Exercise can improve cognitive function. The impact of acute exercise on cognition is related to exercise intensity. This study aimed to explore whether normal walking had a beneficial effect on cognition.
Compared with standing still, thirty healthy young men walked on a treadmill at a normal pace, and completed the Stroop test. Near-infrared spectroscopy was used to monitor the hemodynamic changes of the prefrontal cortex during the entire experiment.
Studies showed that normal walking did not stimulate higher average cerebral oxygen in the PFC, but the peak cerebral oxygen in cognitive tests during walking was higher (Stroop Word: 2.56 ± 0.43 and 3.80 ± 0.50, P < 0.01, Stroop Color: 2.50 ± 0.37 and 3.66 ± 0.59, P < 0.05, Stroop Color-Word: 4.13 ± 0.55 and 5.25 ± 0.66, P < 0.01, respectively), and better results were achieved in the Stroop Color-Word test, which was reflected in faster reaction times (49.18 ± 1.68 s, 56.92 ± 2.29 s, respectively, P < 0.001) and higher accuracies (46.19 ± 0.69, 44.15 ± 0.91, respectively, P = 0.018).
For healthy young people, even a normal walk is therefore good for cognition.
运动可改善认知功能。急性运动对认知的影响与运动强度有关。本研究旨在探讨正常步行是否对认知有有益影响。
与静止站立相比,30名健康年轻男性以正常步速在跑步机上行走,并完成斯特鲁普测试。在整个实验过程中,使用近红外光谱监测前额叶皮层的血流动力学变化。
研究表明,正常步行并未刺激前额叶皮层产生更高的平均脑氧,但步行过程中认知测试时的脑氧峰值更高(斯特鲁普文字:2.56±0.43和3.80±0.50,P<0.01;斯特鲁普颜色:2.50±0.37和3.66±0.59,P<0.05;斯特鲁普颜色-文字:4.13±0.55和5.25±0.66,P<0.01),并且在斯特鲁普颜色-文字测试中取得了更好的结果,这体现在更快的反应时间(分别为49.18±1.68秒、56.92±2.29秒,P<0.001)和更高的准确率(分别为46.19±0.69、44.15±0.91,P=0.018)上。
因此,对于健康的年轻人来说,即使是正常步行也对认知有益。
