تأثير تطوير تحمل القدرة العضلية على الكفاءة الوظيفية للرئتين و مستوى الأداء المهاري الهجومي لناشئي كرة اليد

Abstract EN

The research aimed to develop a proposed training program to develop muscular endurance and know its effect on the functional efficiency of the lungs (the vital capacity of the lungs- the volume of exhaled air at one time- the volume of inhaled air at one time- the number of breaths - the maximum oxygen consumption- the respiratory fitness coefficient) and the level of performance Offensive skills (dribbling ball speed - passing speed and accuracy- shooting strength and accuracy) for handball juniors under 16 years old, and the researcher used the experimental method on a sample of (14) handball juniors under 16 years old.

Among the data collection tools are: muscular endurance tests - functional measurements of the lungs - skill tests - the proposed training program for developing muscular endurance.

Among the most important results: The proposed training program has a positive and statistically significant effect at the level (0.05) on the endurance of the muscular ability of the arms and legs of handball juniors under (16) years.

The proposed training program has a positive and statistically significant effect at the level (0.05) on the functional efficiency of the lungs and the level of offensive skill performance (dribbling speed - passing speed and accuracy - shooting strength and accuracy) for handball juniors under (16) years old.

There are percentages of improvement in the post-tribal measurement of the basic research sample members in endurance of muscular capacity and functional efficiency of the lungs and the level of offensive skill performance in handball ranging between (11.58% - 83.33%).

Among the most important recommendations: Using the training program to develop muscular endurance because of its effectiveness in improving the functional efficiency of the lungs and the level of offensive skill performance for handball juniors under (16) years old.
