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

摘要
引言：骨骼健康是评估人类健康的核心指标之一，骨质疏松症则是评估人体骨骼健康状态的重要维度。运动是改善人体生理机能的有效途径。
研究目的：本研究旨在探讨不同运动强度对人体骨骼健康的影响。
研究方法：本研究选取51名女大学生，设计不同运动强度的健身跑干预方案，并开展为期12个月的运动干预。将受试女大学生分为三组，分别于实验前后检测受试者的骨密度（bone mineral density, BMD）、血清碱性磷酸酶（serum alkaline phosphatase, ALP）及血清骨钙素（serum osteocalcin, BGP）水平。
研究结果：三组志愿者的股骨骨密度、血清ALP、血清BGP及腰椎骨密度均存在显著差异（P
