Neural hyperexcitability in hyperkalemic periodic paralysis.

abstract：INTRODUCTION:This investigation aimed to: (1) confirm whether women were more vulnerable to the negative neuromuscular adaptations elicited by muscle unloading and if so, (2) determine which physiological mechanism(s) explain those gender-related differences. METHODS:Healthy young men (20.7 ± 0.3 years) and women (20....
