Cardiological and Psychophysiological Reaction of Schoolchildren with Different Types of Central Gemodynamics to Prolonged Physical Activity

Abstract: 
The present paper considers the issues of optimizing the construction of a lesson of recreational physical education by differentiating the load on the basis of data on the physical fitness of students. It also touches upon the question of the response of stress-realizing systems of schoolchildren to the physical work performed. The aim of the study is to investigate the cardiologic and psychophysiologic response of schoolchildren with different types of central hemodynamics to prolonged physical workload. Methodology. Cardiologic and psychophysiologic parameters of 74 male students aged 12–13 years were studied. The sample included only practically healthy individuals without severe chronic and acute diseases. All students were divided into three groups by physical fitness (based on the results of the PWC170 test) and three subgroups by the type of central hemodynamics (according to N.N. Savitsky: hypokinetic, eukinetic, hyperkinetic). Heart rate and attention response to running exercise of different durations with excellent rest intervals and response were evaluated. Conclusion. The results obtained indicate different reactions of schoolchildren with different types of central hemodynamics to prolonged physical load: the hypokinetic type had stable heart rate values during the load, better recovery after the load and the least decrease in attention according to the B. Bourdon test. The hyperkinetic type, on the contrary, had unstable dynamics of heart rate during exercise, the lowest rate of heart rate recovery and a pronounced decrease in attention. The eukinetic type had average performance on all tests. The results of the study can be used as a tool to optimize the methodology of the educational process through the most effective dosing of the load.
