The problems of students’ physical training individualization

Purpose: to determine characteristics of correlation of girl students’ and school girls’ subjective and physiological parameters of reaction to physical load. Material: in the research sportswomen of two age groups participated: adult qualified girl students-basketball players (n=40, age 20-22years) and junior basketball players (n=35, age12-13years). Registration of heart beats rate was fulfilled with «Polar RS300X». Simultaneously, we registered subjective feeling of loaf value (heaviness) by Borg’s method. Results: it was found that in conditions of natural training and competition functioning, with equal heart beats rate values school girls feel tension of fulfilled work subjectively easier. It can be explained by higher maximal values of school girls’ heat beats rate, comparing with girls students. Equal values of heart beats rate reflect different changes in girl students’ and school girls’ organisms. That is why they can not serve reliably informative indicator of load. Conclusions: we determined characteristics of perceived tension under load of game character. It can be connected with emotional tension, which is characteristic for basketball.

The study aimed to determine the suitability of testing the saliva of kickboxing athletes to show changes in biochemical parameters in dynamic of training. 8 elite male athletes (mean age 17.29± 0.31 years, body mass 66.82± 3.46kg, with 5.62±0.96 years of training experience) participated in the study. Indicators of lipid peroxidation and glycolysis (the concentration of lactic acid and pyruvic acid) were defined before and after a training session. Significant increases in indicators of lipid peroxidation activity indicators and the concentration of lactic acid (4-fold) were observed; analysis of correlation matrices confirms the absence of expressed changes. At the same time, significant decreases in catalase (10-fold from 3.69μkat/L to 0.39μkat/L) and pyruvic acid (from 3.92μl/l to 0.55μl/l) were observed. Our results confirm the value of using saliva to determine training load in an individual. Moreover, the study provided information on the importance of indexes reflecting a correlation of various biochemical indicators to estimate the sufficiency of training loads. The ease of sampling and informational content of saliva are reasons to use such tests in monitoring athletes’ functional state to prevent fatigue.

PROGNOSTICATION OF SUCCESSFULNESS IN ARM-WRESTLING ON THE BASE OF MORPHOLOGICAL FUNCTIONAL INDICATORS’ ANALYSIS

Purpose: determination of objective and subjective characteristics of students’ with different properties of nervous system fear of heights. Material: In the research 10 students of 18-19 years old age, who did not practice sports, participated. The students fulfilled one exercises: passing suspended ferriage in hiking. This exercise gives subjective perception of height and creates artificial conditions for appearing of fear. He exercise was fulfilled under all required safety measures and supervised by experienced instructor. Cluster and discriminant analysis were used. Results: we have shown that is possible to divide people into groups by indicators of functional changes in extreme situation in combination with indicators of psycho-physiological potentials and properties of nervous system. We have found that the most significant indicators for distribution of students into groups by individual typological properties are speed and accuracy of passing of psycho-physiological tests with different modes of signals’ supply as well as functional changes before exercise of extreme character. Conclusions: It was determined that students with strong type of nervous system had confidently less heart beats rate before fulfillment of extreme exercise than the students with weak type of nervous system. Subjective feeling of fear before fulfillment of extreme exercise was also confidently less in representatives of strong type of nervous system.
