内蒙古大学生BMI指数与身体素质的相关性研究

Correlation Studies with BMI and Physical Fitness of College Students in Inner Mongolia

根据《2014年全国学生体质与健康调研》内蒙古自治区数据库的高校数据资料，选取握力、50 m 跑、立定跳远、引体向上（仰卧起坐）、800 m 跑（1000 m 跑）和坐位体前屈等指标，研究内蒙古蒙汉族大学生 BMI 指数与身体素质的相关性.将研究对象按照 BMI 指数分为肥胖、超重、正常、偏瘦4种类型，检验不同类型之间身体素质的差异性.结果显示，蒙古族和汉族大学生 BMI 指数与身体素质项目之间存在不同程度的相关性（相关系数-0.282-0.254）；体重正常和偏瘦型学生的50 m 跑、立定跳远、引体向上/仰卧起坐、800 m/1000 m 跑等项目的成绩明显高于肥胖和超重型；BMI 指数越大握力成绩越好；坐位体前屈未见明显差异.
