ABSTRACT
Purpose:
The present study aimed to compare the acute hormonal and metabolic response following a resistance training (RT) session with and without inter-set stretching.
Methods:
Overall, 13 men with minimum 1 year of experience with RT were randomly allocated to 2 groups: traditional RT group (TRT; n = 6; age: 22.5 ± 4.7 years; body weight: 83.1 kg ± 5.7 kg; height: 179.8 ± 6.9 cm; BMI: 25.73 ± 1.17 kg/m2) and stretching RT group (SRT; n = 7; age: 23.4 ± 4.3 years; body weight: 82.3 ± 11.7 kg; height: 177.7 ± 11.0 cm; BMI: 26.02 ± 2.5 kg/m2). The RT protocol consisted of 6 bench press sets to failure at 80% of 8 repetitions maximum, with a 1-minute rest interval between sets. During the rest interval, the TRT group remained resting, while the SRT group was submitted to shoulder anterior chain muscles stretching.
Results:
The results revealed a higher increase in lactate (32%) and total leukocytes (17%) immediately following exercise in the SRT group as compared with the TRT group (p < 0.05). An increase in total testosterone and cortisol was observed in both groups, without differences between them (p > 0.05). There was a progressive decrease in the total number of repetitions completed along sets, without differences between groups.
Conclusions:
The use of agonist stretching between sets increases the acute metabolic response during an RT session, which could be useful to intensify RT in trained participants.
