Abstract

As you know, the physical working capacity of football players is manifested in the form of two integral properties of the body, different in physiological nature - aerobic and anaerobic abilities. It is these abilities that largely determine the achievement of high results in modern football. The assessment of RF will be objective only when comparing the result of the work done with its physiological cost. Unfortunately, this provision is often ignored in the practice of training football players. So, often the time of work and its volume is the only criterion in the assessment. Note that the criteria for assessing KSS, developed for athletes, cannot be used for football players. The point is that the specificity of motor activity forms the specificity of autonomic reactions.In football, the most important role for ensuring the performance of muscle work is played by the oxygen consumption and transport system, or, as it is often called, the cardiorespiratory system. Diagnostics of the KSS response to testing loads is the main task in assessing the RF of football players in laboratory conditions. [2]
