This research aims to Know The effect of using Functional training exercises on some physical abilities, lower limb kinematics, and skill level performance on le Petit Echappe´ in ballet by developing a set of functional strength training for skill chaos Le Petit Echappe' in ballet. And knowing the extent of its influence on the level of performance of the skill Le Petit Echappe in ballet using dimensional measurement. and identifying the percentage of improvement in the skill of Le Petit Echappe in ballet in both components of functional strength and kinematic parameters, The primary study sample was chosen intentionally from the fourth-year students at the Faculty of Physical Education Boys - Girls in Port Said and the sample included (5) students, and the researchers used a number (22) students from the same study community and outside the basic study sample, including (20) students to conduct Scientific transactions (honesty - consistency) of the tests used, as well as two (2) students to conduct the exploratory study to codify the training loads for the proposed job strength training, the most Conclusions was Determining the kinematical parameters for performing the Le Petit Echappe´ skill in ballet. and Improving the components of the job force to perform the "Le Petit Echappe´" skill in ballet, as a result of applying the suggested job strength training to the study sample.
