I know several metabolic equations for estimating VO2 (and therefore calories burned) for steady state exercise, but how is VO2 and caloric expenditure estimated through exercises like power lifting and explosive exercise, like burpees?

This being said, what are the METs (metabolic equivalents) for such exercises? All METs I have seen are for physical activity, not for specific exercises.

I would like to know the caloric value of different exercises to estimate whether or not one is over-training.

My current formal education is heavily focused on health vs performance.

There are a few MET charts around that list powerlifting as a general category, but not for individual lifts. For Burpess and similar, I don't think they've ever broken them down individually, I've always just used the figures for various intensities of calisthenics. – JohnP Jan 9 '14 at 19:18

The following formula should allow you to convert between the 3:

MET = vVO2Max = VO2Max / 3.5 = kCalBurnt / (bodyMassKg * timePerformingHours)

VO2 = (currentHeartRate / MaxHeartRate) * VO2Max

where: MaxHeartRate = 210 - (0.8 * ageYears)

Kcal/Min ~= 5 * massKg * VO2 / 1000

Note: The 5 calories / min constant, assumes just carbohydrates are being converted, over a short period. If the exercise is sustained aerobically for a period this value drops to 4.86 to reflect a mix of fats and carbohydrates are being converted into energy.

A number of sites have MET estimates for specific activities eg.

So just use the formula above to estimate the calories spent performing a particular exercise eg. If you spend 6 mins on an Elliptical trainer (moderate effort), which has been assigned a MET score of 5.0, and you weigh 80Kg, you'dend up with:

KCalBurnt = MET * bodyMassKg * timePerformingHours
          = 5.0 * 80 * 0.1 
          = 40 KCal

The ACMS equations may also be of interest:

Arm Ergometry VO2 = (3 * workRateWatts) / bodyMassKg + 3.5

Leg Ergometry: VO2 = (1.8 * workRateWatts) / bodyMassKg + 7

Stepping: VO2 = (0.2 * (steps in a Min)) + 1.33 * (1.8 * stepHeightMeters * (stepsInAMin)) + 3.5

Walking: VO2 = (0.1 * metersWalkedInAMin) + (1.8 * metersWalkedInAMin) * (fractionalGrade) + 3.5

Running: VO2 = (0.2 * metersRunInAMin) + (0.9 * metersRunInAMin) * (fractionalGrade) + 3.5

Not what I'm looking for, but thanks. – Ellocomotive Feb 26 '15 at 20:15
Issue is the anaerobic phase of any exercise lasts no more than the 40 secs, essentially the time it takes your body to consume ATP already present in your muscle tissue. From that point on Oxygen is required to release the energy stored in the sugars and fats in your body, via the Citric acid cycle. – arober11 Apr 1 '15 at 13:07
Also potentially of interest an article that indicates the average body has approximately 8 sec worth of ATP available at any point: RULES OF THE AMATEUR UNPRO CYCLIST, also that the body can for a limited period, inneficiently convet glucose to ATP via anaerobic respiration. This anaerobic conversion is 1/9 as efficient at releasing energy from glucose as aerobic respiration and results in lactic acid. – arober11 Apr 3 '15 at 0:16
Finally either this article on Energy Pathways or chapter 3 of [Nutrition for Health, Fitness, & Sport, 7/e](…) may congain what you want. – arober11 Apr 3 '15 at 1:02
