Static stretching did not result in any significant performance decrements compared to the No-Stretch protocol. In fact, the Static stretching protocol resulted in significantly quicker maximum speed performance compared to No-Stretch. Therefore, the recommendation that static stretching should be omitted from warm-ups may be inappropriate, with little consideration for injury and performance aspects related to static stretching, aside from absolute force potential. Dynamic stretching resulted in the best scores in all but the vertical jump test. Therefore, the use of dynamic stretching in warmups is probably optimal for high speed soccer performance.
