Abstract: This study aimed to examine effects of acute and chronic submaximal
exercise on plasma renin and aldosterone levels in football players. Seven apparently healthy, male footballer subjects took part in the study. The
subjects were exercised on ergometric bicycles for 20-min at 75% of Max
VO_{2}, 3 days a week for 4 weeks. Blood samples were
collected on 4 occasions: before the exercise, immediately after the exercise,
as well as 2 hours and 24 hours after the exercise. Plasma renin and
aldosterone levels (RIA) were measured. Exercise significantly increased plasma
renin and aldosterone levels of the athletes before and after the exercise
(p < 0.05). The levels at the 2nd hour following exercise
dropped significantly in comparison to those immediately after the exercise
(p< 0.05). Plasma values one day after the exercise were
significantly lower than those after the 2nd hour (p < 0.05). Consequently, acute and 4-week chronic submaximal exercise have
significant effects on plasma renin and aldosterone levels in football players
(p< 0.05).
