对男子400m个人混合泳运动员各分段成绩研究发现：第1段游速最快,第6段游速最慢,第4段出现途中游加速即＂1加＂现象,这是运动员在第1段快速加速后身体适应性调整的必然结果。主成分提供的第23、段、第4段和第8段信息是全程速度变化研究的重点,第8段冲刺能力受前7段制约,因此,体能研究重点更多是对第23、段和第4段分配合理性的分析,第1段的游速对全程体能分配具有至关重要的作用。

According to the study of each athlete＇s piecewise statistics in Men＇s 400m Individual Medley,this paper finds that the first distance is the fastest,the 6th is the slowest and at the middle of the 4th distance raises a phenomenon called ＂1 accelerate＂,which is an inevitable result of body adaptability adjustment when an athlete accelerates at the first distance.They are focal points of studying the whole distance speed variation that information about the 8th,2th,3th,and 4th distance which is offered by principal components.The sprint ability of the 8th distance is limited by the former seven distances.Therefore,the key of physical research is analysis of distribution rationality in the 2th,3th and 4th distances.What＇s more,speed of the first distance contributes a lot to the physical distribution of the whole distance.
