Articles : Effects of Intermittent Hypoxic Exposure on Cardiopulmonary Function and Oxygen Transporting Capacity in University Basketball Players
Abstract
The purpose of this study was to propose types of hypobaric hypoxic training for cardiopulmonary function and oxygen transporting capacity. Eighteen university basketball players were divided into H.L group (Living High & Training Low, n = 9) and L.L group (Living Low & Training Low, n = 9) according to hypoxic exposure. Oxygen transporting capacity, body composition, maximal oxygen uptake, blood lactate concentration, cardiopulmonary function and heart rate were investigated. Results were as follows. 1. There was no significant difference on body composition inter group or among several test time. 2. After exposure, heart rate was significantly low in H.L group. And there was significant difference inter group or among several test time. 3. Maximal oxygen uptake was significantly high by exercise time increase but there was no significant difference inter group or among several test time. 4. Blood lactate concentration was increased after exposure but there was no significant difference inter group or among several test time. 5. According to training period increase, there was no significant difference on RBC, EPO but Hct, Hb concentration were significantly lower than after Iweek exposure. But there was no significant difference inter group or among several test time. 6. In hypobaric hypoxic environment, heart rate during sleeping was significantly decrease as time goes by. 7. In hypobaric hypoxic environment, oxygen saturation during sleeping was significantly increase as time goes by. As a result, passive exposure in hypobaric hypoxic environment was not significantly efficient on body composition, blood component and blood lactate concentration but heart rate during exercising and sleeping was significantly low and exercise time and maximal oxygen uptake increased. It could be a possibility.
Key Words: Hypoxic exposure, Cardiopulmonary, Function oxygen transporting, Basketball player
