Muscle Power

In Brief Force-velocity, force-time, and force-length relations of muscle are typically evaluated with reductionist techniques in which force is measured while the variable of interest is manipulated. However, force produced during voluntary movement arises from complex interaction of these contractile characteristics. Nonetheless, neuromuscular performance for cyclical, work-producing movements can be predicted from the interaction of average muscle shortening velocity and movement frequency. Muscle shortening velocity and cycle frequency, which represents excitation state, interactively constrain muscular power across a wide range of conditions.
