國內高中甲級籃球選手踝關節柔軟度、肌力與單腳站立平衡能力之初步研究

Abstract

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.
