（天津体育学院 竞技运动心理与生理调控重点实验室，天津 301617） 摘 要：身体活动已成为延缓老年人认知老化、提高青少年认知功能、改善学生学习等的重要因素，然而基于特定认知效益的锻炼处方设计仍需探索。研究分别从单次身体活动和长期身体活动角度探讨身体活动强度、身体活动时间、身体活动频率、身体活动总量、身体活动类型与认知效益之间的量效关系。在此基础上，提出未来研究应该重点考虑身体活动4个要素的整体设计、考虑不同身体活动项目的认知效益、考察不同人群身体活动的认知效益、考察身体活动认知效益量效关系的机制等，进而为制定促进认知效益的身体活动方案提供循证依据。

（Key Laboratory of Competitive Sport Psychological and Physiological Regulation，Tianjin University of Sport，Tianjin 301617，China) 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. |
