The impact of Using Trampoline Apparatus on Some Physical Abilities and Level of Performance of Gumps in Rhythmic Technical Exercises for Female Students of the Faculty of Physical Education in Mansoura

The study aims to identify the effect of using the jump ladder and trampoline Apparatus on each of thedevelopment of the relative muscle strength, the development of the ability of vertical jump "work" and the raise of performance level of the female students in each of the gap jump and the arch jump. The researcher used the experimental approach through the experimental design of the two experimental and control groups and their number is (40) female students of the first year, each group consists of (20) female students, and the most important results refer that the use of two jump ladder and trampoline Apparatus helped to develop the relative muscle strength and the development of the ability to jump and they helped to raise the level of performance of the two gap and arch jumps.
Second: Foreign Studies:
1- Study of SandersHir 1995 (26) entitled ". The study aims to know the impact of the ability on the method of turnperformance around the longitudinal axis of the frontal air turn on the trampoline, and he used the experimental methodfor one group of (11) elite trampoline players and he used a program for purposive exercises on the trampoline device, the period of program was (8) weeks by 5 units per week. The trampoline has a positive impact on the ability to perform turn around the longitudinal axis.

Research Methodology:
The researcher used the experimental method using the experimental design method, which has post and pre
measurement for two groups, one of which is an experimental group and the other is a control group.
Research population and sample:
The research's population represents the female students of the first year in the Faculty of Physical Education at Mansoura University for the academic year (2016- 2017AD).
The sample was randomly selected and thebasic sample number was (30) female students. They were divided into two groups, one of which is experimental group and it consists of (15) female students. The proposed program was applied using trampoline and a control group of (15) female students and the program followed by the faculty has been applied. A pilot sample of (20) female students has been chosen randomly from the research's population from outside the basic sample to find scientific coefficients and pilot experiments on them.
Homogeneity and equivalence between the research groups are shown in the basic, physical and skill variables.
