| ABSTRACT |
|
Activity change in the central nerve system according to the cardio exercise level.
[PURPOSE] The purpose of this study is to examine any changes in perceptive & cognitive functions through maximal exercise & 3-step sub-maximal exercise with equally set total exercise amount. In addition, it is to examine the degree of difference in exercise intensive in the case of showing changes in cognitive function.
[METHOD] In this study, 6 male university students were selected as research subjects. In terms of exercise intensity, it was set in 4 steps of 40VO2max, 60%VO2max and 80%VO2max sub-maximal exercise and 100%VO2max maximal exercise based on the maximum oxygen intake amount of subject (VO2max). In addition, exercise time for each intensity was set with equal exercise intensity x time (min.) by considering the 100%VO2max intensity of reaching total exhaustion.
[RESULTS] There was a trend of increasing P300 amplitude after exercise. In terms of the main effect of pre- & post-exercise and main effect of deduction area revealed meaningful differences of F(1,5)=29.52, p<0.05, F(2,10)=18.8 p<0.01. As for the sub-verification of deduction area, meaningful differences were shown with Fz & Cz and p<0.05 between Fz & Cz and p<0.01 between Fz & Pz. In the sub-verification of exercise intensity, meaningful differences of p<0.05 was shown between 60%VO2max & 100%VO2max. In the P300 latency period, it showed differences of F(3,15)=2.78(p<0.10) in the main effect of exercise intensity. In the sub-verification of exercise intensity, meaningful differences of p<0.05 between 40VO2max & 60%VO2max, and p<0.01 between 40VO2max & 80%VO2max were shown. In the P300 latency period of 0VO2max condition, it showed a trend of shortening compared to 60%VO2max & 80%VO2max exercise conditions.
[CONCLUSION] In the sensory & stimulation processing of promoting response selection for external stimulation, no differences were shown between the pre- & post-exercise and exercise intensity regarding the speed of perception & cognitive functions.
