最大吸氧量直接、间接测定法的效果比较

Comparison between the direct and indirect measurement of maximum quantity of respiratory oxygen

为比较直接测定法与间接测定法测定最大吸氧量的效果差异,于2006-11选择湖南师范大学体育学院男性大学生30名(足球专选15名,田径专选15名),应用心肺功能测试系统进行最大吸氧量直接测定,应用多别恩台阶实验方法间接测定最大吸氧量。检测结果显示间接测定法得到的最大吸氧量值高于直接测定[(3.70±0.56),(3.30±2.61)L/min,P<0.01]。说明了运用多别恩台阶实验方法间接测定最大吸氧量的准确性不高,其作为体质监测指标的有效性、可比性值得思考。

To compare the differences in the measurement of maximum quantity of respiratory oxygen （VO2 max） between direct and indirect methods, we selected 30 male students from the College of Physical Education, Hunan Normal University including 15 football players and 15 track and field players in November 2006. The VO2max was measured directly with the cardio-pulmonary function test, and measured indirectly with Doblen step test. The results showed that the VO2max measured by indirect method was higher than that by direct method [（3.70±0.56）, （3.30±2.61） L per minute, P 〈 0.01], indicating that it was not accurate to measure VO2max with Doblen step method, so its validity and comparability is worthy considering if serving as an index of physique physique.
