To investigate the effects of unilateral isokinetic exercises on the one-legged standing balance of the contralateral lower extremity.
A volunteer sample of 32 healthy adults (12 men and 20 women) was randomized to training and control groups.
The training group received unilateral hip isokinetic exercises of the dominant leg for two weeks. Contralateral single-limb balance was measured before and after intervention, including three stability index scores of balance using Biodex Stability System: Anterior-Posterior Stability Index (APSI), Medio-lateral Stability Index (MLSI), and Overall Stability Index (OSI) scores.
Comparison of pre-test and post-test data revealed significant improvements in APSI, MLSI, and OSI scores in the training group (p<0.05), but not in the control group. The gains of stability scores from pre- to post-test, were also significantly greater (p<0.05) in the training group than the control group.
These results suggest that contralateral training with unilateral isokinetic exercises increases the one-legged standing balance of the contralateral limb following a short duration of training.
探讨单关节等速运动对健侧下肢单腿站立平衡的影响。
志愿者样本 32 名健康成年人（12 名男性，20 名女性）被随机分为训练组和对照组。
训练组接受为期两周的优势腿单侧髋关节等速运动。干预前后分别测量健侧单腿平衡，包括 Biodex 稳定性系统的三个平衡稳定性指数评分：前-后稳定性指数（APSI）、中-侧稳定性指数（MLSI）和整体稳定性指数（OSI）评分。
与测试前相比，训练组的 APSI、MLSI 和 OSI 评分在测试后均显著提高（p<0.05），而对照组则没有。与对照组相比，训练组从测试前到测试后的稳定性评分提高幅度也显著更大（p<0.05）。
这些结果表明，单侧等速运动的对侧训练可以在短时间的训练后增加对侧肢体的单腿站立平衡。
