Changes in some anthropometric indicators in sportsman-athletes at the stages of long-term training

Abstract

Literature data previous own studies indicate changes in anthropometric parameters in athletes due to the intensity and duration of exercise. An assessment of changes in some anthropometric indicators in athletes at the stages of long-term training. The paper summarizes the results of a survey of 53 athletes (athletes) at the stages of long-term training. The study involved 3 groups of athletes: 1st group - (15 athletes) - athletes at the stage of specialized basic training. 2nd group (28 athletes) - athletes in preparation for higher sporting achievements. 3rd (10 athletes) - athletes at the stage of maximum realization of their individual capabilities. The age of the athletes is 18-20 years, the track and field experience is 5-10 years.
 The anthropometric study included: Quetelet's weight-height index, the relative amount of muscle tissue, the absolute amount of the bone component of the body. The indicators were determined according to generally accepted methods. The results of anthropometric survey are processed by variational-statistical methods. The study found that the competitive result of athletes depends significantly on physical development and data of athletes. Those athletes can be considered the most promising, who have high anthropometric performance. At the initial stage of selection more attention is paid to motor abilities, and during selection to sports improvement groups preference is also given to the functional capabilities of the athlete.
