Comparing the force- and excursion- frequency relationships in human skeletal muscle

Muscle Nerve. 2008 Dec;38(6):1627-9. doi: 10.1002/mus.21161.

Abstract

We examined the influence of varying stimulation frequency on muscle output during isometric and dynamic contractions. Our findings demonstrate that the predictability of the force- and excursion-frequency relationships is extremely strong across stimulation intensities. There were no differences in the frequency which elicited 50% of peak or peak muscle output. We conclude that the impact of varying stimulation frequency is consistent between isometric and dynamic contractions.
