Respostas de frequência cardíaca, pressão arterial e duplo-produto ao exercício contra-resistência: uma revisão da literatura

Abstract

The purpose of this study was to review the literature about chronic and acute responses of heart rate, blood pressure, and rate pressure pro- duct associated with resistive exercises. The higher heart rate acute res- ponses seem to be directly related to the number of repetitions perfor- med. The effect of regular training over heart rate chronic responses is higher in aerobic programs, but long-term strength training can also elicit rest heart rate reductions. Systolic and diastolic blood pressure values are more related to the exercise intensity than to its overall nature (strength training or aerobic). However, blood pressure acute responses to strength training seem not to increase rest blood pressure values. Some findings suggest that strength training can reduce blood pressure at rest and during sub-maximal exercises. The rate pressure product seems to be lower during strength training than in aerobic exercises, which can be explained by the duration of both activities, since resistive exercises are associated with a less execution time. Finally, some studies indicate that variables different from the wor- kload-number of repetition relationship can influence the acute cardio- vascular responses during strength training. This fact should be taken into account in the exercise prescription, particularly for subjects with high risk for cardiovascular morbid occurrences.
