The effects of one session of roller massage on recovery from exercise-induced muscle damage: A randomized controlled trial
36 men were asked to perform eccentric actions of the elbow flexors and placed into one of 3 recovery groups (roller, sham, control). They found a single session of roller massage applied on elbow flexors had no effect on recovery of MIVC, muscle swelling, ROM and DOMS.
TL;DR Roller massages do not improve recovery
