ACE Article: Quantified 50% Additional Anaerobic Calorie Burn in VWC KB Workout

There have been two threads mentioning the ACE research on kettlebells but no thread has focused on some language I found extremely interesting in the article. First it bears mentioning that the article was heavily influenced by VWC; however, I cannot see that the article cites to the VWC book (the ACE link only gives us the first two pages so perhaps a cite comes later). For example, the article uses the cMVO2 test and it uses a 40 set 15:15 protocol to calculate results. Additionally the article mentions calories burned based on oxygen consumption and comes up with a figure (average of 272 calories in 40 set 15:15 workout) that is nearly exactly half cited in VWC in an 80 set 15:15 workout (see p.60 of VWC mentioning 542 calories).

With respect to calories burned, the article mentioned something very interesting that I had never seen quantified before, namely anaerobic calorie burn. Clearly, VWC and the article both reference calories burned through oxygen consumption—aerobic calorie burn or perhaps there is a more precise term. In my years of reading fitness books and articles, I have seen many sentences like this one on p.61 of VWC “Scientists have concluded that ‘by using explosive contractions and moderate exercise intensity, experienced recreational exercises can increase their energy expenditure during and after resistance exercise, and this could enhance weight-loss adaptions.’” Who knows what that means. Or, I’ve seen references to an “afterburn” or other such non-specific terms.

Well this ACE article says the following on the second page: “But we also measured the blood lactate, so anaerobically they were burning another 6.6 calories per minute.” This means in addition to the average 13.6 calories burned through oxygen consumption, there is nearly 50% more calories burned.

I wonder if this anaerobic calorie burn is the same as the afterburn or what the Scientists in the quote above were mentioning. Is this calculation something new? Perhaps someone with more scientific background like MC or Kenneth Jay can offer some further elaboration.

Here is the link to the study again:
