| ABSTRACT |
|
This study was designed to investigate the effect of short and long duration intermittent normobaric hypoxia training on breathing gas, blood lactate concentration, blood acid-base balance, performance in submaximal bike exercise every two weeks during six weeks. For the purpose of this study, male collegian trained in 16.5%O2(Experimental group: E) and 20.93%O2(Control group: C) during six weeks. Also, all subject estimated in breathing gas, blood lactate concentration, blood acid-base balance. As a result, workload(C: 20.7%, E: 29.1%) and time to target HR significant improved. Clearly improvement of time to target HR presented 2-4 weeks training duration in E. Also, concentration of HCO3- in exercise decreased followed training but change of pH don’t presented. These results thought normobaric hypoxia training decreased HCO3- throughout improve compensation of metabolic acidosis because enhancement of hypoxia ventilator response that CO2 elimination in breath during exercise. Therefore, sea level exercise performance increased within 2-4 weeks training through 80%HRmax intermittent exercise training during 60min in 16.5% normobaric hypoxia (2,000m altitude). |
