Development of the percentage of oxygen, lactic production in the blood and vital capacity for swimmers

Gomaa M. Othman

The research aims to identify the effect of the development of lactic production on the level of oxygen in the blood, Vital-capacity and swimmers speed, The researcher measured the concentration of lactic acid in the blood, vital capacity and the speed of the swimmers and used SPSS in order to obtain : Arithmetic Mean, Standard derivation, T-test and Sekwness, Correlation coefficient. The swimmers speed improved as a result of increased lactic production in the blood, improved vital capacity and oxygen level in the blood.
1. Increase the interest of trainers in the physiological measurements represented in (lactic blood ratio, blood oxygen level, vital capacity, etc)
2. The necessity of relying on measuring the concentration of lactic in the blood to assess the training status of swimmers.
3. The need to use physiological indicators for swimmers in designing and preparing training programs appropriate to their physiological abilities.
