본 연구는 최대 운동 후 산소 농도를 달리한 회복법이 생리적 피로 요인에 미치는 영향을 알아보기 위해 남자유도선수 10명 대상으로 탈진적인 유산소운동을 실시 후 1차 실험에 대기산소 농도와 같은 21%, 2차 실험에 30%, 3차 실험에 90%의 고농도산소를 15분씩 섭취 시켜 안정시, 운동후, 회복 30분, 회복 90분에 혈중산소농도, 혈압, 젖산, 암모니아를 검사한 결과 혈중산소포화는 산소 농도 30%와 90% 집단이 21%집단에 비해 회복 90분더 높은 혈중산소포화도를 보였으나 유의한 차이는 검증할 수 없으며, 수축기 혈압과 이완기 혈압 모두 산소농도를 21%, 30%, 90%로 달리 하여 섭취한 결과 유의한 차이는 검증 할 수 없었다. 젖산은 회복 30분에 산소농도 90%집단이 21%와 30%집단 보다 낮으나 집단간 유의한 차이는 검증할 수 없으나, 집단과 시기 간에 상호작용은 있는 것으로 나타났다. 암모니아는 최대운동 후 산소농도를 21%, 30%, 90%로 달리 하여 섭취한 결과 유의한 차이는 검증 할 수 없었다. 최대운동 후 휴식시 섭취하는 고농도 산소는 젖산에서 나타난 집단과 시가간의 상호작용을 나타내었으나, 산소농도차이에 따른 혈중산소농도, 혈압, 암모니아의 유의한 차이는 발견할 수 없었다. 이러한 원인으로는 평소 고강도 훈련을 실시하는 유도선수들임으로 신체 에너지 보유량이나 회복능력이 빠른 점과 본 연구에서 측정한 혈중산소농도, 혈압, 젖산, 암모니아는 운동 후 빠른 대사가 이루어져 유용한 변화를 검증 할 수 없었을 것으로 생각되어진다.
Abstract
In this study, blood oxygen concentration, blood pressure, lactic acid, and ammonia are investigated at the states of stable, after performing exercise, recovery for 30 minutes, and recovery for 90 minutes by applying highly concentrated oxygen of 21% as the same as atmosphere oxygen concentration in the first experiment, 30% for the second experiment, and 90% for the third experiment after performing exhaustive aerobic exercises for the subjects, 10 male Judo players, in order to investigate the influence of a recovery method that varies oxygen concentrations after completing maximum exercise. In the results of this investigation, although the groups that apply oxygen concentrations of 30% and 90% represent higher blood oxygen saturation than the group, which applies oxygen concentration of 21%, for the recovery for 90 minutes, it is not possible to verify their significant differences. Also, it is difficult to verify the significant difference in the blood oxygen saturation according to the change in oxygen concentrations, such as 21%, 30%, and 90%, for systolic and diastolic blood pressures. In the case of the lactic acid, although the group that applies oxygen concentration of 90% shows lower oxygen concentration than the groups that apply oxygen concentrations of 21% and 30% for the recovery for 30 minutes, it is not possible to verify a significant difference between groups. However, there are some interactions between the groups and the times. In the ammonia, it is difficult to verify the significant difference in taking oxygen by varying its concentrations, such as 21%, 30%, and 90%, after performing maximum exercise. In addition, there are no significant differences in oxygen intake concentrations at a recovery period after performing maximum exercise as well as blood oxygen concentration, blood pressure, lactic acid, and ammonia. The results are due to the fact that Judo players have a high physical energy level and a fast recovery rate because they have high intensity training in their normal times. In addition, it is considered that the verification of the significant change in some factors measured in this study, such as blood oxygen concentration, blood pressure, lactic acid, and ammonia, is difficult because such factors represent fast metabolism after performing exercise.
