Abstract: Physical activity has become an important factor for delaying cognition aging of the elderly, improving cognition functions of teenagers, and improving student learning, etc, however, exercise prescription design based on specific cognition benefits still needs to be explored. The authors probed into the dose-effect relationships be-tween physical activity intensity, physical activity time, physical activity frequency, total physical activity volume, physical activity type and cognition benefit from the perspectives of one-time physical activity and long-term physical activity respectively. On such a basis, the authors put forward that future research should focus on consid-ering the overall design of 4 physical activity elements, considering the cognition benefits of different physical ac-tivity events, examining the cognition benefits of physical activities of different groups of people, examining the mechanism of dose-effect relationships of the cognition benefits of physical activities, and then provide evi-dence-based criteria for making cognition benefit promoting physical activity plans.
