Muscular strength and power are correlated with motor unit action potential amplitudes, but not myosin heavy chain isoforms in sedentary males and females
It remains unclear if the sizes of higher-threshold motor units (MU) are associated with
muscular strength and power. Therefore, the purpose of this study was to examine sex …
