Description | The objection of this research was to compare the acute effect of the application of static and dynamic stretching on running economy at constant speeds (8, 10, 12 km/h) on the treadmill. We hypothesized that acutely after the application of dynamic stretching, the level of running economy (tested as VO2 at constant speeds) will be better than after static stretching. The results indicate that there is no statistically significant difference (p <0.05, p = 0.62 at v = 8 km/h, p = 0.25 at v = 10 km/h; p = 0.14 at v = 12 km/h) in the average running economy after the application of static and dynamic stretching in the investigated group of people (men, n = 8, mean age = 23.4 years). On the other hand, it is evident that after the application of static stretching, the average values are lower than after the application of dynamic stretching (by 0.61 at a speed of 8 km/h, by 1.44 at 10 km/h, and by 1.83 ml/kg/min at a speed of 12 km/h, respectively). We can only speculate about logical explanations of these results. One possibility may be the early morning time, during which the research was conducted. Stiff muscles may be more optimally prepared for the test by static than by dynamic stretching. The results may have also been influenced by the statistical error of the device (VO2 at 0.1%). These findings can be considered as important with regard to the implementation of the initial phase of training units and immediate preparation of runners for a race. However, we are aware that this problem must be studied in bigger complexity and with a larger sample of tested subjects. |
