To investigate the effect of long leg compression garments on the postural sway and balance ability of female athletes at a state sports institute.
A laboratory was set up to analyse kinetic and kinematic variables using a double blind, randomised controlled repeated measures cross over design.
Participants were required to perform a single leg balance task for up to 60s across six conditions; including eyes-open and eyes-closed while wearing conventional shorts (control), loose-fitted compression garment and well-fitted compression garments. Simultaneous measurements of ground reaction forces and full body joint kinematics were recorded. Postural stability was assessed by measuring the overall stabilisation time as well as the movement of the centre of pressure (CoP) and centre of mass (CoM) from baseline measures.
During one leg stance, significantly greater postural stability (p < 0.01) was observed with eyes open vs eyes closed, irrespective of compression group. A significantly greater (p < 0.05) balance time was observed with eyes closed when wearing well-fitted compression garments compared to conventional shorts. Differences were not present with use of the loose-fitted garment. Additionally, a significant interaction effect between compression condition and vision was observed analysing the variation about the sway (swaySD) of the CoP and CoM data (p < 0.05). The interaction effect revealed greater variability of movement with eyes closed as participants' level of compression decreased. No significant differences were observed with eyes open.
The difficulties of postural stability while maintaining the single leg stance wearing conventional shorts were improved with use of the well-fitted compression garments (in the eyes-closed condition). Proper fitted compression garments may be beneficial for injury management and injury prevention.
探究长筒压缩袜对州立体育学院女性运动员姿势摆动和平衡能力的影响。
建立实验室，采用双盲、随机对照重复测量交叉设计分析运动学和运动学变量。
参与者需要在 6 种条件下完成单腿平衡任务，持续 60 秒，包括睁眼和闭眼，同时穿着传统短裤（对照）、宽松压缩衣和贴合的压缩衣。同时记录地面反作用力和全身关节运动学的测量值。通过测量整体稳定时间以及从基线测量得出的压力中心（CoP）和质心（CoM）的移动，评估姿势稳定性。
在单腿站立期间，无论压缩组如何，睁眼时的姿势稳定性明显更高（p < 0.01）。与传统短裤相比，闭眼时穿着贴合的压缩衣可显著延长平衡时间（p < 0.05）。穿着宽松的压缩衣时没有差异。此外，分析 CoP 和 CoM 数据的摆动（摆动 SD）时，观察到压缩条件和视觉之间存在显著的交互作用（p < 0.05）。交互作用表明，随着参与者的压缩水平降低，闭眼时的运动变异性更大。睁眼时没有观察到显著差异。
在穿着传统短裤保持单腿站立时，姿势稳定性的困难通过使用贴合的压缩衣得到改善（在闭眼状态下）。合适的压缩衣可能对损伤管理和预防有益。
