Background: The importance of warm up procedures prior to athletic performance is well
established. A common component of such procedures is muscle stretching. There is
conflicting evidence regarding the effect of static stretching (SS) as part of warm up
procedures on knee joint position sense (KJPS) and the effect of dynamic stretching (DS) on
KJPS is currently unknown. The aim of this study was to determine the effect of dynamic and
static stretching as part warm up procedures on KJPS and knee extension and flexion
Methods: This study had a randomised cross-over design and ten healthy adults (20±1
years) attended 3 visits during which baseline KJPS, at target angles of 20° and 45°, and
knee extension and flexion strength tests were followed by 15 minutes of cycling and either a
rest period (CON), SS, or DS and repeat KJPS and strength tests. All participants performed
all conditions, one condition per visit.
Results: There were warm up x stretching type interactions for KJPS at 20° (p = 0.024) and
45° (p = 0.018), and knee flexion (p = 0.002) and extension (p < 0.001) strength. The SS and
DS improved KJPS but CON condition did not and SS decreased strength. No change in
strength was present for DS or CON.
Conclusions: Both SS and DS improve KJPS as part of pre-exercise warm up procedures.
However, the negative impact of SS on muscle strength limits the utility of SS before athletic
performance. If stretching is to be performed as part of a warm up, DS should be favoured
