WebTranscribed image text: When a muscle lifts a load, it does so according to the "fundamental equation of muscle contraction, " also known as Hill's equation, (L + m) (V + n) = k, where L is the load that the muscle is lifting, V is the velocity of contraction of the muscle, and m, n, and k are constants. Use implicit differentiation to find dV/dL. Webin a fixed end contraction and L' therefore is zero. Accord-ing to Hill's definition, the CC must then instantly produce a force equal to the active state level existing at that time. Hill argued tha ift soo, n afte ar stimulus , a quick stretch were applied to a muscle in order to extend the SEC to the length
