尽管据报道，剧烈的运动对执行功能有有益的影响，但不活跃的人可能会发现很难开始锻炼。在这项研究中，我们专注于产生成就感的家务活动（HA），需要适度的体力活动。我们研究了急性发作的HA对执行功能和流向相关皮质区域的氧合血红蛋白（oxygenated hemoglobin，oxy-Hb）的影响。25名参与者（年龄，18-21岁;平均年龄，19.88±0.60岁; 6名男性和19名女性）接受了两项实验，即HA和对照实验，这些实验在不同的日期进行。在HA实验中，参与者用吸尘器清理脏地板，在对照实验中，参与者在干净的地板上用拔出的吸尘器模仿同样的动作。实验期间记录的心率显示，对照组和HA组之间的体力活动强度没有显著差异。一份问卷调查显示，完成HA实验后有一种成就感。参与者进行了Stroop色字任务（SCWT）前和实验后，皮质血流动力学的变化，同时监测使用功能近红外光谱。实验前后，HA组SCWT总反应的Stroop干扰分数的变化显著高于对照组，SCWT正确反应的Stroop干扰分数的变化趋势与HA组相似。Stroop干扰分数的变化，氧血红蛋白流到右腹外侧前额叶皮层（R-VLPFC）表现出相同的趋势。因此，通过激活PFC（包括R-VLPFC），HAs可能比其他体力活动对执行功能产生更大的有益影响。
Although acute bouts of exercise reportedly have beneficial effects on executive function, inactive people may find it difficult to start exercising. In this study, we focused on housework activities (HAs) that generate a sense of accomplishment and require a mild intensity of physical activity. We examined the impact of an acute bout of HA on executive function and oxygenated hemoglobin (oxy-Hb) flow to related cortical regions. Twenty-five participants (age, 18–21 years; mean, 19.88±0.60 years; six males and 19 females) underwent two experiments, ie, HA and control experiments, which were conducted on different days. Participants vacuumed a dirty floor in the HA experiment and mimicked the same motion with an unplugged vacuum cleaner on a clean floor in the control experiment. Heart rate recorded during the experiments showed no significant difference in the intensity of physical activity between control and HA groups. A questionnaire revealed a sense of accomplishment after completing the HA experiment. Participants performed the Stroop color–word task (SCWT) pre- and post-experiments; cortical hemodynamic changes were simultaneously monitored using functional near-infrared spectroscopy. Variation in Stroop interference scores for SCWT total response between pre- and post-experiments was signifi-cantly higher in the HA group than in the control group, and that for SCWT correct response showed a similar trend. Variation in the Stroop interference score for oxy-Hb flow to the right ventrolateral prefrontal cortex (R-VLPFC) showed the same trend. Thus, HAs may have a greater beneficial effect on executive function than other physical activities through the activation of PFC, including R-VLPFC.
