Стаття присвячена вивченню впливу навантаження на стан серцево-
судинної системи легкоатлетів і борців із різною тілобудовою. Результати
виконання функціональних проб показали, що всі спортсмени, не залежно від
особливостей їх фізичного розвитку, мали високий рівень адаптації системи
кровообігу до фізичних навантажень. Більшість виявлених ЕКГ-феноменів є
проявами морфо-функціональних адаптаційних змін серця легкоатлетів і
борців під впливом силового і аеробного фізичного навантаження. Статья посвящена изучению влияния нагрузки на состояние сердечно-
сосудистой системы легкоатлетов и борцов с разным телосложением.
Результаты функциональных проб показали, что все спортсмены,
независимо от особенностей их физического развития, имели высокий
уровень адаптации системы кровообращения к физическим нагрузкам.
Большинство выявленных ЭКГ-феноменов являются проявлениями морфо-
функциональных адаптационных изменений сердца легкоатлетов и борцов
под влиянием силовой и аэробной физической нагрузки. The article is devoted to studying the influence of load on the condition of
the cardiovascular system of athletes and wrestlers with different types of
physique. The results of the study showed that all athletes, regardless of their
physical development, had a high level of adaptation of the circulatory system to
physical stress. All athletes showed a normotonic type of hemodynamic reaction
during the execution functional test Letunova with a dosed load on endurance, as
evidenced by typical unidirectional changes in the heart rate and systolic blood
pressure towards their moderate increase and an adequate decrease in the level of
diastolic blood pressure immediately after stopping the test and сomplete recovery
of hemodynamic parameters within 1-2 minutes. According to the results of the
load test of Rufieu, it was established that all the wrestlers had a "good" level of
cardiac efficiency, but among the normostenics the index of the Rufieu was
smaller, which indicates a higher ability of their heart muscle to withstand highintensity
power loads, in contrast to the functional potential of heart of asthenics
and hypersthenics. In addition, morpho-functional adaptive changes in the heart of
athletes and wrestlers were investigated using their standard ECG. The most
common ECG phenomena of athletes are increased voltage in the chest leads and
peripheral reduced voltage of the ECG. Such ECG signs as the shortening of the
PQ interval and the incomplete blockade of the right leg of the branch Gissa were
equally represented on the ECG of the athletes of both groups. All other ECG
phenomena in athletes and wrestlers were determined in few athletes. The majority
of sports physicians, these ECG-phenomena are considered as a variant of the
norm, which do not require additional diagnostics. In favor of physiological
changes on the ECG of athletes, there is absence of pathological changes from the
side of the cardiovascular system when performing functional tests with dosed
physical activity, both among athletes and among wrestlers. |
