skeletal muscle may develop adaptive chaperone and enhancementdefense system through daily exercisestimulation. the present study investigated resistance and exhaustion training alters the expression of chaperoneproteins. these proteins function to maintain homeostasis, facilitate repair from injury and provide protection. exercise-induced production of hsps in skeletal muscle and peripheral le...

QUESTION Does eccentric muscle training of hamstring muscles reduce the rate of hamstring injuries in male soccer players? DESIGN Cluster randomised, controlled trial with concealed allocation. SETTING The 5 top men's soccer divisions in Denmark. PARTICIPANTS First team squad soccer players from teams in the top 5 national soccer divisions were included. Players who joined a team after th...

conclusions the study findings indicate that short-term exercises had no significant effect on the ratio of vmo to vl muscle fiber angles in patients with pfps. results there were no significant differences in the muscle strength and fiber angle of the vmo, vl oblique and longus muscles after training between the control and experimental groups (p > 0.05). patients and methods thirty-five subje...

Polymyositis and dermatomyositis are orphan, chronic skeletal muscle disorders characterized by weakness, infiltrations by mononuclear inflammatory cells, and fibrosis. Until recently, patients were advised to refrain from physical activity because of fears of exacerbation of muscle inflammation. However, recent studies have shown that moderate exercise training in combination with immunosuppre...

there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...

introduction: the use of antioxidants before high-intensity training, which leads to the release of free radicals and muscle injuries, can result in reduced damage during exercise. accordingly, in this study, we aimed to evaluate the effect of selenium supplement intake on oxidative stress, following exhaustive aerobic exercise among young physically-active females. methods: in this quasi-exper...
