تقييم الدين اللااوكسجين بدلالة الكفاءة البدنية وتحمل الاداء والانجاز لفعالية 200م رجال

The main goal of the research know the indicators for the research sample through tests conducted by the researcher to know the oxygen demand and physical efficiency and for the purpose the effectiveness the 200 meters, where physical efficiency plays a vital role by delaying fatigue and speeding recovery for the research sample. Then came the research problem Through the researcher’s observation that there are cases of weakness in the physical efficiency index that are directly related to oxygen debt, as we notice that the deficiency in supplying the muscles with oxygen leads to a decrease in the level, which we notice directly through the increase in the pulse rate and thus it takes time for recovery. It is large enough to compensate for energy sources, which affects the level of achievement. The study included (12) players representing the Basra track and field clubs. The fourth chapter included tables and a discussion of the results, debt, fitness, physical efficiency, and achievement. The fifth chapter included, the most important of which is that debt is an indicator in track and field events, especially the 200-meter event, which means Religion and oxygen are an important in field events, especially the 200-meter event, which provides a clear picture of the player’s physical condition. As for the conclusions, studies and research should be conducted regarding physical efficiency, recovery time, and maximum Sunday tests for oxygen consumption, especially in the 200-meter event.
