Abstract: Preventive exercises are one of the methods used to avoid injuries or weakness in the muscles by protecting the joints, tendons, ligaments and muscles working on them, as some weightlifting players for people with motor disabilities are exposed to injuries to the deltoid muscle of the shoulder joint, and the reason for these injuries is the nature of the effectiveness that depends in a way Head on the muscles of the shoulder joint, around which the quality of performance revolves, so Preventive exercises play a positive role by restoring the level of those muscle groups to their normal state of strength and muscular balance among the muscle groups. If the researchers Preparing exercises to protect the deltoid muscle (front and back) of the shoulder joint and assessing those using EMG technique for female weightlifting players with motor disabilities. And knowing the percentage of muscle strength that it has after the preventive curriculum, where the number of the sample was (6) national team players, and they were chosen in a deliberate way by diagnosing weaknesses by a physiotherapist, as the researchers developed a set of preventive exercises in the manner of performing the installation method, then Relaxation with contraction of the moving muscles (central and eccentric) by static and mobile stretching, weight training and resistance exercises, the duration of the preventive units lasted (8) weeks By (3) units per week, the time of the preventive unit (25-30) minutes, the weekly training days (Saturday, Monday, Wednesday), as the researchers concluded that the application of the preventive exercises used has a positive effect in increasing strength and muscular balance between the deltoid muscle fibers (front). And the background) of the shoulder joint among the players of the research sample, and this was evident through its evaluation with EMG technology for the pre and posttests, the results of which showed that there was a development in the muscular balance between the fibers (front and back) of the deltoid muscle, and in good proportions, which indicates the presence of muscular balance Between them after the end of the period of preventive exercises, the researchers recommend to use preventive exercises to strengthen the muscles working on the shoulder joint, Using rubber bands that perform in a central and eccentric manner.
