Abstract:

BACKGROUND: Apoptotic process can be activated by evoked movement and cause cell death.
OBJECTIVE: To analyze the effects of exercise training on apoptosis in different tissues, to discuss the relationship of exercise fatigue, sports injuries, athletic heart remodeling, exercise-induced minor myocardial injury, exercise-induced immunosuppression and apoptosis in different tissues.
METHODS: An online search of Medline database was performed using key word of “apoptosis” for articles published from January 1990 to May 2010. Articles on relations between exercise training and apoptosis were included. Meanwhile, another online search of Ginii database was performed using key words of “アポトーシス，運動” for relevant articles published from January 2000 to June 2010. And a third online search of China National Knowledge Infrastructure database was performed using key words of “apoptosis, exercise training, skeletal muscle, myocardium, lymphocytes, liver and kidney cells” in Chinese for relevant articles published from January 2000 to May 2010.
RESULTS AND CONCLUSION: Single exercise and systematic exercise training both affect apoptosis in skeletal muscle, myocardium, lymphocytes, liver cells and kidney cells. Apoptosis level increases with the increasing of exercise intensity. These findings indicate that apoptosis is closely related to exercise-induced skeletal muscle micro-injury, athletic heart remodeling and exercise-induced minor myocardial injury.
