摘　　要：目的:研究动态瑞士球练习对游泳运动员躯干核心区4个主要肌群的刺激强度,旨在为游泳运动员的瑞士球练习提供一定的参考依据。方法:选择10名男子一级游泳运动员为受试对象。利用BIOPAC-MP150多导生理仪,对受试者在24种动态瑞士球练习中的腹直肌、腹外斜肌、竖脊肌和多裂肌这4个肌群进行表面肌电测试,计算各受试肌群的AEMG值。通过聚类将24种瑞士球练习分为4类,在平面直角坐标图上绘制各类瑞士球练习中各肌群的AEMG值图形并计算图形面积。结果:第1类是以腹外斜肌和竖脊肌为主导发力的练习;第2类是以竖脊肌主导发力的练习;第3类是以腹直肌和腹外斜肌为主导发力的练习;第4类是以竖脊肌和多裂肌为主导发力的练习。结论:24种瑞士球练习对躯干核心区4个肌群的AEMG值分别都在10%～50%左右,均属于中、低负荷强度的练习;运用坐标图面积计算法可以计算出瑞士球动作对躯干肌群的总刺激强度,能够简单并直观地表现出各动作对躯干肌群的刺激情况;与水中技术动作联系的紧密性以及无固定支撑是瑞士球练习应用于游泳运动的核心特征,运动员与教练员可以遵从训练原则,通过多种手段将瑞士球练习合理应用于游泳专项训练中。The study is to test and analysis the surface electromyography in 24style of dynamic Swiss ball exercises, for study the stimulation intensity of four maior trunk muscle of swim ruing athlete in Swiss ball practice. The expectation of the study is to provide some valuable reference to swimming athlete＇s Swiss ball exercises. 10 healthy National llevel swimming athletes volunteered to participate in the study. Use BIOPACMP150 physical instrument to test the subjects＂ abdominal muscle, obliquus externus abdominis muscle, erector spinae muscles and Multifidus muscle in 24style Swiss ball exercises, calculating the muscle AEMG value of subjects. Through the cluster, 24style Swiss ball exercises are divided into four types, draw on each type of Swiss ball exercises in the graphics in plane right angle coordinate by using the AEMG data, the results is that the first category of exercises is turn to the little more obliquus externus abdominis muscle and erector spinae muscles leading with the power of exercises; The second category of exercises is turn to the little more erector spinae muscles leading with the power of exercises; The third category of exercises is turn to the abdominal muscle and obliquus externus abdominis muscle as the major leading with the power of exercises; The fourth category of exercises is turn to the erector spinae muscles and Mujtifidus muscle as the major leading with the power of exercises. The Conclusions is that 24style Swiss ball exercises to the trunk＇s core four muscle group of AEMG value are in 10%- 50%, all belong to a low load strength of practice; using the method of plane right angle coordinate to figure area computation can calculate the stimulus strength value of trunk muscle group of Swiss ball exer cises, can simply and intuitively showing the trunk muscle stimulus values on Swiss ball exerci ses. The coaches and athletes can accord the graphics area selecting the appropriate value prac tice used in training The key characteristic of Swiss ball used in swimming, is
