Abstract
The training process as well as the adaptation of the body is a multifactorial process. This means that the factors can vary from the morpho-functional and genetic characteristics of the subjects to the patterns of a selected training program, dosed and loaded by the person who leads the instructive-educational process. The body’s adaptation to these factors is directly related to the methods and means used. During the training process it is necessary to follow a series of principles and rules, which help and ensure the proper conduct of the training system for athletes.
