Monitoring the rates of young swimmers’ physical development on the basis of determining the hormonal status of the body

The methodology for monitoring the dynamics of physical development based on the systematic determination of changes in the hormonal status of young swimmers’ bodies of both sexes in the age range from 11 to 17 years is substantiated. It is shown that the dynamics of the concentration in of testosterone the bodies of male swimmers and growth hormone of female swimmers reflects the dynamics of puberty and allows you to diagnose delay, advancing and “jumps” in puberty. It is proposed to continuously monitor testosterone in male swimmers for boys and young men and somatotropic hormone in female swimmers for girls and young women aged 11-17 to monitor the dynamics of physical development and puberty within the framework of the developed five-stage technique. It is noted that the developed methodology complements the widely used methodology for determining puberty, based on the differentiation of secondary sexual characteristics, which significantly increases the accuracy of diagnosis and the timeliness of the manifestation of «jumps» in physical development.
