Differences in response of respiratory system of middle and long-distance runners and their influence on the recovery rate

The work examines the main indicators of the respiratory system of middle and long-distance athletes-runners participating in international competitions. Using the device «Spirolab III» the comparative analysis of changes in the respiratory system of athletes during systematic performance of multidirectional loads in the training process has been conducted. Using the instrument, the test acceptability index has been calculated, the test quality control has been supervised and the results have been evaluated. The comparative analysis of the changes before and after the training session, the vital and forced lung capacity, the maximum free ventilation of expiratory capacity and the volume of forced breath for the 1st second has been undertaken. The survey has been conducted among the representatives of various types of running exercises, distributed into three groups - middle-distance runners (8 people), stayers (7 people), specializing in five and ten-kilometer run, marathon runners (7 people)...
