2019) Quadriceps foam rolling and rolling massage increases hip flexion and extension passive range-of-motion. Journal of Bodywork and Movement Therapies, 23 (3).
ABSTRACT
34Increases in joint range-of-motion may be beneficial for improving performance and 35 reducing injury risk. This study investigated the effects of different self-massage volumes and 36 modalities on passive hip range-of-motion. Twenty-five recreationally resistance-trained men 37 performed four experimental protocols using a counterbalanced, randomized, and within-38 subjects design; foam rolling (FR) or roller massage (RM) for 60 or 120-second. Passive hip 39 flexion and extension range-of-motion were measured in a counterbalanced and randomized 40 order via manual goniometry before self-massage (baseline) and immediately, 10-, 20-, and 41 30-minute following each self-massage intervention. Following FR or RM of quadriceps, 42 there was an increase in hip flexion range-of-motion at Post-0 (FR: ∆=19.28º; RM: 43 ∆=14.96º), Post-10 (FR: ∆=13.03º; RM: ∆=10.40º), and Post-20 (FR: ∆= 6.00º; RM: 44 ∆=4.64º) for all protocols, but not exceed the minimum detectable change at Post-10 for 45 RM60 and RM120, and Post-20 for FR60, FR120, RM60, and RM120. Similarly, hip 46 extension range-of-motion increase at Post-0 (FR: ∆=8.56º; RM: ∆=6.56º), Post-10 (FR: 47 ∆=4.64º; RM: ∆=3.92º), and Post-20 (FR: ∆=2.80º; RM: ∆=1.92º), but not exceed the 48 minimum detectable change at Post-10 for FR60, RM60, and RM120, and Post-20 for FR60, 49 FR120, RM60, and RM120. In conclusion, both FR and RM increased hip range-of-motion 50 but larger volumes (120-vs. 60-second) and FR produced the greatest increases. These 51 findings have implications for self-massage prescription and implementation, in both 52 rehabilitation and athletic populations. 53
