Blood volume and exercise in dogs.

I H Sarelius

    The New Zealand Medical Journal
    |October 13, 1976
    PubMed
    Summary

    Exercise increases plasma volume and haematocrit in dogs. These physiological changes, particularly a 14% rise in haematocrit, persist for 10 minutes post-exercise, indicating significant cardiovascular adaptation.

    Area of Science:

    • Veterinary Physiology
    • Exercise Science
    • Cardiovascular Physiology

    Background:

    • Understanding physiological responses to exercise is crucial for animal health and performance.
    • Plasma volume and haematocrit are key indicators of hydration and oxygen-carrying capacity.

    Purpose of the Study:

    • To investigate the effects of exercise on plasma volume and haematocrit ratio in canine subjects.
    • To quantify the changes in these hematological parameters during and after physical exertion.

    Main Methods:

    • Canine subjects were subjected to an exercise protocol.
    • Plasma volume and haematocrit levels were measured before, during, and after exercise.
    • The duration of post-exercise physiological changes was recorded.

    Main Results:

    • Plasma volume demonstrated an increase following exercise.
    • The elevated plasma volume persisted for 10 minutes after exercise cessation.
    • A significant 14% increase in the haematocrit ratio was observed post-exercise.

    Conclusions:

    • Exercise induces substantial and sustained alterations in plasma volume and haematocrit in dogs.
    • These findings highlight the dynamic cardiovascular adjustments dogs undergo during and after physical activity.
