肥胖对小学生体能影响的配对研究

A Matched Study on Physical Ability in Obese Pupils

目的 探索肥胖对小学生体能的影响。方法 应用标准方法,对104名9～11岁肥胖儿童及其对照进行体能测试。结果 肥胖组学生的收缩压/舒张压、单位体重肺活量、单位瘦体重肺活量与对照组有显著差异;肥胖儿童的50米跑、立定跳远、仰卧起坐、1分钟跳绳得分均显著低于对照组儿童,且与体质指数呈显著负相关;肥胖儿童的握力与对照组无显著性差异,背肌力显著高于对照组。结论 肥胖儿童的心肺功能、速度、耐力、爆发力及协调性等素质较非肥胖儿童差。肥胖儿童的肌力未受损,甚至高于非肥胖儿童。

OBJECTIVE This study was conduted to determine whether obesity affect the physical ability of pupils. METHOD The physical a-bility of 104 obese children ages 9 - 11 and their counterparts were tested. RESULTS Obese children had significantly higher systolic and dias-tolic blood pressure than the controls. Obese children s vital capacity/weight and vital capacity/lean body weight were lower than the normal-weight children.The scores of 50-meter-running,standing long jump,sitting up and rope skipping in a minute in obese children were significantly less than those of the normal-weight children.There was negative correlation between the scores and body mass index. Back muscle strength in obese children was higher.There was no difference in grip strength between two groups. CONCLUSIONS The results indicate that obese children's heart-lung function and physical fitness such as speed,endurance,explosive force, coordination and flexibility are poorer and their motor a-bility is lower than non-obese children.The result shows that obese children's muscle strength has not been impaired.
