Adult bone marrow-derived cells (BMDC) are shown to contribute to muscle tissue in a step-wise biological progression. Following irradiation-induced damage, transplanted GFP-labeled BMDC become satellite cells: membrane-ensheathed mononucleate muscle stem cells. Following a subsequent exercise-induced damage, GFP-labeled multinucleate myofibers are detected. Isolated GFP-labeled satellite cells...

Background It has been suggested that carbohydrate-protein based multi-ingredient supplements may attenuate exercise induced muscle damage (EIMD) and immunosuppression. This study investigates the effects of a commercially available carbohydrate-protein supplement (MTN) enriched with L-glutamine, L-carnitine-L-tartrate compared to carbohydrate alone (CHO) or placebo (PL), on sprint performance,...

The purpose of this paper is to outline muscle damage and oxidative stress responses high intensity exercise protocols. information provided will be important for athletes, coaches, the general population provide related mechanisms consequences performance

Purpose: Proprioception is a part of the somatosensory system responsible for sending information to the central nervous system to monitor the status of various body parts relative to each another. One of the main causes of impaired proprioception is fatigue. In the following study, the effects of fatigue on quadriceps muscle and hence on knee proprioception in healthy subjects was studied.&nbs...

Ginger possesses analgesic and pharmacological properties mimicking non-steroidal antiinflammatory drugs. We aimed to determine if ginger supplementation is efficacious for attenuating muscle damage and delayed onset muscle soreness (DOMS) following high-intensity resistance exercise. Following a 5-day supplementation period of placebo or 4 g ginger (randomized groups), 20 non-weight trained pa...

1. Duchenne muscular dystrophy (DMD) is a lethal, degenerative muscle disease caused by a genetic mutation that leads to the complete absence of the cytoskeletal protein dystrophin in muscle fibres. 2. The present review provides an overview of some of the physiological pathways that may contribute to muscle damage and degeneration in DMD, based primarily on experimental findings in the mdx mou...

Background: Rugby union players can take several days to fully recover from competition. Muscle damage induced during the match has a major role in player recovery; however the specific characteristics of match play that predict post-match muscle damage remains unclear. We examined the relationships between a marker of muscle damage and performance characteristics associated with physical conta...

Exercise-induced muscle damage (EIMD) occurs primarily from the performance of unaccustomed exercise, and its severity is modulated by the type, intensity, and duration of training. Although concentric and isometric actions contribute to EIMD, the greatest damage to muscle tissue is seen with eccentric exercise, where muscles are forcibly lengthened. Damage can be specific to just a few macromo...

Background: The purpose of the present investigation was to study the possible differences between young and elderly individuals regarding muscle damage, position sense, and oxidative stress biomarkers in response to resistance eccentric-biased exercise. Methods: Ten young and 10 elderly individuals performed a bout of resistance exercise (i.e., squat exercise). Muscle damage indices (i.e., iso...
