The heavy loads offered in training often carry a disruption of the adaptive capabilities of the athlete's body. Using the method of analysis of heart rate variability, allows you to make a full selection, rationally build a training regime, monitor the functional state, identify maladaptation and overtraining of athletes. The purpose of our study is to study the regulatory mechanisms and adaptive capabilities of the cardiovascular system of football players depending on age. 104 football players of different ages took part in the study (8-11 years old; 12-15 years old; 16-21 years old). To assess the functional state ofthe regulatory mechanisms of the cardiovascular system, we used the method of variational heart rate monitoring using the hardware and software complex "Varikard 2.51". The individual typological features of heart rate regulation depending on age are revealed. Long-term, systematic football practice, enhances the influence of the autonomous circuit of heart rate regulation. At the same time, not taking into account the regulatory mechanisms of the cardiovascular system, entails a breakdown of the adaptive capabilities of the body, which manifested itself in athletes (16-21 years old) of the fourth type of regulation
