Abstract
The effects of body movement on left ventricular performance during long- distance running in humans were studied in a simple tubular model of the aorta and lower limb arteries. In this model, interaction between pressure waves generated by the heart with waves caused by upward body movement created a type of 'beating' phenomenon similar to that previously seen in humans when heart and step rates were similar. If heart and step rates can be entrained and locked together, the resultant reduction of arterial pulse pressure can produce the substantial benefit through reduction in myocardial oxygen demands, increase in myocardial blood supply, and increase in cardiac output. Relevance of this phenomenon in humans has not yet been examined.
