Introduction: The aim of the present work was to perform a meta-analysis evaluating the impact of recovery techniques on delayed onset muscle soreness (DOMS), perceived fatigue, muscle damage, and inflammatory markers after physical exercise. Method: Three databases including PubMed, Embase , and Web-of-Science were searched using the following terms: ("recovery" or "active recovery" or "cooling" or "massage" or "compression garment" or "electrostimulation" or "stretching" or "immersion" or "cryotherapy") and ("DOMS" or "perceived fatigue" or "CK" or "CRP" or "IL-6") and ("after exercise" or "post-exercise") for randomized controlled trials, crossover trials, and repeated-measure studies...

Running economy (RE) is impaired following unaccustomed eccentric-biased exercises that induce muscle damage. It is also known that muscle damage is reduced when maximal voluntary isometric contractions (MVIC) are performed at a long muscle length 2-4 days prior to maximal eccentric exercise with the same muscle, a phenomenon that can be described as isometric pre-conditioning (IPC). We tested the hypothesis that IPC could attenuate muscle damage and changes in RE following downhill running. Thirty untrained men were randomly assigned into experimental or control groups and ran downhill on a treadmill (-15%) for 30 min...

Previous studies addressed the antioxidant and anti-inflammatory role of compounds from green tea in different human tissues. Positive antioxidant and anti-inflammatory effects were described for brain tissues. Whether similar effects are observed in the skeletal muscle, green tea supplementation could be a strategy to reduce delayed onset muscle soreness resultant of exercise. Here we determine the effect of green tea extract supplementation on exercise-induced muscle soreness, muscle damage and oxidative stress...

Background: Emerging evidence indicates that fruits rich in polyphenols may attenuate exercise-induced muscle damage and associated markers of inflammation and soreness. This study was conducted to determine whether bilberry juice (BJ), which is particularly rich in polyphenols, reduces markers of muscle damage in runners completing a half marathon. Methods: A total of 21 recreationally trained runners (age 30.9 ± 10.4 y; mass 71.6 ± 11.0 kg; M = 16; F = 5) were recruited to a single blind, randomised, placebo-controlled, parallel study...

Long-term cigarette smoking (LTCS) represents an important risk factor for cardiac infarction and stroke and the central risk factor for the development of a bronchial carcinoma, smoking-associated interstitial lung fibrosis, and chronic obstructive pulmonary disease. The pathophysiologic development of these diseases is suggested to be promoted by chronic and progressive inflammation. Cigarette smoking induces repetitive inflammatory insults followed by a chronic and progressive activation of the immune system...

Lower physical performance is an important risk factor in hypokinetic-related chronic disease, metabolic syndrome, and muscle atrophy. Our previous research demonstrated that Platycodon grandiflorum-derived saponin (PS) protects against eccentric exercise-induced muscle damage and mitochondrial function-related peroxisomal acyl-coenzme A oxidase (ACOX-1) and carnitine palmitoyltransferase (CPT-1) in high-fat diet-induced non-alcoholic steatohepatitis, and it inhibits osteoclast differentiation. However, the effects of PS on physical performance remain unknown...

Strenuous exercise can result in skeletal muscle damage, leading to the systemic mobilization, activation and intramuscular accumulation of blood leukocytes. Eicosanoid metabolites of arachidonic acid (ARA) are potent inflammatory mediators, but whether changes in dietary ARA intake influence exercise-induced inflammation is not known. This study investigated the effect of 4 weeks of dietary supplementation with 1.5 g/day ARA (n=9, 24 {plus minus} 1.5 years) or corn-soy oil placebo (n=10, 26 {plus minus} 1...

BACKGROUND: Growing evidence suggests beta-hydroxy-beta-methylbutyrate's (HMB) positive effects on recovery following exercise-induced muscle damage (EIMD). However, findings vary substantially across studies. OBJECTIVE: A meta-analysis of randomized controlled trials was conducted to assess the effects of HMB supplementation on recovery following EIMD by assessing indirect markers of muscle damage, namely creatine kinase (CK) and lactate dehydrogenase (LDH) serum levels among healthy participants...

AIMS: Muscle damage in Duchenne Muscular Dystrophy (DMD) caused by the lack of dystrophin is strongly linked to inflammation. Heme oxygenase-1 (HO-1; Hmox1) is an anti-inflammatory and cytoprotective enzyme affecting myoblasts differentiation by inhibiting myomirs. The role of HO-1 has not been so far well addressed in DMD. RESULTS: In dystrophin-deficient mdx mice expression of Hmox1 in limb skeletal muscles and diaphragm is higher than in wild-type animals, being consistently elevated from 8 up to 52 weeks, both in myofibres and inflammatory leukocytes...

Background: Skeletal muscle injury activates satellite cells to initiate processes of proliferation, differentiation, and hypertrophy in order to regenerate muscle fibers. The number of microRNAs and their target genes are engaged in satellite cell activation. β-Hydroxy-β-methylbutyrate (HMB) is known to prevent exercise-induced muscle damage. The purpose of this study was to evaluate the effect of HMB on miRNA and relevant target gene expression in differentiating equine satellite cells exposed to H2 O2 ...

