Levels of muscle regulation of dynamic balance in vertical posture among the athletes
The article analyzes the results of stabilometric examination of 555 athletes-students aged 19-23 years from the faculty of physical culture and sports, received during the dynamic balance evaluation in the Romberg test with closed eyes in European stance swaying back and forth without separation from the support. From the total number of the surveyed students there was randomly selected the sample of 201 people, the results of which were subjected to statistical analysis to determine the numerical values of the levels of muscle regulation of the vertical posture among the athletes in the program STADIA for Windows. The author built the exponential regression model based on threshold kinesthetic sensitivity at athletes from the level of agreed muscle strains (P=5.92E-21). The cluster analysis identified 5 classes that have been tested with the discriminant analysis (P=0.04709). The research results allowed classifying 5 levels of muscular dynamic regulation of balance in vertical posture among the athletes, which are based on the values of kinesthetic sensitivity threshold and coordinated muscle strains.
