Why I use kettlebell swings so much with my clients and I?
A couple of sports scientists from the University of Wisconsin wanted to see how many calories one-arm kettlebell snatches would burn, so they devised a formula and protocol.
here is what they found. "So they were burning at least 20.2 calories per minute, which is off the charts," exclaimed one of the researchers. "That's equivalent to running at a 6-minute mile pace. The only other thing I could find that burns that many calories is cross country skiing uphill at a fast pace."
Based on their use of oxygen, the trainees burned 13.6 calories
their blood lactate levels and found they were burning an additional 6.6 calories per minute.
kettlebell swings maximal and explosive strength.
The aim of this study was to establish the effect that kettlebell swing (KB) training had on measures of maximum (half squat-HS-1 repetition maximum [1RM]) and explosive (vertical jump height-VJH) strength. To put these effects into context, they were compared with the effects of jump squat power training.
here is what they found
strength gains found were no significant difference between the effect of kettlebell swings and verticle jump height training
The results of this study clearly demonstrate that 6 weeks of biweekly KB training provides a stimulus that is sufficient to increase both maximum and explosive strength offering a useful alternative to strength and conditioning professionals seeking variety for their athletes.
Basically its a low impact high intensity excercise that can melt body fat while increase maximum explosive strength
