In backstroke, you cannot flip onto your stomach. In butterfly, your feet cannot separate. In breaststroke, you may not flutter kick. 
In competitive swimming, there are some words that may confuse non-swimmers like flip-turn, DQ and what 200, 400, 1600, etc mean.
A flip-turn is the turn a swimmer does when they touch the wall and turn their body (and flip it) to continue onto their next lap. The faster you can do this, the faster your race will be.
A DQ or (disqualification) is when you do something against the rules in the middle of your race, so judges can "DQ" you. This means that your time will not change no matter if you broke a world record or if you won the race, they cannot count your time or position in the race.
The numbers in the title of a race are the distances the swimmers are going. The higher the number, the longer the distance the swimmer is swimming. It can be measured in yards or meters. 
A cliche that my coaches always told me about was "swim like a shark is chasing you"
which literally means, swim like a shark is chasing you. Swim as fast as you can.
Michael Phelps was born on June 30, 1985 and attended University of Michigan. He swims for the Olympic team.
