This study investigated the acute influence of exercise on eating behaviour in an ecologically valid setting whereby healthy active males were permitted complete ad libitum access to food. Ten healthy males completed two, 8h trials (exercise and control) in a randomised-crossover design. In the exercise trials participants consumed a breakfast snack and then rested for 1h before undertaking a 60 min run (72% of VO(2)max) on a treadmill. Participants then rested in the laboratory for 6h during which time they were permitted complete ad libitum access to a buffet meal. The timing of meals, energy/macronutrient intake and eating frequency were assessed. Identical procedures were completed in the control trial except no exercise was performed. Exercise increased the length of time (35 min) before participants voluntarily requested to eat afterwards. Despite this, energy intake at the first meal consumed, or at subsequent eating episodes, was not influenced by exercise (total trial energy intake: control 7426 kJ, exercise 7418 kJ). Neither was there any difference in macronutrient intake or meal frequency between trials. These results confirm that food intake remains unaffected by exercise in the immediate hours after but suggest that exercise may invoke a delay before food is desired.
这项研究在生态有效的环境中调查了运动对进食行为的急性影响，在这种环境中，健康活跃的男性可以自由进食。10 名健康男性以随机交叉设计完成了两项 8 小时的试验（运动和对照）。在运动试验中，参与者吃了早餐小吃，然后休息 1 小时，然后在跑步机上进行 60 分钟的跑步（72%的 VO2max）。然后，参与者在实验室中休息 6 小时，在此期间他们可以自由进食自助餐。评估了用餐时间、能量/宏量营养素摄入和进食频率。在对照试验中完成了相同的程序，只是没有进行运动。运动后，参与者自愿要求进食的时间提前了 35 分钟。尽管如此，第一餐或随后的进食中摄入的能量并不受运动影响（总试验能量摄入：对照 7426kJ，运动 7418kJ）。试验之间的宏量营养素摄入或进食频率也没有差异。这些结果证实，运动后立即进食不会受到影响，但运动可能会在想吃食物之前引起延迟。
