Effect of warm-up on performance of football players

Title: The Effects of a warm-up on the performance of football players Objectives: The comparison of influence of two types of warm-up before and after a physical activity on performance of U19 football players. Testing of subsequent post-warm-up performance focused on acceleration, explosive power and agility. Methods: In this empirical-theoretical thesis, a total of twenty-four U19 football players, divided in two experimental groups, is tested. The players within each group undertook either a complete dynamic warm-up or a shorter warm-up without the dynamic component. The performance was tested after the warm-up utilizing four tests - an acceleration run test on 30 m, a standing long jump, a foul throw and a shuttle run. The same tests were conducted again after an interlaid physical activity. The same procedure was repeated after a week when the two groups swapped the warm-up methods. Statistical analyses were employed to evaluate the results. Results: The hypothesis 1, assuming a positive effect of a complete dynamic warm-up on the performance before the physical activity was on one hand supported in the acceleration run on 30 m and the foul throw. On the other hand, no distinctive advantage of a complete dynamic warm-up was observed for the standing long jump and the shuttle run. Hypothesis 2..
