The Effect of Using a Proposed Training Device on Special Strength and Discus Throw Performance for Para-athletes (Class 54).

Abstract

The Importance of the Study:

The significance of this study lies in highlighting the importance of the proposed training device, which aims to improve the movement trajectory of the discus during the throwing stance (power position) and release phase. Additionally, it seeks to enhance and develop the special strength of the muscles involved in these crucial phases, thereby aiding in skill-related strength development. This contributes to the overall improvement of discus throw technique and achieving outstanding performance for para-athletes in Class 54.

Study Objectives:

The study aimed to:

1. Design a proposed training device for discus throw para-athletes in Class 54.
2. Identify the impact of training using this device on developing special strength and performance in discus throw for Class 54 para-athletes.

Research Methodology:

The researchers employed the experimental approach with a one-group pretest-posttest design, as it was suitable for addressing the research problem. The sample was intentionally selected from the Diyala Sub-Committee of the Paralympic Committee for athletics, specifically discus throw para-athletes in Class 54. The total number of athletes was 8, but 2 were excluded for pilot study purposes, resulting in a final research sample of 6 athletes, representing 80% of the original population.

Research Procedures:

• Design and fabrication of the proposed training device.
• Pilot studies and pretest and posttest assessments of maximum strength, explosive strength, and strength distinguished by speed.
• Implementation of an 8-week training program, consisting of 3 training sessions per week, totaling 24 training sessions during the experiment.
• Each training session lasted 90 minutes, with 35-40 minutes dedicated to exercises using the proposed device during the main section of the session.

Key Findings:

The study concluded that:

1. Training with the proposed device led to significant improvements in special strength (maximum strength, explosive strength, and speed-strength) among the participants.
2. The training program enhanced arm and trunk strength, which contributed to improved discus throw performance.

Recommendations:

The researchers recommend emphasizing the use of the manufactured training device as an auxiliary tool for developing special strength in discus throwers, particularly para-athletes in Class 56.
