A COMPARATIVE ANALYTICAL STUDY OF THE ANTERIOR MUSCLES OF TWO LEGS AFTER ONE OF THEM SUFFERED A TEAR IN THE TWIN MUSCLE OF FOOTBALL PLAYERS EXPERIMENTAL RESEARCH ON A SAMPLE OF SPORTS INJURIES FOR THE APPLICANT CATEGORY

Abstract

The aim of the study was to identify the strength of electrical activity of the muscles of the front legs when suffering from a twin muscle tear in advanced soccer players, and to determine the differences in comparing the injured leg with a healthy one. The researchers adopted the experimental method with a one-group comparative method. The sample was deliberately selected from the players of Basra Governorate Football Clubs, and consisted of (8) injured players who were homogeneous in physical and training measurements, after excluding (6) players for medical reasons and participating in the reconnaissance experiment. The research was conducted in the Physiotherapy Laboratory at the Faculty of Physical Education - University of Basra, for the period from February 26, 2023 to April 15, 2023. Research tools: French Electrical Muscle Activity Measurement (EMG), Gel Testing Humidifier, Height Measurement Restameter, and Medical Scale. Statistical methods: Data were processed by statistical package (SPSS) using arithmetic media, standard deviations, coefficient of difference, and T-test for independent samples. The most important conclusions are that there are significant differences in the strength of electrical activity of the muscles of the front legs between the injured and healthy legs and in favor of the healthy leg. The rupture of the twin muscle leads to a sharp decline and a significant loss of the efficiency of the muscular electrical activity of the affected leg compared to the healthy one as a result of muscle destruction and impaired neuromotor function. The EMG device has proven high accuracy and outstanding laboratory diagnostic capability in determining the level of injury severity and accurately comparing changes. The most important recommendations: the need to rely on accurate laboratory tests such as an EMG device to determine the extent of the muscle damage, and not to allow players to return to the stadiums without integrated rehabilitation based on scientific foundations to avoid the tear turning into a chronic injury.
