有氧运动对单纯性肥胖儿童身体素质和心肺机能的影响
中文摘要
目的:儿童肥胖是一种以身体脂肪含量过多为主要特征、多病因的、严重危害青
少年健康发育的慢性病,是学校体育与健康教育领域亟待解决的问题。本文以肥胖小
学生为观察对象,采用身体素质评价、身体成分、肺功能和心电图等检测方法,探讨
有氧运动干预对单纯性肥胖少年儿童身体机能的影响,目的为正确指导肥胖小学生的
体育锻炼提供科学依据。
方法:选取肥胖小学男生30名(±,±)和正
常对照组30名(±,±(cm)作为研究对象,观察了有氧
运动对肥胖儿童身体素质、身体成分、肺功能和心电图等指标的变化。
有氧运动采用韵律体操、单人跳绳、双人跳绳、往返跑等四种运动形式交替进行,
每次运动40min,准备活动10min, 每周4次,总持续时间为12周。
结果:(1)肥胖组运动锻炼前后体脂肪量、体脂肪百分率和去脂肪量明显改善
(P<);(2)肺功能指标中,肥胖组运动前后FRC、MVV、V50/Ht、PEFR等指
标均发生了明显改善(P<),FEV1运动锻炼前后变化最为明显,呈非常显著性差
异(P<);(3)心电图指标中。肥胖儿童QTd和QTcd均明显下降,运动锻炼前
后比较均呈显著性差异(P<)。
结论:(1)肥胖可以使儿童通气阻力增加,导致肺部的通气功能下降,运动可
以使肺脏的通换气功能得到改善。(2)肥胖儿童的心电图QT离散度延长,说明肥胖
已经明显增加了儿童的心脏负担,有氧运动对儿童心脏具有一定的保护作用。

Effect of Aerobic exercise on obesity children's Physical and
cardioPulmonary function
Abstract
PurPose: Childhood obesity is a kind of chronic disease whose main characteristics is
too much body fat content, and harm to adolescent health develoPment, which is the school
Physical education and health education field Problem to be solved. Based on the Primary
school students of obesit for observation, Physical quality evaluation and Position,
Pulmonary function testing methods and electrocardiogram were adoPted to study the
effect of aerobic exercise interventions on obesity young children's body function, in order
to Provide the scientific basis for Physical exercise for Primary school students of obesity.
Method: 30 Primary school boys of obesity(age ± year olds, body height
±) and 30 normal control boys(age ± year olds, body height ±
) were chosen as the research object, to observe th
