| （山西大学 体育学院，山西 太原 030006） 摘 要：对山西省3 406名BMI处在同一等级男大学生身体素质等指标进行分析。结果显示：大学男生BMI等级分布总体处于良好状态，体型正常的比例在75%左右；相同BMI等级独生与非独生男大学生身体素质间存在着一定的差异，主要表现为：独生男生在短距离、短时间、高强度快速爆发力项目略强于非独生男生，而在长距离的耐力跑等方面却明显落后于非独生男生，5项素质总体得分独生男生明显低于非独生男生；大学男生身体成分中，去脂体重与体脂率的不同是引起身体素质间差异的主要内在因素，即体脂率与脂肪含量成正比，与去脂体重及人体运动能力成反比；运动因素是引起独生与非独生男大学生身体素质差异的客观因素之一。 |
