WebbSlow motor units, for instance, provide the tension necessary for standing. Fast fatigue-resistant (FR) units, in turn, provide additional force required for activities such as walking and light running. Lastly, fast fatigable units are recruited for the most demanding activities. From: (Purves D, 2001). -After (Walmsley et al., 1978).

WebbLiterature examining the recruitment order of motor units during lengthening (eccentric) contractions was reviewed to determine if fast-twitch motor units can be active while lower threshold slow-twitch motor units are not active. Studies utilizing surface electromyogram (EMG) amplitude, single moto … WebbThe reasoning is that slow motor units impede ballistic movements while exclusive recruitment of fast units would be optimal. However a recent study demonstrated that the recruitment of slow motor units does not pose any such problem ( Holt et al., 2014 ).
