May inform CNS force-maximization strategies in animals; leaves open translation to human motor control or clinical stimulation.
Motor units exhibit marked hysteresis during frequency-varying stimulation, suggesting a central nervous system strategy to maximize force at any discharge rate.
Binder‐Macleod et al. (1989) studied this question. Stimulation with linearly varying frequency was evaluated on Force output and force-frequency relation (hysteresis). Stimulation with linearly varying frequency produced marked hysteresis in all motor units, with greater force produced when frequency was decreasing than when it was increasing.
