The idea of the research lies in two proposed training courses for developing the personal physical aspect based on high intensity interval training method and with the rotational technique for handling individual differences through the two techniques of control (time & reiteration) the researchers have applied- in both courses- the level card concerning each player taking into account the individual differences among the players in order to reveal physical levels of each player and progression between a single medium session and the one that follows.
The research has aimed at revealing the following:
1. The statistical significance differences between the two techniques of controlling load and reiteration duration time in a number of physical and skilful variables of the post test.
2. The change ratios in certain number of physical and skilful variables regarding the two controlling techniques of young football players.
Through these two objectives; two hypotheses have been established as follows:
1. Significant differences have been found between the two techniques of controlling load and reiteration duration time in a number of physical and skilful variables of young football players in post tests and in favor of ( the technique of controlling load duration time).
2. There has been a difference in the change ratios regarding a number of physical and skilful variables between the two techniques of control among young football players.
The experimental methodology was applied for its convenience with the nature of the research and the two training courses have been conducted on a sample of (20) young football players aged (16-19) from Ninevah football club chosen intentionally and randomely divided (by lot) on two experimental groups in the amount of (10) players for each group. Research procedures have included designing two proposed training courses to control the load volume, one of which represented by (controling the time of load duration) and the other is represented by (controlling the load volume) as well as carrying out a number of pilot experiments. Procedures also included pre physical and skilful tests. Before starting the course, the five constant exercises' maximum values throughout the two courses were identified and registered in the level card concerning each player. Execution period of the two courses has lasted nine weeks in the amount of three training units in each short session. Finally post physical and skilful tests were carried out.
The researchers have applied the following statistical means:
(arithmatic mean, standard deviation, Person's simple correlation coefficient, percentage, t-test for independent samples, t-test for correlated samples and change percentage).
The following conclusions were attained by the researcher:
1. The technique of controling load duration time has achieved progression in the arithmatic means rearding all the physical attributes (abdomen speed-deferentiated force, legs' force endurance and flexibility) beter than the technique of controling load reiteration at comparing the findings of post physical tests in favor of the technique of controlling load duration time.
2. The technique of controling load duration time has achieved progression in the arithmatic means rearding all the physical attributes (the accuracy of remote scoring, the accuracy of the long pass and stopping the ball) better than the technique of controling load reiteration at comparing the findings of post skilful tests in favor of the technique of controlling load duration time.
3. There has been a varied difference in the change percentage of all the physical and skilful variables (abdomen speed-deferentiated force, legs' force endurance, flexibility, the accuracy of remote scoring, the accuracy of the long pass and calm down). This change was in favor of the technique of controlling load duration time.
4. the attribute of flexibility has achieved the highest difference in the change percentage in favor of (the technique of controlling load duration time).
The researchers have recommended the following:
1. The potentiality of applying both techniques according high intensity interval training method and by the rotational technique and the level card that are based on scientific bases in developing the physical aspect as well as the skilful level of young football players.
2. Using the level card in the training courses for its impact on realizing the differences among the players' levels.
3. The need for using the rules of high intensity interval training method when developing ((abdomen speed-differentiated force, legs' force endurance, flexibility).
4. The need for including the attribute of flexibility during the in-between rest periods in the training courses for the evident pregress it has achieved.

Abstract
The amount of movement has a significant impact on the achievement during the stage of takeoff in the long jump as a jumper in good performance in order to achieve the highest level of achievement and this requires the jumper to involve all segments of the body in performance. The research aims to identify the percentage contribution of the momentum of the body segments of the momentum the total for the body to the stage of takeoff of the long jump. And to identify the relationship with the momentum of the body and body segments with the level of achievement.
The researchers hypotheses that there is disparity between the proportion of the momentum of some segments of the body of the momentum overall in the stage of Takeoff of long jump, researchers used the descriptive approach is adequate to the nature of the research. The sample consists of (6) Jumpers of those who received the first six position in the Iraqi Championship, which was held on the Stadium of Arbil, sports Club, and in order to reach biomechanical analysis the researchers used video imaging and the following programs: I Film (Edit 1.3), Adobe Premier (6.5), ACD See (10), Photo Manager, Auto CAD (2007) and Microsoft Office Excel (2003). The researchers used statistical tools such as the following: The mean, standard deviation, simple correlation and the percentage of contribution.
The researchers found that the momentum of the trunk came in first place by a contribution of (0.985), and then came the head in the second by a contribution of (0,953). While the leading leg came third with a contribution of (0.938), after that the takeoff leg came fourthly with a contribution of (0.803) , While the arm that is contrary to the leading leg came fifth with a contribution of (0,749), finally came the arm that is contrary to the takeoff leg with a contribution of (0.080).

