Relationship between vitamin D and physical activity: systematic review and meta-analysis

Vitamin D plays an important role in immune function and inflammation and the physical activity demonstrate relationship near to syntheses of vitamin D, considering to necessary to factors immunologics, environmental and physical. We searched five databases through February 20, 2021. Two reviewers screened the studies, collected data, assessed the risk of bias, and ranked the evidence for each outcome across the studies, independently and in duplicate. The prespecified endpoints of interest were Cardiorespiratory Fitness; Sunlight Exposure; Body Mass Index (BMI). We only included data from peer-reviewed articles in our primary analyses. In our primary analysis, there was a positive trend between serum 25(OH)D <20 ng/ml and body mass index, this result should be interpreted with caution, considering confidence intervals (RR 1.10 95% CI 0.37 to 1.83. We identified 4 high quality evidence that vitamin D levels and high physical activity required a direct relationship considering (four trials with 2,253) ; RR 0. (RR 0.0; 95% CI -0.15 to 0.15) (RR 0.59; 95% CI 0.43 to 0.75. Although the evidence available so far, from observational studies of medium quality, can be seen as showing a trend towards an association between sufficient serum levels of 25(OH)D and physical activity, this relationship has been shown. have a stimulating effect on vitamin D synthesis, the relationship of low body mass index with sufficient vitamin D levels is not based on solid evidence. We await results from ongoing studies to determine this effectiveness.
