Objective: to determine the functional state of sportsmen and prepathological state junior and middle-aged, exercise endurance. Material and methods: the ECG 50 athletes of Olympic Reserve School of Rostov-on-Don involved in cyclic sports (among them athletes of 32 people, 8 swimmers, 10 rowers), carried out at the planned depth medical examinations of athletes on the basis of the medical department in Olympic Reserve School of Rostov-on-Don predsorevnovatelny period. ECG was recorded in the company's Sshiller electrocardiograph 12 conventional leads to a state of rest and the muscle in the early recovery period after submaximal load PWC170 test.
Results: in the study of heart rate in athletes have been identified such as small ECG signs of arrhythmias and early repolarization syndrome alone, normalization that occurs under the influence of the load submaximal intensity, however, CCM swimmers 15-16 years of age after exercise persisted and deepened ECG signs of early repolarization in conjunction with cardiac arrhythmias and conduction atriventrikulyarnoy.
Conclusions: most athletes adolescents with adult category I, the young men from the CCM qualification, MS and athletes I mature MS involved in cyclic sports, revealed a positive effect of training sessions on the functionality of the heart, regulating its activities and electrogenesis. ECG changes swimmers 15-16 years of age, having qualified IMR regarded as signs of chronic heart surge.
