BACKGROUND: The purpose of this study was to compare the acute effects of different stretching types on sprint performance in taekwondo practitioners.
METHODS: Twelve male taekwondo practitioners performed stretching exercises using different types (ballistic, proprioceptive neuromuscular facilitation (PNF), static stretching) in a random order at three-day intervals; there was also a control condition involving no stretching exercises. The subjects performed 2 maximal 20m sprints (with 10m split times also recorded) with a recovery period of 1 minute immediately post stretching and at 5, 10, 15 and 20 minutes after stretching. They also performed these sprints before doing the stretching exercises.
RESULTS: The study results showed that sprint times significantly increased after static stretching (10m pre = 1.84±0.07 sec, 10m post = 1.89±0.08 sec; 20m pre = 3.33±0.19 sec, 20m post= 3.38±0.2 sec), PNF stretching (10m pre = 1.84±0.07 sec, 10m post = 1.89±0.08 sec; 20m pre = 3.33±0.19 sec, 20m post = 3.38±0.20 sec) and ballistic stretching (pre = 1.84±0.08 sec, post = 1.86±0.07 sec; 20m pre = 3.33±0.20 sec, 20m post = 3.35±0.21 sec) (p<0.05). In the static stretching condition, 10m and 20m sprint performance had fully returned to normal at 15 minutes after stretching. In the PNF stretching condition, 20m sprint performance returned to normal levels at 15 minutes after stretching, while 10m performance took 20 minutes to recover fully. In the ballistic stretching method, both 10m and 20m sprint performances had fully recovered at 5 minutes after stretching.
CONCLUSIONS: It is therefore concluded that the acute effects of static, PNF and ballistic stretching may negatively affect sprint performance, although sprint performance is less affected after ballistic stretching than after the other stretching types. Therefore, it is not advisable to perform PNF or static stretching immediately before sprint performance.
