Figure 2. For the foam roller with static compression (FR_SC) and foam roller with dynamic movement (FR_DM) conditions, participants were instructed to remain in the plank position and place the foam roller only at the midpoint of the knee extensors of the dominant leg (A). The FR_SC condition was instructed to remain in that position (A) for 30 seconds, pressing the trunk against the foam roller as far as it could tolerate. The FR_DM condition was instructed to hold compression and mobilize the knee to maximum flexion in 1 second (B) and again in 1 second to maximum extension (A). A metronome (60bpm) was used for control.
