Objective of the study was to substantiate the content of the in-depth control over speed abilities of the 14-15 year-old football players and thus determine players' individual speed ability profiles. Methods and structure of the study. The laboratory test toolkit included: a psychophysiological test used to obtain the central nervous system functionality rates. The pedagogical test toolkit included: 30m run from standing start, flying ball strike, standing long jump and football T-test - speed run with changing directions. Sampled for the study conducted in March 2019 were 24 football players of 2004 of birth (body length - 170.83±6.13 cm, body weight - 59.85±10.67 kg, maximum oxygen consumption - 51.93±5.52 ml/kg/min). The athletes and their parents were informed in detail on the ongoing research goals, objectives and methods and gave a written consent for the study and publication of the data obtained. The work was carried out in accordance with the WMA Declaration of Helsinki. The laboratory tests were conducted in the laboratory "Technologies of Sports Rehabilitation and Selection" of the Common Use Center of Ural State University, field tests - on the grass pitch of the Specialized Children and Youth Sports School of the Olympic Reserve "VIZ". Study results and conclusions. During the study, we formed 6 groups of indicators that fully characterized the speed ability components as required by the specifics of football. The testing revealed the mean group indicators and enabled to form individual speed ability profiles. The control over the football players' speed abilities requires differentiation in conditions of the scientific sports laboratory. The in-depth control over the speed abilities of each football player in the laboratory and field conditions may help determine the leading and trailing links in the structure of their speed skills.
