMS) and enhance recovery from muscle damage. Fourteen subjects performed two bouts of 60 maximal eccentric actions of the elbow flexors (Max-ECC) separated by 2-4 weeks. One arm performed LCE (600 elbow flexion and extension actions with minimal force generation) 1, 2, 3, and 4 d after Max-ECC; the contralateral (control) arm performed only Max-ECC. Changes in maximal isometric and isokinetic strength, range of motion (ROM), upper arm circumference, and muscle soreness and tenderness were assessed before and immediately after LCE bouts. Changes in these measures and plasma creatine kinase (CK) activity for 7 d after Max-ECC were compared between the control and LCE arms using 2-way repeated measures analysis of variance (ANOVA). Significant (p < 0.05) decreases in muscle soreness (~40%) and tenderness (~40%) were evident immediately after LCE, which also resulted in small but significant decreases in strength (~15%) and increases in ROM (~5°). No significant differences in the changes in the measures following Max-ECC were observed between the arms. These results suggest that LCE has a temporary analgesic effect on DOMS, but no effect on recovery from muscle damage.Key words: muscle soreness, muscle tenderness, muscle strength, range of motion, creatine kinase.
