The physiological responses of normal walking and walking on a dual action treadmill which incorporates arm exercise were compared in 29 men and 37 women. Subjects completed six, 5-min steady-state exercises at 2.0, 3.0, and 4.0 mph (0.89, 1.34, 1.79 m.s-1) and 3% incline with and without arms. Estimated METs calculated according to the ACSM equations were compared with the actual METs. The men's ventilation (VE), and VO2 (l.min-1, ml.kg-1.min-1, and METs) were significantly (P < 0.001) higher at all speeds and for both conditions than the women's. There were no gender differences (P > 0.05) in heart rates (HR), respiratory exchange ratio, and ratings of perceived exertion (RPE) for each condition. The arm conditions yielded significantly (P < 0.001) higher responses at each speed for VE, l.min-1, ml.kg-1.min-1, METs, RPE, and HR. Although there were no significant (P < 0.05) differences in HR between men and women for each condition, the relationships between ml.kg-1.min-1 and HR differed. The actual METs obtained during the arm conditions were significantly (P < 0.05) higher than those estimated for both the men and women at all speeds. It was concluded that using the arms while walking on a dual action treadmill increases the energy costs an average of 55% above normal walking.
对29名男性和37名女性在正常行走以及在结合手臂运动的双动跑步机上行走时的生理反应进行了比较。受试者在2.0、3.0和4.0英里/小时（0.89、1.34、1.79米/秒）的速度以及3%的坡度下，分别完成了六次5分钟的稳态运动，运动时有无手臂参与。根据美国运动医学学会（ACSM）公式计算的估计代谢当量（METs）与实际METs进行了比较。在所有速度和两种运动条件下，男性的通气量（VE）、耗氧量（VO2，单位：升/分钟、毫升/千克/分钟和METs）均显著高于女性（P < 0.001）。在每种运动条件下，心率（HR）、呼吸交换率和主观用力程度评分（RPE）均无性别差异（P > 0.05）。在每种速度下，手臂参与运动的条件下，VE、升/分钟、毫升/千克/分钟、METs、RPE和HR的反应均显著更高（P < 0.001）。尽管在每种运动条件下男性和女性的HR没有显著差异（P < 0.05），但毫升/千克/分钟与HR之间的关系有所不同。在手臂参与运动的条件下，所有速度下男性和女性实际测得的METs均显著高于估计值（P < 0.05）。研究得出结论，在双动跑步机上行走时使用手臂，能量消耗比正常行走平均增加55%。
