Although reducing blood oxygen saturation (SpO2) can cause rapid changes in corticospinal-motoneuronal activity, few studies have examined the direct consequences that hypoxia has on muscle activation. The purpose of this study was to examine how severe acute hypoxia affects firing rate and recruitment characteristics of a population of motor units (MU) in the biceps brachii. Given that the amplitude of interference EMG is often reduced with hypoxia, it was hypothesised that (MU) firing rate would decrease, accompanied by an increase in MU recruitment threshold.
