Training is a long-term systematic effects on the body in order to create increased physical or mental performance, as well as increase the body's resistance to various external influences. Training refers to any activity, but is of particular importance for the sport. Sports training is the systematic and systematic use of physical exercises to improve motor skills, strength, agility, speed. Medical control (see) for sports training is required. Medical workers regularly examine the state of the cardiovascular system of athletes, monitor body weight, general condition, etc., to prevent the occurrence of overtraining. This condition appears in case of excessive sports loads in the form of a feeling of fatigue, a drop in athletic performance in training and competition, in refusal from training and even from playing sports in general. To remove overtraining, it is necessary to cancel training for a more or less long period.
Successful training is provided by year-round and its continuity over a number of years, a gradual increase in workload, proper alternation of work and rest, nutrition, medical supervision.
Medical workers judge the quality of training on objective (improving the performance of the cardiovascular system, increasing the vital capacity of the lungs, increasing muscle strength) and subjective indicators (the presence or absence of fatigue , the speed of onset of fatigue, the speed of recovery of the former state). Training leads to specific changes in various peripheral organs, which is also an objective indicator of its quality. An example of such changes may serve as morphological changes in the locomotor apparatus arising from constant and prolonged sports training: muscle hypertrophy, increase in the size of individual muscle fibers, thickening of the cortical bone layer, and the like.
