在20-65岁健康男性水平步行和自行车运动中测定了心率、通气量和摄氧量。由于大多数临床工作试验都必须进行，这些试验是在没有任何手术经验的受试者身上进行的。心率和耗氧量之间的关系与年龄和工作类型无关。老年人步行时的通气当量（Ve/Vo2）较高。骑自行车时不同年龄的耗氧量相同，步行时随年龄的增长而增加。给出了水平行走耗氧量的预测公式。这些可以用来大致估计不同速度下的氧运输负荷，但如果需要对身体健康进行更彻底的分析，就应该确定实际的摄氧量。
Heart rate, ventilation volume and oxygen uptake have been determined in level walking and bicycle ergometry in healthy men, 20-65 years old. The tests have been performed on subjects with no preceeding experience with the procedure, as most clinical work tests have to be carried out. The relationship between heart rate and O2 consumption is independent of age and type of work. The ventilatory equivalent (Ve/Vo2) is higher in the older ages in walking. The oxygen consumption is the same in different ages in cycling, but increases with age in walking. Equations are given for the prediction of oxygen consumption at level walking. These can be used to give an approximate estimation of the load of the oxygen transportation at different speeds, but a determination of the actual oxygen uptake ought to be made if a more thorough analysis of physical fitness is desired.
