The energy cost of level walking and level and grade running was determined in 7 active women with max VO2 = 50.7 ml/kg-min. Speeds investigated were 4 to 8 km/hr walking and 8 to 14.5 km/hr running. The validity coefficients of several procedures for estimating energy expenditure during locomotion [4 for running (6)(11)(16)(17); 3 for walking (6)(12)(17)] were determined. Correlation coefficients between actual and predicted values were 0.949 to 0.951 with standard errors of estimate 0.79 to 0.80 kcal/kg-hour for walking and 0.856 to 0.975 with standard errors of estimate 0.40 to 0.60 kcal/kg-hour for running. VO2 and kcal energy cost values were similar to those previously reported on men at equivalent walking and running speeds. Efficiency of running based on lift work done was about 25%. Lift work for women was slightly less than values previously reported for men at walking but was slightly more at running. These differences did not appear to have a significant effect on energy expenditure.
对7名最大摄氧量为50.7毫升/千克·分钟的活跃女性进行了平路行走以及平路和上坡跑步的能量消耗测定。研究的速度为4至8千米/小时的行走速度以及8至14.5千米/小时的跑步速度。确定了几种用于估算运动过程中能量消耗的方法的效度系数[跑步的有4种(6)(11)(16)(17)；行走的有3种(6)(12)(17)]。行走时实际值与预测值之间的相关系数为0.949至0.951，估计标准误差为0.79至0.80千卡/千克·小时；跑步时相关系数为0.856至0.975，估计标准误差为0.40至0.60千卡/千克·小时。在相同的行走和跑步速度下，摄氧量和千卡能量消耗值与之前报道的男性的值相似。基于所做提升功的跑步效率约为25%。女性的提升功在行走时略低于之前报道的男性的值，但在跑步时略高于男性。这些差异似乎对能量消耗没有显著影响。
