To determine the differences in gait, balance, muscle strength, and physical activity in young children who are healthy weight (HW), overweight (OW), or obese.
Participants (n = 70; 5-9 years) were classified according to their body mass index as OW/obese (n = 29) or HW (n = 41). Data were collected on gait parameters, 1-leg stance test (OLST), handgrip strength, vertical jump (VJ) height, and physical activity. An independent t test, Mann-Whitney U test, analysis of covariance (ANCOVA), and regression analyses were carried out.
Being OW/obese resulted in a significantly increased base of support while walking (P < .05), decreased OLST performance (P < .05), and decreased VJ height (P < .01) compared with peers of HW.
These findings suggest that in young children, being OW/obese may lead to an increased base of support while walking, decreased balance, and decreased leg explosive strength.
确定健康体重（HW）、超重（OW）或肥胖的幼儿在步态、平衡、肌肉力量和身体活动方面的差异。
参与者（n = 70；5 - 9岁）根据体重指数分为超重/肥胖组（n = 29）或健康体重组（n = 41）。收集了步态参数、单腿站立测试（OLST）、握力、垂直跳跃（VJ）高度和身体活动的数据。进行了独立t检验、曼-惠特尼U检验、协方差分析（ANCOVA）和回归分析。
与健康体重的同龄人相比，超重/肥胖导致行走时支撑面显著增加（P < .05），单腿站立测试表现下降（P < .05），垂直跳跃高度下降（P < .01）。
这些发现表明，在幼儿中，超重/肥胖可能导致行走时支撑面增加、平衡能力下降和腿部爆发力下降。
