Immediate effects of high- vs. low-frequency vibration foam rolling on flexibility, dynamic balance, and vertical...

This study aimed to examine and compare the immediate effects of high- (HF-) and low-frequency (LF-) vibration foam rolling (VFR) on flexibility, dynamic balance, and vertical jump performance.

Fourteen young male recreational athletes (mean age: 21.78 ± 1.02 years) were included in the study. Using a crossover, random allocation design, all athletes completed three conditions: HF-VFR, LF-VFR, and control conditions. Pre- and post-test assessment included flexibility, assessed with the sit-and-reach test; dynamic balance, assessed with the Y balance test; and vertical jump, assessed with the Performanz JumpR.

Both HF-VFR and LF-VFR increased flexibility and dynamic balance without affecting vertical jump performance (p < 0.001, p < 0.001, respectively). HF-VFR was more effective than LF-VFR for improving flexibility and dynamic balance (p < 0.001, p < 0.001, respectively).

Strength and conditioning coaches should strongly consider integrating HF-VFR into their programming to effectively boost athletes' flexibility and dynamic balance, particularly given its superior efficacy over lower frequencies and no negative impact on jump performance.
