Research Summary
Physical education is an important field of public education, a stand-alone science that relies on many other sciences that contribute to the development of the process of learning various mathematical skills. Therefore, researchers in the field of physical education pointed out that sports psychology, teaching methods and dynamic learning are more important than The other sciences in learning in how to acquire the individual of the new motor skills and mastery well and with the least effort possible, has helped many factors on this development, including the means and methods of training and education used as well as educational techniques that have been subjected to studies and scientific research Especially the activities that are characterized by difficult motor skills, which is characterized by learning the performance of some ways to give an idea of skill and provide the correct model and division of that skill on steps with explanation and clarification in the complex parts of them. Hence the importance of research to know the impact of the method of inter- Learn the skill of jumping on the horse either the most important conclusions:
In the light of the researcher's findings, he concluded the following:
1. Fit the exercises used for the research sample contributed to their application correctly and appropriately.
2. The exercise has a positive effect on the development of the speed of the motor response to the effectiveness of horse jumping

The subject of exercises, educational aids and dynamic abilities occupies an important position in the gymnastics sport because of Its great effect on person’s love to the activities he will do it in the future that fulfill his desires and ambitions, which lead to raise the level of dynamic performance of various sports skills in the technical gymnasium characterized by its difficult performance Depends on the effort of the individual student in particular.
And this is the target of the research, the use of exercises using educational aids in the development of dynamic abilities and the performance of some technical Gymnastics and determine its good effect in developing the level of learning for students.
The research problem was that most of the technical skills of the gymnastics were difficult for the students during performance and weakness in the dynamic abilities which are important in showing the performance automatically. The objectives of the research were to present exercises using educational aids in the development of dynamic abilities and the performance of some technical Gymnastics skills for Faculty of Physical Education and Sports Sciences, University of Kufa , and to identify the effect of exercises using educational aids in the development of dynamic abilities and the performance of some technical Gymnastics skills for the same Faculty.
The two researchers supposed the existence of differences with statistical significance of the exercises using educational aids in the development of dynamic abilities and the performance of some technical Gymnastics skills for Faculty of Physical Education and Sports Sciences, University of Kufa
The two researchers used an experimental method, ( the method of two equal groups) on the students of the second stage in the Faculty of Physical Education and Sports Sciences, University of Kufa for the year 2017 - 2018,. The group was (23) students . They were divided into two control and experimental groups. Seven female students were chose for each of the two groups. The number of sample (14) students has been achieved and the process of homogeneity and equivalence in variables (fitness, flexibility, balance, open front roll, handstand, diving) has been identified.The technical skills and dynamic capabilities of Gymnastics which is used in the research were identified by a form of a questionnaire form for the identification , And was presented to (13) experts and specialists in order to identify the most important motor skills and basic skills were identified appropriate tests to measure the abilities of motor and performance assessment by three arbitrators of the skills in search and found the scientific basis for testing and testing tribal and the preparation of exercises using Or educational means and experience and the application of exploratory exercises and post-test statistical methods
The researchers concluded that the use of exercise using educational aids is more effective than the method used by the teacher in developing the dynamic abilities and performance of some skills in the technical gymnasium. They recommended to use of exercises using the educational aids of physical education, especially in learning the performance of skills in the technical gymnasium and similar research procedures on the other basic skills Technical and other stages of study

The research aims to:
- Build indicators of the relative weight of some parts of the body.
- Constructing equations to predict the level of achievement in the abduction level based on the indicators in snatching lift.
The researchers used the descriptive approach in the method of associative relationships as the best method for solving the problem of research. The sample consisted of (30) weight lifting players of the category of applicants، specifically the quartets participating in the Iraqi Weightlifting Championship for applicants in Baghdad، and the researchers used measurement، testing and personal interview as means To collect data، while statistical means included The mean، standard deviation، simple and multiple correlation coefficient and multiple regression analysis by reverse deletion method. Six relative weight indicators were established (thigh circumference index، hips circumference index، chest circumference index، arm circumference index، leg fat circumference indicator، shoulder width index ، Chest width indicator، hips width indicator) After the regression method was used for regression analysis، four significant predictive equations were obtained. The last equation was maintained on two indicators (the index of the circumference of the humerus and the circumference of the leg) in terms of their contribution to the level of completion at abduction height (0.441). Rather than the direct measurement of the ocean and the symptom، as well as their recommendation based on prediction equations obtained in predicting the level of achievement at the height of the snatching lift.

The study aimed to identify the effect of exercises similar to playing in the
development of sensory perception and speed of performance of the
planners of young football players. The sample included young players in
the Diwaniyah Sports Club for the season (2016-2017) and the number of
(20) players were divided into two groups control and experimental where
The experimental group was subjected to exercises similar to the 8-week
play with 3 units. The researchers concluded that exercises similar to those
used to remove control، receive balls under pressure and improve scoring
skills for young footballers

The research aims to:
1.Preparation of a proposed curriculum for the lesson of physical education taught in a comprehensive design approach to the development of some creative abilities of mobility and learning the skills of handling and handball reception of students in the fifth grade primary.
