Aim: The aim of the study was to investigate the impact of the moderate (60% of the 15RM) versus high (80% of the 15RM) workload of resistance exercise on cardiovascular response and postexercise hypotension (PEH) among elderly hypertensive women.
Methods: Twenty-one volunteers performed two sessions with the upper limbs (with moderate and light workload) and another two sessions with the lower limbs. Heart rate and the Adult OMNI Perceived Exertion Scale for Resistance Exercise (OMNI-RES) were measured during the exercises. The arterial blood pressure was measured before, during and at 50 minutes into the recovery period.
Results: The protocols with intensity at 80% of 15RM resulted in a perceived exertion at the end of each set, which was statistically higher than procedures with intensity at 60% of 15RM. This same phenomenon occurred both for upper- and lower-limb exercises. The double product was significantly higher in the high-intensity session than in the low-intensity session; however, none exceeded 17000 bpm x mmHg. The high-workload exercises promoted consistently higher PEH, in the lower and upper-limb exercises, respectively. The delta was -24 mmHg versus -14 mmHg for the systolic arterial pressure and -14 mmHg versus -9 mmHg for the diastolic arterial pressure.
Conclusion: The conclusion was that resistance exercises with high workload result in greater PEH without elevating the double product significantly.
