PROBLEMS VIEWING SLIDES!
having problems viewing???
The studies within this presentation are severely flawed through lack of validity. Validity is paramount in the process of interpreting research. Reasons these studies are invalid:1) None of the exercise administrators are RKC or SF certified, therefore
more» the variables (exercises tested) will be flawed, skewing the results.2) Exercises done incorrectly will change muscle fiber recruitment dramatically.3) In one of the studies, one of the variables is the back squat. A back squat cannot be done with kettlebells, only a front squat can (which is substantially different in muscle recruitment). Yet instead of comparing the two squats, they try to compare a back squat to the swing. Apples to oranges I am afraid.4) You cannot metabolically compare interval training with steady state training with time as a variable resulting in caloric expenditure. (treadmill vs. Swing intervals) Once again apples to oranges.Another issue is that kettlebell training includes much more material than just the swing. I realize there is a lack of research on this art, but the presenter should be more responsible in titling his presentation. I do commend the presenter on bringing this issue of researching kettlebell training and attempting to quantify the results. Hopefully these attempts will improve future efforts and motivate others to do the right thing and get properly certified to teach such a specialty of the fitness world. There is no doubt in my mind that when we test the Windmill, Bent Press, Military press, Renegade Row, Turkish Get-up, Arm Bar, Farmers Walk, and the Pistol, just to name a few, we will see the true results of what kettlebells can do compared to the traditional plate loaded or dumbbell weight lifting techniques.Respectfully,Chris Newton - MS, CSCS, RKC II, MAT«less
Good informative. very informative and simple to comprehend
Just to clarify, the swings performed in our studies (Lake and Lauder) used a Hardstyle "hip hinge" swing.
Very good, but the 12 minute protocol used by Farrar et al. WAS NOT non-stop, but rest as necessary. The idea of this protocol is to exercise to a 'comfortable stop' for 12 minutes.
