Special Exercises to Develop the Endurance of Speed and its Effect on Some Physiological Indicators and the Achievement of Running 1500 Meters

Abstract

The aim of the research is to prepare suggested exercises to develop the endurance of speed and the achievement of running 1500 meters for the members of the research sample and to identify the effect of using the proposed exercises to develop the endurance of speed in some physiological indicators and the achievement of running 1500 meters, and the supposed of the research was that there were statistically significant differences between the pre and post results for the control and experimentalgroups.The researchers used the experimental method in a controlled manner (experimental + control) for its suitability and the nature of solving the research problem, as this method is one of the most accurate, best and most efficient types of approaches in reaching accurate results, as the research sample was determined By deliberate selection, as the researchers determined the research sample,which are some of the advanced runners according to the classification of the International Association of Athletics Federations, as the research sample included (10) runners. They were distributed randomly (by lottery) into two control and experimental groups, each group consisting of (5) runners. The control group used the regular training method while the experimental group used the same old training way except endurance speed exercises It was prepared by the researchers and implemented by the assistant team. Physiological tests were conducted, including the maximum consumption of oxygen and lactic acid, and physical tests that included an endurance test of 1800 meters and an achievement test of 1500 meters on the members of the research sample. That Shows development of achievement by a large percentage, significant differences appeared between the two research groups in the post-test of variables.The concentration of lactic acid in the blood, the maximum oxygen consumption and the achievement of running (1500) was better in results for the experimental group, and that because of the special speed endurance exercises prepared by the researchers than the exercises used by the control group.
