No I am not aware of any scientific studies that have been conducted. Mr. Anslow has reported on a small study conducted maybe in Canada by the ITF-V. I am not sure how scientific it was, nor would I feel very comfortable with a study conducted by an involved party, due to bias related issues.
In that study, I think there were minor increases in some areas, no change in others & some loss of power in other areas. I also do not think there was a large sample size & other controls that scientific research requires in order to pass the snuff test.

Bottom line is that it FEELS more powerful to me. But lime I said, it is for performing basic, fundamentals in isolation. Think power test or breaking.
