Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Low Intensity
The low-intensity group undergoes a strength training program using barbells, weights and dumbbells, consisting of 6 sets of 12 repetitions each, with an execution speed below 40% of the maximum velocity used in the one-repetition maximum
Low intensity
Low intensity group: participants will be requested to perform the following exercises: 1)squat, 2) rowing, 3)deadlift and 4)bench press. All exercises will be performed with low intensity (40% of the maximum velocity used in one-repetition maximum) and will be supervised by a researcher.
high intensity
The low-intensity group undergoes a strength training program using barbells, weights and dumbbells consisting of 6 sets of 6 repetitions each, with an execution speed equal to or greater than 80% of the maximum velocity used in the one-repetition maximum
high intensity
High intensity group: participants will be requested to perform the following exercises: 1)squat, 2)rowing, 3)deadlift and 4)bench press. All exercises will be performed with high intensity (80% of the maximum velocity used in one-repetition maximum) and will be supervised by a researcher.
