The research aims to prepare exercises with different distances in the development of speed tolerance and the rate of concentration of hexokinase in the blood and the achievement of an enemy (200) meters under (20) years and to identify the effect of exercises with different distances in the development of speed tolerance and the rate of concentration of hexokines in the blood and the achievement of an enemy (200) meters Under (20) years, the researchers used the experimental research method and by designing the two equivalent control and experimental groups.

The researchers identified the research community in the Babil Governorate Clubs for Youth for a 200-meter enemy competition and four clubs, which officially participated in the championships held by the Central Athletics Federation 12 runners) They were divided into two groups, the experimental group, number (6), and the control group, number (6).

The researchers used a running test (170) meters withstand speed, a running test (200) meters and a biochemical test, and the researchers used the statistical bag (SPSS) to find the following statistical treatments and the arithmetic mean and median.

The standard deviation, the torsional coefficient, and the (T) test of the interconnected and unconnected sample.

The most important results: that exercises of different distances had a positive effect in the experimental group compared to the control, and that speed and achievement endurance exercises and the concentration of hexokinase enzyme among the subjects of the research sample resulted in They developed them in the tribal and posttest tests, and the researchers recommend the use of modern devices that measure physiological and chemical indicators in the field in codifying the training load, as they give a true indication of the reflection of training on the internal pregnancy, and interest in developing physical capabilities that bear the strength and strength characteristic of speed and explosive power that have a direct impact in the development of achievement in Athletics competitions for short distances.
