The objective of the present study was to determine the effects of exercise continued until the anaerobic threshold on balance performance in basketball players. Twelve male basketball players (age = 20.92 ± 2.81 years, body height = 192.72 ± 7.61 cm, body mass = 88.09 ± 8.41 kg, training experience = 7.17 ± 3.10 years) volunteered to participate in this study. A Kinesthetic Ability Trainer (KAT 2000 stabilometer) was used to measure the balance performance. Balance tests consisted of static tests on dominant, nondominant and double leg stance. The Bruce Protocol was performed by means of a treadmill. The exercise protocol was terminated when the subject passed the anaerobic threshold. After the exercise protocol, balance measurements were immediately repeated. Statistical differences between pre and post-exercise for dominant, nondominant and double leg stance were determined by the paired samples t-test according to the results of the test of normality. The post-exercise balance score on the dominant leg was significantly higher than pre-exercise (t = -2.758, p < 0.05). No differences existed between pre- and post-exercise in the balance scores of the nondominant leg after the exercise protocol (t = 0.428, p > 0.05). A significant difference was found between pre and post-exercise balance scores in the double leg stance (t = -2.354, p < 0.05). The main finding of this study was that an incremental exercise continued until the anaerobic threshold decreased balance performance on the dominant leg in basketball players, but did not alter it in the nondominant leg.
本研究的目的是确定持续到无氧阈的运动对篮球运动员平衡表现的影响。12 名男性篮球运动员（年龄=20.92±2.81 岁，身高=192.72±7.61cm，体重=88.09±8.41kg，训练经验=7.17±3.10 年）自愿参加了这项研究。使用 Kinesthetic Ability Trainer（KAT 2000 平衡仪）测量平衡表现。平衡测试包括优势腿、非优势腿和双腿站立的静态测试。Bruce 方案通过跑步机进行。当受试者通过无氧阈时，运动方案即终止。运动方案后，立即重复平衡测量。根据正态性检验的结果，采用配对样本 t 检验确定优势腿、非优势腿和双腿站立的运动前后平衡测试的统计学差异。运动后，优势腿的平衡得分显著高于运动前（t=-2.758，p<0.05）。运动方案后，非优势腿的平衡得分在运动前后无差异（t=0.428，p>0.05）。在双腿站立的平衡测试中，运动前后的平衡得分有显著差异（t=-2.354，p<0.05）。本研究的主要发现是，持续到无氧阈的递增运动降低了篮球运动员优势腿的平衡表现，但对非优势腿没有影响。
