The purpose of this study was to determine if finger tip capillary blood hematocrit is a valid estimate of anticubital venous blood hematocrit at rest and after submaximal exercise. Simultaneous samples of finger tip cpaillary and venous blood were drawn from thirty-one subjects (15 males, 16 females) before and after a 15 min submaximal exercise on a bicycle ergometer. Venous and capillary blood hcts. were 42.0% +/- 3.9 and 42.0% +/- 3.5 respectively before exercise and 43.3% +/- 3.5 and 42% +/- 3.8 after exercise (X +/- s). The regression equation for predicting venous hct. from finger tip capillary blood after exercise was: Hctv = 0.87 Hctc + 6.44 with r = 0.95 (P less than 0.05). The results indicate that the finger tip capillary microhematocrit method is a valid indicator of venous blood hct. following exercise.
本研究的目的是确定指尖毛细血管血细胞比容是否是静息及次最大运动后肘前静脉血血细胞比容的有效估计值。在31名受试者（15名男性，16名女性）于自行车测力计上进行15分钟次最大运动前后，同时采集指尖毛细血管血和静脉血样本。运动前静脉血和毛细血管血血细胞比容分别为42.0%±3.9和42.0%±3.5，运动后分别为43.3%±3.5和42%±3.8（X±s）。运动后根据指尖毛细血管血预测静脉血细胞比容的回归方程为：Hctv = 0.87 Hctc + 6.44，r = 0.95（P<0.05）。结果表明，指尖毛细血管微量血细胞比容法是运动后静脉血血细胞比容的有效指标。
