Rate-pressure product’s behavior in different body positions practicing resistance dynamic exercises

Through the rate-pressure product it is possible to predict, in an indirect way, as oxygen the myocardium can consume. The present study verifi ed the heart rate, the blood pressure and the rate-pressure product, during two exercises against-resistance of inferior parts (squats), which only varied to each other in the performer's body position (standing or in dorsal decubitus), in order to evaluate the amount of cardiovascular stress that an exercise could generate in relation to the another. Thirty healthy and trai- ned individuals were appraised (30 ± 6 years), which accomplished in each one of the two apparels one set of 10 RM. The data were collected during the rest and the last two repetitions of the set of 10 RM of each apparel. Whole the collected variables were presented according to the descriptive statistics. Already the values of the rate-pressure product obtained during the execution of the exercises, were appraised for the T-test of Student with a signifi cant index of p<0.05 and the found result was very signifi cant (p <0.001). This way it can be said that the standing squats generates a more signifi cant stress in the cardiovascular system than squats accomplished in dorsal decubitus.
