Abstract EN

This study is one of the modern scientific attempts that deals with the study of the strength characterized by speed and its relationship to the strength and accuracy of shooting performance during different levels of the intensity of physical effort of the Yemeni youth team players, and the possibility of benefiting from it by those interested and specialists in the field of handball training, which contributes in directing the attention of researchers to address similar problems in other sports.

Through the researcher's belief in the need to pay attention to special muscle strength exercises and to use appropriate training methods for them, strength-with speed training is one of the modern training methods to improve the strength and accuracy of shooting performance of handball players.

The problem lies in the inability of the Yemeni youth handball team players to score the largest number of goals while participating in external competitions in the International Challenge Cup.

The research aims to identify the relationship of the distinctive strength characterized by speed with the strength and accuracy of shooting during (low - medium - high) physical effort among the Yemeni youth team handball players.

In his study, the researcher used the descriptive approach with its steps and procedures because of its relevance to the nature of the study and the achievement of its objectives.

The sample of the research is represented by the 25 players of the youth handball team in the Republic of Yemen, who were chosen in a deliberate way.

Hypotheses: 1-There is a statistically insignificant relationship between the strength characterized by speed and the strength and accuracy of shooting during low effort for the study sample.

2-There is a statistically insignificant relationship between the strength characterized by speed and the strength and accuracy of shooting during medium effort for the study sample.

3-There is a statistically significant relationship between the strength characterized by speed and the strength and accuracy of shooting during high effort for the study sample Conclusions: 1-There is no correlation coefficient between the strength characterized by speed and the strength and accuracy of shooting during low effort.

2-There is a significant correlation between the strength characterized by speed (the explosive strength of the legs - the strength characterized by speed of the right leg) and the strength and accuracy of shooting during high effort.

3-The test of the strength and accuracy of shooting during high effort is the most realistic and closest to the conditions of the match than the rest of the levels of effort for the strength and accuracy of shooting in handball.

Recommendations: -1Emphasis on the use of tests that are close to the conditions of play and competition when measuring physical and skill qualities of handball players.

-2Conducting more studies similar to the nature of the current research and recognizing the effect of a proposed training program to improve the level of the relationship between strength and shooting accuracy during the levels of physical effort, provided that the research methodology is experimental.

3-The use of strength characterized by speed exercises in training programs helps to develop the muscles working in high jump, which leads to the development of the efficiency of these muscles and improves the level of achievement of the research sample in the tests and in developing the vertical mechanical ability of the sample members in a way that serves the technical performance
