ACUTE EFFECT OF DIFFERENT STATIC STRETCHING ROUTINES ON COUNTERMOVEMENT JUMP

ABSTRACT

The aim of the study was to observe the effects of two stretching routines, with the same total volume, on countermovement jump height (JH) and range of motion (ROM) of knee flexion (KF) and extension (KE). Ten subjects were randomly assigned to either a fractionated stretching (ST-10) with 3 sets of 10 s, or continuous routine (ST-30), with a single 30 s set, and a non-experimental control condition (CC). The JH was obtained immediately after interventions using a contact matt. ROM was measured by photogrammetry pre and post intervention. A repeated measures ANOVA followed by Bonferroni's post hoc test showed a significant increase in KF (P=0.004) and KE (P=0.001) ROM post ST-30 and a significant JH increase after ST-10 compared to CC (P=0.005). It was concluded that continuous static stretching routines may increase ROM without altering JH, while the fractionated routine with the same volume, may not alter ROM although improving JH.
