目的 :探讨高压氧对长跑运动员急性疲劳恢复过程的影响。方法 :1 8名健康男性长跑运动员 ,随机分为高压氧组、高压空气组和常压空气组 ,每天一组长跑 2 5km。在长跑前、长跑结束后即刻、吸高压氧后以及恢复后期测心率、血尿素氮和血乳酸及记录主观疲劳感。结果 :长跑结束后所有受试者心率均增至 1 75次 /分以上 ,血尿素氮 (BUN)增至 8 6mmol/L以上 ,血乳酸 (BL)增至9 8mmol/L以上 ,自觉很累 ,肌肉酸痛。吸用高压氧后 ,各项指标的改善与高压空气组和常压空气组相比更加明显 (P <0 0 1 ) ,疲劳感和肌肉酸痛基本消失。结论 :高压氧对运动员急性疲劳的恢复过程有明显促进作用。BUN和BL与疲劳感存在明显相关
Objective: To investigate the effect of hyperbaric oxygen on acute fatigue recovery of long-distance runners. Methods: A total of 18 healthy male long-distance runners were randomly divided into hyperbaric oxygen group, high pressure air group and normal pressure air group. Before long-distance running, immediately after the end of long-distance running, the heart rate, blood urea nitrogen, blood lactic acid and subjective fatigue were recorded after hyperbaric oxygen recovery and later recovery. Results: The heart rate of all the subjects increased to more than 1 75 beats / min after long-distance running, the blood urea nitrogen (BUN) increased to above 8 6 mmol / L and the blood lactate (BL) increased to above 9 8 mmol / L, ,Muscle ache. After inhalation of hyperbaric oxygen, the improvement of each index was more obvious than that of the high-pressure air group and the normal-pressure air group (P <0.01), and the fatigue and muscle soreness disappeared. Conclusion: Hyperbaric oxygen can significantly improve the recovery process of athletes’ acute fatigue. BUN and BL were significantly associated with fatigue
