Abstract

Objective: Evaluate the effect of backpack load location on postural sway and correlate sway path length (PL) to anthropometrics and body composition.

Methods: Fifteen participants aged 18-25 stood on a force plate with backpack load located high (LH), low (LL) or without backpack (NL). Body composition and anthropometric variables were correlated to PL.

Results: Load increased PL, 95% confidence ellipse, and mean velocity while it reduced mediolateral SampEn (p<0.05). Females had increased mean velocity and PL of sway (p<0.05). Larger phase angles correlated with reduced PL under NL. Taller individuals correlated with reduced PL under LL. Greater mass correlated with reduced PL under LH.

Conclusions: Load carriage regardless of load location increased postural sway metrics except mediolateral SampEn. Females had greater PL and mean velocity compared to males. Select anthropometric and body composition variables correlated with postural sway under different load conditions.

健康年轻人背包负荷位置、性别、人体测量和身体成分因素与姿势摆动的关系。

目的：评估背包负荷位置对姿势摆动的影响，并将摆动路径长度（PL）与人体测量和身体成分相关联。方法：15名18-25岁的参与者站在一块力板上，背包负荷位于高（LH）、低（LL）或无背包（NL）。结果：负荷增加PL，和平均速度，而它降低了中侧SampEn（P结论：除中侧Samp En外，无论负载位置如何，负载都会增加姿势摆动指标。与男性相比，女性具有更大的PL和平均速度。选择不同负载条件下与姿势摆动相关的人体测量和身体成分变量。
