Abstract

Objectives: The study of effect of sports loads on adaptive and regulatory capabilities of female students’ bodies with various motion states is of interest from the perspective of discovery of mechanisms of long-term and individual adaptation to physical effects. Method: Female students, which are the members of volleyball and basketball group (53 persons) aged 18-21, served as test subjects. Female students not engaged in sports activities (save for 2 hours of physical education per week) have been examined as a control group. Electrocardiogram (ECG) recording and calculation of heart rate variability (HRV) were carried out by means of Poly-Spectrum-8/EX hardware and software complex in prone position for 5 minutes. Findings: Two regulation groups have been identified in each sport: with the predominance of central and autonomous type of regulation. The first group with the predominance of central type of regulation is characterized with lower values of time analysis – SDNN, RMSSD, pNN50%, CV% – and high SI. The predominance of slow waves of the first order (LF) and the second order (VLF) has been registered in the rate spectrum. Sports physical loads result in growth of general power of regulatory impact, which increases adaptive capabilities of female athletes’ bodies. Sports activity in the course of volleyball and basketball training sharpen tension of adaptive mechanisms and significantly increase “adaptation price” for representatives of the first group; especially high tension of adaptive mechanisms was found in the first group of female basketball players. The most favorable adaptive status was shown by female athletes of group 2, which makes it possible to conclude that sports physical loads favorably affect female athletes of this group, since they had significantly higher adaptive potential as compared to the test subjects. Application: In general, sports activities promote normalization of regulatory mechanisms status and reduction of quantity of members of the first adaptation group (with predominance of central regulation type). Such regulation type is characteristic of the absolute minority of female athletes, while a half of the test subjects, who are not female athletes, demonstrate such regulation type.

Abstract

Objectives: The article is aimed at research of somatotropic function of boys’ pituitary gland and adrenal cortex in a state of relative rest and under physical load for adequate and complete assessment of their functional capabilities. Methods: Functional capabilities of somatotropic pituitary gland function were examined using PWC170 test. The level of activity of pituitary gland and adrenal cortex was examined by radioimmunoassay technique before the load and in 15 and 45 minutes after the load. The results were statistically processed according to the Student-Fisher variation, statistic technique and rank correlation method, the variability of parameters was assessed by means of the variability coefficient. Findings: To determine the functional reserve of pituitary gland and growth capabilities of the body, a comparative assessment of somatotropin dynamics was made in the state of relative rest and under various loads. The following results have been achieved: comparative assessment of pituitary gland response under different kinds of physical load, identification of its peculiarities, characteristics of general rules of pituitary gland response to the examined loads on boys in the course of somatic growth, simultaneous examination of the response of pituitary gland (with respect to somatotropin) and adrenal cortex (with respect to cortisol) under various loads. This paper shows that pituitary gland activity increases under physical load with PWC170 power. Pituitary gland response in the 45th minute is more significant than response in the 15th minute after the load. In each specific case, the trend of response (increase or decrease), incremental value of somatotropin and the rate of response were subject to the value of the initial level of pituitary gland activity. Application: This article is of practical value for hormonal therapy.
