| Summary: | Background: Vitamin D plays a crucial role in maintaining musculoskeletal health. A growing body of evidence links vitamin D deficiency with decreased muscle strength and suboptimal exercise performance in adults.
Aim: This review aims to synthesize existing research on the effects of vitamin D deficiency on muscle strength and exercise efficiency in adults, identifying the physiological mechanisms involved and discussing the potential clinical implications.
Materials and Methods: A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science databases. Studies included original research, systematic reviews, and meta-analyses published in English between 2000 and 2024. Keywords used included "vitamin D," "muscle strength," "exercise performance," "deficiency," and "adults."
Results: Most studies support a positive association between adequate vitamin D levels and improved muscle function. Deficiency is linked with reduced type II muscle fiber size, impaired neuromuscular function, and increased inflammation. Supplementation with vitamin D, particularly in individuals with vitamin D deficiency, often results in improved muscle strength and exercise performance, although findings vary by study design and population.
Conclusions: Vitamin D deficiency negatively affects muscle strength and exercise capacity in adults. Clinicians should consider monitoring and correcting vitamin D levels, particularly in populations at risk of deficiency. Future research should focus on identifying optimal dosing strategies and the long-term effects of supplementation.
