Many scientific research and documentation of medical bodies indicate that the practice of physical activity on a regular basis are associated with many health benefits and is beneficial to the functions of the various organs of the body , people differ among themselves in terms of mental abilities , personality traits , and standards of physical and preparations , tendencies , trends , and the ability to physical performance ,And when we try to explain these differences and we measure and characterize it, we do so we have We put the phenomenon of individual differences for study and research. Individual differences be either in character type, or in the degree of the existence of such, through the views of some schools to some schools high school during the period of supervision of the students of the fourth phase in the material Tabiq researcher noted the existence of individual differences for some physical measurements, especially in the reconstruction following the primary stage, a stage of adolescence which is one of the most important stages of building physical and configured Farad researcher find out the cause of these differences and do physical activity role in the configuration of physical characteristic that leads to such a difference.The purpose of research to identify the individual differences between practitioners and non- practitioners sporting activity through the shape profile measurements of the physical network , the research sample included students study elementary, middle and they are not practitioners of sports activity was selected as the school career of Khanaqin babes practitioners of sports activity, Underwent physical measurements ( main experiment) 8-11 / 2/2015 was taken (15) compared to physically between the lengths of the oceans and the thickness of fat and after processing the data statistically researcher concluded that there is excellence in physical measurements and in favor of practitioners of sports activity , the researcher recommends worthwhile lessons Sports primary and secondary schools because of their importance for the proper strength as a researcher recommends further research of other age groups.

This study asserted the importance of motor expectation as it is closely related to serve reception skill considering correct reception as the key to gain points.

The purpose of this study was to determine the effect of coffee ingestion on anaerobic performance of coffee drinkers. Wingate bicycle tests were applied before and after 10 days coffee consumption. In a randomized and double blind design, one group of subjects consumed coffee (3 mg caffeine/kg/day) and other group of subjects consumed decaf coffee for ten days between two Wingate tests. Wilcoxon Signed Ranks Test test were applied between pre and post-tests of the group. Effect size (ES) was calculated using Cohen’s delta to evaluate the size of mean differences. Results of this study indicated that peak power increased in just caffeinated coffee group when compared to baseline (p<0.05). As a conclusion it can be said that long time coffee with caffeine ingestion has a positive effect on anaerobic performance
