Abstract
Appropriate technical performance is directly linked to the goal of this motor performance, and achieving the goal depends on a number of requirements, including the application of the laws and conditions that are subject to the possibility of achieving performance for precise parts of the movement. The researchers wanted to study one of the most important stages of the effectiveness of discus throwing, as the rotation stage is considered the key to performance. The correct way to reach the throwing position in the best way, hence the importance of research into manufacturing a laser device that is attached to the foot of the discus thrower from below, where a sound appears when the man’s heel touches the ground during the rotation phase, which in turn increases the speed of rotation within the throwing circle, which is reflected to effectively increase discus throwing performance. Therefore, the research problem was set to solve one of the issues that learners and instructors suffer from in discus throwing, which is the slow speed of rotation within the throwing circle. This small device works to teach the player the motor performance of raising the foot of the spinning leg and relying on the rotation on the comb. In this research, the researchers seek to answer the questions: Does the manufactured laser device help greatly in reducing the friction between the ground and the rotating foot in the discus throwing circle? The research aimed to prepare motor exercises using a proposed laser device attached to the heel of the foot that would help in learning motor performance and increasing rotation speed within the discus throwing circle. The researchers used the experimental approach with a one-group design with a pre- and post-test, and (5) students were selected from the trainees and practitioners of throwing events from among the students of the College of Physical Education and Sports Sciences in Al-Jadriya to represent the research sample in an intentional manner, and through the application of 8 educational units based on the use of the device manufactured in the department. The main part of the educational unit, and the results showed the effectiveness of the work of the laser device in developing the speed of rotation and in improving the motor performance of the rotation stage and the completion of the discus throw for young people, and this achieves one of the sustainable development goals of the United Nations in Iraq which is (Good Health). The researchers recommend using the laser device (L.F) attached to the bottom of the heel of the foot in learning and developing the motor performance of the rotation stage of the discus throw before teachers and trainers for this event.
