The idea of the study lies in determining the effect of comparative competition method due to some kinematic variables on correcting and learning the skill again in a better way through correction of some performance errors in shooting from overhead by handball players. The researchers used the competition method as it is proper to the nature of solving problem of the study. The sample of the study was selected purposively (20 female students at the 3rd stage at Faculty of Sport Education, Diala University as they learned this skill in previous stages. 10 students were eliminated (6 for the exploratory trial and 4 not conforming with it). The researchers used this method which included the number of educational units by preparing the skill of shooting from overhead for the sample of the study. Results showed that this method has a positive effect on correcting errors of the skill due to mechanical variables determined by the researchers serving to solve the problem o the study and based on scientific research and biomechanical academies. The study also found improvement in skill learning and development in handball through extraction of statistical results by applying the Statistical Package of Social Sciences (SPSS) program.

The world witnessed a great progress at all aspects and fields of life including sports field with rapid pace. This is clear through incredible results and records in these sport games and events. Cycling events (Race against Time) are the concern in this study in terms of applying a training course according to the nonoxygenic energy system needed for such events and the effect of this training course on developing some functional, skill and physical variables. This training is performed at the special preparation stage of cycling national team players. The application of these exercises is made on young players, and this age category gives accurate expression of any course to be applied on. In addition, energy economy during physical effort reflects positive sides in the adaptation processes of cardiac and circulatory systems, especially at the level of the heart in terms of heart muscle recovery, fast restoration and continuity of blood pumping with the same efficiency and spent energy.

The researchers aim to find the differences in the results of the post- test between the two groups the experimental and setting group in learning some or the Movable skills lie wrestling. The searchers used the experimental course because it fits the nature of the research and its problem. The group of the research was from the students of the second stage in the collage of physical education - Duhok university, the academic year {2014 - 2015}, while the sample of the research was formed from (24) students divided in two sections [B , D] in two groups experimental and setting, there the searchers made the equalization operator for the two groups of the research. The searchers depended on the personal interview and question ring also the tests and measuring at a used methods for, gathering the data, the searcher used the arithmetic mean, and the quantities deviation also the percentage and (t) for the non - concerned samples at methods for getting the data. The searchers concluded that the experimental group achieved more better learning better than the setting group in the skills of [The Inside same (turk ride) catch, near leg pick - up and inside leg block catch, and Throw over the hips with an arm and waist hold catch and Takedown by head drag catch], also the two groups never achier way differences in the skill of the [Throw over the hips with an arm and waist hold catch] in wrestling, the searcher’s recommended in using the interactive video in learning some wrestling skills, while teaching the subject of wrestling for the students of the physical education college.
