“…A variety of stretching methods have been reported to increase range of movement (RoM) (2). Range of movement has been shown to increase with both static and proprioceptive neuromuscular facilitation (PNF) stretching regimens (13,17,18,20,19,22,25,27,30); however, there is debate about which method is the most effective (14,18). Many of the studies have focused exclusively upon RoM and not on the effect of changing RoM on running mechanics.…”
