The purpose of this study was to evaluate the acute effect of two commonly used static stretches on hip internal rotation passive range of motion (HIR-PROM). Participants (n=30, 15 male, 15 female; 22±1.8 yrs.; 173.5±8.5cm; 73.8±12.7 kg) were randomly assigned (with gender controlled) to one of three groups: control (C), figure 4 stretch (F4), and modified lunge stretch (ML). Pre and post-test HIR-PROM was measured on each participant's non-dominant hip (28 left, 2 right). HIR-PROM was measured from the prone position; the knee was flexed to 90° and the hip was passively internally rotated. After the pretest, each participant completed a 10 minute warm-up on a cycle ergometer. Upon completion of the warm-up the two stretching groups (F4, ML) completed the respective stretching protocol while the control group rested on a table. A mixed model factorial ANOVA was used to analyze main effects (group, time) and if a significant interaction occurred. There was no interaction or group main effect (p>0.05), however, there was a time main effect regardless of group assignment (F1,27=33.151, p
