THE KEY RESEARCH OF SPORTS IN MAINTAINING HUMAN HEALTH

ABSTRACT Introduction One of the evaluation factors of human health is bone health, and an evaluation index of bone health is osteoporosis. Sports are an effective way to improve the human body. Objective The paper discusses the effects of different exercise intensities on human bone health. Methods The thesis selected 51 female college students, designed different exercise intensities of fitness running intervention programs, and conducted a 12-month exercise intervention. We divide female college students into three groups. The subjects’ bone mineral density (BMD), serum alkaline phosphatase (ALP), and serum osteocalcin (BGP) were tested before and after the experiment. Results The differences in femoral BMD, serum ALP, serum BGP, and lumbar spine BMD of the three groups of volunteers were significant (P<0.05), while the differences in ulna and radius BMD were not significant. Conclusions Sports can promote human bone health. At the same time, the effect of fitness running on human BMD is site-specific. Level of evidence II; Therapeutic studies - investigation of treatment results.
