大学生有氧运动中肺功能的测定与分析

To Anlysis Lung Function about University Student During Aerobic Exercise

本项目用德国CORTEXMetaLyzer便携式肺功能测试仪测试两组大学生运动过程中心率、摄氧量氧脉搏、相对摄氧量、肺通气量、肺通气量与肺摄氧量比值、呼吸商和呼吸频率.为保证运动强度相同,利用跑台等时(5min)递增负荷强度的跑步运动,共选取40例实验对象,在心率与呼吸功能诸多指标的相关系数的研究中,得出心率与相对于二氧化碳的通气当量的相关系数,由极显著负相关转变为极显著正相关.

This project tested the heart rate,the amount of oxygen and pulse absorbing,the amount of oxygen relatively,the keeping in touch with amount of lung,the ratio of keeping in touch amount of lung and taking quantity of lung,respiratory exchanging ratio and respiratory ratio for the university students in two groups with the portable lung function tester CORTEX MetaLyzer from Germany.In order to guarantee the intensity of sport to be the same,they are required to run on the platform for increasing progressively intensity.The forty students are chosen for the experimental subjects altogether.Obtain the research of the breathe function and the heart rate has found the coefficient correlation of equivalent to transfer limit positive correlation to notably extremely.
