Characterization of physical exertion in the U-20 Futsal

Abstract

The evolution of the futsal has taken to increase of scientific production in this area, providing a better knowledge of this sport, consequently, a better trained athlete, able to attend the necessities of this modality. The purpose of this study was measuring the dislocation of young players during futsal soccer matches. Observing the subject researches it was noticed that there are studies which measured physical exertion according to its intensity, kind and volume of specific dislocation for tactical position in the playing-field. For the development of this research was used 6 futsal players until 20 years old. Through the video tape record was defined the specific step length of the athletes walking, jogging, running fast, walking backwards, jogging backwards and moving sideways. Afterwards the athletes was filmed individually in 4 matches and the distance covered for each player in every type of locomotion was calculated through the multiplication of number of steps during the game by the specific step length of the person. The total distance average covered by the athletes was 2,432.35 meters. Walking was the type of movement that occurred more frequently, having the athletes covered in average 75.01 meters distance every minute. In relation to the intensity predominated the low ones, followed by the medium ones and at last the high intensity. Observing the results could be noticed that the distance covered in the different patterns of the movement vary from one athlete to another, as well as the percentage of activities of high, medium and low intensity. The relation between activities of high and low intensity was in average 1 to 3. This results suggest that futsal characterizes as a sport that demands intermittent exertion, where the player must be able to covered distances over 3,483 meters.
