    Centripedal forces and the calf muscle pump

    You will be aware of the foot pump and the calf muscle pump and you might well have read texts which describe their function . In every text I have ever read the calf pump in particular is described as helping to move blood towards the heart against gravity . However what about the centripedal forces and centrifugal effect generated in the legs and vasculature during walking and running . I have never ,in years of looking ,found a paper on venous return which takes these forces into account when ,for example ,discussing venous reflux .

    Surely these forces are increasing relevant as you move from slow walking to brisk walking to jogging then running then sprinting .

    It is worth noting that in individuals with previous heart failure and thus reduce cardiac capacity , poor venous return may reduce preloading (Starling mechanism ) and thus cardiac output .

    What do you think . Have the vascular people missed a trick ?
