不同强度健身跑对女大学生身体成分和肺通气功能的影响

Effects of different intensity jogging on female college students' body composition and pulmonary ventilation function

为提高大学生阳光体育冬季长跑的实效性,探讨不同强度有氧健身跑对女大学生身体成分和肺通气功能的影响,选择北京林业大学60名大二健康女大学生为研究对象,运用文献资料法、教学实验法和数理统计法,进行了16周不同强度组别健身跑实验。结果发现:中、小强度健身跑锻炼对学生身体成分的影响显著,在脂肪百分比、身体质量指数、腰臀比指标均值改变的幅度最大,差异最显著(p<0.01);高强度健身跑锻炼对身体成分的影响较小;通过对不同强度组学生两项肺功能指标测试,三种强度的健身跑使学生的肺功能指标均有一定幅度的提高,但中等强度健身跑对学生肺功能影响最大,提高幅度最明显,两项指标均呈现显著性差异(p<0.01)。

In order to improve the effectiveness of long-distance running in winter in College Students＆#39; Sunshine Sports and discuss the different aerobic fitness running effects on female college students ’body composition and pulmonary ventilation function, this paper chose our school’s 60 healthy female college students in the second grade as the research object. Through 16 weeks of different strength group fitness running experiments, results showed that：low and Medium intensity group has the greater influence on body composition, three indexes such as the largest percentage of fat, body mass index and waist hip ratio of the average magnitude of the change have the most significant difference （p＆lt;0.01）.High intensity group is the smallest. According to two indices of pulmonary function test of the different groups, three intensity jogging enable students to increase pulmonary function indices, but the pulmonary function of students of medium intensity of jogging can be improved significantly. There are significant differences （p＆lt;0.01） between two pulmonary ventilation indicators.
