Increased energy expenditure (EE) is a key component in maintaining a healthy body mass. Walking and running are 2 common aerobic activities that increase EE above resting values. The purpose of this study was to compare the EE of individuals with average fitness during a walk and run for 1600 meters at 86 m·min(-1) and 160 m·min(-1), respectively. In addition, EE after the walk and run was compared. Fifteen females and 15 males (21.90 ± 2.52 y; 168.89 ± 11.20 cm; 71.01 ± 17.30 kg; 41.51 ± 6.31 ml(-1)·kg(-1)·min(-1)) volunteered to participate. Each participant completed a VO2max test. In addition, oxygen consumption was measured at rest for 10 minutes before exercise, during the walk and run, and after the walk and run for 30 minutes of recovery. EE during exercise was 372.54 ± 78.16 kilojoules for the walk and 471.03 ± 100.67 kilojoules for the run. Total EE including excess postexercise EE was 463.34 ± 80.38 kilojoules and 664.00 ± 149.66 kilojoules for the walk and run, respectively. Postexercise EE returned to resting values 10 minutes after the walk and 15 minutes after the run. Walking and running are both acceptable activities that increase EE above rest and can be performed without the expense of a health club membership and meet adequate kilojoule expenditure according to American College of Sports Medicine guidelines.
能量消耗的增加是维持健康体重的关键组成部分。步行和跑步是两种常见的有氧运动，可使能量消耗高于休息时的值。本研究的目的是比较在以 86 m·min(-1) 和 160 m·min(-1)的速度分别步行和跑步 1600 米时，体能一般的个体的能量消耗。此外，还比较了步行和跑步后的能量消耗。15 名女性和 15 名男性（21.90 ± 2.52 岁；168.89 ± 11.20 cm；71.01 ± 17.30 kg；41.51 ± 6.31 ml(-1)·kg(-1)·min(-1)）自愿参加。每位参与者都完成了 VO2max 测试。此外，在运动前休息 10 分钟时、步行和跑步过程中以及步行和跑步后 30 分钟恢复期间测量了耗氧量。步行时的运动中能量消耗为 372.54 ± 78.16 千焦耳，跑步时为 471.03 ± 100.67 千焦耳。包括运动后过量能量消耗在内的总能量消耗分别为步行 463.34 ± 80.38 千焦耳和跑步 664.00 ± 149.66 千焦耳。步行后 10 分钟和跑步后 15 分钟，运动后的能量消耗恢复到休息时的值。步行和跑步都是可接受的增加能量消耗的活动，可在无需健身俱乐部会员资格的情况下进行，并且根据美国运动医学学院的指南，满足足够的千焦耳消耗。
