Summary

This study aims to compare the immediate effects of vibration and non-vibration foam rolling on the biomechanical and viscoelastic properties of knee flexor and extensor muscles in young male recreational athletes. Fourteen athletes will be included in this study, planned as a randomized controlled cross-over study. All athletes will complete three interventions: 1) vibration foam rolling (VFR), 2) non-vibration foam rolling (FR), and 3) rest control. Pre- and post-test assessment will include the biomechanical and viscoelastic properties of knee flexor and extensor muscles, assessed with the MyotonPro.

Conditions

• Self-Myofascial Release

Interventions

Type	Name	Description
OTHER	VFR	Athletes will be performed three sets of VFR 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 VFR intervention. The target muscle groups will be the anterior and posterior thigh. During VFR, the vibrator booster will be set to a frequency of 48 hz, which is within the optimal frequency range (12 to 90 hz) to influence the musculoskeletal system, and an amplitude of 1.95 mm.
OTHER	FR	Athletes will be performed three sets of FR 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 FR intervention. The target muscle groups will be the anterior and posterior thigh. The FR will be conducted using the same vibration foam rolling device, but with the vibration mode deactivated. This ensures that the physical dimensions and material properties of the roller remain constant across conditions, with the only variable being the presence or absence of mechanical vibration.
