Improvements in Acute Explosive Power without a Subsequent Decrease in the Range of Motion of Passive Hip-Flexion Muscles in Taekwondo Players Using Foam Rollers
Background: Foam rolling (FR) has been developed as a popular intervention, however the acute effect of muscular and range of motion (ROM) function using a FR is unknown in young taekwondo players.
Objective: This study examined the acute effects of multiple (lower extremity and back part of the body) FR exercises on joint ROM and vertical jump performance in taekwondo athletes.
Methods: Nineteen (age: 13.21 ± 0.85 years) black-belt taekwondo athletes (nmale = 13; nfemale = 6), volunteered to participate of this study. Anthropometric measurements, Passive Straight-Leg Raise Test (PSLR) on each limb and vertical jump tests were performed on the first measurement day. In the second day, following a common warm-up model, participants performed FR exercises on five areas (erector spinae, iliotibial band, hamstrings, quadriceps, and calves) for three minutes (30 seconds/1 set for each area). The tests were administered to all participants again by swapping over on the third day. A Two-Way and Three-Way ANOVA Repeated Measures tests were performed.
Results: It was not observed any significant interaction between the three factors (time, side, or gender) and PSLR-ROM degrees of dominant and non-dominant legs (p>0.05). There were observed significant differences between the pre-and post-test measurements in the vertical jump height (+13.02%) and jump power (+5.23%) performance after FR exercises. Conclusion: Multiple FR exercises did not acute affect PSLR-ROM in taekwondo athletes. FR exercises may be effective within warm-up protocols and seems to be an efficient strategy to promote acute improvements in vertical jump performance in a short time period.
