ABSTRACT

Shin, C. H., Cho, S. Y. Effects of Intermittent Hypoxic Training on Cardiopulmonary Function and Blood Parameter in Elite Swimmer. Exercise Science, 12(2): 223-232, 2003. Intermittent hypoxic training refers to the discontinuous use of normobaric or hypobaric hypoxia, in an attempt to reproduce some of the key features of altitude acclimatization, with the ultimate goal to improve sea level athletic performance. This study was designed to determine changes in cardiopulmonary function and blood parameter following intermittent hypoxic training in elite swimmer. The subjects were randomly assigned to either a normoxic(N=8) or a hypoxic(N=8) training group. Training involved 4week of treadmill exercise inspiring normoxic(FIo2 = 20.9%) or a hypoxic(FIo2 = 15%; about 2500m altitude) gas, respectively, in a double blind manner. Treadmill exercise was performed five times a week for one hour at about 70% of maximum heart rate determined either in normoxic and hypoxic training group. Four weeks after training in hypoxia, significant increases were seen in all important parameters of the cardiopulmonary function and blood factor. A significant increase of 4.4% on HTG was seen in the Vo2max and the VEmax increased significantly by 9.6%. on HTG and 6.7% on NTG. The blood parameter(RBC, hematocrit, hemoglobin) were significant increase only HTG. The results of this study indicate that intermittent hypoxic training can improve both cardiopulmonary function and blood parameter.
