Supports motor unit metabolic homogeneity in animal models; leaves open translation to human fatigue mechanisms or clinical applications.
Muscle fibers within a single motor unit exhibit similar metabolic enzyme profiles, which correlate with the unit's resistance to fatigue.
Nemeth et al. (1981) studied this question.
