Acute Effects of High- vs. Low-frequency Vibration Foam Rolling

Acute Effects of High- vs. Low-frequency Vibration Foam Rolling on Flexibility, Dynamic Balance and Vertical Jump in Young Male Recreational Athletes: a Randomized Controlled Cross-over Study Design

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: Control Group; No intervention will be applied to the control group.
Active Comparator: 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Flexibility	Flexibility will be assessed with the sit-and-reach test using an adjustable sit-and-reach bench (Adjustable Sit-and-Reach Flexibility Tester, Lafayette Instrument Company, Lafayette IN, USA). The sit-and-reach test is a valid and reliable method used to assess flexibility in many studies. First, the sit-and-reach bench placed on the mat will be fixed to the wall, and the players will be asked to place the soles of their feet on the sit-reach bench with their knees completely straight on the mat. Then, after one trial, players will be asked to reach forward as far as possible three times without bending their knees, and the average of the three assessments will be used for analysis.	two weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Dynamic balance	Dynamic balance will be assessed with the Y balance test. Before the assessment, the players will be performed three trials each with 30-second rest intervals for the dominant extremity, and after the trials, the players will be given a five-minute recovery period. During the assessment after the recovery process, to ensure standardization, the players will be asked to position their dominant extremity at the centre of the junction of the measuring tapes, lie on the measuring tape with their non-dominant extremity, extending as far as possible in the anterior, posterolateral, and posteromedial directions, and touch the furthest point they could reach with their toes. This procedure will be performed by players three times with 30-second rest intervals. The greater reach distance for each direction will be calculated with the formula [(reaching distance/lower extremity length) x 100 = percentage of the maximum reaching distance)], and will be normalised with the extremity length.	two weeks
Vertical jump	Vertical jump will be assessed with the Performanz JumpR, a valid and reliable device for assessing different jump performances.This device measures jump height based on the individual's flight time using the equation (jump height= 980.6653(flight time/1000.0)2/8). It also calculates anaerobic power using the individual's weight, flight time, and contact time using the equation (anaerobic power=weight x [9.813(flight time/2000,000)/(contact time/1000)]). For each jump, subjects will be instructed to jump as high as possible and keep their hands on their hips. There will be 1 minute of rest between jumps. All athletes will be received instructions to maximize their jump height and were verbally encouraged to exert maximum effort during all jump trials. The average of the three assessments will be used for analysis.	two weeks
