The effects of ankle guards and taping on joint motion before, during, and after exercise were studied. Twelve league squash players played two matches, each lasting 1 hour. Two different ankle guards, and two types of tape applied by the same method, served as supports. A specially designed goniometer with electronic digital display (accuracy 1 degree) was used to determine joint range of motion: plantar-flexion and dorsiflexion, neutral inversion and eversion, plantar-flexed inversion and eversion. The results were statistically analyzed to determine the significance of the restriction provided by the supports. This revealed that the two ankle guards provided no significant support. The two tapes, however, provided significant support before exercise and after 10 minutes but not after 1 hour of exercise. Nonelastic (zinc oxide) tape proved to be the most restrictive at all times measured, especially prior to exercise, when the ankle's range of motion was decreased between 30% and 50%. However, once exercise commenced, the tape stretched, and restriction became less effective.
研究了运动前、运动中和运动后护踝和贴扎对关节活动的影响。12名联赛壁球运动员进行了两场比赛，每场比赛持续1小时。两种不同的护踝以及用相同方法贴扎的两种类型的胶带作为支撑物。使用一种专门设计的带有电子数字显示（精度为1度）的测角仪来确定关节活动范围：跖屈和背屈、中立位内翻和外翻、跖屈位内翻和外翻。对结果进行统计分析以确定支撑物所提供限制的显著性。结果表明，两种护踝均未提供显著支撑。然而，两种胶带在运动前和运动10分钟后提供了显著支撑，但在运动1小时后则没有。在所有测量时间内，非弹性（氧化锌）胶带被证明限制作用最强，尤其是在运动前，此时踝关节活动范围减少了30%至50%。然而，一旦开始运动，胶带会伸展，限制作用就会减弱。
