Abstract
Aim: High-intensity resistance exercise leads to metabolic acidosis and muscle dysfunction. The patch method, by inducing respiratory alkalosis, may reduce these effects, but the evidence regarding its effect on resistance performance is conflicting. This study investigated the effect of recovery using a patch on squat and bench press performance in resistance-trained men.
Methods: In this study, 12 resistance-trained male students with a mean age of 22.41 years participated in three sessions 72 hours apart. In the first session, demographic data, one-repetition maximum of the chest press and squat were measured, and a weight-bearing protocol exercise was performed. In the second and third sessions, participants performed 3 sets of the chest press and squat at an intensity of 80% of one-repetition maximum to failure, and the number of repetitions was recorded. During the rest period between sets (5 minutes), participants breathed either normally (control) or at a rate of 60 breaths per minute (ventilation), and data were analyzed with a paired t-test.
Results: The results showed that recovery with the help of a barbell significantly (p≥0.05) increased (10.92% in the bench press and 11.42% in the squat) the average number of repetitions performed in the bench press (23.66 ± 3.65 barbell vs. 21.33 ± 3.93 normal) and squat (26.83 ± 4.82 barbell vs. 24.08 ± 4.27 normal).
Conclusion: Based on the findings of the present study, recovery between sets with the help of a treadmill may improve bench press and squat performance in resistance trained men.
