我国大学生隐形肥胖者的体质形态和体力特征

Characteristics of anthropometrics and physical fitness of masked obesity in university students

研究了我国大学生"隐形肥胖者"分布特点及形态和体力特征。对男女大学生各1200名进行体质测试,结果如下:1)男女隐形肥胖者分布比率为4.6%和10.3%;2)女性隐形肥胖者的BMI21和23组的腰围、腰围/臀围与对照组比较,有明显差异,而男子组却没有这种规律;3)男子在体力方面,隐形肥胖组中的BMI20、22、23组背力、握力、坐位体前屈和垂直纵跳,BMI21组的垂直纵跳,与对照组比较,明显下降。而女子除BMI各组背力外,均无明显差异;4)男子在运动能力方面,隐形肥胖组中的BMI各组除50m跑和立定跳远外,与对照组比较无明显差异,而女子除BMI22、23组50m跑和23组的立定跳远外,均无明显差异。研究表明女子隐形肥胖者是男子的2.24倍,在形态方面,女子隐形肥胖的腰围增大;而在体力方面,特别男子的肌肉力量和爆发力比较差。

The purpose of this study was to investigate the characteristics of anthropometrics and physical fitness between controls and masked obesity included 2400 university students which 1200 were men and 1200 were women. Their anthropometrics and physical fitness were tested. The results were as follows: 1) The percentage of masked obesity showed to be 4.6% of men and 10.3% of women.2) The waist and WHR of masked obesity group of the BMI 21 and 23 groups in women were significantly higher than those of the controls. 3) The back strength, grasp power,sitting trunk flexion and vertical jump of masked obesity group of the BMI 20,22 and 23 groups, and vertical jump of BMI21 group in men were significantly lower than those of the controls.But except that back strength of masked obesity group, the same changer was not found in women. 4) For physical fitness in men,50M and standing jump of masked obesity group in the all BMI were not significantly different.But except that 50M of masked obesity group of the BMI 22 and 23 groups and standing jump of the BMI23 group in women,others were not significantly different.The above data,indicates that the waist of masked obesity in women was larger in anthropometry,and the muscle strength and power of masked obesity in men were lower than non-obese subjects.
