OBJECTIVE: The aim of this study was to investigate the test-retest reliability of isokinetic and isometric lower limb peak torque to body mass of muscles acting on the hip, knee, and ankle in female team sport athletes. It was hypothesised the test-retest reliability would be good (intraclass correlation coefficients (ICC) ≥ 0.75).
METHODS: Thirty-eight female athletes (Australian Rules Football = 18, netball = 12, soccer = 8) aged 16-35 years participated in this study. Participants performed isokinetic (60°/s and 120°/s) and isometric testing on a Biodex Isokinetic Dynamometer on three separate days.
RESULTS: Poor to good reliability was demonstrated for all joint movements (ICC = 0.38-0.88) with small to moderate effect sizes (0.00-0.43) and typical errors (5.65-24.49).
CONCLUSIONS: Differences in peak torque to body mass were observed between sessions one and two and/or one and three, demonstrating a learning effect. Therefore, three testing sessions, and/or the inclusion of a familiarisation session, is recommended for future assessments in populations unfamiliar with dynamometry.
目的:这项研究的目的是研究等速和等距下肢峰值扭矩对髋关节肌肉体重的测试-重测可靠性,膝盖,女性团体运动运动员的脚踝。假设重测可靠性良好(组内相关系数(ICC)≥0.75)。
方法:38名16-35岁的女运动员(澳大利亚规则足球=18,无挡板篮球=12,足球=8)参加了这项研究。参与者分别在三天内在Biodex等速测功机上进行了等速(60°/s和120°/s)和等距测试。
结果:所有关节运动(ICC=0.38-0.88)的可靠性都较差,具有小到中等的效应大小(0.00-0.43)和典型的误差(5.65-24.49)。
结论:在第一和第二和/或第一和第三阶段之间观察到峰值扭矩对体重的差异,展示学习效果。因此,三个测试会议,和/或包括一个熟悉的会议,建议在不熟悉测力的人群中进行未来评估。
