Effect of physical activity and age on plasma copper, zinc, iron, and magnesium concentration in physically active healthy males

Abstract Objectives The concentration of nutritionally important minerals in circulation is under tight homeostatic control, however, physical activity and aging influence their body stores and nutritional requirement. The aim of this study was to evaluate the effect of both physical activity and age on plasma concentrations of copper, zinc, iron, and magnesium. Methods Stratified cluster sampling was used for selection of study participants (N = 360) belonging to three physical activity groups: sedentary, moderately active, and highly active on the basis of their physical activity levels as 1.53, 1.8, and 2.3, respectively. They were also divided into six different age groups (18–20, 21–25, 26–30, 31–35, 36–40, and 41–45 y). We assessed nutritional status by determining their body composition using bioelectrical impedance method and measuring intake levels. Fasting blood samples were taken to separate plasma for analysis of copper, zinc, magnesium, and iron. Results There was a major difference ( P Conclusion Physical activity-related energy expenditure and age play a remarkable role in deciphering the plasma mineral levels in the healthy individuals.
