ИСПОЛЬЗОВАНИЕ СЕЛЕНА ДЛЯ ПОДДЕРЖАНИЯ РАБОТОСПОСОБНОСТИ У ЭЛИТНЫХ СПОРТСМЕНОВ
Аннотация
Цель. Целью данного исследования было изучение влияния селена на физическую работоспособность элитных спортсменов в течение контрольных и подготовительных тренировочных мезоциклов. Материалы и методы. В исследовании приняли участие 44 профессиональных легкоатлета в возрасте 19,9 ± 0,21 года. В контрольную группу вошли 20 человек. Спортсмены экспериментальной группы (12 спортсменов) принимали добавку с содержанием селена в дозе 50 мкг в сутки в течение 21 дня интенсивных тренировочных нагрузок, такое же количество спортсменов вошло в группу участников, не получавших добавку. Спортсменов контрольной группы обследовали однократно, а спортсменов экспериментальной группы и группы без добавки – дважды: в начале исследования и через 21 день интенсивных тренировок. В ходе исследования регистрировали частоту сердечных сокращений, измеряли артериальное давление, определяли параметры вариабельности сердечного ритма и оценивали общую физическую работоспособность с помощью теста PWC170. Результаты. Показатели теста PWC170 выросли в 1,22 раза (P < 0,05), индекс Mo – в 1,1 раза (P < 0,05), а ∆RR – в 1,44 (P = 0,03) раза. Зарегистрировали снижение индекса стресса в 1,72 раза (P = 0,01). Заключение. Прием селенсодержащей добавки способствовал поддержанию физической работоспособности и регуляции сердечного ритма у спортсменов высокой квалификации в течение контрольных и подготовительных тренировочных мезоциклов.
