Experiment 1
fatigue
We analyzed the MVC data using two-way repeated-measures ANOVAs with TASK (fatigue, control) and TIME (MVC1 to MVC7; 7 time points) as the within-subjects' factors as well as the neurophysiological data (CBI, MEP amplitude, SICI, and ICF) using separate two-way repeated-measures ANOVAs with TASK (fatigue, control) and TIME (B, P1, P2) as the within-subjects' factors. We used Greenhouse–Geiser correction to adjust for lack of sphericity in the repeated-measures ANOVA examining changes in MEP amplitude.
