Опір води та його вплив на швидкість плавання

Abstract

The article considers hydrodynamic swimming, which is characterized by the interaction of the water medium with the body moving in it. The main condition of dynamic swimming is the reaction of water resistance, which occurs as a result of limb movements. Thus, water resistance is directly proportional to its density, the average cross-section of the swimmer and the square of the speed of its movement. The specified dependence of resistance on changes in swimming speed indicates that the technique of swimming movements and the method of training a swimmer should ensure that he swims each segment of the distance at the same speed and bring the swimmer closer to a uniform speed of advancement within each cycle of movements of all sports methods of swimming.
