An analytical study of the absolute angles of the body parts at the moment of launch and the percentage of their contribution to the completion of the weight push for young people

Abstract

The study aimed to analyze the absolute angles of the body parts at the moment of departure and to determine the percentage of their contribution to the completion of the weight throw for young people. The researchers used the experimental method to suit the nature of the problem by designing one experimental group. The research population was determined from weight throwing players for youth under the age of (20 years) and their number was (3 players). Field research procedures included conducting video photography and motion analysis to extract the absolute angles of the body parts (the angle of the leg, thigh, torso, upper arm, forearm, in addition to the starting angle). The researchers concluded, through analyzing and discussing the results of the research, that there is an inverse correlation between the absolute angles of the body parts with the line. Horizontal and achievement. It was also shown that the best contribution percentage was achieved by the absolute torso angle and the launch angle. The researchers recommend emphasizing the conduct of motor analysis to identify areas of defect and weakness in motor performance, and conducting periodic tests and motor analysis to monitor the level of development in the mechanical and technical aspects.
