Dynamics of age-dependent adaptive capacity estimated by method of L. A. Konevskikh in boys 8-12 years of age engaged in Greco-Roman wrestling sports

Aim. To estimate of adaptive potential in boys 8-12 years of age, engaged in Greco-Roman wrestling based on method by L. A. Konevskikh in different stages diurnal the light day during the week. Material and methods. Analysis of adaptive potential (AP) calculated based on method by L. A. Konevskikh et al. (Patent RU 2314019) was performed in 22 boys (8-12 years of age), who are regularly engaged in Greco-Roman wrestling. In boys who voluntarily agreed to participate resting heart rate was determined and the formula was used to estimate the level of AP. Measurements were taken at 8, 12, 16 and 20 hours in 7 consecutive days during the week. Results. Using the method of L. A. Konevskikh et al. the boys showed that none of them had a satisfactory level of adaptation. As age of boys increased, AP gradually decreased numerically and reached the values of the stress of adaptation mechanisms. Of note, in boys 10-12 years of age at 8 a. m. and in boys 11-12 years of age at 8 p...
