Implication

Hypothesis-generating for rat motor unit physiology; leaves open translation to human neuromuscular function.

Structured PICO

Population

Anesthetized adult male Sprague-Dawley rats in situ (n=70 gastrocnemius muscle units and n=98 tibial motoneurons)

Intervention

Current injection into innervating motoneurons and stimulation at 25 Hz

Outcome

Contractile properties of gastrocnemius muscle units and electrophysiological properties of their innervating motoneuronssurrogate

Slow muscle units are innervated by motoneurons with significantly higher afterhyperpolarization times-to-peak and half-decay times compared to fast units in rat gastrocnemius.
