The present research involves 19 pupils of the 6–8th grades, going in for football extracurricular activities for 90 minutes three times a week, who have been examined here. The monitoring of schoolchildren’s adaptive abilities has been carried out at definite periods of the lessons differentiated into three types of orientation – moderate, average and competitive intensity. According to the values of superslow bioelectrical brain activity (omega-potential) and variability of heart rate, being the criteria of central nervous and cardiovascular system, the current functional states and urgent reactions of pupils, boys, aged 13–14, have been studied at the football lessons within the physical training process. There has been determined personal and group levels of functional reserves mobilization, characterizing the physiological “value” of children’s organism adaptation due to the amount of physical loading intended. It has been found out that training lessons with moderate and average intensity among the majority of pupils are accompanied with optimal shifts of registered indexes of central nervous and cardiovascular system. The physical loadings of high intensity conducted in the circumstances of increased motivation (competitions) are characterized by greater stability of physiological processes regulation mechanisms and by a relatively high rate of rehabilitation. It has been revealed that inadequate physical loadings in the process of learning-training lesson result in registered pupils sharp increase of tension index (in 5–8 times) and deep decrease of omega-potential (more than 50 %), which gives evidence of regulatory mechanisms of adaptation overstrain. One can assert that the use of omega-potential dynamics and heart rate variability data on various stages of educational process and at any particular lesson allows to obtain objective information about adaptive abilities of pupils doing sports and to implement control (correction) over physical training of schoolchildren. Prospects of the further researches consist in expanding the contingent of pupils by age and sex signs identifying features of the formation and development of Adaptive possibilities for sports, means and methods of physical education schoolchildren and athletes.
