Brief Summary

This study aims to compare the acute effects of low- and high-frequency vibration foam rolling on flexibility, dynamic balance, and vertical jump in young male recreational athletes. Fourteen athletes will be included in this study, planned as a randomized controlled cross-over study. All athletes wil be completed three interventions: 1) low-frequency vibration foam rolling (LFVFR), 2) high-frequency vibration foam rolling (HFVFR), 3) rest control. Pre- and post-test assessment will be included flexibilty, assessed with the sit-and-reach test; dynamic balance, assessed with the Y balance test; and vertical jump, assessed with the vertical jump test.

Study Groups

HFVFR Group

Athletes will be performed three sets of HFVFR for 30 s, with a 30 s break between each set and exercise. The rolling frequency will be standardized using a metronome set at 60 beats per minute. Athletes will be instructed to roll at a velocity of two metronome beats for each rolling direction. Intensity of pressure will be controlled with a target rating of 7 of 10 on a Numerical Rating Scale (0 = no discomfort and 10 = maximum discomfort) during HFVFR intervention. The target muscle groups and/or body sides will be anterior thigh, posterior thigh, posterior calf, iliotibial-band, and gluteals (buttocks).During HFVFR, the vibrator booster will be set to a frequency of 67 hz, which is within the optimal frequency range (12 to 90 hz) to influence musculoskeletal system, and an amplitude of 1.95 mm.
