Vitamin D and human skeletal muscle

Area of Science:

• Sports Medicine
• Endocrinology
• Nutritional Science

Background:

• Vitamin D deficiency is a global health concern affecting bone health and linked to chronic diseases.
• While its role in bone health is established, vitamin D's impact on muscle function is less recognized in sports medicine.
• Historical observations and emerging research suggest a positive link between ultraviolet rays, vitamin D, and athletic performance.

Purpose of the Study:

• To review the current understanding of vitamin D's role in skeletal muscle tissue.
• To highlight the functional significance of vitamin D for athletes.
• To explore the potential impact of vitamin D deficiency on athletic performance and injury.

Main Methods:

• Literature review of cross-sectional and longitudinal studies.
• Examination of research on vitamin D receptor discovery in muscle tissue.
• Analysis of genomic and non-genomic roles of vitamin D in skeletal muscle.

Main Results:

• Evidence supports a functional role for vitamin D in muscle morphology and function.
• The discovery of the vitamin D receptor in muscle provides a mechanistic basis for its action.
• Vitamin D deficiency may negatively affect athletic performance and increase injury risk.

Conclusions:

• Vitamin D plays a significant role within skeletal muscle.
• Understanding vitamin D's impact is crucial for sports medicine and athletic optimization.
• Addressing vitamin D deficiency may enhance athletic performance and reduce injury incidence.
