摘　　要：了解不同身体形态指标人群做悬垂举腿动作所需机械能的差异,为训练和改进评分提供参考。根据成年人身体惯性参数,基于能量转化理论,运用Simulink软件对不同身体形态指标人群做悬垂举腿动作仿真,并对所需的机械能进行可视化分析。身体质量或者身高一定时,悬垂举腿所需的机械能随着身高或者身体质量的增加而增大。单位身高或者体质量,机械能增量随着体质量或者身高的增加而增大。女子做悬垂举腿所需的机械能大于相同身高和体质量的男子。The purpose was to understand the mechanical energy of people with different body morphology indexes when they hang and raise legs.The results provide a reference for training and improving the grading methods.The mechanical energy of people with different body morphology indexes was visualized by Simulink.When people of a certain weight(height)hang and raise legs,the mechanical energy increases with the increase of height(weight).The increase in mechanical energy is in direct proportion to height(weight).Women produce more mechanical energy than men of the same height and weight when they hang and raise legs.

关 键 词：悬垂举腿 身体形态指数 机械能
