However, the one thing I find VERY odd is this conclusion:

"In contrast, the SLOW group did not experience significant changes in muscle fibre type or muscle torque."

Especially since we have the fact that ~5-6s negatives helped me gain enough strength to do OAC after ~6 week cycle. Granted, I'm sure a lot of it was neurological, but my muscles did grow significantly as well.

It does make sense that the highest threshold motor units are recruited when the joint angle is opening fast because they provide the most force and thus can stop the joint from opening too fast which would cause trauma to said joint. This was said in the first post (of the two above mine), and I would speculate that's because the GTO's act somewhat differently under eccentric vs. concentric contractions.... which is the difference of lengthening the muscle allows feedback to increase tension in the muscle vs. possibly autogenic inhibition. Or something like that. -_-
I wonder whether weighted OAC negatives in the 1 sec range would be useful versus staying with the 5-6 sec range.

I wish I had more opportunity to experiment. Unfortunately, I don't have much time to strength train now that OCS is approaching and that my conditioning is sorely lacking.
