The effect of anaerobic exercises with a critical speed index for the effectiveness of 200m and some physical and functional abilities of the class (46 T, T47) in the second special preparation stage

Abstract

The introduction and the importance of the research lies in the role of short anaerobic phosphogenetic exercises using the critical speed index in the effectiveness of running the 200m, that the critical speed exercises work on developing the physical physiological and biochemical capabilities and energy systems that dominate the specialized activities and increase the development in the level of balance of functional conditioning using a modern method in determining times And the timings of running for the specified distances in order to reach the target time through accurate training and emanating from the use of less distances and higher training stress to develop the level of some physical and functional abilities. As for the research problem, it lies in the weakness and low level of the critical speed of the critical final stage in the 200m race ((the final stage of the race, which arises from the weakness and low phosphoric and lactic ability within the concept of short anaerobic work (T46, T47).And the research sample consisted of 6 national team players in the event of running 200m. The physical tests and the job were determined, especially in the research. An integrated training curriculum was used for two months in the second special preparation period, and tests were conducted for the research, and good results were reached in the level of functional and physical abilities and the critical speed rate for runners. He reached the most important results:

• Critical speed exercises within the phosphatic and lactic acid work have a clear effect on the rate of speed and endurance of the maximum speed in the effectiveness of 200mThe short tactical ability exercises are more important and effective in achieving the level of running time of 200m
