IanThorpe, one of the best swimmer of the time and one can not forget MichelFeleps the best ever swimmer also. How do they become world’s best swimmer? No doubt!!They did it with their best of hardwork, dedication, and strong will power. Butalong with all these factors they also used science, yes science of swimming.
Swimming is one of the games which uses most the energy and all the muscles ofthe body also worked in this process. So it becomes very important to storeenough energy and to make muscles strong to get the success. Science is givingmajor ideas for swimming in all the aspects whether it is weight, cloths, hairstyle, muscles, techniques to move etc. swimming is all about to flow withoutany resistance. Basically resistance is the hindrance for any object and if youminimize the resistance, speed or any action becomes very fast. Swimming is moving your bodythrough water that’s either in a swimming pool or in the ocean or somewhere inbetween. If you’re swimming completely under the surface (for example, scubadiving), you’re moving through relatively still water; between air and water, with your legs, arms,head, and body moving from one element to the other and back again, speeding upor slowing down as they cross the border.Before wecan understand the science of swimming, it helps to remember that air is a gasand is very different from water a liquid.
The biggest difference is that wateris much more dense and heavy in other words,thicker..Thedifference between air and water makes a huge difference to how we can move onair and land. When you walk on land, the main thing your body has to do is workagainst gravity like lifting your legs, swinging your arms, and keeping youfrom toppling over through constant adjustments of your balance and a littlebit of friction where your shoes meet the ground. If you move more fastair resistance becomes a more important force than gravity; unless you’rewalking into a really strong wind, you barely notice the air while you’rewalking. When you’re in the water, gravity is much less important becauseyour buoyancy (tendency to float) largely cancels it out. Themain force you have to think about as a swimmer is drag—water resistance.
Newton’slaws of SwimmingThe first law outlines the concept of inertia.It says that all the objects in this world resist the change in their positionuntil or unless an external force is applied. More mass, more inertia whileless mass less inertia. The second and third laws are of more interest. Thesecond law explains the connection between force and acceleration:if you push or pull something, it starts moving or goes faster. The bigger theforce you apply, the more acceleration you get; the longer you apply the force,the bigger the change in momentum you can achieve. Where swimming is considered, the third law ismost important.
According to this law that when you apply a force to an objectand it applies an equal force to you—in the oppositedirection.This law is often called action and reaction and it’s theeasiest way to understand for a scientific non-swimmer to think importance ofthe water. You might know that if you kick backward againstthe wall of a swimming pool, you shoot forward through thewater. The same applies to actual swimming strokes. If you want to swim forward throughwater, you have to pull water backward with your hands. If youwant your body to stay up, floating on the surface, you need tokick down with your legs.
If you’re swimming along and youwant to stop suddenly and stand up, you can pull your hands down in front ofyou and your legs will swing down behind you, so you land in an uprightposition on your feet. How to minimize drag in swimming –