The Introduction and the importance of the research:
Volleyball is considered one of the ball games in special and a team game in general which is included in the general framework of the sport activities for most of the countries developed in the field of sports as this game become characterized by the dynamic which leads to a high level of excitement especially when practicing the requirements of the game, because there are a variation in its kinetic rhythm and that is clear through the kinetic variety, and this entailed the necessity of creative abilities harmony which get in accord with the required performance during the real contest. (Hasan, 1998, 9)
The technical skills are the movements that should be performed by the player in accordance with the circumstances required by the volleyball game in order to reach positive results, saving the physical effort and delaying the state of tiredness for the players and that is the reason behind mastering them completely.
The players should perform all the basic skills in an equivalent level so that each player can accomplish his duty during playing.
So, it is important to analyze the technical skills into their stages in order to be learned easily and accurately taking into consideration the law of the game. Despite the fact that the skills seem to be easily performed, but they require a great deal of effort in order to master them according to the law of the game represented by the short time of touching the ball, identifying the touching of the ball, the small size of the field and the flying speed of the ball and other aspects.

Abstract
Researches had been directed towards the barbell trajectory of the weight as an indicator to the performance and actual expression to the range of weight lifter biomechanical capabilities. Several studies have been conducted on snatch lift; they almost depended on the amendments done by (Roman & Chakirzenove) in treating jump issue among weight lifters predominantly forward and backward. This were studied by using the amount of total jump distance according to the direction of jump in deviation variables (D2-D3-D4-D5-D6), as the distance during the jump has never been passed usually by the weight lifters, the researcher sought to measure the actual distance on each variable and amended the values of weight deviations (D2-D3-D4-D5-D6), the error measurement may be well-deserved to reach to the real values of these deviations.
The current paper aimed to:
1. Identify the values of weight deviations in snatch lift by two methods of (Roman and Shakirzenove) for the amended line of jump issues and the proposed method.
2. Identify the differences in weight deviations in snatch lift between the two methods of (Roman and Shakirzenove) and the proposed one to the amended line for the jump issues.
3. Identify the values and differences in jump distance between the two methods of (Roman & Chakirzenove) and the proposed method.
4. Identify the relative change of weight deviations in snatch lift (Roman & Chakirzenove) and the proposed method of amended line of jump issues.
The researcher proposed that:
1. There are significant differences in values of some weight deviations and the jump distance in snatch lift between two methods of (Roman and Shakirzenove) and the proposed method to the amended line for the jump issues.
2. There is variance differences of relative change in the values of weight deviations in snatch lift between (Roman & Chakirzenove) and the proposed method of amended line of jump issues.
Materials and Methods included:

Abstract
Background: Tennis elbow is the commonest example of traumatic tendon disease of the elbow; the causes may be due to the repeated stress, which could come from motions in sport or at work. The patients may complain of ache in the area that is present at rest or at night after activity. Different treatments as iontophoresis, ultra sounds, post isometric contraction relaxation and advice concerning in a proprial use of the hand extensors muscle.
Aim: to evaluate the most beneficial of the previously mentioned treatments in tennis elbow patients.
Patients and Methods: thirty six patients (25males and 11 females), most of them are nonathletic (83.3%), their age range from 22-56 years (mean value=35±110), who were clinically diagnosed as tennis elbow by an orthopedician or physiotherapy seniors. They were referred to the physiotherapy unit at Azadi hospital in Duhok city, Kurdistan region, republic of Iraq. The study period was dated from 1st March 2007 to 1st April 2009; the patients were divided into two groups, group A (18 patients) treated with local Dexamethasone Phosphate injection (4mg), group B (18patients) treated with Dexamethasone Phosphate iontophoresis (4mg), the follow up of the patients was started after the initiation of treatments by one week and monthly continuo for 6 months.
Results: Patients in group A and B showed good response to local Dexamethasone Phosphate injection and Dexamethasone Phosphate iontophoresis 94.4% and 88.9% respectively. While 5.6% and 11.1% of the patients did not respond to the same treatment regime in group A and group B and they need surgical interference.
Conclusions: Iontophoresis is not superior to local injection with Dexamethasone, but it is preferable for their characteristics, as being non-invasive, non traumatic, less painful and safe technique.
Key words: Tennis elbow, Lateral epicondylitis, lateral epicondylalgia, iontophoresis, local injection.
