 It also conducted a review of hydrodynamic principles that lead to a better lift and float, recalling the importance they have in the hydrodynamic laws of physics, will need to be completed stating that presents learning and perfecting different styles swimming.

  It is therefore justified stresses that affect thermoregulation of the water to a much greater extent than air, providing a thermal conductivity approximately 30 times greater. He exerts on the body, many influences and determines a specific effort. Horizontal body position body requires more energy expenditure but provides muscle relaxation and relieves backbone of much of the weight. Water pressure intensifies respiratory muscles and that water does not offer a solid support, the activity of the motor becomes dynamic. It's good to know that swimming is a sport that can prevent heart disease and lung.

 This paper addresses all categories of readers who want to initiate, deepen or enhance any of the four options correct swimming technique sport.
