贴扎对男子篮球后卫运动员踝关节限制作用的时效性研究

The Chronergy of Ankle Taping in Basketball Players

目的：研究踝关节贴扎限制作用的变化趋势，为踝关节贴扎在篮球运动中的实际应用提供依据。方法：选取训练时间均在5年以上的男子篮球后卫运动员10名，二级运动员。以中国国家男子篮球队在北京奥运会上6场比赛统计强度的80％作为实际实验强度，采用图像标记法，测量踝关节贴扎前、后以及每运动10分钟后的踝关节主动和被动背屈、跖屈、内翻、外翻活动度，确定踝关节贴扎失效时间点。结果：贴扎后踝关节活动度（ROM）与贴扎前比较减小（P〈0．01）；随着运动时间延长，踝关节ROM呈上升趋势；在实验强度下，贴扎后运动30--40分钟后，踝关节ROM与贴扎前比较无显著差异（P〉0．05）。结论：踝关节贴扎对踝关节具有保护作用；踝关节贴扎失效的时间范围在运动后30～40分钟，应在半场休息时为运动员踝关节进行二次贴扎，以持续有效地预防踝关节损伤的发生。

Objective This study aims to investigate the effective duration of ankle tapping in order to provide theoretic basis for practical use. Methods We adopt image marking method for measuring ankle passive and active range of motion （ROM）,including dorsiflexion,plantar flexion,inversion and eversion of the foot in 10 guards （training duration 〉5 years） from a basketball team before and after tapping,as well as every 10 minutes of playing. Exercise intensity is determined in accordance to 80% intensity （average of six matches） of China National Men Basketball Team performed at Beijing Olympic Games. Results Data show that ankle tapping restricts ankle ROM from the beginning of playing （P〈0.01）, and the restriction becomes weakened with prolonging of the playing. The restriction of ROM disappears after 30 to 40 minutes of playing （P〉0.05）. Conclusion The protective effect of ankle taping is weakening with the prolongation of playing, and thus it＇s necessary to have a second taping at the halftime of the basketball game.
