Question

Quizplus · Accepted Answer

The load on the fiber, or the weight or resistance being lifted, affects the velocity and duration of muscle contraction. Heavier loads require more force and lead to slower and shorter contractions, while lighter loads can be lifted quickly and sustain contraction for longer periods of time. The other factors listed may impact muscle strength or endurance but do not directly affect velocity and duration of contraction.
