Abstract EN

- Research Summary: The study aimed to identify the contribution of the momentum of some parts of the body in the amount of movement in the stage of upgrading in the long jump in the youth, and mentioned some of the main axes related to the variables of the study, the researcher adopted the descriptive approach to study the correlation relationship, (12) athletes in the field of athletics, y showed that there is a significant correlation between the variables of the study (angular momentum of the trunk, angular momentum of the thigh, angular momentum of the leg) with motor flow, and recommended the researcher to emphasize the trainers training large blocks in the body for proportion between the parts of the body during the performance of the motor duty, Exercises on leg strength and weighted exercises for the leading man through rubber cords, and emphasizing the use of imaging and kinetic analysis in order to identify the strengths and weaknesses in the movement of body parts during the performance of a long jump athlete and emphasize the technique.

- key words: (Momentum of body parts, amount of motion, stage of elevation, long jump, emerging).
