: This study investigated whether acute exercise duration affects inhibition in late middle-aged adults. : Over four separate days, 40 late middle-aged adults completed, in a counterbalanced order, three exercise sessions consisting of single bouts of moderate-to-vigorous intensity cycling, with the main acute exercise durations being 10, 20, and 45 min, and a control session consisting of 30 min of reading. Their inhibition performance was then evaluated by administration of the Stroop test following each session. : The participants had shorter mean response times for both the congruent and neutral conditions of the Stroop following the acute exercise lasting 20 min than they did after the control session. The acute exercise lasting 20 min also resulted in shorter response times for both conditions of the Stroop than the acute exercise lasting only 10 min. Meanwhile, the acute exercise lasting 45 min resulted in a shorter mean response time for the neutral Stroop condition than did the control session. Finally, the acute exercise lasting 20 min resulted in the shortest mean response time of all four sessions for the Stroop incongruent condition. : The above findings suggest that the moderate-to-vigorous intensity acute exercise lasting 20 min facilitated multiple cognitive function domains in general, whereas the exercise sessions of shorter and longer duration had negligible effects on executive function in the late middle-aged adults. These results highlight the need to consider the duration of any moderate-to-vigorous intensity exercise when developing acute exercise programs to facilitate executive function in aged populations.
本研究调查了急性运动时长是否会影响中老年成年人的抑制能力。在四个不同的日子里，40名中老年成年人以平衡的顺序完成了三个运动时段，每个时段包括一次中等到高强度的骑行，主要的急性运动时长分别为10分钟、20分钟和45分钟，还有一个由30分钟阅读组成的对照时段。然后在每个时段后通过施测斯特鲁普测验来评估他们的抑制能力表现。与对照时段相比，在持续20分钟的急性运动后，参与者在斯特鲁普测验的一致和中性条件下的平均反应时间更短。持续20分钟的急性运动在这两种条件下的反应时间也比仅持续10分钟的急性运动更短。同时，持续45分钟的急性运动在斯特鲁普测验中性条件下的平均反应时间比对照时段更短。最后，在斯特鲁普测验不一致条件下，持续20分钟的急性运动在所有四个时段中导致的平均反应时间最短。上述研究结果表明，持续20分钟的中等到高强度急性运动总体上促进了多个认知功能领域，而较短和较长时长的运动时段对中老年成年人的执行功能影响可忽略不计。这些结果凸显了在制定急性运动计划以促进老年人群执行功能时，需要考虑任何中等到高强度运动的时长。
