 * __What does science have to do with swimming?__ **

· The science of swimming is mostly related with the motion of your arms and legs. The better teqnique you have and the faster you move your arms you go faster. This has been scientifically proven by scientist. H20 is made of:
 *  1.  **HYDROGYN
 *  2.  **OXYGEN

· Humans swim at 5 mph compared to a sailfish which swims at 65 mph that isn’t that fast
 * __Facts:__**

· Swimmers wear body suits because it has been scientifically proven that it makes you go faster because nothing is dragging you back. Swimmers also use swimming caps so their hair isn’t dragging them back.

__BIOMECHANICS AND PHYSICS__ Sports Biomechanics is the application of physics and mechanics to the human body during sport. In such a technical sport such as swimming, it plays a very important part. Humans aren't the best swimmers; we can swim at 5 mph compared to a sailfish which can move through the water at 65 mph. Water is 773 times as dense as air and 55 times as viscous. From the start, the body position on the block must be maximized to achieve the most efficient push off and get the body in position to enter the water, to make the 'hole ' to follow in through. Biomechanics also helps to understand the best body position to reduce drag following the dive, to maximize the speed that is achieved off the blocks. After the push off the wall, body position is also important to have a streamlined glide away from the wall and reduce drag. For each stroke, the technique has developed over the years due to close examination and research by sports biomechanics staff.

__DIET__ Swimmers eat a lot to get out the energy so they can swim faster and win the racesmedia type="custom" key="4960515".

__EXERCISE__ The swimmers do about 6 hours of trianing a day to keep up their fitness and get their heart rate up and going for a number of minutes. Swimmers have to excersize daily so they can be fit and ready for the races. The science in excersize is all the body flewards we burn.

__GRAVTIY__ The gravity of the persons body makes them float to the top of the water and makes them lighter so they can go faster to reach the end first and win the race and get a metal for their country.

__DRAG__ When swimming through the water, the body will undergo a force due to resistance, or drag. This force is, given the magnitude of the competitive swimming speeds, predominantly due to turbulence behind the swimmer. Furthermore, when movement occurs at the water surface, additional resistance will arise due to wave formation by the swimmer. This total drag force is depending on swimming velocity to the power of (at least) two. Drag is therefore one of the factors that may limit swimming performance. = =
