The main purpose of this study was to compare the acute effects of static and dynamic stretching
in the warm-up, on hamstring flexibility using a reliable set-up for measurement.
Static and dynamic flexibility was measured using five modifications of the Straight Leg Raise
(SLR) test to measure hip flexion range of motion (ROM). In the first part of the study (n = 33)
hamstring flexibility was measured using a Static-passive, Static-active, Dynamic-supine and
Dynamic-standing tests. The results of this study were used to calculate reliability statistics and
to compare the various static and dynamic flexibility tests. There was a significant difference
between Static-passive (SPH) and the Dynamic-supine (DSUH) tests (p less than .05).
This was followed by an intervention study (n = 12) where participants were randomly assigned
to three intervention treatments of 225 seconds on separate days: No stretching (Treatment I),
Static stretching (Treatment 2) and Dynamic stretching (Treatment 3) in a cross-over study
design. Static stretching had no impact on dynamic hamstring flexibility; however, dynamic
stretching improved dynamic flexibility while simultaneously increasing static flexibility. This
has implications for the specificity of stretching in sport.
