    heart rate while exercising = calories burnt?

    While performing aerobic exercise does ones heart rate equal how many calories they are expending?

    For example, if one is jogging on a treadmill @ 140 bpm, will they be burning the same amount of calories as one who is on the stepper machine @ 140bpm as well?

    Its an indicator, but not the only factor involved.
    Vin Diesel has a fever.. and the only prescription is more cowbell.

    time spend doing the exercise. the body adapts and becomes efficient.

    a person just starting out on a stairmaster (vs someone who has used it for weeks) will undoubtedly burn more calories due to inefficiency of the nervous system and that movement. when the pattern is established, the nervous system will be more efficient and fire off just the required amount of muscle to do the movement, so in a sense the exercise gets easier. so take a person just starting on stairmaster, and a person who has done it for a few weeks, at the same level, chances are the person just starting will burn more due to sloppiness. (provided they are the same fitness levels)

    I'm not sure exactly how accurate that is.

    Neural efficiency aside, it still takes x calories to do x amount of work.

    Biomechanical efficiency would be much more important in determining calories expended than neuromuscular efficiency-- and there's not much short of radical surgery that can change that.

    correct me if im wrong, but doesnt your weight play a huge part in determining the amount of calories one burns?

    Muscle tissue does. The rest is pretty much inactive goop in comparison.

    ok here's a question: lets say two people have the same amount of muscle, but one also has significantly higher amounts of fat. Wouldn't the overfat individual's muscles have to work harder to move and work and exercise? So wouldn't he expend more energy?

    That depends on what exercise is being done, but for the most part, yes.

    If I strapped on a 75 lb weight vest and started running, I'd use a lot more calories than if I ran naked (which I do on occasion).

    Its the same idea.

    so to answer the question...

    no, heart rate doesnt dictate a set amount of calories burned due to different amounts of work performed with different muscle groups.

    chances are a person doing 140 bpm on an arm ergometer is burning way less calorie wise than a person on a versaclimber @ 140bpm
