摘　　要：运用专家访谈、肌电测量和数理统计等研究方法,以12名体育教育、运动系学生为研究对象,对其单杠屈伸上动作技术的训练学与肌电学特征进行研究,结果表明:屈伸上整个动作的完成与股直肌、腹直肌的肌肉力量关系很大,对动作技术的完成有着重要的影响;不同群体学生在动作完成过程中表现出不同的用力状态,顺利完成动作的群体肌肉用力相对更为集中、经济,节省体力,而勉强完成动作的群体所表现的用力却是杂乱无章,竖脊肌的用力过多等状态,对动作的完成有阻碍;因个体和技术特点的不同,在完成动作时各肌群的用力有一定的差异。建议在重视各阶段主要肌肉用力的同时,不能忽视相关肌群对动作完成的影响。By using the methods of experts’ interview,muscle electric measurement and mathematical statistics,this paper studies the electromyography characteristics of fles up movement skills on horizontal bar.The object of the study is 12 students from department of sports education,the result shows that the movement of flex up has an impact on the completion of the whole action and this movement depends on the strength of femoris muscle and rectus muscle;the movements of different groups of students showed different conditions of using strength in the process,moreover,the muscles groups which successfully complete the action were more concentrated and saved more energy,while the group of those that barely completes the action is disorganized with other status that the erector spine muscles is too hard,which hinders the completion of the action;as individual technical characteristics are different,there are certain differences in each muscle group upon completion of the action.It’s suggested that when we pay much attentions to major muscle force at all stages,the relevant muscle group＇s influence on the action to complete can’t be ignored.
