摘　　要：目的:对专业大学生的网球正手击球技术进行运动学特征研究,分析不同水平的学生在正手击球技术上的差异。方法:选取12名网球专业男性大学生分为一级组6人,二级组6人,应用MCU400运动捕捉系统对学生的髋连线、肩连线、拍头连线、分离角进行数据采集。结果:(1)后摆技术时刻,肩连线、髋连线二级组小于一级组,屈肘角、分离角、球拍转动角二级组大于一级组均不具显著性差异(p>0.05);(2)击球肩速度、肩连线、髋连线、伸肘速度、躯干转动、髋转动6个指标均为二级组小于一级组,其中只有肩速度两组存在非常显著性差异(P<0.01),其他5个指标均无显著性差异(P>0.05)。屈肘角度、伸腕角度、球拍转动角、后腿伸展4个指标均为二级组大于一级组,但均无显著性差异(P>0.05)。(3)随揖阶段肩连线二级组大于一级组,髋连线二级组小于一级组,均不具显著性差异(P>0.05)。Objective:to analyze the kinematic characteristics of College Students’forehand batting skills,and study the differences of fore hand hitting skills among different levels of students.Methods:12 male college students majoring in tennis were selected and divided into the first-level group(6)and the second-level group(6).MCU400 motion capture system was used to collect the data of students’hip line,shoulder line,racquet head line and separation angle.Results:(1)In the racquet leading stage,the shoulder line and elbow flexion Angle ii group were lower than the first group,and the hip line,separation Angle and racket rotation Angle II group were higher than the first group(P>0.05).(2)the swing phase:secondary shoulder speed is less than level group(p≤0.01)or less,shoulder,hip Angle attachment,attachment and elbow speed secondary group is less than level group(p>0.05),and elbow flexion,wrist Angle,the racket Angle of rotation,hind legs stretched secondary is greater than the primarygroup(p>0.05),trunk rotation,and hip rotation secondary group is less than level group(p>0.05);The second class shoulder line was larger than the first group(P>0.05),and the second class hip line was smaller than the first group(P>0.05).
