Kettlebell training burns 20 kcal a minute
If you combine interval and kettlebell training you can burn 20 kcal per minute. Sports scientists John Porcari and Chad Schnettler, both working at the University of Wisconsin, managed to devise a 20-minute training session that achieved this: their test subjects burned an amazing 400 kcal.
The researchers calculated the x number of reps for each test subject beforehand. They did this by getting the subjects to do as many snatches as they could in one minute and then dividing that by 4. So if a subject did 20 snatches, they had to do 5 during the training session.
The subjects could choose out of kettlebells weighing 12, 16 or 20 kg.
This kind of training is heavy going on the heart muscle. There’s another study on the effect of kettlebell training that shows this. [J Strength Cond Res. 2010 Apr; 24(4): 1034-6.]
By measuring the subjects' oxygen use, the researchers calculated that they burned 13.6 kcal per minute during the workout.
"We also measured the blood lactate, so anaerobically they were burning another 6.6 calories per minute", Porcari explains. "So they were burning at least 20.2 calories per minute, which is off the charts. That's equivalent to running a 6-minute mile pace. The only other thing I could find that burns that many calories is crosscountry skiing up hill at a fast pace."
