Distribution of motor unit properties across human muscles
J Duchateau, RM Enoka - Journal of Applied Physiology, 2022 - journals.physiology.org
The purpose of our review was to compare the distribution of motor unit properties across
human muscles of different sizes and recruitment ranges. Although motor units can be …

Failure to expand the motor unit size to compensate for declining motor unit numbers distinguishes sarcopenic from non‐sarcopenic older men
Key points The age‐related loss of muscle mass is related to the loss of innervating motor
neurons and denervation of muscle fibres. Not all denervated muscle fibres are degraded; …
