一、前言在体力测定中,做为定量负荷的方式有多种,其中台阶实验有其独特的优点。一些学者的研究表明利用台阶实验可测定受试者的耗氧量,从而间接推测其最大耗氧量。由于其简便实用,因而被广泛采用。文献中报告的台阶实验有不少是用受试者的体重和台阶负荷的心率来推测:Vo_2max的,其中以Astrand的列线图影响最大。然而在实际工作中,人们会提出这样的疑问,受试
I. INTRODUCTION In physical testing, there are many ways to do quantitative load, in which bench experiments have their unique advantages. Some scholars have shown that the use of bench tests to determine the subject’s oxygen consumption, which indirectly estimates the maximum oxygen consumption. Because of its simple and practical, it is widely used. Many of the bench tests reported in the literature are based on the subject’s body weight and step load heart rate: Vo_2max, of which the Astrand nomogram has the greatest impact. However, in practical work, people will put forward such questions, test
