Table 1.
Repeated measures quantified outcomes. Changes in range of motion (ROM), passive stiffness, and maximum dynamic passive torque (DPTmax) immediately before (pre), immediately after (0), and 15, 30, 45, 60, 75, and 90 minutes after no stretch or static stretch at 100%, 110%, and 120% intensity.
