The importance of the research lies in shedding light In preparing competitive exercises with a numerical deficiency to develop some physical abilities Distention To cover the Defensiveness For the player To address numerical shortages that occur during the match due to situations Stop For players who violate the rules of the game, this situation requires the players to increase the effort exerted to compensate for the deficiency occurring in the team and fill the gaps quickly, which requires the coach to think about raising the level of physical fitness of the players through training units. And procedure Special exercises for this case.

As for the research problem, it depends on the researcher’s experience that Being what trainer that Notice When a situation of numerical deficiency occurs in the team, it is affected Performance in defense He may make mistakes in different playing situations, which may cause him to lose the match, and through the attention of the researcher that with this game and his follow-up of many matches, he noticed a weakness in some physical abilities that caused him not to return to take the appropriate position in defense or commit legal violations that resulted in him leaving the field due to a suspension penalty. And it has use. The two researchers’ Experimental approach And it has It has been determined sample Find an illusion player In the specialized school Hand ball by ages (15-19) year In Al-Muthanna Governorate and Adult Their number (28) player After excluding the (3) goalkeepers And identifying (5) players as a reconnaissance sample And (10) players for each control and experimental group. It was concluded. The two researchers. The suitability of the training method (interval and repetitive) to the age and training stage of the research sample, which contributed to the development of the physical capabilities of defensive coverage. Also, the auxiliary tools used in training (weight belts, medicine balls, and markers) had a major role in developing the physical capabilities of defensive coverage players, and the gradual increase in the training load was important. Regulating the intensity between exercises and groups plays an important role in the appropriate functional adaptation for a state of development in physical abilities, and the similarity of exercises with real competition conditions contributes to increasing the players’ drive towards...Performance The development in physical abilities as a result of the use of competitive exercises led to raising the level of defensive coverage performance of the players.
