有氧运动对记忆的影响及其神经生物学机制

Objective Aerobic exercise is the rhythmic and continuous use of large muscle groups with sufficient oxygen supply. The aim of this review is to summarize previous research regarding the effects of aerobic exercise on working memory, episodic memory and implicit memory, and moderators among the relationships. Methods The following databases were used for the computerized searches: CNKI, Web of Science and PubMed. Results Aerobic exercise can improve processing speed in working memory tasks. Moderate to vigorous intensity aerobic exercise before memory encoding or during consolidation can enhance episodic memory. Vigorous intensity aerobic exercise can promote implicit memory. Acute aerobic exercise can increase brain-derived neurotrophic factor (BDNF), induce long-term potentiation, activate hippocampus and other memory related brain areas, while chronic aerobic exercise can improve neurogenesis. Limitations Future research should focus on aerobic exercise timing, aerobic exercise duration, aerobic exercise intensity, and other moderating roles, such as cognitive engagement during aerobic exercise, gender and age, and to further elucidate the neurobiological mechanisms underlying effects of aerobic exercise on different types of memory.
