Abstract
Previous research has shown that vibration foam rolling (VFR) on damaged muscle can result in improvements in muscle soreness and range of motion (ROM). Furthermore, static compression via VFR (i.e., VFR without rolling) can increase the ROM and decrease the muscle stiffness of non-damaged muscle. Therefore, it is likely that static compression via VFR on eccentrically damaged muscle can mitigate muscle soreness and the decrease in ROM, and the decrease in muscle strength. The purpose of this study was to investigate the acute effects of a 90 s bout of VFR applied as a static compression on an eccentrically damaged quadriceps muscle, measuring ROM, muscle soreness, muscle strength, and jump performance. This study was a single-arm repeated measure design. Study participants were sedentary healthy male volunteers (n = 14, 20.4 ± 0.8 years) who had not performed habitual exercise activities or any regular resistance training for at least 6 months before the experiment. All participants performed a bout of eccentric exercise of the knee extensors with the dominant leg and then received a 90 s bout of static compression via VFR of the quadriceps 48 h after the eccentric exercise. The knee flexion ROM, muscle soreness at palpation, and countermovement jump height were measured before the eccentric exercise (baseline), before (pre-intervention) and after the VFR intervention (post-intervention), and 48 h after the eccentric exercise. The results showed that the static compression via VFR significantly (p < 0.05) improved the knee flexion ROM (6.5 ± 4.8%, d = 0.76), muscle soreness at palpation (−10.7 ± 8.6 mm, d = −0.68), and countermovement jump height (15.6 ± 16.0%, d = 0.49). Therefore, it can be concluded that static compression via VFR can improve muscle soreness and function.
Highlights
Vibration foam rolling (VFR) is a self-care technique involving the simultaneous use of foam rolling (FR) and vibration therapy, which shows the potential to have a favorable warm-up effect in increasing range of motion (ROM) [1] or performance [2] compared to conventional FR
ROM, MVC-ISO torque, maximal voluntary concentric contraction (MVC-CON) torque, and countermovement jump (CMJ) height values were significantly lower than the baseline values
The results showed that static compression via vibration foam rolling (VFR) could induce recovery from the decreases in knee flexion ROM, CMJ height, and increases in muscle soreness and tissue hardness
Summary
Vibration foam rolling (VFR) is a self-care technique involving the simultaneous use of foam rolling (FR) and vibration therapy, which shows the potential to have a favorable warm-up effect in increasing range of motion (ROM) [1] or performance [2] compared to conventional FR. Recent studies have shown that VFR can increase range of motion (ROM) [1,3,4] and decrease muscle stiffness [3,5,6]. It has been reported that VFR can increase muscle strength and jump performance [2,3], the changes in these variables were not significant [5,6]. The additional vibration stimulus of VFR is likely the reason why VFR has been found to be more effective in increasing the ROM of a joint [1]. Preparing for performance tasks [2], compared to normal FR.
