湖南省肥胖中学生心肺机能特点研究

Cardiovascular fitness features for obese middle school students in Hunan province

为探讨肥胖对中学生心肺机能的影响,运用文献资料、数理统计法等方法,分析了湖南省20所城乡中学15 600名学生的体质测试及体检结果,并将1 263名肥胖中学生的心肺机能的相关指标与正常体重中学生进行比较。结果显示:肥胖中学生的基础心率、安静时心率、血压均高于体重正常的中学生,并与其体脂百分比呈正相关,肺活量虽略大于体重正常的中学生,但肺活量指数却小于体重正常的中学生并与其体脂百分比呈负相关。研究表明:肥胖中学生心肺机能低于正常体重中学生,并与其体脂百分比有相关性。建议社会重视中学生肥胖问题,及时采取积极的措施纠正肥胖并预防肥胖的发生。

In order to explore the obese influnce to the cardiovascular fitness, this paper ardyzes the results of the physical fitness test and medical ability inspection which involves 15,600 students from 20 rural and urban middle schools in Hunan province with the methods of mathematical statistics and literature review. And meanwhile some index related with cardiovascular fitness for 1,263 obese students is compared with normal weight students. The results indicates that the basal heart rate, quiet heart rate and blood pressure for obese students are all higher than that of normal weight students, positively correlative to the body fat percentage （PBF）. Their lung volume is slightly better, however, the lung volume index is lower than normal weight students ,inversely associated with the PBF. Studies have shown that the cardiovascular fitness for obese students is lower than those of normal weight and related with their PBF. It is proposed to attach adequate importance,so that active measuers are adopted to adjust and prevent the obese.
