Abstract

This study aims to mathematically model short-term races of athletes and people who do not play sports, in order to raise the time equation of the two runners. This is an observational case study of a quantitative nature with the participation of a sedentary individual and an athlete of the gaucho futsal gold series, both practitioners of short-term races. A Sony film camera and the Sony Vegas 8.0 program were used for the analysis. Also, two series of 10 and 20 meter runs of each participant were filmed and analyzed. From this, the derivatives of the curves were calculated, verifying the athlete's complete performance throughout the race course. Thus, it was possible to model the performance of short-term test participants using a first principles method. The results indicate that the performance of the participants is similar due to the fact that the person who does not practice sports has aptitude for short-term races. It is concluded that for the athlete, in the 10m race, the athlete's deceleration demonstrates that the modeling is correct, since the negative acceleration indicates that he has decreased his speed. In the 20m race, it is observed that the speed as a function of time always increases and we always find a positive acceleration.
