Currently, football is one of the most popular disciplines in the world. In the country of four-time World Champions, it is the most popular sport in which millions of fans and players are engaged. The German Bundesliga belongs to the Top 4 football leagues in Europe. Constant development of the discipline improves the training process. Shaping and developing selected motor skills seems to be necessary in modern training. In previous studies, many researchers emphasize the importance of motion speed in football. Nevertheless, the research conducted on a group of players of one German team in the 2017/2018 season raised some doubts. Therefore, the study attempts to expand research and determine the relationship between start speed and running speed and the effectiveness of football games of German teams. The research subject was 83 footballers from German clubs Berliner TSC and BSC Eintracht Sudring Berlin. The results of studies carried out in Berlin in the 2017/2018 and 2018/2019 seasons were analyzed. The take-off speed in 5 m race, 20 m run speed was measured, and the players' effectiveness during the game was modified using the competent referee method. The test results were statistically processed in the Statistica 13.3 program. Descriptive statistics (X), minimum (min), maximum (max) and standard deviations (SD) statistics were performed and a correlation coefficient was determined. In studies on an increased research group, no significant statistical relationship was found between motion speed and the effectiveness of German players' game.
