To investigate the the body shape strength and kinematics thateffects sprint expert performance 17 healthy male sprinters weremeasured using SongxiaM9000 high speed vidicon in the field; body shape of sprint athlete were tested by steel rule; Meanwhile shoulder were tested at 60, 240and360 deg/sec velocities ; lower limb were tested at 60, 240 deg/sec velocitues using Biodex-II tesing and rehabilitation system in the laboratory This research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theoryThe result show that (1) The results of correlation indicate that 100M performance related to the shoulder fast flexion torque and hip flexion/extension torque^ ankle fast dorsiflexion torque ;(2) The upper arm relaxing enclose and lower limbs length effect 100Mperformance;(3) The biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100M performance.

使用松下M9000高速摄像机对100米跑动过程中的运动员进行录像，同时测试短跑运动员100米成绩，利用爱捷录像分析系统获取运动学参数；用人体测量尺测试短跑运动员的肢体围度；同时采用Biodex-Ⅱ型等动测力及康复统，测试运动员上肢肩关节及下肢髋、膝、踝3个关节的等速屈伸肌力。在角速度60°／s、240°／s和360°s下测试肩关节等动向心收缩肌力；在角速度60°／s9慢速和240°／s及120°／s下测试下肢3关节等速向心及离心肌收缩肌力。分析肢体围度、各关节肌肉力量和运动学参数与100 影响河北省二级以上短跑运动员专项成绩的因素。一身体形态、力量素质和运动学参数米成绩的内在联系，为合理制订短跑力量训练和完善短跑理论提供理论依据。结果表明；肩带肌群肌力矩确实与100米成绩呈显著高度相关，同时髓关节屈伸力矩比、踝关节背屈力矩与100米跑成绩呈显著中度相关，可能《是影响100米的因素之一。（2）上臂紧张围、上臂放松围与100米跑成绩呈显。著中度相关；最大肩关节伸角、肩关节摆动幅度和最大肘关节伸角与 100 米成绩呈显著中高度相关。
