I want to calculate burn calorie walking, running cycling, stepping and I am using your documents of ACSM Metabolic Equations (HPRED 1410, Dr Bailey, Appendix D, Guidelines) as follows;
VO2 (mL . kg-1 . min-1) = (0.1 . S) + (1.8 . S . G) + 3.5 mL. kg-1.min-1
VO2 (mL . kg-1 . min-1) = (0.2 . S) + (0.9 . S . G) + 3.5 mL. kg-1.min-1
VO2 (mL . kg-1 . min-1) = 1.8(work rate) / (BM) + 3.5 mL. kg-1.min-1+ 3.5 mL. kg-1.min-1
VO2 (mL . kg-1 . min-1) = 3(work rate) / (BM) + 3.5 mL. kg-1.min-1
VO2 (mL . kg-1 . min-1) = (0.2 . f) + (1.33 . 1.8 . H . f) + 3.5 mL. kg-1.min-1
but there is no factor and consideration of gender, age!
Is it right document for calculate the calorie burned or should I use different document.
Please help me
There is no gender or age component for those equations because age and gender were not part of the data that went into developing the equations. Age and gender must have had little effect on the calories burned using those equations. Equations like those are developed by using a large amount of actual measured findings over a broad range of test subjects. These equations have a margin of error as well, but they save us from having to do all the blood testing, ventilation measurements, calorimeter measurements,etc. that cost a lot of money. We just estimate the calories with the equation. The real burn would be different, but not significant enough to spend the money to find out how different.
The amount of energy needed to move a certain amount of mass during those activities is fairly consistent whether a man or woman, young or old.
I would speculate that it is independent of things like muscle mass, heart size/output, or lung efficiency as well. Logically, more muscle would simply use less energy in each muscle unit but in more muscle units. A large volume of cardiac output would simple be quicker to deliver oxygen and substrates, but not reduce how much energy was need to get the muscle contracting. And the rate at which oxygen is moved into the system and CO2 out will also have little effect on the energy need to move X kilograms over some distance Y.
Age and gender do make a difference in things like % body fat, VO2 max (which has little to do with actual energy needed to do aerobic work, just how much oxygen you can put into that work), etc.
If you want to discuss this more, I would be happy to try and answer some questions via email. Contact me through my profile if you want.