BACKGROUND: It is well known that eccentric muscle contractions induce delayed onset muscle soreness (DOMS) and exertional rhabdomyolysis (ERB), both of which are related to high blood levels of muscle damage markers after exercise. Creatine kinase (CK) is, together with some other markers (e.i. myoglobin, α-actin, skeletal troponin), widely used in determination of muscle damage. Moreover, DOMS after eccentric exercise has been shown to be associated with altered blood lactate concentration after subsequent submaximal or maximal cycling exercise...

We aimed to examine the effects of ingestion of different amounts of carbohydrate (CHO) after endurance exercise on neutrophil count, circulating cytokine levels, and the markers of neutrophil activation and muscle damage. Nine participants completed three separate experimental trials consisting of 1 h of cycling exercise at 70% V · O₂ max, followed by ingestion of 1.2 g CHO·kg body mass-1 ·h-1 (HCHO trial), 0.2 g CHO·kg body mass-1 ·h-1 (LCHO trial), or placebo (PLA trial) during the 2 h recovery phase in random order...

We investigated whether low-level laser therapy (LLLT) prior to or post resistance exercise could attenuate muscle damage and inflammation. Female Wistar rats were assigned to non-LLLT or LLLT groups. An 830-nm DMC Laser Photon III was used to irradiate their hind legs with 2J, 4J, and 8J doses. Irradiations were performed prior to or post (4J) resistance exercise bouts. Resistance exercise consisted of four maximum load climbs. The load work during a resistance exercise bout was similar between Control (non-LLLT, 225 ± 10 g), 2J (215 ± 8 g), 4J (210 ± 9 g), and 8J (226 ± 9 g) groups...

This study purpose was to analyze the effect of EIMD in gross efficiency and in aerobic and anaerobic cycling performance. Nine well-trained cyclists (30.8 ± 6.4 years, cycling experience 8.4 ± 5.6 years) visited the laboratory 5 times. During the first visit, they performed a maximal incremental test on a cycle ergometer, to identify VO2max (55.2 ± 4.9 mL.kg.min) and maximum aerobic power (Pmax; 327.0 ± 28.5 watts). During the second visit (control), they cycled 5 minutes at 60% of Pmax, 5 minutes at 70% of Pmax, 5 minutes time-trial, and Wingate test...

Methylene-tetrahydrofolate reductase (MTHFR) and paraoxonase 1 (PON1) gene polymorphisms have been associated with hyperhomocysteinemia and oxidative stress increase, that are established cardiovascular risk factors. Given that intense physical activity may increase the susceptibility to adverse cardiovascular outcomes, here we investigated the effects of MTHFR C677T and A1298C as well as PON1 Q192R gene polymorphisms on cardiovascular risk markers in twenty-eight male water polo elite players. The mean plasma levels of homocysteine (Hcy) and advanced oxidation protein products (AOPP) were above reference limits in resting conditions, and increased after competition...

Given its pivotal role in fatty acid oxidation and energy metabolism, l-carnitine has been investigated as ergogenic aid for enhancing exercise capacity in the healthy athletic population. Early research indicates its beneficial effects on acute physical performance, such as increased maximum oxygen consumption and higher power output. Later studies point to the positive impact of dietary supplementation with l-carnitine on the recovery process after exercise. It is demonstrated that l-carnitine alleviates muscle injury and reduces markers of cellular damage and free radical formation accompanied by attenuation of muscle soreness...

OBJECTIVE: Mechanically overloaded muscle and its subsequent damage are strong stimuli for eliciting acute hormonal changes, while the muscle adaptation which occurs following exercise-induced muscle damage may involve complex hormonal responses before the completion of muscle regeneration. The purpose of this study was to investigate systemic responses of various hormones, as well as secreted proteins that are exercise-regulated and associated with muscle adaptation, for several days after eccentric exercise-induced muscle damage in humans...

PGC1α is a pleiotropic co-factor that affects angiogenesis, mitochondrial biogenesis, and oxidative muscle remodeling via its association with multiple transcription factors, including the master oxidative nuclear receptor ERRγ. To decipher their epistatic relationship, we explored ERRγ gain of function in muscle-specific PGC1α/β double-knockout (PKO) mice. ERRγ-driven transcriptional reprogramming largely rescues muscle damage and improves muscle function in PKO mice, inducing mitochondrial biogenesis, antioxidant defense, angiogenesis, and a glycolytic-to-oxidative fiber-type transformation independent of PGC1α/β...

Previously, we monitored the expression level of the pro-apoptotic proteins caspase-3 and cleaved poly-ADP-ribose polymerase in the skeletal muscle of high-fat diet-induced obese rats in order to assess muscle damage. In this study, we analyzed whether exercise or dietary adjustment was more effective at preventing high-fat diet-induced muscle damage. High-fat diet-induced obese rats were divided into three groups: the high-fat diet (HFD), the combined high-fat diet and exercise (HFD+EXE), and the dietary adjustment (DA) groups...
