Abstract

Background: Muscle stretching is often applied as a preparation for resistance training, however, the literature has diverged as to its response on muscular endurance strength. Objective: to show whether the intensity and time of muscle stretching modifies the resistance strength. Methods: The study included 30 healthy young males aged 22 ± 2.5 years, who had been practicing neuromuscular exercise for at least six months. Participants took a maximum load prediction test (MLPT) on the bench press and after one week returned to the draw and execution of the: Stretch Protocol (SP) - 60 seconds at maximum amplitude without assistance; Flexing Protocol (FP) - 60 seconds of stretching with external assistance; and Base Protocol (BP) - immediate exercise. All participants went through all protocols always performed on Mondays, performing the maximum repetitions with 70% of the load obtained in the MLPT. To compare the results of the different days of collection was used the ANOVA with TUKEY post-hoc. All analyzes adopted a value of p≤0.05 as significant. Results: BP showed significantly higher results than in SP and FP. There was no statistical difference between SP and FP. Conclusion: 60 seconds of passive muscle stretching causes a decrease in muscle resistance strength, regardless of its intensity.
