Effect of exhausting exercise and calcium supplementation on potassium, magnesium, copper, zinc and calcium levels in Athletes

Present study was performed to determine four week calcium supplementation and athleticism exercise on plasma potassium, calcium, magnesium, cupper and zinc levels in resting and exhaustion. Research was carried out on 30 healthy male people. Group 1; Exercise, Group 2; Exercise + Calcium supplementation, Group 3; Sedentary+Calcium supplemented. All elements levels increased by exhausting exercise [P<0.05]. Plasma K and Ca levels increased in exercise group after supplementation [P<0.05]. Ca levels increased in exercise + supplemented group [P<0.05]. This increase was much more in group three [P<0.05]. Plasma Cu levels increased by Ca supplementation in sedentary [P<0.05]. Exhausting exercise increased Zn levels in sedentary after supplementation [P<0.05]. The results of present study show that calcium supplementation for 4 week does not have clear affect on potassium and Mg. However, calcium levels were increased by supplementation and Cu after the supplementation. It was also exhausting exercise that caused increase in all parameters

effect of magnesium supplementation on glucose and insulin levels of Tae-Kwan-Do sportsmen and sedentary subjects

This study was performed to determine how the magnesium supplementation for a 4-week period affects the glucose and insulin levels at rest and at exhaustion in sportsmen. This is a 4 week study performed on 30 healthy male subjects varying between 18-22 ages. Subjects were separated into 3 groups. 1st group; group supplemented with magnesium, 2nd group; Magnesium supplementations +exercise group, 3rd group; training group. Glucose and insulin parameters of the groups were measured 4 times; at rest and exhaustion in the beginning of the research and at rest and exhaustion after the end of 4 weeks application period. Glucose levels in exhaustion measurements both before and after the supplementation significantly increased compared to resting levels [p < 0.05]. Significant difference was determined in the glucose values of 1st and 2nd groups supplemented with magnesium in comparison to their first measurements [p < 0.05]. Insulin values a decrease in all of the 3 groups occurred with exercise both before and after the supplementation [p < 0.05]. Magnesium supplementation has an important effect on glucose levels whereas it has no effect on insulin levels
