Juggling is considered as a basic technical skill which is often ignored by soccer coaches. It provides players with the ability to control the ball after activities such as corners, free-kicks, goal-kicks, throw-ins, and crosses. Furthermore, juggling improves their coordination and balance abilities. Due to the fact that there is not any systematic study for juggling evaluation with gradual difficulty the current research project aims to develop a battery of juggling tests with increasing difficulty. In addition the researchers include movements which are similar to the game conditions such as zig zag, jumps and various body contacts. In the current study forty four players participated, twenty two of which were experienced soccer players and twenty two were recreational athletes. The results confirmed the reliability and validity of the tests. Furthermore, it was found that the difficulty of the tests was gradually increased when the researchers added limitations regarding time, distance, and contact surfaces.

The representational systems can be defined as the ways that are favored by learners in receiving and processing information and interact with them as a technique or style to resolve the problem or situations that they face. While the self-efficiency is defined as knowing one's own expectations and ability to overcome the various tasks successfully, and self-contentment and ability to control and overcome the difficult problems that he is facing..In speaking about the researcher's experience as being an instructor in one of Kurdistan universities she found that there are differences in the self-efficiency between practitioners and non-practitioners of sports in the educational institution. Therefore, she decided to conduct a study on representational systems and their relationships with self-efficiency , Thus, the research aims to recognize the favorite representational systems and the self-efficiency of the research sample depending on the variables (gender, academic specialization)..The research sample consisted of (336) students from both practitioners and non-practitioners of the students of sports from (scientific, humanitarian and Physical education) departments. The scale of representational system has been built and the scale of representational systems has been built and the psychometric features has been verified and took out its validity and reliability. Then the researcher applied the two scales on the basic sample of the research and copied the data and processed the results statically. The study results:.The practitioner students of sports of Physical Education prefer the representational system (kinetic sense) on the rest of the systems, while the non-practitioners of the students of sports prefer the representational system (visual) on the rest of the other systems, besides, the practitioners of sports outperform the non-practitioners in the self-efficiency morally. The research aims: 1.Recognize the favorite representational systems and the self-efficiency of the research sample depending on the variables (gender, academic specialization). 2. Recognize the significance of the statistical differences in representational systems and self-efficiency of the research sample depending on the variables (gender, academic specialization). 3.Recognize the relationship between representational systems connectivity depending on variables (gender, academic specialization) and its relationship with self-efficiency of the research sample. The researcher used a descriptive survey method and the sample consisted of (336) students from both practitioners and non-practitioners of the students of sports from (scientific, humanitarian and Physical education) departments. To achieve the objectives of the study a scale of representational systems has been built and the researcher verified the psychometric features of the scale and took out its validity and reliability. Then the researcher applied the two scales on the basic sample of the research and copied the data and processed the results statically. The study results revealed a number of conclusions, including: *Sport practitioners who are students of physical education prefer representational system (kinetic- sense) on the rest of the systems then visual, audio systems. *Non-practitioners who are students of scientific and humanitarian departments preferred the visual representative system than the rest of other systems followed by the kinetic-sense system then audio sense. *The practitioners of the sport Out-perform a non-practitioner in self-efficiency internally. *There is a morale relationship with between the representational systems (visual and kinetic-sense) from one side and self-efficiency from the other side. Key words: Representational systems, self-efficiency, relation, practitioners, non-practitioners of sports

This work aimed to elicitation the speed of swimming computing the time of performance divided on the distance. Therefore, the speed meaning their achievement and thereafter understanding the relationship between kinematic variables and achievement that lead to final focused recommendations using descriptive method, samples of sixty students were selected intentionally from forth year, school of physical education, Duhok with good performance in swimming. Scientific observation, questionnaire, test, analysis, and measurement were used for data collection, certification of the scientific observation was carried out by two camera one above and other under the water inside glass box closead tritely placed in front of the performance (10 m in the middle of race). The best photos transferred to laptop for application Maxtraq program for kinetic analysis. Results revealed non – significant correlation between some biokinetic variables with achievement i-e weakness of sampling technique. Free-style swimming requires body's extension through extending of hips which showed significant correlation with achievement. Comparable correlation of elbow with achievement means necessity of hand extension to pull more water. However, increasing of leg extension when the right arm enter the water lead to less resistance on the body. Once the right arm enter water, the left hand must gradually extending under water until approach to full extension beside the hip. Thus, inverse considerable correlation resulted between leaf forearm with horizontal line of body Key Words:-Bio Kinematics, Achievement, free style, swimming

Research objective: Studying the vertebral column morphology in the thoracic , lumbar & sacral sections as well as identifying the incidence of scoliosis in tennis players. Research Sample: 15 players from Sultan Qaboos University tennis Team were chosen by the selective method. Research Methodology & Material :The Spinal Mouse device was used to evaluate the vertebra using descriptive methodology. Research Procedure: Six tests in three positions (Standing ,Flexion and Extension) were done to simulate the physical performance of the sport.Statistical evaluation suitable for the study were used :mean, standard deviation, Spermann and Person correlation factors . Research Results: A higher mean difference in the lumbar areas in the flexion position 48.73 degrees in comparison to the thoracic and sacral area. Meanwhile a higher mean difference for the thoracic and sacral area in the extension position 26.06 & 40.73 degrees consecutively confirmed by Spermann and Person correlation factors. There was no scoliosis in the sample. Research Recommendation: Focusing on strengthening exercises of the abdominal and lower back muscles ensuring the efficacy and stability of the vertebral column. Keywords: different positions - tennis performance - vertebral column morphology

The significance of the paper is in studying the variable (psychological-personal-emotional compatibility) as it is regraded of the factors which influence the nature of performance, acclimation and goals achievement in harmony with the reality of the society he lives in as well as the importance of the individual's self-apprehension and the ability to know the capabilities and potentials of the individual himself to be able to interact with the different bodily, skillful, and cognitive sides in compatibility with the behavior of the individual along with his activity and level of performance. The researchers adopted the descriptive approach of associative relations. The scale is adopted to (70) players representing (53.84%) of the total study society. While the final scale is applied to (50) players representing (38.46%) of the original society. In this way, the adaptation sample and final scale sample of (120) players in a ratio of (92.30%) of the original society. The level of sportive psychological-personal-emotional compatibility was good in the sample of the study. Any improvement in the level of sportive psychological-personal-emotional compatibility will lead to a development in the skillful performance and vice versa. This encourages other researchers to work on similar studies dealing with other skills, other sports and different samples in various study levels even in terms of the gender of learners.
