          Abstract

          Objective The present study aims to investigate the association of functional exercise performance and pulmonary function in obese children, and to provide a reference for improving motor ability of obese children.

          Methods A total of 55 obese (obese group) and 57 healthy children with normal body weight (control group) were enrolled and pulmonary function as well as functional exercise performance were determined by spirometry and six-minute walk test (6 MWT), respectively.

          Results The 6 MWT distance (6MWD) in obese group was lower than that of control group [obese group (546.1±67.9) m, control group (610.4土 70.1) m, P<0.01]. In terms of pulmonary function parameters, forced expiratory volume in 1 sec (FEV1) and forced mid-expiratory flows (FMEF) were lower in the obese group than control group [FEV1: obese group (93.3±9.4)%, control group (99.5±16.4) %, P = 0.02; FMEF: obesegroup(100.2±11.4)%, controlgroup(109.4±19.1)%, P =0.002], whereas forced vital capacity (FVC), the FEV1/FVC ratio and peak expiratory flow (PEF) were not statistically different between the two groups. Partial correlation analysis revealed that among all parameters, only body mass index (BMI) was negatively associated with 6MWD ( r = −0.31, P = 0.03).

          Conclusion Functional exercise performance and pulmonary function of obese children deteriorates as compared to those of healthy children. BMI might be the independent predictor for functional exercise performance.

          【摘要】 目的 探讨肥胖儿童功能性运动能力与肺功能的关系, 为改善肥胖儿童运动能力提供参考。 方法 选取郑 州市某小学 55 名肥胖儿童 (肥胖组) 与 57 名体重正常的健康儿童 (对照组), 利用肺量计测定肺功能, 利用 6 min 步行实验 (6 MWT) 测定功能性运动能力。 结果 肥胖组儿童 6 min 内步行距离 (6 MWD) [(546.1±67.9) m] 低于对照组 [(610.4土 70.1) m] ( t = −4.90, P<0.01)。肺功能测试指标中, 肥胖组第1 s用力呼气量 (FEV1) [(93.3±9.4)%] 和用力呼气中期流量 (FMEF) [(100.2±11.4)%] 低于对照组 [(99.5±16.4) %, (109.4±19.1) %], 差异均有统计学意义 (t 值分别为−2.45, −3.11, P值均<0.05), 用力肺活量 (FVC), FEV1/FVC 以及呼气流量峰值 (PEF) 两组间比较差异均无统计学意义 ( P值均>0.05)。偏相关分析显示, 在各参数中仅身体质量指数 (BMI) 与 6 MWD 呈负相关 ( r = −0.31, P = 0.03)。 结论 肥胖儿童功能性运 动能力与肺功能均低于健康儿童, BMI是功能性运动能力的独立预测变量。
