Little is known regarding the effects of a single stretch on range of motion (ROM) in athletes. This research compares changes in ROM in the hamstring and ankle following a single bout of either proprioceptive neuromuscular facilitation with myofascial release (PNFMR) or AquaStretch(TM) (A/S). Participants were females who achieved 150 min/week of moderate/vigorous physical activity (PA) (Age = 21.16, SD= ±2.01). Participants received both PNFMR and A/S on two separate occasions. ROM measures were evaluated at baseline and six time points following the stretch. Results indicated PNFMR improved ROM in right (p=.011) and left (p=.007) hamstrings. A/S improved ROM in right (p=.046) and left (p=.002) hamstrings and right (p=.014) and left (p=.002) dorsiflexion. Only A/S improvements lasted to 24h in right dorsiflexion (p=.004) and to 24h (p=.007) and 7d (p=.007) in left dorsiflexion. Significant improvements from a single stretch may assist in the prevention of injuries.
