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. Muscle Nerve, 2008

## Abstract In previous work we developed and validated a mathematical model that predicted force output from skeletal muscles subjected to six‐pulse stimulation trains under isometric condition. The current study investigated the model's ability to predict force responses to longer stimulation tra

Variable-frequency trains that exploit the catchlike property of skeletal muscle can augment force production in fatigued skeletal muscle. The present study is the first to examine the effect of such trains during recovery. The quadriceps femoris muscles of 12 healthy individuals were fatigued using
