| Popis: | PURPOSE This study aimed to compare the acute effects of different types (treadmill vs. cycle) of moderate-intensity aerobic exercise on cerebral blood flow and cognitive function in young adults. METHODS By a randomized crossover study design, ten participants were initially assigned to either treadmill exercise (TE; n=5) or cycle ergometer exercise (CE; n=5) and then they performed the other with seven-day wash-out period. Both exercises were implemented at the target heart rate corresponding to 70% of heart rate reserve for 30 minutes. Cognitive function was assessed by the Stroop Color-Word test at pre- and post-exercise. Cerebral blood flow was continuously monitored using near-infrared spectroscopy technique during rest, cognitive function test (CFT), and exercise. RESULTS There was a significant group by time interaction in tissue saturation index (TSI) (p=.046). Post-hoc analysis presented that TSI at post-exercise CFT was higher than during exercise in TE (p=.02). In both exercises, TSI at pre-exercise CFT significantly increased compared to the resting value (p=.001). Cerebral oxyhemoglobin level was significantly increased during exercise and at post-exercise CFT compared to the resting value in both exercises (p |
