RUMBLEROLLER - Firmer Black racquet and the chance of injuryFOAM ROLLERS MERELY COMPRESS MUSCLE When you roll on a conventional foam roller, a compressive force is generated. The amount of compression depends on the size of the contact patch between the roller and your skin. For a typical 6" diameter foam roller, that contact patch is large, so the amount of compression is small and the effect on deeper tissues is very limited. To counter this limitation, athletes often progress to smaller and harder rollers
