The problem with the research is that coaches focus only on training programs and physical and skill preparation, and do not focus on the important aspect of preserving the player’s physical and physiological safety. Therapeutic and rehabilitative methods such as thermal wax and ultrasound frequencies were not used. Therefore, the researchers worked to introduce a rehabilitation program that includes treatment by wax. In addition, ultrasound frequencies to improve the physical and functional condition of handball players. The researchers will use the experimental method with one experimental group due to its suitability to the nature and method of the research. The research community also included (25) handball players applying to Al-Kout Sports Club, and (18) players were selected by simple lottery to be a sample for the research, and they are members of the experimental group. As part of the research procedures, the researchers prepared a program suitable for a research sample, and after obtaining the results of the data of a research sample used through the main experiment, the researchers processed it statistically using the spss program, and in light of the research results that the researchers reached, a set of results were concluded, the most important of which was proven The proposed rehabilitation program using ultrasound frequencies and thermal wax showed an improvement in the level of physical performance of handball players, as it showed improvement in all of (speed, agility, flexibility, and muscular strength). The proposed rehabilitation program using ultrasound frequencies and thermal wax did not show an improvement in Endurance level. The most important recommendations are the need to use the rehabilitation program before any training unit and regularly. Work to conduct similar studies, and this indicates the development of the science of training and rehabilitation and preventing injuries.
