Abstract
Blood volume (CO method), Hb (Palmer), erythrocyte number, and erythrocyte osmotic resistance (Hasting''s method), were determined on the blood of dogs physically trained by treadmill running or swimming in water at 30[degree]C. During the 1st week of exercise, the blood volume and red corpuscle count were markedly decreased (15-20%), but with continued exercise they returned to the pre-exercise normal level and subsequently exceeded normal. Alkali reserve of the blood was increased in both running and swimming dogs after a period of physical training. Erythrocyte osmotic resistance increased in the swimmers, but decreased in 1 running dog. Body temp. (rectal) was decreased by about 2[degree]C after swimming and increased about 1[degree]C after running exercise. It is suggested that body temp. may be a factor in osmotic resistance changes of erythrocytes.This publication has 1 reference indexed in Scilit:
