The effect of the learning strategy for mastery on the competitive behavior and skill performance of the smash hit for junior badminton players

Abstract

The research aims to prepare a rehabilitation program for taekwondo and kickboxing players suffering from a simple anterior cruciate ligament tear and to determine its effect on some motor functions and the efficiency of the knee joint. The research community included (15) individuals with a simple anterior cruciate ligament tear who were officially registered at physical therapy centers in Babil Governorate. The research sample consisted of (12) male individuals aged 18-25, selected randomly from the research community after reviewing the medical record of each by a specialist doctor to confirm the type of injury, which is represented by a simple anterior cruciate ligament tear. The research sample was limited to those who had not undergone previous rehabilitation programs for their injury while continuing medication treatment, which was uniform for all individuals in both groups. Homogeneity and equivalence of the sample were extracted to ensure the players started from the same starting line. Subsequently, the specific variables of the research were identified, which are the motor functions of the knee, including (deep squats, step-ups, forward lunges, active leg raises in a straight position, trunk stability, quadrilateral rotational stability, shoulder movement) and the efficiency of the knee joint.

The pre-tests were conducted on 10/10/2024, and the post-tests on 10/12/2024. The rehabilitation program consisted of 24 rehabilitation units over 8 weeks, with 3 units per week and a duration of each unit ranging from 20 to 80 minutes. Finally, to extract the results, appropriate statistical methods were used for the current research. The researcher concluded that the rehabilitation program, combined with some assistive devices and radiofrequency and vibration waves, had a positive effect on motor functions and knee joint efficiency, thus treating the minor tear of the anterior cruciate ligament. As for the control group, there was a slight improvement in motor function and joint efficiency.
