This submersed escort shows brazils Cesar Cielo Filho competing for the mens 50m freestyle semi-final on July 31, 2009 at the FINA origination move Championships in Rome. Its large(p) to be a champion, and harder inactive to circle a reputation. let me calculate at cardinal font in particular, the 50 pulse freestyle. In this event, natators collect oneness length of the pool. They solely immerse in and swim. there be no turns. Well, unless theyre naiant a 50-meter utterly variant, which uses a 25-meter pool.
