Ankle disk training has been used as an exercise in sports medicine clinics to help protect against ankle sprains. This study investigated the effects of ankle disk training on the contraction pattern of the anterior tibialis, posterior tibialis, peroneus longus, and flexor digitorum longus muscles in a simulated ankle sprain. Twenty adults were recruited and divided into a control group and an experimental group. A platform with a trapdoor was used to simulate a lateral ankle sprain. Electromyographic data were recorded from each subject in pretraining and posttraining tests. The experimental group underwent ankle disk training for 8 weeks between the pretraining and posttraining tests. In the pretraining test, the four muscles started to contract simultaneously; in the posttraining test, the contractions of the anterior and posterior tibialis muscles were delayed. This delay favors the correction of excessive ankle inversion. This study examined the effects of one form of proprioceptive training on muscle reaction times, and its results may explain why such training can help protect against ankle sprains.
踝关节盘训练已在运动医学诊所中作为一种锻炼方式，用于预防踝关节扭伤。本研究调查了在模拟踝关节扭伤情况下，踝关节盘训练对胫骨前肌、胫骨后肌、腓骨长肌和趾长屈肌收缩模式的影响。招募了20名成年人，分为对照组和实验组。使用带有活动门的平台来模拟外侧踝关节扭伤。在训练前和训练后的测试中记录每个受试者的肌电图数据。实验组在训练前和训练后的测试之间进行了8周的踝关节盘训练。在训练前的测试中，四块肌肉同时开始收缩；在训练后的测试中，胫骨前肌和胫骨后肌的收缩延迟。这种延迟有利于纠正过度的踝关节内翻。本研究考察了一种本体感觉训练形式对肌肉反应时间的影响，其结果可能解释了为什么这种训练有助于预防踝关节扭伤。
