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 3.69 μkat/L to 0.39 μkat/L) and pyruvic acid (from 3.92 μl/l to 0.55 μl/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.

Abstract. Purpose: to study interconnections of students' morphological functional indicators and their influence on level of sportsmanship. Material: in the research 17 students, practicing martial arts, participated. 62 indicators were determined: anthropometrical, goniometrical criteria of arms joints' status; tapping test and maximal frequency of grabs in impulse mode. Results: we found that maximal contribution in system is made by hand dynamometry of right and left hands, body length and mass, chest circumference, width of shoulders; maximal frequency of grabs by right and left hands. It was confirmed that there are correlations between students' morphological functional indicators. The highest contribution to formation of functional system is characteristic for anthropometric indicators. Results of maximal grabs in impulse mode made rather sufficient contribution in system's formation that is confirmed by great quantity of correlations. Analysis of character, strength and orientation of correlations witnesses about informative potential of this test and permits to recommend it as screening for control of sportsmen's state. Conclusions: we determined that indicators of hand dynamometry system formation illustrate that for martial arts wrestlers strong grab was very important. It is ensured by strength of hand muscles.

Purpose:to work out methodic of arm wrestling successfulness prognostication by morphological functional indicators and substantiate it. Material:189 sportsmen (of age 21.62 ± 0.85 years) were tested. We fulfilled goniometric testing of arms' joints (n=27) and hand dynamometry (n=50). Characteristics of physiological tremor were studied (n=29). Strength of forearm's muscles was determined (n=33) as well as the strength of hand fingers' extensors separately (n=50 Besides, prognosis implies summing up of these coefficients for achievement of one of prognostic thresholds. The value of these thresholds was determined at level of ± 13, that corresponds to 95% (p<0.05) probability. Achievement of threshold + 13 and more means sportsman's successfulness higher level. In case of lower threshold achievement successfulness probability is low. Conclusions:the conducted researches permitted to work out methodic of arm wrestling successfulness prognostication by morphological functional indicators and substantiate it. The offered methodic is based on sequential analysis by Wald and is a simple, informative and objective tool of arm-wrestlers' condition control.
