The Affect of Acute Static, Dynamic or No Stretching on Agility Performance

 Despite the plethora of literature regarding the effects of stretching on strength, power, and force production, there is very limited research available on the effects of stretching on agility as a component of athletic performance. Static stretching (SS) has shown decreases in many areas including strength, anaerobic power, and sprinting time. Dynamic stretching (DS) has shown increases in anaerobic power and decreases in sprinting time. A common factor in many athletic activities is the ability to explosively change movement velocity or mode, which is by nature, the definition of agility. What is unknown is whether the type of stretching performed prior to completing an agility activity effects performance time.

 

PURPOSE: The purpose of this study was to determine the effect of static and dynamic stretching on performance time of a sport agility test.

METHODS: Sixty male subjects consisting of collegiate (n=18) and recreational (n=42) basketball athletes volunteered for the study. Subjects were randomly assigned to one of 3 intervention groups: SS, DS, or no stretching (NS). All groups completed a 10 minute warm-up jog followed by a 3 minute rest. The SS and DS groups then completed an 8.5 minute stretching intervention. Next, all subjects completed 3 trials of the 505 agility test with 2-5 minutes rest between each trial; mean time was recorded. A 2-way analysis of variance (Stretch group, athlete category, group x athlete interaction) was used to determine statistical significance (p<0.05). A Tukey post-hoc test was performed to determine differences between groups.
