- To investigate the the body shape strength and kinematics that effects sprint expert performance 17 healthy male sprinters were measured 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 theory the 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 100m performance ; ( 3 ) the biggest shoulder extension joint , swing rage of shoulder and the biggest elbow joint extension effect 100m performance
受试者为17名男子一、二级短跑运动员。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 -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 (慢速) 、 240 s (中速)和360 s (快速)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 (快速)及120 s下测试下肢3关节等速向心及离心肌收缩肌力。
