简要总结
This study aims to determine the acute effects of high and low-intensity strength training on cardiac autonomic control in hypertensive subjects
详细描述
The present study aims to determine the cardiovascular response in hypertensive individuals between 30 and 60 years old to one session of high and low intensity strength training.
Participants will undergo a low-intensity strength training including squats, barbell rows, deadlifts and chest presses with a load dynamic of 12 repetitions for 6 sets at an execution speed of less than 55 % of your maximum weight. This is followed by a one-week washout period. Subsequently, high intensity strength training is performed with the same exercises but with a load of 6 repetitions for 6 series at an intensity greater than 80% of the maximum repetition speed. The order of the sessions will be random.
After each session, blood pressure will be recorded for 24 hours using a holter monitor, which will report pressures during both day and night
The results obtained will be determined by the differences in the before and after values. Consequently, the behavior of the following variables: 1) heart rate variability, 2) blood pressure and 3) heart rate will determine the final results of this research.
The entire study will be carried out at the Catholic University of Maule, in its Kinesiology laboratory.
