We all have our unique relationship between cardiac
stroke volume and pulse
pressure (with age, pulse pressure:stroke volume ratio tends to decrease), but in young healthy males it can be approx. 1.7. Which means, if your pulse pressure is 80 mmHg, stroke volume may be 136 ml.
When I'm exercising at peak intensity, my blood pressure is approx. 200/70 mmHg. Which means, my heart is pumping lots of blood for each heart beat.
It's really that simple. Your heart beats with high force.
