Abstract：Objective To explore differences of time perception in different exercise capacity groups with/without memory load and provide new evidence for physical activity promoting brain health. Methods In September 2015, 21 high level athletes, 15 physical education college students, and 18 normal college students were enrolled in the study as the subjects in Jiangxi Normal University. The model of the memory load and time of dual task paradigm（memory task × time task) was used. E-prime 2.0 software version of the psychological experiment was used to design the process, which would test a 2.5 s perception by the time producing method. Results ① In the time task without memory load, the time estimates by high level athletes and sports professional college students were closed to standard pitch, and that of ordinary college students was significantly higher than standard pitch. ② In the time task with memory load, both physical education college and normal college students' estimated time was significantly shorter than that without memory load (P<0.05). But high level athletes were not affected by memory load. ③ The average error of estimated time of high level athletes was significantly less than those of the students of physical education college and normal college. Conclusion The ability of time perception accuracy, stability, and anti-interference of high level athletes is the best among the three groups, which shows the advantage of the sense of time promoted by physical activity. This includes the time perception accuracy, stability, and anti-jamming capability.
