Vitamin D and muscle trophicity

Area of Science:

• Endocrinology
• Muscle Physiology
• Nutritional Science

Background:

• Vitamin D deficiency is linked to decreased muscle mass and strength.
• Emerging research highlights vitamin D's role in muscle development and repair processes.

Purpose of the Study:

• To review recent scientific findings on vitamin D's role in skeletal muscle trophicity.
• To explore vitamin D's impact on muscle cell proliferation, differentiation, and metabolism.

Main Methods:

• Review of recent scientific literature and investigations.
• Analysis of studies examining vitamin D's effects on muscle cell behavior and function.

Main Results:

• Vitamin D deficiency correlates with reduced muscle mass and strength.
• Vitamin D influences skeletal muscle cell proliferation, differentiation, and metabolism, including protein synthesis and mitochondrial function.
• Recent studies indicate a genetic contribution of vitamin D to muscle functioning.

Conclusions:

• Vitamin D plays a significant role in maintaining muscle health, mass, and function.
• Its 'trophic' properties are particularly relevant for the elderly, athletes, and individuals with chronic diseases.
• Addressing vitamin D deficiency is important for preserving muscle function across various populations.
