Information Analyses without Cognition Through Visual Observation to Develop Some Indicators of Biomechanical of Hammer throw for Advancing Throwers

Abstract

ABSTRACT

The hammer throw is one of the most difficult events of track and field. Studies still have hand in improving out about throwers performance by information analysis methods for biomechanical deep insight. A lot of studies which discover the difference of the proficiency are reported for the feedback of dynamic scene of sports. In this paper, it aimed to know effect of information analyses without cognition through visual observation to develop some indicators of biomechanical of hammer throw for advancing throwers. An experimental intervention was used in present study, 6 players of hammer throw aged (23.65, ±1.7) and with training age (8.81, ±2.5), and their achievements in hammer throw (46.70, ±5.65) were participated in current study. Teaching approach was conducted for a period of 6 weeks, 3 times a week by depending on a strategy of the player control which based on filming his skill performance and then shows every endeavor immediately after completion of performance. Data was analyzed using Unpaired T Test. It was observed an improvement in the instantaneous momentum of the moment of throwing, development of outcome accelerating (vertical and tangential) during hammer throw, and declining the amount of kinetic differences between the status of throwing and final throwing and development of final achievement. So it was concluded that the constant surveillance to collect information about the performance contributed effectively to the development of instantaneous momentum and final accelerating. Moreover, the continuous monitoring and analysis of information without cognition about performance movements, helped to move sensory information and respond to give a sign about what is required of kinetic cells performance which are responsible of performance.
