Цель. Определение структурно-функциональных характеристик миокарда у молодых людей с различным уровнем физической активности (ФА).

Материал и методы

Материал и методы. В исследование включено 108 молодых людей без заболеваний сердечно-сосудистой системы. 72 человека являлись профессиональными спортсменами на выносливость (группа С) и 36 не занимались спортом (группа НеС). Оценивались антропометрические данные. Проводилась трансторакальная эхокардиография (ЭхоКГ) и оценка продольной, радиальной и циркулярной деформации левого желудочка (ЛЖ), а также скручивание ЛЖ. Уровень ФА у НеС определялся с помощью "Короткого международного опросника для определения уровня ФА — IPAQ (International Physical Activity Questionnaire).

Результаты

Результаты. Уровень ФА <600 MET-мин/нед. имели 22,3%, умеренный (от 600 до 1500 MET-мин/нед.) — 41,7% и высокий (3000 MET- мин/нед.) — 36% обследованных в подгруппах неактивные, умеренно активные и высоко активные, соответственно. Уровень ежедневных физических нагрузок группы С составлял ~15000 MET-мин/нед. У НеС не наблюдалось статистически достоверных различий показателей ЭхоКГ в подгруппах с разным уровнем ФА. Выявлены статистически значимые различия с группой С. Диастолическая функция ЛЖ была в пределах нормы во всех подгруппах. Показатель E/A (соотношение пиков Е и А трансмитрального кровотока) был выше в под- группах с большей ФА (максимальный в подгруппе С). Статистически значимые различия наблюдались между подгруппами неактивные (p=0,027) и спортсмены/умеренно активные (p=0,017). Показатели продольной, радиальной и циркулярной деформации не различались у С и НеС и соответствовали нормальным значениям.

Заключение

Заключение. У молодых людей без известных заболеваний сердечно-сосудистой системы в диапазонах ФА от крайне низкого до рекомендуемого ВОЗ, структурно-функциональные характеристики миокарда не выходили за пределы возрастной нормы и достоверно отличались от показателей профессиональных спортсменов. У профессиональных спортсменов показатели так- же оставались в пределах возрастной нормы. Показатели деформации миокарда находились в пределах нормы у всех обследованных.

Aim

Aim. To determine the structural and functional characteristics of the myocardium in young people with different levels of physical activity (PA).

Material and methods

Material and methods. The study included 108 young people without cardiovascular diseases. Seventy-two people were professional endurance athletes (Group A) and 36 were non-athletes (Group non-A). Anthropometric data were evaluated. Transthoracic echocardiography and assessment of left ventricular (LV) longitudinal, radial and circumferential strain, as well as LV twisting, were performed. PA level in non-A group was determined using International Physical Activity Questionnaire (IPAQ).

Results

Results. PA level <600 MET-min/week was revealed in 22,3% of participants, moderate PA (from 600 to 1500 MET-min/week) — in 41,7%, and high (3000 MET-min/week) — in 36% of participants of inactive, moderately active and highly active subgroups, respectively. Group A daily PA level was ~15000 MET-min/week. In non-A group, there were no significant differences in echocardiographic parameters in subgroups with different PA levels. Significant differences with group A were revealed. LV diastolic function was within the normal range in all subgroups. The E/A ratio was higher in subgroups with higher PA (maximum in subgroup A). Significant differences were observed between inactive (p=0,027) and athletes/moderately active (p=0,017) subgroups. Longitudinal, radial and circular strain characteristics did not differ in A and non-A groups and were within normal range.

Conclusion

Conclusion. In young people without cardiovascular diseases with PA ranges from extremely low to those recommended by WHO, the structural and functional myocardial characteristics were within age normal range and significantly differed from those of professional athletes. In professional athletes, these parameters also remained within the age normal range. Myocardial strain characteristics were within the normal range in all participants
