Abstract
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 capillary 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). The regression equation for predicting venous hct. from finger tip capillary blood after exercise was: Hct v = 0.87 Hct c+6.44 withr = 0.95 (P<0.05). The results indicate that the finger tip capillary microhematocrit method is a valid indicator of venous blood hct. following exercise.
