The purpose of this investigation was to examine the acute effects of two hip flexor stretching techniques on hip extension ROM, knee joint position sense (JPS) and dynamic balance performance (DB). Thirty-six healthy college age students (25 males, 11 females; mean=22.39 years) who exhibited hip flexor tightness participated in this study. Hip extension ROM, knee JPS and DB were tested pre- and post-stretching using digital inclinometer, iPod touch and the Y-balance kit, respectively. Subjects were randomly divided into dynamic (DS), and hold-relax proprioceptive neuromuscular facilitation (HR-PNF) groups. Three-way mixed analysis of variance (ANOVA) was utilized to explore if an interaction between the groups (DS vs. HR-PNF), time (pre-and post) and (side of hip, knee angle and direction or reach) existed over the experiment as specified by hip extension ROM, knee JPS and dynamic balance measurements, respectively. There was a significant effect of time on hip extension ROM in both stretching groups (pp=0.004) favoring HR-PNF over DS. There was a non-significant effect of time on mean knee JPS replication error in both groups. In dynamic balance measurement, there was a significant main effect of time on the Y-balance test’s mean distance (pp
