This narrative review of the medical literature assessed whether outdoor and indoor physical activity would increase the plasma levels of vitamin D. Synthesis of this liposoluble vitamin is mainly mediated by sunlight on the skin, where it is activated to perform its main action, which is to control the serum levels of calcium as soon as the element is absorbed in the intestines, assisting in the regulation of bone metabolism. Physical activity is any body movement that results in energy expenditure, while outdoor physical activity refers to physical activity carried out at public parks or other open spaces, as is the case of the popular practice of taking walks. Exercising outdoors would have both the benefits of physical activity and of sun exposure, namely the synthesis of vitamin D. However, according to the studies analyzed, increased plasma concentration of vitamin D occurs with physical activity both indoors and outdoors.
这篇医学文献的叙述性综述评估了户外和室内体育活动是否会提高血浆维生素D水平。这种脂溶性维生素的合成主要由皮肤接受阳光介导，在皮肤中它被激活以发挥其主要作用，即一旦钙在肠道被吸收，就控制血清钙水平，协助调节骨代谢。体育活动是指任何导致能量消耗的身体运动，而户外体育活动是指在公园或其他开放空间进行的体育活动，比如常见的散步。在户外锻炼既有体育活动的益处，又有阳光照射的益处，即维生素D的合成。然而，根据所分析的研究，无论在室内还是室外进行体育活动，血浆维生素D浓度都会升高。
