Da da daaaaa, clearly you don't know the force-velocity relationship very well and this lit review is appropriate.
Muscle force within muscle INCREASES with increased eccentric lengthening velocity, but there is more for you to look into there.
I would also suggest that in terms of neurophysiology you try to encompass recruitment patterns of the concentric/isometric/eccentric contractions rather than just describing the F-V relationship. Just sticking to the F-V relationship is more about viscoelastic properties of muscle (and structural issues), rather than something that is truly neurophysiology.
For a pure neurophys topic, why don't you do Hennemann's size principle with application to resistance training.
