    bpm during cardio

    Everyone talks about getting there bpm to 70-75% of their max in order to burn fat efficiently. Anything higher than that is considered the cardio zone. Here's my question...

    What exactly is happening to your heart and body when it's in the "fat burning zone" and the "cardio zone"? What's the difference between the two in regards to how your body uses energy? Thanks guys.

    fat burning zone is less energy out put for a longer period of time, your using up glycogen storage and then moving on to fat, with cardio past 30-40 min your body turns to fat/muscle on your body since there is more energy here, think glucose is like 4 atp's and fat is 6 or something i don't know it has to do with the kerb cycle you can look that up if your that interested
    peace dude

    ok here we go in a nut shell bro:

    Maximal heart rate is used to determine excercise training intensity in cardiovascular excercise. Max heart rate is the max attainable heart rate at the point of exaustion from all out exertion. Increses heart rate is directly related to increase in how much oxygen is consumed during excercises.


    -- max heart rate is based on one age , the equation most often used is
    maxHR=220-age


    --there is a standard deviation of 10-12 bpm. This means that the appox. 67% of the population will have a max heart rate of 220 minus age plus or minus 10-12 bpm.

    --Heart rate training zones are estimates based upon the OBLA( onset of blood lactate) Prior to this onset, the majority of the energy being utilized is generated through aerobic sources. As the duration of the excercises increases, there is an increase in fat utilazation as a energy source. Heart rates prior to OBLA are best for endurance and aerobic system training.

    --The goal in utilizing the 'theoritical fat utilization' zone is to find a point wher ewe train the body to use fats as a fuel source opposed to carbs(glocose and glycogen) or amino acids( protein found in the blood system)

    Hope this helps
