Abstract

Cognitive function is reported to improve by moderate aerobic exercise. However, the effects of intermittent exercise with rest between the moderate-intensity exercise are unclear. Therefore, this study aimed to compare the effects of continuous and intermittent exercise on cerebral oxygenation and cognitive function. This study included 18 healthy adults. For the continuous exercise protocol, 5 min of rest was followed by 30 min of exercise; 5 min of rest was allowed after each exercise. For the intermittent exercise protocol, 3 sets of 10 min of exercise were completed, with 5 min of rest between the sets. Exercise intensity was 50% of maximum oxygen uptake. Oxyhemoglobin (OHb) in the prefrontal cortex (PFC) was measured during each protocol, and cognitive tasks (Stroop test) were performed before and after exercise. OHb levels for the left and right PFCs were significantly higher post-exercise than pre-exercise for both exercise protocols (p < 0.01). The average reaction time in the Stroop test was significantly shorter post-exercise than pre-exercise for both protocols (p < 0.01). There was no significant difference in the error rate pre- and post-exercise for both protocols (continuous p = 0.22; intermittent p = 0.44). There was no significant difference between both protocols in all measurement results (OHb: p = 0.67; average reaction time p = 0.50; error rate p = 0.24). OHb was higher and average reaction time was shorter after exercise than before exercise for both exercise protocols. Intermittent and continuous exercise may improve cognitive function to the same degree after exercise.

摘要

认知功能据称通过适度的有氧运动得到改善。然而，在中等强度运动之间休息的间歇性运动的效果尚不清楚。因此，本研究旨在比较连续运动和间歇性运动对脑氧合和认知功能的影响。本研究纳入了 18 名健康成年人。在连续运动方案中，运动后休息 5 分钟，然后进行 30 分钟的运动；运动后允许休息 5 分钟。在间歇性运动方案中，完成 3 组 10 分钟的运动，组间休息 5 分钟。运动强度为最大摄氧量的 50%。在每个方案中测量前额叶皮层（PFC）的氧合血红蛋白（OHb），并在运动前后进行认知任务（Stroop 测试）。对于两种运动方案，左、右 PFC 的 OHb 水平在运动后均显著高于运动前（p<0.01）。对于两种方案，Stroop 测试的平均反应时间在运动后均显著短于运动前（p<0.01）。对于两种方案，运动前后的错误率均无显著差异（连续运动 p=0.22；间歇性运动 p=0.44）。两种方案的所有测量结果之间均无显著差异（OHb：p=0.67；平均反应时间 p=0.50；错误率 p=0.24）。两种运动方案后，OHb 均升高，平均反应时间均缩短。间歇性和连续运动可能在运动后以相同程度改善认知功能。
