Силовые тренировки значительно повышают уровень инсулиноподобного фактора роста-1 у женщин, ведущих сидячий образ жизни: рандомизированное контролируемое исследование

Цель исследования: определить влияние силовых тренировок и аэробных упражнений на уровень инсулиноподобного фактора роста-1 (ИФР-1) у женщин, ведущих сидячий образ жизни.

Материалы и методы: Тридцать три женщины, ведущие сидячий образ жизни, были случайным образом разделены на три группы: группа силовых тренировок (n = 11), группа аэробных тренировок (n = 11) и контрольная группа (n = 11). Участницы исследования были в возрасте от 18 до 26 лет. Сбор данных проводился в течение двух дней начиная со сбора информации о характеристиках испытуемых. Перед началом упражнений у испытуемых взяли кровь для предварительного анализа. Затем испытуемым было предложено размяться. После этого испытуемые выполняли физические упражнения в соответствии с их группой. После завершения упражнений были взяты образцы крови для повторного анализа.

Результаты: Данные показали, что уровень ИФР-1 был значимо повышен в группе силовых тренировок (p = 0,012).

Вывод: интенсивные силовые упражнения могут повысить уровень ИФР-1. Действие гормона роста опосредуется ИФР-1, который также необходим для контроля соматического роста и развития органов, включая мозг. Силовые тренировки можно рекомендовать в качестве альтернативных упражнений для людей, ведущих сидячий образ жизни, с целью улучшения когнитивных функций.
