ОЦЕНКА ПОРОГОВ НЕЙРОМЫШЕЧНОГО УТОМЛЕНИЯ У ПОДРОСТКОВ-БЕГУНОВ НА КОРОТКИЕ ДИСТАНЦИИ
Аннотация
Цель. Нейромышечное утомление определяет результативность в беге на короткие дистанции, особенно среди спортсменов подросткового возраста. Целью настоящего исследования является оценка влияния 8-недельной программы нейромышечной тренировки на пороги утомления и их влияние на результативность в беге на короткие дистанции. Материалы и методы. В исследовании приняли участие 36 бегунов на короткие дистанции в возрасте 15–17 лет, обучающиеся в трех разных академиях города Лахора. Тест на бег на 40 метров проводили с использованием лазерной системы хронометража Brower Timing Systems с последующей электромиографической оценкой vastus lateralis и biceps femoris во время максимальных спринтерских попыток. Субъективную оценку утомляемости регистрировали с использованием шкалы воспринимаемого напряжения Борга (Rating of Perceived Exertion, RPE) с диапазоном 6–20 баллов. Результаты. Зарегистрированы значимые улучшения результативности в беге на 10 м (p = 0,012) и 40 м (p = 0,003), что выражалось в сокращении времени прохождения этих дистанций после исследования. Отмечено увеличение среднеквадратичной амплитуды мышц vastus lateralis (p = 0,008) и biceps femoris (p = 0,021) по данным ЭМГ-анализа, что свидетельствует об улучшении нейромышечной активации. Кроме того, зарегистрировано значимое (p < 0,05) снижение оценки воспринимаемого напряжения, свидетельствующее о повышении устойчивости к утомлению. Заключение. Нейромышечная тренировка повышает пороги утомления у подростков-бегунов на короткие дистанции за счет отсрочки наступления утомления. Последующие исследования могут быть направлены на изучение долгосрочных адаптаций при участии спортсменок для большей обобщаемости и применимости результатов.
