The study aims to know the effect of a proposed preventive training
program using weight training and plyometric exercises on the symptoms and pain of the dominant shoulder associated with the performance and internal and external rotation of the shoulder joint and the muscular strength of the muscles working on this joint for handball players from (17:20) years during the training and competitive season, and the approach was used. Experimental groups using two groups, one experimental and the other controlling, on a sample consisting
of (16) players from the Edfu Sports Federation’s handball club from (17:20) years. They were randomly divided into two groups. An experimental group used the proposed preventive training program, and a control group did not use the program.

One of the most important results of the research was the effectiveness of the preventive program in both (reducing symptoms and pain of the dominant shoulder associated with performance, The efficiency of the range of motion of the dominant shoulder joint, in the development of the muscular strength of the muscles working on the dominant shoulder joint and in the improvement of the results of physical tests that measure the extent. Muscle) for handball players during the training and
competitive season, where the results of the statistical treatments indicated the differences between the pre and post measurements of the experimental group in favor of the post measurement, and the differences between the post measurements of the experimental and control groups in favor of the experimental group. Handball over (17) years to reduce the symptoms and pain of the dominant shoulder joint associated with performance, and to use the OSTRC program to prevent shoulder injuries as part of the warm-up and before players perform any throws with the ball three times a week during the competition period.
