目的是检查高压氧（HBO 2）治疗对a）长时间运动后恢复和B）训练人群有氧运动能力的急性影响。受试者为6名男性和6名女性，接受过训练的跑步者，平均Vo2max值分别为64.6 +/-5.6和51.9 +/-6.6 ml x kg（-1）x min（-1）。受试者以随机顺序进行四种运动-HBO2条件：a）对照，B）运动-无HBO2，c）无运动-HBO2;和d）运动-HBO2。运动是一个90分钟的运行在75 - 80%VO2max x HBO2治疗包括呼吸95%O2在2.5大气压绝对值为90分钟。在每个条件结束时，有氧性能进行了评估与VO2max测试和在跑步机上运行在三个次最大速度的氧成本。在2.5 atm绝对压力下单次HBO 2治疗90 min后，恢复没有增强，也没有改变次最大或最大跑步性能。
The purpose was to examine the acute effects of a hyperbaric oxygen (HBO2) treatment on a) recovery following prolonged exercise and b) aerobic performance in a trained population. Subjects were six male and six female, trained runners with mean Vo2max values of 64.6 +/- 5.6 and 51.9 +/- 6.6 ml x kg(-1) x min(-1), respectively. Subjects performed four exercise-HBO2 conditions in random order: a) control, b) exercise-no HBO2, c) no exercise-HBO2; and d) exercise-HBO2. Exercise was a 90-min run at 75-80% of Vo2max x HBO2 treatments consisted of breathing 95% O2 at 2.5 atm abs for 90 min. At the end of each condition, aerobic performance was assessed with a VO2max test and by the oxygen cost of running on a treadmill at three submaximal velocities. Recovery was not enhanced following a single HBO2 treatment at 2.5 atm abs for 90 min, nor did it alter submaximal or maximal running performance.
