BLOOD PRESSURE AND HEART RATE VARIABILITY AFTER AEROBIC AND WEIGHT EXERCISES PERFORMED IN THE SAME SESSION

Purpose: To verify the systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR) and heart rate variability (HRV) response after resistance and aerobic exercises in different combinations. Methods: Nine normotensive men performed in non-consecutive days a single session of aerobic exercise (cycle ergometer; 60% of VO2 peak; 50 min)plus resistance exercises (eight exercises; three sets; 10-15 reps; 60% of 1RM) and a single session of resistance exercises plus aerobic exercise. SBP, DBP, MAP, HR and HRV were evaluated at rest and at each 10 min (during 60 min) after exercises. Results: Difference between sessions has not been found. In the session which initiated with the aerobic exercise, SBP decreased in the total mean post-exercise period (resting = 121.3 +/- 3.9; post = 114.4 +/- 2.1 mmHg) while HR increased (resting = 75.8 +/- 4.3; post = 89.5 +/- 5.8 bpm). On the other hand, there was no difference in the DBP, MAP or HRV. Conclusion: The exercise sessions order does not alter cardiovascular and autonomic post-exercise response in normotensive subjects.
