Как сделать вывод о тренированности сердца?

Ответы

Автор ответа: petuhovoleg22

Сердце человека очень сильное и очень выносливое. Ибо оно постоянно перегоняет кровь через все тело, оно постоянно, без какого либо отдыха, сокращается и сокращается. Знаете, почему я назвал тему: тренировка сердца и развитие выносливости? Это специально, для некоторых деятелей, дескать, которых не интересует тренировка сердца, им бицуху подавай. Ох уже эти пляжники :). Однако друзья, вы очень сильно ошибаетесь, ибо: тренированное сердце повышает функциональность и выносливость организма в целом.
