Ethnic Variations in Muscle Mass and Strength: Evidence, Gaps, and Future Directions
Muscle strength and size vary widely among individuals and populations. This paper examines factors contributing to these differences with a focus on ethnic disparities. A literature-based synthesis was conducted using peer-reviewed studies examining differences in muscle physiology between ethnicities. While the literature shows that major differences across different ethnicities exist, the underlying causes remain poorly understood. Factors such as cultural diets as well as muscle quality are proposed as potential contributors. Socioeconomic status (SES) has also been considered, but contradictory findings suggest it is not a primary factor, suggesting deeper biological and cultural influences. These insights are relevant for developing equitable training, rehabilitation, and healthcare strategies tailored to diverse populations.
