(Department of Physical Education,Hunan Institute of Engineering,Xiangtan 411101,China) Abstract: On the basis of the real biodynamic figures of the excellent 100m athlete,one can determine the power such as potential energy、power、resistance and the proportion used in each power with the method of divided,summarize the reason of power efficiency of each step,the power efficiency of each division,and the law of the distrbution and the effective power.Large steps may save resistance power up the ability to control the speed may help the athlete to use the energy rational.The training of using the limited output power will reduce the liquid frequency and the range of the limited speed during the exercise.The opinions above will be detailed in it. Key words:momentum loss; power distrbution; artificial analysis;100 m short-distance runner |
