Finger tapping at maximal speed evokes crossover fatigability in the other hand
= 30), we demonstrated that CF can indeed be induced using a motor slowing paradigm. Our findings show that CF manifests as a reduced initial tapping speed in the other, non-exercised hand and as a reduced "movement reserve." Notably, even a brief 10 s period of maximal speed finger tapping was sufficient to evoke this CF effect. Based on our current results and on previous findings, we suggest that CF evoked by motor slowing is unlikely to emerge peripherally and most likely reflects supraspinal mechanisms.
