Olfaction acuity, which includes detection thresholds, discrimination and identification, appears to decline with age, obesity, and various neurological disorders. Knowing that smell influences energy intake, there is a growing interest in protecting this sense. Physical activity could be a key intervention to counteract the loss of olfaction. This systematic review aims to explore the literature on the effect of physical activity on olfaction acuity. The search strategy consisted of using index terms and keywords in MEDLINE, EMBASE, EBM Reviews - Cochrane Central Register of Controlled Trials, CINAHL, SPORTDiscus, and Web of Science search engine. Data from 17 trials involving 10,861 participants showed that physical activity improved olfaction thresholds, discrimination, identification and perceived intensity. Regular practice of physical activity seemed to have better effects on olfaction components than acute exercise. Although this review has clarified the evidence on the effects of physical activity on olfaction, better methodological consistency is needed.
嗅觉敏锐度包括检测阈值、辨别力和识别力，似乎随年龄增长、肥胖和各种神经紊乱而下降。由于嗅觉会影响能量摄入，因此人们越来越关注保护这种感觉。身体活动可能是对抗嗅觉丧失的关键干预措施。本系统综述旨在探讨身体活动对嗅觉敏锐度的影响的文献。检索策略包括使用 MEDLINE、EMBASE、EBM Reviews - Cochrane 中央对照试验注册中心、CINAHL、SPORTDiscus 和 Web of Science 搜索引擎中的索引术语和关键词。涉及 10861 名参与者的 17 项试验的数据表明，身体活动可改善嗅觉阈值、辨别力、识别力和感知强度。有规律地进行身体活动似乎比急性运动对嗅觉成分有更好的效果。尽管本综述阐明了身体活动对嗅觉影响的证据，但需要更好的方法学一致性。
