Objective: Aim: To determine the level structure of the graph model of the system of clinical and instrumental indicators of athletes with herniated intervertebral discs complicated by spinal stenosis, and to determine the regression model for these indicators.
Patients And Methods: Materials and Methods: This observational study involved 64 athletes (14 - rugby players, 16 - handball players, 15 - basketball players, 19 - football players) with intervertebral disc herniation, complicated by stenosis of spinal canal. Research methods: visual method to evaluate the likelihood of a data set's normal distribution; correlation and regression analysis; method for determining the ordinal function of a graph through the application of an adjacency matrix, specif i cally utilizing Demucron's algorithm.
Objective: Aim: To concern the scientific substantiation of a complex ergometer tests of aerobic and anaerobic character and quantitative criteria for assessing the condition of female handball players` respiratory and power supply systems in the maximum.
Patients And Methods: Materials and Methods: Descriptive analysis, correlation analysis, factor analysis. In order to solve those tasks within the framework there were measured the indicators of two hundred young female handball players at the pre-basic training stage.
Objective: The aim: To analyze the features of changes in the functional state of the vascular endothelium of handball players in the dynamics of the training process, at different levels of the body's hypoxic state.
Patients And Methods: Materials and methods: Theoretical methods, the method of Corretti et al. with the use of high-resolution ultrasound, Fisher test with the calculation of the Fisher criterion and the Bland-Altman method.
