摘 要:对比急性中等强度持续运动(MICT)和高强度间歇运动(HIIT)对注意缺陷症状男大学生抑制控制的影响,采用功能性近红外光谱技术(fNIRS)探究其脑机制。采用随机交叉设计,受试者按随机顺序接受3种干预措施(MICT、HIIT和静坐休息),并在干预前、干预后20和50 min进行色词Stroop任务和fNIRS测量,共20名受试者完成所有试验。结果表明,MICT和HIIT均改善Stroop任务的正确率,但HIIT仅在干预后50 min的不一致条件下有显著改善(t=3.41,P=0.002)。此外,MICT显著改善Stroop一致任务的反应时(t=-4.12,P=0.001)并持续至运动后50 min(t=-3.45,P=0.001)。运动后20 min,MICT显著提高一致条件任务下右侧腹外侧前额叶皮质(R-VLPFC)的激活状态(t=2.92,P=0.005),且反应时和R-VLPFC激活改善正相关(r=-0.37,P=0.02)。研究认为,相较于HIIT,MICT对抑制控制任务的更多维度产生显著改善,R-VLPFC激活增加可能是MICT改善抑制控制的潜在机制。

Abstract: To compare the effects of acute moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on inhibitory control in male university students with attention deficit symptoms, and to explore their underlying neural mechanisms using functional near-infrared spectroscopy (fNIRS), this study employed a randomized crossover design and then participants underwent three interventions (MICT, HIIT, and sedentary rest) in random order. Color-word stroop task and fNIRS measurements were also conducted before the intervention and 20 and 50 minutes post-intervention. A total of 20 subjects completed all trials. Both MICT and HIIT improved accuracy in the Stroop task, but however, a significant improvement in the incongruent condition was observed only 50 minutes after HIIT intervention (t=3.41, P=0.002). The study also found that MICT significantly improved reaction time in the congruent Stroop task (t=-4.12, P=0.001), and this effect persisted for 50 minutes post-exercise (t=-3.45, P=0.001). Twenty minutes post-exercise, MICT significantly increased activation in the right ventrolateral prefrontal cortex (R-VLPFC) during congruent condition tasks (t = 2.92, P = 0.005). Furthermore, the improvements in reaction time were positively correlated with the increases in R-VLPFC activation (r =-0.37, P = 0.02). The conclusion reveals that compared to HIIT, MICT resulted in significant improvements across more dimensions of inhibitory control tasks, and then the increase in R-VLPFC activation may be a potential mechanism through which MICT enhances inhibitory control.
