We read the article by Al-Eisa et al1 entitled “Correlation between vitamin D levels and muscle fatigue risk factors based on physical activity in healthy older adults,” regarding an important subject – the association among vitamin D deficiency, physical activity, and muscle fatigue; the findings of this study indicate that increased physical activity is associated with higher vitamin D levels and less fatigue. We would like to comment on this well-designed and performed study.
