The purpose of the present study was to investigate the relationship between sympathoadrenergic and hemodynamic responses to exaustive acute exercise. Plasma hearth rate (HR), systolic and diastolic blood pressure (SBP, DBP), plasma norepinephrine (NE) and epinephrine (E) were misured in 23 male athletes before and after an 1 minute exaustive exercise on cycle ergometer. NE, E, SBP and HR levels significantly increased in response to exercise, while no change in DBP was found. NE and E variations were positively correlated with SBP and negatively with DBP changes. Results od the present stusy showed that cardiovascular responses to exaustive exercise is associated with an increased sympathoadrenergic activity.

Abstract
The purpose of the present study was to investigate the relationship between sympathoadrenergic and hemodynamic responses to exaustive acute exercise. Plasma hearth rate (HR), systolic and diastolic blood pressure (SBP, DBP), plasma norepinephrine (NE) and epinephrine (E) were misured in 23 male athletes before and after an 1 minute exaustive exercise on cycle ergometer. NE, E, SBP and HR levels significantly increased in response to exercise, while no change in DBP was found. NE and E variations were positively correlated with SBP and negatively with DBP changes. Results od the present stusy showed that cardiovascular responses to exaustive exercise is associated with an increased sympathoadrenergic activity.
