Плавание-это на первый взгляд один из самых лёгких видов спорта, но нет. В плавание нужно правильно грести руками и ногами. Особенно сложно когда ты участвуешь в соревнованиях. Нужно не только правильно плыть, но и постараться всех опередить и занять первое место. Если не получится в первый или в любой другой раз , расстраивается нечего, в следующий раз обязательно получиться. Плавание- вид спорта или спортивная дисциплина, заключающаяся в преодолении вплавь за наименьшее время различных дистанций. При этом в подводном положении по действующим ныне правилам разрешается проплыть не более 15 м после старта или поворота (в плавании брассом подобное ограничение сформулировано по-другому);скоростные виды подводного плавания относятся не к плаванию, а к подводному виду.
Swimming.
Swimming is a seemingly one of the easiest sports, but no. In swimming you need to properly paddle hands and feet to help. It is especially difficult when you participate in competitions. Need not only the right to swim, but also to try to get ahead of everyone and take first place. If you fail the first or at any other time, there is nothing to get upset, the next time you need to turn out. Plavanie- sport or sports discipline, is to overcome the swim in the shortest time for different distances. While submerged under current rules now allowed to swim no more than 15 meters after the start or turn (in the breaststroke this restriction is formulated in a different way), high-speed types of diving are not to swim, and to an underwater view.
