Muscle excitation in elderly adults: The effects of training

Muscle membrane excitability is thought to decline with aging; the extent of this decline may be noninvasively assessed by measurement of the electrically evoked compound muscle action potential (M-wave). The intent of this study was two-fold: (1) to compare the M-wave in the brachioradialis (BR), tibialis anterior (TA), and thenar (TH) muscles of elderly (mean age = 66.3 +/- 3.7 years) and young (mean age = 31.2 +/- 4.9 years) adults, and (2) …
