Acute reply of the cardiac frequency in exercises against-resisted

Abstract

Objective: To verify the acute answers of the cardiac frequency front the exercises against-resisted in different stipulated overloads. Methods: 6 individuals had been evaluated men between 15 and 21 years, healthy, presented IMC inside of the normal values, exercises against-resisted practitioners more than the six months. All had executed the exercises supine straight in Smith and bilaterally bench extension under the following percentages of maximum load: 80-89%, 70-79% and 50-59% respectively in a period of three days. In each maximum load band and each exercise, it was registered acute cardiac frequency. Results: It was identified that the individuals that had executed the exercises with loads above of its corporal weight (in the band of 80-89% of the maximum load), had presented registered minor cardiac frequency. One also perceived that the arithmetic average of the cardiac frequency in both exercises was lesser in the percentile greater of maximum load, and the average greater, in the percentile minor of the maximum load. Conclusion: The study it indicates that the load use of high intensity (80-89%) registers in average a lesser acute cardiac frequency of that intermediate loads (70-79%) and light (50-59%). Another conclusive data disclose that loads exercised above of the corporal weight, in the 80-89% band, indicate minor cardiac frequency. Being thus, a relation of the cardiac frequency with the systolic arterial pressure (double product), what it represents a cardiovascular impact during the effort, could be manipulated in the lapsing of the training.
