About this study
Official title: 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: a Randomized, Controlled, Cross-over Study
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
VFROther
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.
FROther
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Muscle tone
The muscle tone (Hz), as a biomechanical property of the knee flexors and extensors, will be assessed using the MyotonPro (Myoton AS, Tallinn, Estonia). The rectus femoris will be preferred as the primary extensor and the biceps femoris as the principal flexor for the assessment, due to their anatomical and functional centrality. To ensure accuracy, the probe will be applied perpendicularly in three successive increments, with automatic alerts for any deviation. The rectus femoris measurement will be taken at the midpoint between the anterior superior iliac spine and the medial patellar border, with the subject supine and a 20 cm roller under the knees. For the biceps femoris, the subject will be prone with an ankle pillow for relaxation, with measurements taken at the midpoint of the long head's longitudinal axis to ensure consistency. Each muscle will be measured twice in immediate succession, using the mean for analysis.
Measured: one week
Stiffness
The stiffness (N/m), as a biomechanical property of the knee flexors and extensors, will be assessed using the MyotonPro (Myoton AS, Tallinn, Estonia). The rectus femoris will be preferred as the primary extensor and the biceps femoris as the principal flexor for the assessment, due to their anatomical and functional centrality. To ensure accuracy, the probe will be applied perpendicularly in three successive increments, with automatic alerts for any deviation. The rectus femoris measurement will be taken at the midpoint between the anterior superior iliac spine and the medial patellar border, with the subject supine and a 20 cm roller under the knees.

Questions about this trial
What is this clinical trial studying?
A study testing VFR and FR in people with Self-Myofascial Release, run by Manisa Celal Bayar University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle tone (time frame: one week). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2026.
