PURPOSE: To compare the immediate effects of a hold-relax proprioceptive neuromuscular
facilitation stretching (HR-PNF) versus static stretch (SS) on hamstring flexibility in healthy …

This study compares the effects of 3 common stretching techniques on the length of the
hamstring muscle group during a 4-week training program. Subjects were 19 young adults …

Few studies have reported on the amount of acute changes in flexibility of the hamstrings
resulting from stretching prior to activity, and no studies of this nature have focused on an …
