Description

The purpose was to determine the effects of prior stretching – static, dynamic, and proprioceptive neuromuscular facilitation (PNF) – on performance which included the standing long jump and agility tests. Twelve collegiate female athletes (soccer) completed one control (no prior stretching) and three experimental sessions which included a 6 minute stretching protocol followed by performance testing. All sessions were randomly assigned to avoid an ordered effect. The independent variables were static, dynamic, and PNF stretching. The dependent variables were performance in the standing long jump and agility drills comprised of a 3 cone drill and a 20 yard shuttle run. The sessions were completed with pairs of subjects competing against each other for the longest jump and fastest time. It was hypothesized that (1) static stretching will decrease performance; (2) dynamic stretching will increase performance; and (3) PNF stretching will exert a split effect with no effect on agility but a decrease in the long jump. Pilot data demonstrated that all forms of stretching increased flexibility acutely. Other data collected thus far supports the superiority of dynamic stretching and indicates static stretching contributes to performance decrements. Data continues to be collected and complete data will be presented.
