“…Interestingly, RT decreased when assessed by the CRT and flanker task, almost similar to changes that were observed in MT and PMT. An important finding of this review was that when PMT was assessed by the flanker test during aerobic exercise, PMT when compared to baseline [4,9]. This finding is consistent with previous systematic reviews that only examined RT [13,57].…”

“…Regardless of the cognitive task and exercise characteristics, MT and RT did not change immediately after aerobic exercise compared to the rest condition. However, this result should be interpreted with caution as there were only two studies that reported MT and RT after exercise [4,9].…”

“…In summary, 11 studies measured FRT during exercise. This includes seven studies used SRT [1-3, 5, 6, 9, 16], two studies used CRT [7,15], and three studies used the flanker task [4,9,52]. Nine studies used less than 20 min aerobic exercise [1,6,9,16,52] and three studies used more than 20 min aerobic exercise [7,9,15].…”

“…In summary, six studies measured FRT immediately after aerobic exercise. Dividing studies based on the cognitive function test revealed that three studies investigated the effect of aerobic exercise on SRT [1,3,9]; two studies investigated the effect of aerobic exercise on go/no-go task [26,27]; and two studies investigated the effect of aerobic exercise on the flanker task [9,28]. Two studies used less than 20 min aerobic exercise [3,26] and four studies used more than 20 min aerobic exercise [7,9,27,28].…”

“…This, paired with other factors such as non-randomly assigned participants to intervention groups, non-concealment of allocating to groups, nonblinding of data analysis, indicates a high potential for bias. Furthermore, regarding the duration of aerobic exercise, it should be noted that there were only three studies that measured FRT during aerobic exercise at more than 20 min [7,9,15]. One important moderator that influences cognitive performance is the duration of the aerobic exercise.…”

Recently, there have been several studies that have examined the acute effects of aerobic exercise on cognitive function. Importantly, one precise indicator of cognitive function is response time (RT), which has two main components; premotor time (PMT) and motor time (MT). PMT is the time for perception, decision making and response preparation, while MT is executing the response. Using fractionated response time (FRT) instead of RT provides a more precise estimate of the location of the effect of aerobic exercise on cognitive or motor components of the response. There is emerging evidence that shows an acute bout of exercise may improve FRT. Therefore, the purpose of this systematic review and meta-analysis was to explore the acute effect of aerobic exercise on FRT by considering the effects of various cognitive function tests. Fourteen studies were included investigating FRT during and/or after aerobic exercise. The results indicated that during exercise, PMT increased in simple reaction time and decreased in flanker task; MT decreased in choice reaction time; interestingly, RT decreased when it was assessed by choice reaction time and flanker task, almost similar to PMT and MT. After exercise, PMT decreased specifically in flanker and go/no-go tasks. However, MT and RT did not change significantly. In conclusion, as changes in RT are affected by both PMT and MT, FRT provides a more precise estimate of the locus of the effects of aerobic exercise on response time.
