cockeral stands on one leg.
all performed with issuing power (fajin): without concentric contraction and only eccentric contraction taking place in the movements/ postures.
If it's real, then the least you can do is show me how you do it. And a description of what differes to the 'regular way' of performance would be a help.
Can you also explain why you think when a tai chi practitioner was scientifically measured why concentric contraction was detected (which I think is fair to assume would be typical) - and then please explain why exactly it would not be detected in your performance. Let's say for argument sake it's a typical Yang style kind of form. Can we do that ?
You must have some answers for that kind of enquiry, otherwise, for me at least, this goes nowhere productive. It would be nice to see it - but a reasonable explanation would make a nice start.

Ron Panunto wrote:Well, my thought is that standing postures are the essence of developing internal strength, and eccentric muscle contraction can be considered as a "braking" type movement, that is when we are sitting the horse, our thighs are parallel to the ground and our quadriceps are contracted eccentrically as a "brake" to keep us from falling to the ground. The same in zhang zhuan where we are standing as if sitting on a bar stool, and when tree hugging is added, the anterior deltoids are eccentrically contracted as a brake to keep our arms from falling down. My point is that if my analysis is true, then eccentric muscular contraction does indeed play an important part in the internal arts.
