grip with three fingers - why?
Ok, I was reading Competitive Judo a few days ago at a local B&N, and there is a passage that caught my attention. The book suggests to grip with the three lower fingers only. The index and thumb are kept in place (or have reduce participation in gripping compared to the lower three I would assume.)
The rationale of the book is that by doing so, you reduce fatigue - using the index and thumb involves muscles in the forearms whereas the lower three involve muscles in the wrist. By minimizing the involvement of the forearms, you reduce lactic acid buildup (according to the book), thus reducing or postponing fatigue during gripping.
It seems reasonable to me to reduce lactic acid build-up, but other factors may be at play (strenght of wrist muscles, duration of grip, etc.) I've seen a couple of posts on this at different forums, BUT there has not been a conclusive discussion of this as far as the search function shows.
Any annectodal or scientific evidence pro or con this assertion????
BTW, I put this thread at this forum because it doesn't seem to fit in either the grappling or striking forums, nor in the health/fitness related forums. Please let me know if this should have been better fit in a different forum.
