卜范芳是我国女子400m跑冠军，多年来一直将模拟跑道训练作为一种创新的训练方法，对于提高其速度耐力水平有着非常显著的效果。本研究目的旨在通过运动学测试和肌电测试，比较卜范芳模拟跑道跑和场地跑技术结构和肌肉用力结构的差异，从而客观地评价这一训练方法的优劣。运动学测试表明，模拟跑道跑和场地跑两种技术比较，蹬地腿的蹬离角、摆动腿的最小折叠膝角、最大髋角、腾空高度和时间都存在较大差异。肌电测试表明，下肢8块主要肌肉在两种跑的技术中其贡献率也存在明显的差异。因此认为，如果长期进行模拟跑道训练，将会导致运动员技术动作的改变和肌肉用力的不协调；模拟跑道训练作为提高速度耐力的训练手段比例不宜太大，最好在运动强度训练阶段采用。

Ms Pu Fan - fang, a Chinese national championship, has been training on simulated treadmill for 4 years to improve her ablility of veloctity endurance. The purpose of the present study was to compare the changes of her movement sturetures in ground and treadmill running. EMG and kinematical analysis were used in the test. The kinematical data rsults show that significant differences were noted between the two conditions for the take - off angle, minimum knee angle of swing leg, maximum hip angle, coar high and soar time. the EMG result revealed that the significant differences of EMG distribution of eight muscles existed in the two conditions. According to the testing results, it should be considered that more treadmill training could influence her moveumt sturcture altough it is a good method to improve velocity endurance. We suggest that it be better to adopt it in the phase of intensity training.
