摘要
目的:自行研制一种可适用于我国学生心肺功能评价的实验仪器,并对该仪器检测结果的准确性、安全性、可信性进行验证。方法:随机选取北京师范大学普通系大学生61名(男生33名,女生28名)作为受试者,采用本实验室自行研制的最大摄氧量测评仪和Cortex Metalyzer 3B心肺功能仪对受试者进行最大摄氧量测定;并测试受试者1 000 m(男子)或800 m(女子)跑运动成绩。测试过程中用POLAR心率表动态监测受试者心率;测试结束后根据Borg主观疲劳程度表换算出RPE值。结果:利用最大摄氧量测评仪检测受试者最大摄氧量的绝对值或相对值与直接测试方法所获得的结果之间无显著差异(P>0.05);1 000 m或800 m跑成绩与最大摄氧量绝对值与相对值之间呈负相关,相关系数较低(r<0.43);受试者在完成1 000 m和800 m跑过程中所测得的各项心率和主观疲劳程度RPE值均显著高于最大摄氧量测评仪测试过程中的各项指标值(P<0.01)。结论:1 000 m或800 m跑成绩用于评价人体的心肺功能水平缺乏科学性,建议选用最大摄氧量指标。本实验室自行研制的最大摄氧量测评仪,不仅检测结果准确、可信,而且具有简便、安全等优点,便于在大规模的学生心肺功能评价中推广应用。
Objective： To develop an instrument that be applied to evaluate students＇ cardiopulmonary function,and the test accuracy,safety and credibility of the instrument.Methods： Selecting 61 Beijing Normal University students（33 boys and 28 girls） randomly as subjects,using the oxygen uptake assessment instrument developed by laboratory and Cortex Metalyzer 3B instrument to test the maximum oxygen uptake,and take the male 1 000 m and female 800 m running test.Results： The result of direct VO2 max and indirect VO2 max using oxygen uptake assessment instrument have no obvious difference with direct VO2 max test（P 0.05）,the results of male 1 000 m and female 800 m running test has the negative correlation with direct VO2 maxand indirect VO2 max,and the correlation coefficient is low（r 0.43）,and rating of perceived exertion test result of male 1 000 m and female 800 m test is higher than stairs experiment（P 0.01）.Conclusion： Male 1 000 m and female 800 m to evaluate cardiopulmonary function is lack of scientific;The result of VO2 max instrument is more accurate,moderate,and secure,it can be applied to the scale of the students physique assessment in great scale.
