学生体质指数与机能、素质指标关系的研究

Study on Relationship Between Body Mass Index and Function,Diathesis Among Students.

【目的】 了解中小学生的营养状况与其机能、素质指标间的关系 ,为儿童期肥胖与生存质量间关系的研究提供参考。 【方法】 采用LMS法拟合男女生的BMI的年龄别百分位数曲线 ,对同年龄、同性别高BMI组和低BMI组的机能、素质指标进行比较。 【结果】 高BMI组的血压、肺活量明显高于低BMI组 ,心率无显著差异 ;高BMI组的速度、力量、耐力和柔韧性指标均较低BMI组差 ,且有统计学意义 ,爆发力指标两组间无显著差异。 【结论】 学生的机能、素质受营养状况的影响 ,高BMI组的机能、素质较低BMI组差。

To learn the relationship between body mass index and function indexes,diathesis indexes among students, and to give help to the study on the relationship between child obesity and their quality of life. Age related centile of body mass index were fitted by using LMS method, function indexes and diathesis indexes were compared between higher BMI group and lower BMI group at same age and gender. Blood pressure and vital capacity among higher BMI groups were higher than that of lower BMI groups, there were no significant difference between the two groups heart rate. Velocity index, strength index, endurance index and flexibility index among higher BMI groups were lower than those among lower BMI groups, and there were significant difference between the two groups, there were no significant difference between the two group's explosive force.[Conclusions] Student function and diathesis were influenced by their nutrition states, function and diathesis among higher BMI groups were lower than that among lower BMI groups.
