Цель. Изучить электрокардиографические особенности спортсменов в раз-ные периоды тренировочно-соревновательного процесса в зависимости от вида спорта, интенсивности и типа тренировочных нагрузок. Материал и методы. Обследовано 136 спортсменов мужского пола. Квали-фицированные спортсмены 116 чел. (группы спортивного совершенствования и высшего спортивного мастерства, возраст 22,07±4,10 года, спортивный стаж 5-15 лет) разделены на группы: I -борьба (n=30), II -лыжные гонки, биатлон (n=27), III -пауэрлифтинг (n=33), IV -волейбол (n=26). Группа V -контроль (n=20), возраст 17,95±1,55 года, спортивный стаж не превышал 3 года. Методы исследования: электрокардиография (ЭКГ), холтеровское мони-торирование ЭКГ (ХМЭКГ), эхокардиография (ЭхоКГ), велоэргометрия (ВЭМ). Статистические методы. Результаты. В подготовительном периоде тренировочно-соревнователь-ного процесса изменения ЭКГ, включая нарушения ритма сердца (НРС), выявлены у 93 из 136, при этом у 86 (63,2%) квалифицированных спортсме-нов и у 7 (5,1%) контрольной группы (р=0,00001), в соревновательном пери-оде -у 104 (76,5%) и у 8 (5,9%) (р=0,00001), соответственно. Частота изме-нений ЭКГ у квалифицированных спортсменов в подготовительном периоде составила 116 случаев, в соревновательном 165 (p<0,05). В соревнователь-ном периоде наблюдалось увеличение не только общего числа спортсменов с НРС, но нарастание случаев синусовой брадикардии (p=0,0321), блокад ножек пучка Гиса (p=0,0455), нарушений процессов реполяризации (p=0,0034) и других изменений, в том числе сочетанных. У 15 спортсменов впервые выявлены НРС, требующие углубленного обследования (выражен-ная брадикардия, желудочковая экстрасистолия (ЖЭ), двухпучковые бло-кады, феномен WPW, выраженные нарушения процессов реполяризации миокарда). Заключение. С ростом спортивного мастерства увеличивается число зареги-стрированных изменений ЭКГ и случаев НРС, что требует дополнительного динамического электрокардиографического контроля спортсменов в про-цессе интенсивных тренировок соревновательного периода. Aim. To investigate on the electrocardiographic specifics of sportsmen at various stages of training and competition processes according to the sport type, intensity and training load type. Material and methods. Totally, 136 male sportsmen assessed. Qualified sportsmen 116 persons (groups of improvement and mastery, age 22,07±4,10 y. o., in-sport time 5-15 years) were selected to the groups: I -wrestling (n=30), II -ski racing, biathlon (n=27), III -powerlifting (n=33),

Training specialists of water transport at maritime University presents a complex of knowledge and skills. They are necessary for the specialists in order to fulfill their professional duties. Apart from special subjects an important stage of training becomes professional-applied physical training. Its complexes are formed from different kinds of sport or during going in for professional-applied kinds of sport and provide professionally important qualities development, which define during professiograms creation according to each specialty. During water transport specialists’ professiograms analysis it is seen that the general professionally important qualities are vestibular apparatus steadiness and statokinetic resistance. These qualities help specialists of water transport realize their job duties during pitching. One of the kinds of sport, the effectiveness of which depends on statokinetic resistance, is shooting sports. Shooting sports is a separate kind of sport, but as a kind of sport it is included into the complex of marine all-round competitions. Marine all-round competitions are professional-applied kind of sport for the specialists of water transport. They provide necessary professionally important qualities development. Shooting sports is the means of the following things development: statokinetic resistance, the ability to focus attention, psycho-emotional resistance. It is important during extreme situations. The conclusion, received as a result of scientific works analysis, helps to define the place of this kind of sport in the training diagram of marine all-round athletes, for getting the effect of positive transfers in the training process.

Aim. To determine the early predictive factors of cardiovascular changes in professional athletes, depending on the type and intensity of physical activity.Material and methods. A total of 136 male athletes were examined. Of these, 116 were professional athletes (age, 22,07±4,1 years) as follows: freestyle wrestling, judo (n=30), cross-country skiing, biathlon (n=27), powerlifting (n=33), volleyball (n=26). Control group included 20 athletes (age, 17,95±1,5 years) with a history of training less than 3 years. All participants underwent electrocardiography (ECG), echocardiography, cycle ergometry (CE) with assessment of physical performance at a heart rate of 170 bpm (PWC170) and maximum oxygen consumption (MOC). When creating predictive models of early cardiovascular changes, we used logistic regression, stepwise regression and Wald statistics. Differences were considered significant at p<0,05.Results. Predictive models of logistic regression using ROC analysis showed high sensitivity and specificity, a high percentage of correct predictions using data from echocardiography — 86,8%, CE — 80,9%, ECG and other indicators — 83,1%. A stepwise algorithm was used to select prognostic factors determining early cardiovascular changes in young athletes, depending on the stage of sports training, the intensity and type of dynamic and/or static exercise: left ventricular posterior wall thickness (p=0,008), left ventricular mass (p=0,001), stroke volume (p=0,002), end-systolic volume (p=0,001), PWC170 (p=0,025), MOC (p=0,003), recovery time of heart rate (HR) (p=0,029) and blood pressure (p=0,032) after submaximal exercise on a cycle ergometer, body mass index (p=0,029), heart rate (p=0,034), office systolic blood pressure (p=0,009), intraventricular (bundle) block (p=0,046), left ventricular repolarization abnormalities (p=0,010), mild cardiac connective tissue anomalies (p=0,035).Conclusion. The early prognostic factors established by the logistic regression affect the characteristics and risk of cardiovascular changes in each group of young athletes. This demonstrates the need to develop individual medical support programs, further monitoring, evaluation, correction and prevention of identified disorders, taking into account the type of sports, intensity and exercise.
