有氧中等强度持续运动（MCE）可以通过激活生理和心理因素来急性改善执行功能（EF）。最近，据报道，高强度间歇运动（HIIE）比MCE更有利于身体适应。与MCE相比，HIIE可能更能增强EF改善的因素;但HIIE对EF的影响尚不清楚。因此，我们的目的是研究在何种程度上HIIE影响运动后EF运动后立即和运动后恢复，与传统的MCE相比。12名健康男性受试者以随机和平衡顺序进行基于HIIE或MCE协议的自行车测力计运动。HIIE方案包括4次4分钟的发作，90%的峰值VO2，3分钟的主动恢复，60%的峰值VO2。在峰值VO2的60%下应用容量匹配的MCE方案。为了评估EF，颜色词Stroop任务进行前和运动后。HIIE和MG方案在运动后即刻EF的改善是相同的。然而，HIIE对EF的改善在运动后恢复的30分钟内持续存在，在此期间MCE恢复到运动前水平。运动后恢复时的EF反应与生理和心理反应的变化有关。本研究结果表明，HIIE和MCE能够改善EF。此外，HIIE可以延长运动后恢复期间EF的改善。我们首次提出HIIE可能是比MCE更有效的改善EF的策略。(C)2015 Elsevier Inc.

Aerobic moderate-intensity continuous exercise (MCE) can improve executive function (EF) acutely, potentially through the activation of both physiological and psychological factors. Recently, high-intensity interval exercise (HIIE) has been reported to be more beneficial for physical adaptation than MCE. Factors for EF improvement can potentially be more enhanced by HIIE than by MCE; but the effects of HIIE on EF remain unknown. Therefore, we aimed to examine to what extent HIIE impacts post-exercise EF immediately after exercise and during post-exercise recovery, compared with traditional MCE. Twelve healthy male subjects performed cycle ergometer exercise based on either HIIE or MCE protocols in a randomized and counterbalanced order. The HIIE protocol consisted of four 4-min bouts at 90% of peak VO2 with 3-min active recovery at 60% of peak VO2. A volume matched MCE protocol was applied at 60% of peak VO2. To evaluate EF, a color-words Stroop task was performed pre- and post-exercise. Improvement in EF immediately after exercise was the same for the HIIE and MG protocols. However, the improvement of EF by HIIE was sustained during 30 min of post-exercise recovery, during which MCE returned to the pre-exercise level. The EF response in the post-exercise recovery was associated with changes in physiological and psychological responses. The present findings showed that HIIE and MCE were capable of improving EF. Moreover, HIIE could prolong improvement in EF during post-exercise recovery. For the first time, we suggest that HIIE may be more effective strategy than MCE for improving EF. (C) 2015 Elsevier Inc.
