Q: what is the sole effect of muscle hyper/hypo-trophy (or force change) on the mechanical power generated across the joint (i.e. when the shortening of the muscle is kept constant)?

A: the simple answer is that power increases with the force change to the power of 1.5 (power is force times velocity, thus is force increases, also speed increases, and the product of the two is potentiated beyond the simple force change). I wrote a mathematical model that tells us that the gain in power depends also on whether the movement is horizontal or vertical.
