Figure 1. The experimental set-up for the four interventions: control (CON), foam roller with rolling (FR_rolling), foam roller with static compression (FR_SC), and foam roller with dynamic movement (FR_DM). The intervention was set at 30 seconds. The CON condition was rest in the sitting position for 60 seconds. The FR_rolling condition were performed from proximal to distal and back to proximal of the dominant (preferred to kick a ball) knee extensors in 2 seconds. The FR_SC condition compressed the muscle belly of knee extensors. The FR_DM condition was knee flexion with the muscle belly of the knee extensors compressed. The measured parameters were knee flexion range of motion, pain pressure threshold, tissue hardness, and countermovement jump height.
