Biomechanical profile of wrestling holds based on fuzzy logic algorithm of elite freestyle wrestlers of the city of Joybar in six weight classes

The purpose of this study was to determine biomechanical profile of wrestling holds based on fuzzy logic algorithm of 57 elite freestyle wrestlers in the city of Joybar . Dynamic posture stability index, time to stability, linear momentum, upper limbs mechanical power were determined as biomechanical variables for the analysis of wrestling holds. Findings were: (1) By designing new tests for analysis of holds such as rear throw, crotch lift, bridge, double leg pickup, flying mare, over under, and three types of stances was prepared the skill fitness profile of elite wrestlers into six weight classes; (2) fuzzy logic algorithm and principal component analysis could be used to score to the skill fitness of each wrestler . Generally, the results emphasize the necessity for the analysis of wrestling holds using the standard tests and design of scoring algorithm to compare the skill fitness of wrestlers in each weight class.
