人体生物节律理论与运动能力初探

A Study on the Relationship Between Biorhythms and Sports Performance

根据生物节律（P．S．I）理论，采用文献资料和体育统计方法，对奥运明星和我国优秀运动员的生物节律进行研究结果表明：人体的体力、情绪和智力的周期性变化对运动能力产生影响，且对不同运动项目的影响程度具有专门性，证明P．S．I理论与运动训练和比赛成绩有密切关系，在体育运动实践中P．S．I．理论具有一定的应用价值，但随着研究的深入发展，P．S．I．理论尚需进一步修正，完善和提高。

According to P. S. I. theory, a study is conducted on the relationship between P. S. I. and sports performance through literature study and sports statistical method. The result indicates that periodic change of an athelets's strength, spirit and intelligence have an influence on his performance and the effect is event-related. Therefore P.S.I. theory is of great value to sports training. But with the deepening study of this subject, P.S.I. theoryremains to be further revised, improved and perfected.
