The use of technology and computer science is transforming the field of sports. Combined with the explosion of data science and machine learning, models can be built to evaluate an athlete's performance and extract useful information. This diploma thesis uses a data recording system,the REMEDES, in the field of football. Using REMEDES, a testing battery is developed, experimental measurements are performed on athletes and with the use of data science, a system of evaluation and direct comparison is created, as well as a model of prediction of player’s position based on performance.
