По-моему из нижеследующего следует сделать вывод о том, что гипервентиляция уместна только в малоповторном режиме тренинга. Необходимо отметить, что журнал Muscle & Fitness предназачен в основном для культуристов, а не силовиков.

Цитата из журнала Muscle & Fitness №1 2010, с.10:

Тяжёлоатлеты и пауэрлифтеры, чтобы завести себя перед рекордной попыткой, практикуют гипервентиляцию - частые вдохи-выдохи. Не вздумайте последовать их примеру! Как показали последние научные исследования, подобный приём вреден. Согласно ожиданиям атлетов, гипервентиляция должна повысить содержание кислорода в крови. При этом количество "вредного" углекислого газа, наоборот, понизится. Кровь, обогащённая кислородом, поступит в мозг и вызовет его активацию. Это как раз и поможет развить уникально мощное психическое усилие.
Однако на практике всё происходит наоборот. Углекислый газ - это вовсе не бесполезный побочный продукт обмена, а крайне важное соединение, которое намеренно образуется организмом. Оказывается, именно углекислый газ является регулятором просвета крупных кровеносных сосудов, называемых артериолами. Гипервентиляция приводит к ощутимому снижению уровня углекислого газа в крови и далее - к сужению артериол и резкому ослаблению кровотока. Снабжение мозга кровью ухудшается, и потому у штангистов в момент пикового усилия темнеет в глазах, и они нередко теряют сознание.

У силовиков существуют и другие причины для выполнения гипервентиляции. Обратимся к книге Б.И.Шейко "Пауэрлифтинг".

Цитата из книги "Пауэрлифтинг", Б.И.Шейко, Москва, 2005, с.58:

Готовясь к приседу, атлет <...> делает несколько быстрых вдохов-выдохов для того, чтобы приподнять грудную клетку, и финальный вдох примерно на три четверти максимального объёма лёгких.

В 60-х Воробьев защитил кандидатскую диссертацию на эту тему. Гипервентиляция с последующей задержкой дыхания при выполнении соревновательных упражнений тяжелоатлетами приводила к потере сознания последних прямо во время выполнения этих самых упражнений. Наверное, были жертвы =)
