Contraction protocol 1: unfatigued muscle
torques
CONTRACTION, CONTRACTIONS
Participants performed 5 maximal effort contractions, where the trial that produced the largest torque was deemed the participants maximal voluntary contraction (MVC). Cortical and brachial plexus stimulation was delivered during initial baseline contractions, with a minimum of 2 min rest occurring between each effort. Target torques of 10%, 25%, 50%, and 75% MVC were then calculated from the measured MVC and displayed on a monitor. Participants performed 5 contractions for each target torque, whereby a maximal contraction was followed immediately by a submaximal contraction with no relaxation of the muscles when reducing force to submaximal contraction. Each maximal contraction within protocol 1 was a brief (~ 4 s) maximal contraction followed directly by a brief (4 s) submaximal contraction (Fig.
