Abstract
This study involved the application of static stretching exercises in warm-up part of soccer training with vibration stimulus (VSI), compared to an equivalent stretching exercise without applying vibration (SSI). For this purpose, all subjects, are in a randomized manner selected in two equal groups (SSI and VSI). Complete treatment for both groups lasted four weeks (3 x per week). VSI group has implemented an identical training as SSI group, with difference that all exercises performed on the platform (f = 40 Hz, A = 2 mm). Results of the combined analysis of variance, indicating that there is a statistically significant interaction (p<0.05) on variables to assess range of motion, in addition to the variable to assess range of motion in the position of plantar flexion (p = .079). Results of muscle function of lower limbs showed no differences between the study groups (p<0.05). The results of this study suggest that in chronic settings, static stretching with vibration have the potential to cause a substantial increase in range of motion, but without significant improvement of muscle function (jumping and sprinting).
