Abstract:

Physiological variables are intended to measure physical stress, discomfort or fatigue associated with a particular activity or training method. This study aims to know the acute responses of changes in physiological variables through Rest-Pause and Drop-Set methods. It was selected 5 male individuals, aged between 22 and 27 years old, who had practiced resistance training for at least one year. For the data analysis, the SPSS software was used performing descriptive statistics analysis (mean, standard deviation and frequency). The mean was used for individual and group purposes. The results showed that the heart rate at the end of the execution in both methods presented a great increase in relation to the resting one, however satisfactory changes occurred during the series. Blood glucose in both methods showed positive results compared to pre-exercise blood glucose, however in the drop-set method the mean glycemia had a greater reduction. The accumulation of post-exercise blood lactate reached high results, however, there is a slight difference in post-exercise lactate mean where rest-pause method was superior to drop-set method, the subjective perception of effort in both methods gradually changed over the series, reaching an average effort from intense to almost exhaustive. We conclude that both methods presented great physiological alterations when comparing the pre-exercise variables, having a small difference in the analyzed variables, thus identifying which one can cause more metabolic and physiological stress in the individual, facilitating the process to obtain hypertrophy.
