Abstract

The purpose of this review is to examine vitamin D in the context of sport nutrition and its potential role in optimizing athletic performance. Vitamin D receptors (VDR) and vitamin D response elements (VDREs) are located in almost every tissue within the human body including skeletal muscle. The hormonally-active form of vitamin D, 1,25-dihydroxyvitamin D, has been shown to play critical roles in the human body and regulates over 900 gene variants. Based on the literature presented, it is plausible that vitamin D levels above the normal reference range (up to 100 nmol/L) might increase skeletal muscle function, decrease recovery time from training, increase both force and power production, and increase testosterone production, each of which could potentiate athletic performance. Therefore, maintaining higher levels of vitamin D could prove beneficial for athletic performance. Despite this situation, large portions of athletic populations are vitamin D deficient. Currently, the research is inconclusive with regards to the optimal intake of vitamin D, the specific forms of vitamin D one should ingest, and the distinct nutrient-nutrient interactions of vitamin D with vitamin K that affect arterial calcification and hypervitaminosis. Furthermore, it is possible that dosages exceeding the recommendations for vitamin D (i.e. dosages up to 4000-5000 IU/day), in combination with 50 to 1000 mcg/day of vitamin K1 and K2 could aid athletic performance. This review will investigate these topics, and specifically their relevance to athletic performance.

  • Vitamin D supplementation could influence VO2max values given that CYP enzymes that activate vitamin D3 have proteins with heme groups, which could potentially increase the affinity of oxygen binding to hemoglobin.

    “For that reason, vitamin D supplementation could influence VO2max values given that CYP enzymes that activate vitamin D3 have proteins with heme groups, which could potentially increase the affinity of oxygen binding to hemoglobin [5].”

    From Influence of Sunlight and Oral D3 Supplementation on Serum 25(OH)D Concentration and Exercise Performance in Elite Soccer Players (2020) · cites this paper as [5]

    The “Maximal oxygen uptake” section proposes that vitamin D3-activating CYP enzymes contain heme proteins and could potentially affect oxygen’s binding affinity to hemoglobin. It also reports a supplementation trial with increased VO2max. The paper does not specify that the proposed mechanism would increase binding affinity, as the citing sentence claims. (LLM, conf=0.88)

  • 1.25(OH)2D is involved in muscular development and function, control of hormonal systems and control of inflammation and tissue and muscle damage.

    “1.25(OH)2D, as a biological active form of 25(OH)D, is involved in muscular development and function, control of hormonal systems and control of inflammation and tissue and muscle damage [5].”
  • Emerging data suggest that vitamin D supplementation aimed at achieving serum concentrations above the reference value may augment increases in skeletal muscle mass, function, decrease recovery time from exercise, and increase both power and force production in older adults.

    “In addition to restoring deficient levels, data are also emerging to suggest that vitamin D supplementation aimed at achieving serum concentrations above the reference value may augment increases in skeletal muscle mass, function, decrease recovery time from exercise, and increase both power and force production in older adults [284,297,298].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
