采用体脂率法对３所小学中９～１３岁９７５名儿童（肥胖儿３７２名，正常儿６０３名）进行身高、体重、机能指标测试。其中随机选取２７３名儿童（肥胖儿１８９名，正常儿８４名）进行素质指标测试。结果表明：（１）男女生舒张压各肥胖组均比正常组高（Ｐ＜０．０５）。（２）５０ｍ、８００ｍ（女）／１０００ｍ（男）各肥胖组均比正常组差（Ｐ＜０．０５）。儿童肥胖对运动速度、耐力有影响。（３）男生各肥胖组爆发力均比正常组差（Ｐ＜０．０１）。（４）男女生各肥胖组肌力水平均低于正常级（Ｐ＜０．０１或Ｐ＜０．０５）。
Body fat rate was used to test the height, weight and function of 975 children aged 9-13 years (372 obese children and 603 normal children) in three primary schools. Among them, 273 children (189 obese children and 84 normal children) were randomly selected for quality test. The results showed that: (1) Diastolic blood pressure was higher in boys and girls than in normal people (P <0.05). (2) The obesity group of 50m, 800m (female) / 1000m (male) was worse than the normal group (P <0.05). Children obesity on the speed of exercise, endurance impact. (3) The explosive power of each obese group was worse than that of normal group (P <0.01). (4) Muscle levels in obesity group were lower than those in normal group (P <0.01 or P <0.05).
