Well you do have a point, if athletes can do this kind of stuff (my claim) then why would professional athletes who attend these seminars not be able to understand/do it.
It's a good point.
And the point I'm always asking about in return, which would be, if these "IP" guys have such amazing power why aren't they out there winning gold metals at every Olympic event.
I think I hit on this earlier, and it answers both of these questions. All practices/sports have specifics, that must be learned in order to do the practice/sport. For example, a world class Tennis player is likely not going to be a great football player, unless they trained in that sport. So even though both the football player and the tennis player are athletes, the football player might have a crummy backhand, and marvel at the tennis player, and the tennis player might not be able to catch anything at all and be amazed at the football player.
So then we get down to the specifics of the demonstrations of "IP". Those are also specific skills that take some practice to get the hang of.
But there is an interesting question here, why don't the "IP" guys dominate in the fields where the should understand the specifics of the sport/practice. For example why aren't "IP" guys winning MMA matches?
Again, we might get into specifics of the practice. But if we look at a guy like Ark, he was a serious Kickboxer, I'm not sure if he was a professional kickboxer or not, but I know he was very serious. If "IP" offers a great physical advantage to it's practitioners, and it's practitioners know the specifics of a practice/sport, then why wouldn't that "IP" expert become a world champion at the sport he competes in?
So I would say specifics of a practice are the difference, they might be athletes all, but the different disciplines make it difficult to cross lines. However if an "IP" expert does have a serious physical advantage, and does train in a sport, he should be the best, or at least at the top of his field in that sport. Correct?
IP is like having really good cardio. It can be an element of a great athlete, but it isn't the only thing. I think any IP proponent will tell you there are differences between IP and fighting, and that like good cardio it can make you a better fighter. This is kind of like how a gymnast or dancer, could, if so inclined, pick up judo fairly quickly due to a developed sense of balance and cardio.
Given that the pool of people with this stuff was pretty small, and that it was rather secretive, asian arts still aren't all that open about giving away this stuff. Its counter intuitive, but its a lingering cultural artifact. I figure if anyone, a westerner with exposure will do it, eventually.
Now as for dominating MMA (and other sports) there are a number of reasons, not necesscarily related to IS/IP. You can't just walk into the UFC, unless Dana White gives you a chance. You would have to work your way up of course, but it helps if your particular gym has connections to a particular promoter. I think what you are more likely to see are various guys doing very well on the amateur level. I know the aunkai guys regularly enter K2 matches.
There is another issue to. Once your body starts getting wired this way, if you step into a dojo, you will get flack for not moving "the right way". I know some amateur kick boxers who have this issue, and I've experienced it with nanadan/hachidans in kendo and iaido (and burned some bridges as a result).
Now I have seen Ark do some pretty interesting things. I have video of his first trap session where he sat in horse stance and hit 80% of the clay pigeons. A shotgun shooting stance looks nothing like that. Likewise he has shot pistol and rifle for the first time and done exceedingly well. I also have video of him hitting over 300 yards with a 3 wood shot after shot, despite not picking up a club in 10 years. He did remark after that he should be giving Golf Seminars rather than IS ones.
In this case, Ark has a really good base to develop off of, in that he can integrate the golf club or firearm into his body and thus due to his stability, is less effected by recoil, has less movement in the firearm and a better sight picture. In golf, he can better transfer his weight and effort into the ball. Either one would take considerable effort to get to an elite level, but perhaps less than someone starting from nothing.
