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
Ok, you put in your numbers for the walking equation. That gives you mililiters of oxygen per kilogram of body weight per minute. Multiply that number by the body weight in kilograms. Divide that number by 1000. That will give you the total liters of oxygen consumed per minute. Then multiply by 5. This is the calories per minute burned (1 liter of oxygen is equal to 5 kcal burned per minute and 1 kcal is the unit that is called a calorie in layman’s terminology.) Then you multiply that by the minutes walking to get your total calories burned.
In your second question you gave me numbers of 10 min., 5 grade, and 100m/min (which isn’t running, it is walking less than 4 miles per hour).
Using the walking equation. I will assume a weight of 130 lb. or 58 kg.
.1 x 100m/min = 10
1.8 x 100m/min x .05(5% grade = .05) = 9
10 + 9 + 3.5 = 22.5 ml of oxygem per kg per min.
22.5 x 58 kg = 1305 mililiters of oxygen consumed per minute
1305 ml/1000 ml = 1.305 liters of Oxygen consumed per minute
1.305 x 5 (calories per liter of oxygen consumed) = 6.525 calories/min.
10 min. x 6.525 = 65.25 calories
65.25 total calories burned in 10 min. at this speed and grade.
It doesn’t matter the age or gender. For a person to move that body weight at that speed, up that grade for 10 minutes it will take approximately 60 calories. This is an approimation. This could actually be a little more or a little less depending on the person, depending on if they were swinging their arms excessively or very little, depending on the temperature, etc. It is just an estimate. Something to base how long your client would want to walk at this speed and grade to burn a certain number of calories in that workout. So, if you wanted your 130 lb. client to burn 300 calories in a single walk, thwy would need to walk for 50 minutes at 100m/min on a 5% grade to burn approximately 300 calories.
I teach this kind of material to students wanting to be trainers and trainers who need a little help with understanding the equations. But there are calorie calculators online that do this in a blink. Some of the calculators ask for age and height, but it isn’t really important in most of these calculators. Some might use a different equation, but the total calories are going to be very close. I created my own spreadsheets for this type of equation years ago I only teach the equations to demonstrate to students what goes into the making of a online calculator.
I am kind of doing this fast so it doesn’t take me all day, so I didn’t check my math. But I am fairly certain it is close since the answer sounds pretty average.
