Analysis of open pull exercise with and without the pre-exhaustion method in physiological stress parameters
Abstract
Strength training (FT) is usually prescribed to promote increased strength, power, endurance, and muscle hypertrophy. These adaptations can be modulated by manipulating the training variables, such as number of sets and repetitions, load intensity, training volume, choice and order of the exercises. The order of the exercises refers to the sequence in which they are performed in a training session, which seems to directly influence the number of repetitions and consequently the total volume of work. The objective of this study was to compare the double product, heart rate, and systolic and diastolic blood pressure before and after the pulley exercise with open footprint with and without the pre-exhaustion method. The study was characterized as a cross - sectional descriptive of an exploratory nature, with quantitative analysis, the sample was composed of 8 female subjects practicing bodybuilding at least six months without interruption. For the evaluation of heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) and double product (DP) were used Polarimeter FT4 model, Hospital Aneroid Premium Sphygmomanometer. The data were analyzed in the Statistical Package for the Social Science (SPSS) 20.0 for Windows program. Regarding the comparison of hemodynamic variables HR, SBP, DBP and DP pre, during and post session with and without the pre-exhaustion method, a significant difference of some values was observed. Without the pre-exhaustion we had significant differences between the means of rest for the first, second and third series of HR, SBP, DBP and DP, with the same test but using the pre-exhaustion method, we obtained differences of averages comparing the values Of resting with 1st, 2nd and 3rd series. However, when comparing the values with and without pre-exhaustion, there was no significant difference. Therefore, the pre-exhaustion method should not be prescribed based on HR, PD, SBP and DBP, suggesting the development of more in-depth studies on the subject.
