One of the major things that it seems that YMAA does is evaluate the scientific evidence for various aspects of the traditional Oriental healing and martial arts. I found an interesting apparently clinical study earlier on the Kung Fu Yau-Man palm strike. While it might seem like a very obvious thing, there are several citations that suggest that this study did prove a connection between training and what S. M. Machado, et al. described as the "power of the impact." Richard P. Bolander, et al. also wrote about the way that optimal force transfer occurs when the body is able to take certain postures and enter a state of perfect alignment.
I was wondering what other people thought of this study.

Speaking of studies, I believe it was Dvivid who had earlier said that practitioners don't need to wait around for scientific studies to tell them what they already know. I found an interesting story from 1988 about someone who was using some form of Chi Kung to stave off some of the effects of Cystic Fibrosis. Sadly I couldn't find if this Craig Reid individual was still with us, but the story itself is rather inspiring.
