Running leads to change the blood ingredients in different rates. These changes came within the physiological and biochemical conditions that occurred to face the physical exercises effete with the different training doses. Of these changes the sugar –blood ratio which came within the bodies response , and for the low concentration on the physiological and biochemical basis in setting the training programs for the athletes , and for the important role of this issue to get the highest achievements by the athletes as a result of developing their physical and physiological abilities , it became necessary to search and study the effete of running with different energy systems on the sugar ratio in the athletes blood according to scientific basis to get integrated physical characteristics and elevated scientific competence and to develop their physical systems . The experimental method had been used in this study – the equivalent group on a sample of nine runners who had been chosen deliberately and the researcher used the suitable statistical methods to deal with the results , and throughout these results the researcher get the following conclusions ;-1-There are significance differences between the before and after training testing for the second group of the (1500 m) runners , and the third group of the (5000m) runners , and the advantage is for the other training test relating their sugar – blood ratio .2- There are no significance differences for the first group of the ( 100m ) runners relating their sugar –blood ratio .
