Go/No-go task; Reaction Time; Response Inhibition
This study examined the effect of short duration, moderate and high-intensity exercise on a Go/NoGo task. Fifteen, habitually active (9 females and 6 males aged 28 +/- 5 years) agreed to participate in the study and cognitive performance was measured in three sessions lasting 10 min each, performed at three different exercise intensities: rest, moderate and high. Results indicated significant exercise intensity main effects for reaction time (RT) (p = 0.01), the omission error rate (p = 0.027) and the decision error rate (p = 0.011), with significantly longer RTs during high intensity exercise compared to moderate intensity exercise (p = 0.039) and rest (p = 0.023). Mean +/- SE of RT (ms) was 395.8 +/- 9.1, 396.3 +/- 9.1 and 433.5 +/- 16.1 for rest, moderate and high intensity exercise, respectively. This pattern was replicated for the error rate with a significantly higher omission error and decision error rate during high intensity exercise compared to moderate intensity exercise (p = 0.003) and rest (p = 0.001). Mean +/- SE of omission errors (%) was 0.88 +/- 0.23, 0.8 +/- 0.23 and 1.8 +/- 0.46% for rest, moderate and high intensity exercise, respectively. Likewise, mean +/- SE of decision errors (%) was 0.73 +/- 0.24, 0.73 +/- 0.21 and 1.8 +/- 0.31 for rest, moderate and high intensity exercise, respectively. The present study's results suggest that 10 min workout at high intensity impairs RT performances in habitually active adults compared to rest or moderate intensity exercise.
