| Abstract: | In this research,the systematically trained athletes of football and skating are selected as research subjects.By means of measuring the cross-sectional area and force of knee joints＇flexors and extensors,the authors study the skeletal muscle＇s morpho-logical and contractive characteristics as well as the inner relationship between morphology and force of the muscles,providing the theoretical leading for estimating the training level and chosing athletes scientifically,etc. |
