The aim of this study was to compare the effects of various recovery techniques on muscle tissue after eccentric exercise-induced muscle fatigue (EIMF). Forty subjects (24.3 ± 2.6 years; 77.45 ± 8.3 kg; 177.0 ± 6.4 cm; 24.66 ± 1.6 kg∙m−2) were randomly assigned to one of the following groups: manual therapy (n =10, MT), mechanical vibration (n = 10, MV), percussion therapy (n = 10, PT) or foam roller (n = 10, FR). The contraction time (Tc) and the radial displacement (Dm) of the gastrocnemius was evaluated through tensiomyography (TMG). The application of the different techniques had positive effects for Tc and Dm in the treated leg compared to the untreated leg (F = 50.01, p < 0.01, η2p = 0.58 and F = 27.58, p < 0.01, η2p = 0.43, respectively) and for the interaction of the factors (Time x Leg x Therapy: F = 5.76, p < 0.01, η2p = 0.32 and F = 5.93, p < 0.01, η2p = 0.33, respectively). The results of the various methods used were similar: Tc (F = 0.17, p = 0.917; η2p = 0.01) and Dm (F = 3.30, p = 0.031, η2p = 0.22). PT interventions show potential for restoring muscle compliance and reducing stiffness, similar to MT and possibly more effective (cost-time relationship) compared to MV or FR.

PURPOSE:The present study aimed to investigate the effects of transdermal application of methylsulfonylmethane (MSM) on muscle damage and recovery following eccentric exercise in young men.METHODS: Eleven college-aged men without any cardiovascular or orthopedic disorders underwent two sessions consisting of a control session (CS) and an experimental session (ES) in a random order with at least 2 weeks of wash-out between the sessions. The participants performed 30 maximal eccentric exercises involving their non-dominant elbow flexors in each session. Circumference, muscle soreness, range of motion, maximal voluntary isometric contraction (MVIC), and muscular echo intensity (EI) were measured to evaluate the changes in the level of exercise-induced muscle damage (EIMD). All measurements were performed at 24, 48, 72, and 96 hours after exercise and also immediately before and after exercise.RESULTS:Transdermal application of MSM in ES attenuated muscle swelling and decreased MVIC after eccentric exercise when compared with CS. Muscle soreness and EI tended to increase less rapidly and decrease more rapidly in ES than in CS.CONCLUSIONS: Transdermal application of MSM may induce relatively positive effects on EIMD and recovery following eccentric exercise when compared with the treatment that has been widely used previously.

Although several kinds of amino acids (AAs) are known to affect physiological actions during exercise, little is known about the combined effects of a mixture of several AAs on fatigue during exercise. The aim of the present study was to investigate the effect of an AA mixture supplement containing arginine, valine, and serine on exercise-induced fatigue in healthy volunteers. These AAs were selected because they were expected to reduce fatigue during exercise by acting the positive effects synergistically. A randomized, double-blinded, placebo-controlled crossover trial was conducted. Thirty-nine males ingested an AA mixture containing 3600 mg of arginine, 2200 mg of valine, and 200 mg of serine or a placebo each day for 14 days. On the 14th day, the participants completed an exercise trial on a cycle ergometer at 50% of VO2max for 120 min. After the two-week washout period, the participants repeated the same trial with the other test sample. The participant’s feeling of fatigue based on a visual analog scale (VAS) and a rating of perceived exertion (RPE), as well as blood and physical parameters were evaluated. The feeling of fatigue based on VAS and RPE were significantly improved in AA compared to those in placebo. In the blood analysis, the increase in serum total ketone bodies during exercise and plasma tryptophan/branched-chain amino acids were significantly lower in AA than those in placebo. The present study demonstrated that supplementation with an AA mixture containing arginine, valine, and serine reduced the feeling of fatigue during exercise. The AA mixture also changed several blood parameters, which may contribute to the anti-fatigue effect.

Training Background

It has been proposed that exercise-induced oxidative stress and adaptations are dependent on training status. In this study, we examined the effects of training background on free radical generation and adaptations after eccentric exercise. Forty volunteers were divided into two groups (trained and untrained) and were asked to perform eccentric exercise. Then, their blood samples were collected pre, 24, 48, and 72 hours postexercise. Biomarkers indicating oxidative damage and the antioxidant profiles of the participants were measured in plasma and erythrocyte lysate both spectrophotometrically and chromatographically. The results revealed that the untrained group depicted more severe oxidative damage (protein carbonyls, malondialdehyde), weaker antioxidant status (reduced glutathione, static and capacity oxidation-reduction potential), and weaker radical-scavenging activity (superoxide radical scavenging and reducing power) compared to the trained participants. Our findings show that trained individuals are less susceptible to oxidative damage and suggest that generalized nutritional recommendations regarding recovery after exercise should be avoided.

In order to provide scientific proof to anion functional fabrics application research in textile domain, in this article, anion functional fabrics were prepared, the anion generating capacity was determined and the effect of anion fabrics and mice BLA after exercise were first studied. The anion generating capacity shows that: due to the adding of anion function powders to function fabrics, the anion amount released by function fabrics is apparently higher than common fabrics. Washing can not significantly reduce the anion amount of function fabrics releasing. These can indicate that the function fabrics can release anion stable and lasting. The determination of mice’s BLA after swimming showed that Compared to common fabrics, functional fabrics have significant difference (P<0.05). The anions of functional fabrics releasing can reduce animals BLA after exercise and help to eliminate exercise-induced muscle fatigue.
