Checking of cardiovascular responses of people with normal blood pressure submitted to a single exercise session resisted with weights in different intensities
Abstract
We noticed that people with high blood pressure have sought to do exercises with weights more frequently; therefore, the research had as its aim to investigate thecardiovascular responses of people with normal blood pressure submitted to a single exercise session resisted with weights in different intensities. For such, 10 active volunteers with normal blood pressure, youngsters aged (22,0±0,1), weight (69,0±0,3 Kg), and BMI (22,0±0,1kg/m2). The tests were accomplished at a gym in Alto Tietê. A sharp session of ERW (Exercise resisted with Weights) at 40% and 70% of 1RM in the conventional way was done: 3 series of 12 repetitions with 1-minute intervals between the series and equipment. The following equipment was selected for the accomplishment of the exercises: Leg press: 45%, upright face-up, front pulley, shoulders development, upright screw, triceps pulley A (blood pressure) BP, (cardiac frequency) CF, and (double product) DP. They were simultaneously measured as they were static, and 5, 10, 15, 30, 45, and 60 minutes after exercise. Results shown there was a significant (post-exercise low blood pressure) (p< 0,05) with weight at 70% of 1RM when compared with values at 40% and when static, in systolic blood pressure (93 mmHg), diastolic (64 mmHg), and average (74 mmHg, with a single session of exercise resisted with weights in volunteers with normal blood pressure. The CF and the DP were normalised within resting conditions at the 10th minute and at the 5th minute after exercise respectively. The current study inferred that an exercise with at 70% of 1 RM causes a stronger after-exercise decrease in blood pressure compared to an exercise at 40% of 1 RM.
