Time of Day Does Not Modulate Improvements in Motor Performance following a Repetitive Ballistic Motor Training Task
Figure 6
Relationship between motor performance (a), cortical excitability (b), and salivary cortisol concentration. Linear regression analysis revealed a nonsignificant ( < 0.01) relationship between acceleration ratio (max. acceleration post-MT/max. acceleration pre-MT) and the log of average salivary cortisol concentration (a). Linear regression analysis revealed a nonsignificant ( = 0.02) relationship between MEP facilitation ratio (MEP amplitude post-MT/MEP amplitude pre-MT) and the log of average salivary cortisol concentration (b). Data include morning (unfilled circles) and evening (filled circles) experiments.
