摘要

目的：本研究目的為調查高中甲級籃球選手踝關節之背屈柔軟度、內外翻肌群等速肌力測試表現以及單腳站立平衡能力；慣用腳與非慣用腳之異同。方法：徵召高中甲級籃球選手36名，受試者三個月內無下肢受傷經驗且踝關節無疼痛等運動傷害症狀，以及接受所有訓練不影響其表現能力。受測項目依序為：踝關節背屈柔軟度；單腳站立平衡能力；踝關節等速肌力測試（肌力、肌力比值、肌耐力、力矩加速能量）。結果：離心肌力大於向心肌力，踝關節慣用側之內翻肌肌力和力矩加速能量比非慣用側大；肌力比值和外翻肌肌耐力，非慣用側大於慣用側；其餘變項在兩側之間並無達到統計上的差異。結論：高中甲級男子籃球選手因訓練和運動上的需要，致使慣用側和非慣用側踝關節在等速肌力多項測試表現上有差異，本研究結果可以作為籃球選手踝關節競技傷害後的治療與歸隊前的評估參考。

Objective: This study aimed to investigate ankle dorsiflexion flexibility, ankle invertor and evertor muscle isokinetic performance and balance during unilateral stance in high school division I basketball players. This study also aimed to investigate the similarities and differences between the dominant and non-dominant leg of the basketball players.Method: Thirty-six high school division I basketball players were recruited. The exclusion criteria were sustaining injuries in the lower limbs within the past 3 months and experiencing residual symptoms of pain in the ankle joints. Further, the study was conducted such that the test performances were not affected by the training that the players received. The test items used in this study included the following (listed in order): ankle dorsiflexion flexibility, balance when in a unilateral stance, and ankle isokinetic performance, which comprises muscle strength, muscle strength ratio, muscle endurance, and torque acceleration energy.Results: Eccentric muscle strength was observed to be greater than concentric muscle strength; further, ankle joint invertor muscle strength and torque acceleration energy were greater on the dominant side than on the non-dominant side, while muscle strength ratio and evertor muscle endurance were greater on the non-dominant side than on the dominant side. There was no significant statistical difference between the 2 sides in the other measurements.Conclusions: The differences in isokinetic performance between the dominant and non-dominant ankle joints of the high school division I male basketball players were caused by the need to meet the demands of their training and the rigors of the sport itself. The results of this study can be used as a reference when deciding the course of treatment for ankle injuries in athletes and basketball players. It can also be used while assessing whether injured basketball players are physically fit to rejoin the team.
