Abstract: | The effects of magnesium supplementation on blood parameters were studied during a period of 4 wk in adult tae-kwon-do athletes
at rest and exhaustion. Thirty healthy subjects of ages ranging in age from 18 to 22 yr were included in the study. The subjects
were separated into three groups, as follows: Group 1 consisted of subjects who did not train receiving 10 mg/kg/d magnesium.
Group 2 included subjects equally supplemented with magnesium and exercising 90–120 min/d for 5 d/wk. Group 3 were subject
to the same exercise regime but did not receive magnesium supplements. The leukocyte count (WBC) was significantly higher
in groups 1 and 2 than in the subjects who did not receive any supplements (p < 0.05). There were no significant differences in the WBC of the two groups under magnesium supplementation. The erythrocyte,
hemoglobin, and trombocyte levels were significantly increased in all groups (p < 0.05), but the hematocrit levels did not show any differences between the groups although they were increased after supplementation
and exercise. These results suggest that magnesium supplementation positively influences the performance of training athletes
by increasing erythrocyte and hemoglobin levels. |
