WebJun 1, 2024 · Motor unit firing rates increased and new motor units were recruited between the beginning (in red) and the end (in green) of the initial phase, as evidenced by the upward shift in the motor unit firing rate vs. MUAP amplitude relation and by the presence of higher-amplitude MUAPs at the end of the initial phase. WebNov 25, 1997 · In motor neurons, for example, the strength at which an innervated muscle is flexed depends solely on the “firing rate,” the average number of APs per unit time (a “rate code”). At the other end of the spectrum lie complex temporal codes based on the precise timing of single APs.

WebMotor units detected from the TA muscle were found to have a continual decrease in their mean firing rates in 36 of 44 trials performed during isometric ankle dorsiflexion at force values ranging from 30 to 80% of maximal effort and a duration of 8-15 s. WebOct 3, 2024 · Over most of the operating range of a muscle, the nervous system controls muscle force by varying both motor unit recruitment and rate coding. Except at relatively low forces, however, the control of muscle force depends primarily on rate coding, especially during fast contractions. facebook boeing rc-135
