CRITICAL VELOCITY VERIFICATION THROUGH FOUR VELOCITIES OF AMATEURS RUNNERS

Abstract

The search of new indexes capable to predict human performance is extremely interesting, once starting from these, it's possible to prescribe, in a more efficient way, a training program, besides favoring a more precise evaluation to the effects of the training. Objectives: To determine the time obtained in the distance of 500 meters, 1500 meters, 3000 meters e 5000 meters, and to verify through the relationship time/distance the possibility to find the critical velocity (Vcrit) between the four distances where the energetic systems utilization are distinct. Methods: Were selected to the study seventeen runners, who are experienced for running middle and long distances. The four distances were performed in a track of 200 meters with the aim to identify the critical velocity through the angular coefficient of the straight line of lineal regression between the respective times and distances: 1- 500 meters; 2- 1500 meters; 3- 3000 meters; 4- 5000 meters. Results: Were found a correlation between the distances 3 and 4. The critical velocity achieved it was of 20,02 ± 2,28 Km/h, 18,35 ± 2,14 Km/h, 16,46 ± 2,11 Km/h and 16,19 ± 1,99 Km/h, for the distances of 500 m, 1500 m, 3000 m e 5000 m, respectively. Conclusion: We can observe with this study that in field tests intended to determine the Vcrit we must take in consideration the energetic ways mobilization.
