NBA与CBA比赛跳跃步法的对比分析

通过录像分析了NBA与CBA各8场比赛,对比CBA与NBA比赛中各个位置队员使用各种跳跃步法的差异。将跳跃步法按原地起跳、一步助跑起跳、两步以上单脚起跳、两步以上双脚起跳、后撤步起跳、连续起跳、横向移动急停起跳等7种方式进行了归类和统计。结果发现CBA队员比NBA队员更多地采用了原地起跳,而在一步助跑起跳与两步以上助跑双脚起跳的使用频率上比NBA低。相差最大的是横向移动急停起跳,NBA的控球后卫、得分后卫、小前锋使用该步法的频率分别是CBA相同队员的1.6倍、2.1倍、3.9倍。提示：CBA队员应该增加运动中起跳的次数,尤其要加强对横向移动急停起跳的训练与应用。同时要加强对横向移动急停起跳的生物力学研究,为提高训练效果、预防损伤、研发符合篮球运动特点的篮球鞋提供理论依据。

Comparison of Jumping Footwork in NBA and CBA Matches

Through video analysis,the author analyzed 8 matches each in NBA and CBA so as to compare the difference of the different jumping footwork of of the different position players in CBA and NBA matches.The jumping footwork is classified into 7 types,i.e.,standing jump,one-step jump,over two steps one-foot jump,over two steps two-feet jump,backward step jump,continuous jump and lateral movement abrupt stop jump.The result shows that compared to NBA players,more CBA players use standing jump and the frequency of using one-step jump and over two steps two-feet jump is lower.Great different can be found in lateral movement abrupt stop jump.The frequency of using this footwork by NBA’s point guard,shooting guard and small forward is 1.6 times,2.1 times and 3.9 times separately than the CBA players.This suggests that CBA players should increase jumping times in movement and strengthen the training and application of lateral movement abrupt stop jumping.At the same time,more attention should be paid to the biomechanical study of lateral movement abrupt stop jump so as to improve training efficiency,prevent injury and provide theoretical reference for developing basketball shoes that meet the requirements of the sport.
