[Abstract]:Objective: to investigate the general trend and difference of P300 latency and amplitude of Pz in different age groups with different physical exercise methods and cycles. Methods: according to the principle of international consensus (Prisma principle), 12 articles of Chinese literature and 9 articles of foreign language were analyzed by Review5.3. The independent variable was physical exercise, and the dependent variable was P300 latency and amplitude of Pz. The indexes included effect quantity, heterogeneity test, sensitivity, publication bias, and subgroup analysis of different physical exercise methods, cycles and different age groups. Results: (1) the amplitude-effect value of P300 was 0.93, the latency effect value was dn-0.94, and the P value was less than 0.01. (2) it was found by subgroup analysis. The amplitude-effect value of P300 in the elderly was 1.87, the value of latency effect was less than 0.01, the value of amplitude effect of P300 in young people was 0.50, the value of latency effect was less than 0.01, and the value of independent sample T test was 0.001 / 0.038, respectively, which had statistical significance. (3) the amplitude-effect value of P300 over 7 weeks exercise was 1.25, the latency effect was less than 0.01w and less than 7 weeks, the amplitude-effect value of P300 was 0.76, the value of latency effect was less than 0.01, and the value of P300 was less than 0.01. The value of independent sample T test had P value of less than 0.01.The amplitude effect value of P300 was less than 0.76, and the value of latency effect was less than 0.01.The effect value of P300 was less than 0.01.The value of latency effect was less than 0.01. (4) the amplitude effect of P300 in leisure sports was 0.59, the latency was less than 0.01P, the amplitude effect of P300 was 1.22, and the latency was less than 0.01. (4) the amplitude-effect of P300 was less than 0.01, and the value of latency was less than 0.01in P300, and the amplitude effect of P _ (300) was less than 0.01, and the value of latency was less than 0.01.The value of P _ (300) was less than 0.01, and the value of P _ (300) was less than 0.01. Conclusion: (1) physical exercise has a great influence on P300 and has a better effect on the improvement of cognitive function. (2) compared with young people, physical exercise is more effective in improving the cognitive function of the elderly. (3) regardless of age or exercise style, physical exercise is more effective in improving the cognitive function of the elderly. The improvement of cognitive function during the exercise cycle of more than seven weeks is better than that of the exercise cycle of less than seven weeks. (4) whether we adopt physical sports or leisure sports, we can improve the cognitive function. The improvement effect of leisure item is better than that of leisure item in amplitude.
