Question

Explain why the shortening velocity became slower as the load became heavier in this experiment. how well did the results compare with your prediction?

Answer 1

The shortening velocity refers to the speed of the contraction from the muscle shortening while lifting a load. Maximal shortening velocity is only attained with a minimal load. With a light load, the shortening velocity is at its Maximal shortening velocity. When the weight is heavy, the speed in which the muscle lifts the weight decreases in speed at a slower velocity.
