本研究考察了在不稳定移动平台上进行单腿站立测试时，支撑腿的偏侧性对姿势稳定性的影响及其练习效果。采用全向稳定性指数（OSI）对30名男大学生在不稳定移动平台上进行单腿站立测试（三次试验）。踢球时使用的腿被定义为操纵腿（ML），支撑腿被定义为非操纵腿（NML）。根据双向重复测量方差分析（ANOVA; trials × legs），仅在腿因素上观察到统计学上的显著差异，第二次和第三次试验中ML的OSI值小于NML。两腿之间的相关性有统计学意义，但不高。在稳定性方面，ML优于NML，在任何一条腿的试验中都没有明显的实践效果。
This study examined the laterality of the supporting leg in postural stability during a one-leg stance test on an unstable moving platform and its practice effect. 30 male university students were evaluated using the omnidirection stability index (OSI) during a one-leg stance test on an unstable moving platform (three trials). The leg used when kicking a ball was defined as the manipulation leg (ML) and the supporting leg was defined as the non-manipulation leg (NML). According to the two-way repeated measures analysis of variance (ANOVA; trials × legs), a statistically significant difference was observed only on the leg factor, and OSI values of the second and third trials were less for the ML than the NML. The correlation between both legs was statistically significant but not high. The ML was superior to NML with regard to stability, and no practice effect with trials was evident in either leg.
