I'll leave the Lieberman reference alone.... 😉 That's a huge can of worms. Regardless, I really don't think instrumented treadmills are necessary to get to the answer and in fact, would be more challenging to get a satisfactory answer than some simpler alternatives. As I say, I know quite a lot of elite players and can deduct broad principles from that data I have. Alternatively, some simple, well conducted on-ice testing could get to the answer as well. As I alluded to earlier in the thread, we were going to do some of it with my son after making the changes, but he's absolutely convinced in the set up he wants now and any amount of testing I do won't make a bit of difference. That's another thing about hockey, the mental piece is huge and if you make a change that the athlete perceives reduces performance, it will affect confidence to the point that it will likely reduce performance regardless. A self-fulfilling prophecy or a negative placebo effect if you will.
Anyway, thanks for the feedback. We've gotten far enough off of the topic, we probably should leave it at this point.
