摘要：The author estimated the O_2 requirements from the average time of each races and speed-O_2 requirement curve in running and swimming races in Japanese senior high-school athletes who are ranking players. The O_2 requirements of similar race time, were less in swimmers than in runners. The O_2 debt and alveolar O_2% after races, were less in swimmers than runners and dlveolar CO_2% of is larger in Swimmers than runers. It was confirmed that the lung ventilation was limited due to water pressure and spcifrc inspiration movement. It was demonstrated that the inhalation of O_2 before the race could shorten the records in short distance swimming races.
