WebJun 1, 2006 · Because the excess heat of shortening must be zero when there is no shortening (during an isometric contraction), c must equal b P 0, where P 0 is the force generated by an isometric contraction. Incorporating this fact and rearranging the equations yields the famous Hill equation, presented as Eqs. 1 and 2 in his paper: (6) WebIntroduction. The slower a skeletal muscle shortens the greater the force it can generate during contraction and vice versa.This force-velocity (F-V) relationship is a fundamental principle of skeletal muscle physiology that was derived based on Hill’s ground-breaking studies in isolated frog muscles and originally used to develop theories of the …
