BIOMECHANICAL STATUS AND DEVELOPMENT LEVEL OF FUNDAMENTAL MOTOR SKILLS OF CHILDREN FROM 7 TO 10 YEARS

Abstract

The research covered a group of fundamental motor skills by defining their biomechanical status and development levels. We analyzed 12 basic motor skills, 6 of which are locomotor and 6 of manipulative type. Skills were analyzed with qualitative biomechanical analysis and then wеre applied appropriate algorithms and mathematical statistical programs for data processing in order to determine their biomechanical status. The research results show that the basic motor skills seen as a whole have expressed heterogeneous biomechanical characteristics. After applying the method of principal components to the results of the qualitative biomechanical analysis, 3 principal components were obtained, while applying the same method to the results of the development level assessment, 4 principal components were obtained. The development level assessment was carried out on 137 male subjects aged 7 to 10 years. Each performance of the subjects was recorded with a video camera and then the presence of performance criteria were registered through predefined qualitative -biomechanical patterns for performance in movement. The data shows that although there was a monotonous increasing trend in the average score in each skill, statistically significant difference was determined in 8 motor skills. Statistically significant difference was determined in the average total score of achievements in locomotor and manipulative skills. In each of the skills the most difficult and the easiest performance criteria were determined. The data indicates a low level of development of the fundamental motor skills that could be attributed to the interaction between the factors individual-environmenttask, especially emphasizing the influence of the environmental factor.
