The hydrodynamics of swimming is based on principles similar to the aerodynamics of flight, an object that is flatter and more streamlined through the water or air with greater speed than an object with angles that offers greater resistance.
swimming posture causes little flat aerodynamic turbulence. This means that the swimmer will be with little resistance to stop it, and require less energy to propel themselves forward.
probably correct body alignment, as illustrated in these two pages, is the most essential element of a good style swimming, since the effective stroke, the style of the kick and breathing techniques are dependent on it .
As better hydrodynamics of swimming in
The body must occupy a position lateral and horizontal aerodynamic. Aerodynamics horizontal plane and keep the body in shallow water, so that the strength of forward momentum will be minimal.
By aligning the body laterally keep it straight, without stirring from one side to another, increasing the resistance to have a higher body surface.
