In fact, the extra strength is DUE to the nature of the contraction.
When you do a negative, the little paddles (myosin heads) hang on longer and stretch till they pop loose, then quickly grab lower, etc. Almost like the differnce between you clilmbing a ladder and someone pulling you backwards down a ladder while your trying to climb up. You′d grip, stetch, slip, and re-grab, etc.
One of the other reasons it′s different is the neural system has trouble coordinating smooth action in a negative, so there is uneven lengthening of the sarcomeres, this puts lateral tension on them and they pop from the side forces also.

Some points to help you understand...
* A fiber does display more tension in a negative, because of the mysosins hanging on
* The sarcomeres (each section of contractille element containing the actin-mysosin) lengthen in an uncoordinated fashion so experience lateral stresses.
* A concentric (positive movement) finds them moving orderly and more together.
* Sarcomeres are more apt to pop during a negative, this could also be one of the triggers for growth and repair.

I′m starting to tell some big detail differences in my muscles now. Hopefully, by the time I get down to around 155, I′ll be pretty ripped. Only time will tell.
