摘要

目的：双脚负荷的对称性和充分的姿势控制是正确深蹲表现的关键方面。本研究旨在评估深蹲时各种站立宽度对姿势控制和双脚负荷对称性的影响：方法：30 名健康人参加了这项研究。每位参与者分别以窄站姿（NS）、臀部站姿（HS）和宽站姿（WS）进行一种类型的深蹲：结果：与 NS 和 HS 深蹲相比，WS 深蹲的 CoP 路径长度、摆动速度和 Area95 值明显更高。此外，宽脚设置不仅明显影响了双脚加载的对称性，还影响了策略（高 LyE）、不规则量（高 SampEn）和 CoP 时间序列粗糙度复杂性（高 FD）。结果表明，随着支撑基数的增加，不对称指数也在增加：宽蹲的稳定性较差，需要更复杂的姿势控制行为和更大的灵活性。进行这种深蹲时，压力会明显转移到优势肢体上。

Influence of the base of support widths on postural control and feet loading symmetry during squat - preliminary study.

Purpose: The symmetry of feet loading and adequate postural control are crucial aspects of proper squat performance. The study aimed to evaluate the effect of various stance widths during squat on postural control and symmetry of feet loading.

Methods: Thirty healthy individuals participated in this study. Each participant performed one type of squat with a narrow stance (NS), hip stance (HS) and wide stance (WS).

Results: A significantly higher value of CoP path length, the velocity of sways and Area95 were obtained for the WS squat compared to NS and HS. In addition, the wide feet setting significantly affected not only the feet loading symmetry but also the strategy (high LyE), the amount of irregularities (high SampEn) and the CoP time-series roughness complexity (high FD). It has been shown that as the base of support grew, the asymmetry index grew.

Conclusions: The wide squat is less stable, requiring more complex postural control behavior and more flexibility. Performing this squat significantly shifts the pressure to the dominant limb.
