目的：观察吸氧对大强度运动后红细胞形态、血液流变特性变化的影响。方法：７名男子采用功率自行车进行递增负荷运动，并在安静时，运动后３、１５、３０分钟测定全血粘度（ＢＶ）、血浆粘度（ＰＶ）、血细胞集聚指数（ＲＣＡ）、红细胞变形指数（ＴＫ）、红细胞压积（Ｈｃｔ）及红细胞形态等指标。同时比较各指标在恢复期吸氧与吸空气条件下的变化。结果：（１）在安静时吸氧与吸空气条件下，血流变各指标相比较无显著性差异；运动后３、１５、３０分钟，吸空气条件下血流变指标ＰＶ、ＲＣＡ、ＴＫ、Ｈｃｔ及第１５分钟心率（ＨＲ）明显高于吸氧条件。（２）运动后３、１５、３０分钟，吸空气条件下红细胞形态与吸氧相比较明显不同；吸氧条件下第３０分钟变形的红细胞已恢复到安静时形态。以上结果表明，运动后恢复期吸７０％Ｏ２，能够加快血流变各指标、红细胞形态的恢复，可能是运动后疲劳消除的重要方法之一。
Objective: To observe the effect of oxygen inhalation on the changes of erythrocyte morphology and blood rheology after intensive exercise. Methods: Seven men used power bicycles to carry out incremental load exercise, and at rest, the blood viscosity (BV), plasma viscosity (PV), hematocrit (RCA), erythrocyte deformability index (TK), hematocrit (Hct) and red blood cell morphology and other indicators. At the same time, the change of each index during the period of recovery oxygen and air suction were compared. Results: (1) There was no significant difference between the indexes of blood rheology under the conditions of oxygen inhalation and air suction at quiet time. The blood rheology indicators PV, RCA, TK , Hct and the 15th minute heart rate (HR) were significantly higher than the oxygen conditions. (2) At 3, 15, and 30 minutes after exercise, erythrocyte morphology was significantly different from that of oxygen absorption under air aspiration condition; the deformed erythrocytes in the 30th minute after oxygen inhalation had returned to the resting morphology. The above results show that 70% O2 recovery during exercise recovery can speed up the index of hemorrheology and the recovery of erythrocyte morphology, which may be one of the important ways to eliminate the fatigue after exercise.
