    Does anyone know how to calculate your cardiac output? Of course, without being in a labratory, it's going to be an estimate at best.

    (I'm searching for things on google, but you never know what you are going to get from the internet).

    "Stroke Volume" or "VO2Max" ?

    I think my Physiology prof. said VO2 max was really hard to calculate. Do you know a way?

    I need to know stroke volume for my test next week….
    Stroke Volume would be "End Diastolic Volume – End Systolic Volume", but I don't know how to calculate EDV and ESV.

    Cardiac Output, or the amount of blood that gets pushed through your body in one minute, is what I am looking for. Average male at rest is 5L. It can get up to 30L/min for elite athletes.

    I think in order to calculate one of the steps for CO, you need to know SV.

    Ryan,
    I do not. But Google "joe friel" and "vo2 max" to get some ideas. Typically it is quantitativly found in a lab, monitoring respiration gases as levels of exertion go to max. For a cyclist it's associated heart rate is a percentage of HR max., but that doesn't lead to "52 L/min.".

    Good Luck.

    To be most accurate you need to run on a treadmill in a lab with all the necessary equipment etc.
    There is a rough estimate way of getting VO2 Max and that is running 1.5 miles and using time and pluggin it in a formula.

    this is a general guide based on running times, but is derived from lots of research and stats:
