Acute effects of different warm-ups strategies on the performance of maximum repetitions in bench press in young adult men

Abstract

To evaluate the acute effects of different warm-ups strategies on the performance of maximum repetitions in bench press in young adult men, 15 men (26 ± 5 years old; body mass: 78 ± 6 kg; height: 172 ± 7 cm) were underwent to the maximum strength test (1RM) in bench press exercise and after 20 minutes a new test performed external overload control 70%1RM (CON) concentric to mechanical failure. The other sessions consisted of five separate warm-ups models, randomized, being: 1) strength resistance (RF): 15 reps at 40% 1RM; 2) static stretching (AE): used the static method with two 20-second series for each position, which were applied in the pectorals, deltoids and triceps; 3) aerobic exercise (AE): 5 min at 50%VO2_max on a treadmill and 4) (EA+AE); for the group the same exercises of EA and EA groups were conducted. After the specific warm-up was given 1 min recovery interval and it was made the maximum repetitions test with 70% 1RM. The results of this study demonstrate that the yield in the implementation of the bench press exercise showed significant differences between the following warm-ups strategies: CON x AE (p=0.0247), CON X EA (p=0.0003) and COM X EA + AE (p=0.0166), only warm-up using 40% 1RM (RF), did not show significant differences when compared to the control group (p = 0.3639). In conclusion, our data demonstrate that different warm-ups models impacted positively muscle performance in young-adult men, increasing the performance of the maximum repetitions test in the bench press, without, however, to differentiate each other.
