The Study of Maximal Oxygen Uptake Anaerobic Threshold and Blood Component in Middle and Long Distance Runners

&nbsp;&nbsp;The purpose of this paper was evaluate the specificity of maximal oxygen uptake and anaerobic threshold which is indicator of cardio-respiratory function during incremental load exercise using treadmill, also.<BR>&nbsp;&nbsp;Twenty of elite middle and long distance runners participated as subjects of this research.<BR>&nbsp;&nbsp;By measurement the specificity of cardio-fulmonary function and blood component in middle and long distance runners, the conclusion and results which is obtained is as follows:<BR>&nbsp;&nbsp;1. Maximal oxygen uptake of absolute and relative value during maximal exercise load in middle and long distance runners was display 4.23±0.421/min &amp; 71.21ml/㎏/min, respectively, also, maximal ventilation and maximal heart rate was expressed 146±18.861/min &amp; 192.25±7.61beats/min, respectively.<BR>&nbsp;&nbsp;2. Oxygen uptake and relative percentage of maximal oxygen uptake in the anaerobic threshold levels of middle and long distance runners was shown 3.55±0.49l/min(46.54ml/㎏/min) 72.81±8.86%, respectively and ventilation, heart rate and relative percentage of maximal heart rate was expressed 95.09±16.95l/min. 176.54±9.79beats/min and 9l.62±3.90%. respectively.<BR>&nbsp;&nbsp;3. Concentration of plasma lactate(t-value:-3.65, p＜0.003), glucose (t-value:-4.52. p＜0.02) in blood component of middle and long distance runners was display the significantly difference between pre and post value after maximal incremental exercise load.
