This study investigated the effects of preventative ankle taping on planned change-of-direction and reactive agility performance and peak ankle muscle activity in basketballers. Twenty male basketballers (age = 22.30 ± 3.97 years; height = 1.84 ± 0.09 meters; body mass = 85.96 ± 11.88 kilograms) with no ankle pathologies attended two testing sessions. Within each session, subjects completed six planned and six reactive randomized trials (three to the left and three to the right for each condition) of the Y-shaped agility test, which was recorded by timing lights. In one session, subjects had both ankles un-taped. In the other, both ankles were taped using a modified subtalar sling. Peak tibialis anterior, peroneus longus (PL), peroneus brevis (PB), and soleus muscle activity was recorded for both the inside and outside legs across stance phase during the directional change, which was normalized against 10-meter sprint muscle activity (nEMG). Both the inside and outside cut legs during the change-of-direction step were investigated. Repeated measures ANOVA determined performance time and nEMG differences between un-taped and taped conditions. There were no differences in planned change-of-direction or reactive agility times between the conditions. Inside cut leg PL nEMG decreased when taped for the planned left, reactive left, and reactive right cuts (p = 0.01). Outside leg PB and soleus nEMG increased during the taped planned left cut (p = 0.02). There were no other nEMG changes during the cuts with taping. Taping did not affect change-of-direction or agility performance. Inside leg PL activity was decreased, possibly due to the tape following the line of muscle action. This may reduce the kinetic demand for the PL during cuts. In conclusion, ankle taping did not significantly affect planned change-of-direction or reactive agility performance, and did not demonstrate large changes in activity of the muscle complex in healthy basketballers. Key pointsAnkle taping using the modified subtalar sling will not affect planned change-of-direction or reactive agility performance as measured by the Y-shaped agility test in healthy male basketball players.Ankle taping using the modified subtalar sling will also generally not affect the activity of the muscles about the ankle. There was some indication for reductions in the activity of the PL in the inside leg of certain cuts.The tape used for the modified subtalar sling may have supported the line of action of the PL, which could reduce the kinetic demand placed on this muscle, and provide a potential fatigue-reducing component for cutting actions.The subtalar sling taping of the ankle in healthy basketball players did not have any adverse effects on the muscle activity of the ankle-foot complex during planned change-of-direction or reactive agility performance tasks.
本研究调查了预防性踝关节贴扎对篮球运动员的计划变向和反应敏捷性表现以及踝关节肌肉峰值活动的影响。20名无踝关节病变的男性篮球运动员(年龄 = 22.30 ± 3.97岁;身高 = 1.84 ± 0.09米;体重 = 85.96 ± 11.88千克)参加了两次测试。在每次测试中,受试者完成了Y形敏捷性测试的六项计划和六项反应性随机试验(每种情况向左和向右各三项),测试由计时灯记录。在一次测试中,受试者双踝关节未贴扎。在另一次测试中,双踝关节使用改良距下吊带进行贴扎。在变向过程中的站立阶段,记录了双腿内侧和外侧的胫骨前肌、腓骨长肌(PL)、腓骨短肌(PB)和比目鱼肌的峰值肌肉活动,并将其与10米短跑肌肉活动(nEMG)进行标准化。研究了变向步骤中内侧和外侧切入腿的情况。重复测量方差分析确定了未贴扎和贴扎条件下的表现时间和nEMG差异。两种条件下计划变向或反应敏捷性时间没有差异。在进行计划向左、反应向左和反应向右切入时贴扎后,内侧切入腿的PL nEMG降低(p = 0.01)。在贴扎的计划向左切入过程中,外侧腿的PB和比目鱼肌nEMG增加(p = 0.02)。贴扎过程中的其他切入动作中,nEMG没有其他变化。贴扎不影响变向或敏捷性表现。内侧腿的PL活动降低,可能是因为贴扎沿着肌肉作用线。这可能会降低切入时PL的动力需求。总之,踝关节贴扎对计划变向或反应敏捷性表现没有显著影响,并且在健康篮球运动员中,踝关节肌肉复合体的活动也没有明显变化。要点在健康男性篮球运动员中,使用改良距下吊带进行踝关节贴扎不会影响通过Y形敏捷性测试测量的计划变向或反应敏捷性表现。使用改良距下吊带进行踝关节贴扎通常也不会影响踝关节周围肌肉的活动。在某些切入动作中,内侧腿的PL活动有降低的迹象。用于改良距下吊带固定的贴扎可能支撑了PL的作用线,这可以减少该肌肉的动力需求,并为切入动作提供潜在的减少疲劳的作用。在健康篮球运动员进行计划变向或反应敏捷性表现任务时,距下吊带踝关节贴扎对踝足复合体的肌肉活动没有任何不利影响。
