Slow motor units
Webb3 juni 2024 · Slow motor neurons produce <0.1 µN per spike, while fast motor neurons produce ~10 µN per spike, approximately equal to the fly’s weight. Recordings during spontaneous leg movements revealed a recruitment hierarchy: slow motor neurons typically fire first, followed by intermediate, then fast neurons (Figure 5).

Webb12 maj 2015 · During the first 3 reps, I might only be using small/slow motor units and muscle fibers. By the 6th rep, the smaller fibers have fatigued a little and can no longer produce enough force to move the weight, and I begin recruiting larger muscle fibers. Webb16 okt. 2024 · The primary mechanism at lower levels of muscle contraction strength is the addition of more motor units, but the firing rate of the initially recruited motor units also increases. When...
