Özet

This study was performed to assess how 4 weeks of magnesium supplementation and exercise affect the free and total plasma testosterone levels of sportsmen practicing tae kwon do and sedentary controls at rest and after exhaustion. The testosterone levels were determined at four different periods: resting before supplementation, exhaustion before supplementation, resting after supplementation, and exhaustion after supplementation in three study groups, which are as follows: Group 1-sedentary controls supplemented with 10 mg magnesium per kilogram body weight. Group 2-tae kwon do athletes practicing 90-120 min/day supplemented with 10 mg magnesium per kilogram body weight. Group 3-tae kwon do athletes practicing 90-120 min/day receiving no magnesium supplements. The free plasma testosterone levels increased at exhaustion before and after supplementation compared to resting levels. Exercise also increased testosterone levels relative to sedentary subjects. Similar increases were observed for total testosterone. Our results show that supplementation with magnesium increases free and total testosterone values in sedentary and in athletes. The increases are higher in those who exercise than in sedentary individuals.

Abstract

 

 

This study was performed to assess how 4 weeks of magnesium supplementation

and exercise affect the free and total plasma testosterone levels of sportsmen practicing tae

kwon do and sedentary controls at rest and after exhaustion. The testosterone levels were

determined at four different periods: resting before supplementation, exhaustion before

supplementation, resting after supplementation, and exhaustion after supplementation in three

study groups, which are as follows: Group 1—sedentary controls supplemented with 10 mg

magnesium per kilogram body weight. Group 2—tae kwon do athletes practicing 90-

120 min/day supplemented with 10 mg magnesium per kilogram body weight. Group 3—tae

kwon do athletes practicing 90-120 min/day receiving no magnesium supplements. The free

plasma testosterone levels increased at exhaustion before and after supplementation

compared to resting levels. Exercise also increased testosterone levels relative to sedentary

subjects. Similar increases were observed for total testosterone. Our results show that

supplementation with magnesium increases free and total testosterone values in sedentary

and in athletes. The increases are higher in those who exercise than in sedentary individuals.
