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.
