Are We Systematically Short Changing Ourselves by 50% for Calories Burned in Strength Training Exercises?

Study Says Anaerobic Exercises Burn Two Times More Energy Than Previously Thought

From SuppVersity:  
If we go by the data from the ... study, push-ups and pull-ups burn 50% and 62% more energy than we previously thought they would [respectively].  Against that background it's no wonder that participants ... [went] from 16% to 8% body fat. ... 
[T]he methods we use to calculate the [energy expenditure] of anaerobic activities significantly ... underestimat[e] of the energetic costs of anaerobic activity. ...

"Traditional" in this context means using calorimetry to measure oxygen uptake continuously throughout the trial. "Oxygen uptake" and "anaerobic activity" - when you come to think about it ... [don't] really go together.  The former is ... specifically high, when you perform "aerobic," not anaerobic activities. ... [The alternate alternate "improved" method used in this study measure oxygen uptake during the rest periods subsequent to exercise.]

In spite of the fact that it is questionable, whether the alternative the scientists used, i.e. measuring the oxygen uptake during recovery, instead of during activity, is actually "accurate", it goes without saying that the real world health benefits and weight loss results people achieve, when they lift heavy weights or perform high intensity interval training would support the notion that the de facto energy expenditure could have been significantly underestimated.
