Abstract:

BACKGROUND: Human bone mineral density is affected by various factors, including exercise.
OBJECTIVE: To summarize the effects of exercise on bone mineral density of different people and to provide the theory guide for scientific exercise.
METHODS: Articles in accordance with inclusion and exclusion criteria were retrieved from CNKI and Medline database from 1985 to 2009. After data evaluation, in total 45 articles were included in the final analysis. The involved articles were summarized based on effects of exercise on bone mineral density of children, juveniles, middle-aged people and old people.
RESULTS AND CONCLUSION: To teenagers, the mass of bone mineral density had important effects on peak value and adult osteoporosis. To middle-aged people, the decreased estrogen level would affect the role of exercise on bone mass. Aerobic exercise could maintain bone mineral density in a normal level and delay the senile osteoporosis. Exercise affected bone mineral density of different people. Various types of exercise have different effects and the loading exercise have more benefits than unloading exercise; and the effects of long-term exercise should be paid more attention.
