As the debate about the existence of CF and its underlying mechanisms is still ongoing and may be protocol-dependent, our study investigated whether CF can be evoked using fast repetitive movements at maximal speed, which have been shown to induce fatigability on the supraspinal level. These rapidly repeating movements induce motor slowing, an involuntary decrease in movement speed. We evoke fatigability through maximal speed finger tapping with one hand and subsequently assessed fast finger tapping performance of the contralateral hand. In two independent cohorts (\n                    <jats:italic>n<\/jats:italic>\n                    \u202f=\u202f16,\n                    <jats:italic>n<\/jats:italic>\n                    \u202f=\u202f30), 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 \u201cmovement reserve.\u201d Notably, even a brief 10\u202fs 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.\n                  <\/jats:p>","DOI":"10.3389\/fnhum.2026.1782120","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T05:33:02Z","timestamp":1775539982000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Finger tapping at maximal speed evokes crossover fatigability in the other hand"],"prefix":"10.3389","volume":"20","author":[{"given":"Caroline","family":"Heimhofer","sequence":"first","affiliation":[{"name":"Neural Control of Movement Lab, Department of Health Sciences and Technology, ETH Zurich","place":["Zurich, Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Imhof","sequence":"additional","affiliation":[{"name":"Neural Control of Movement Lab, Department of Health Sciences and Technology, ETH Zurich","place":["Zurich, Switzerland"]},{"name":"Neuroscience Center Zurich (ZNZ), University of Zurich, University and Balgrist Hospital Zurich, ETH Zurich","place":["Zurich, Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ingrid","family":"Odermatt","sequence":"additional","affiliation":[{"name":"Neural Control of Movement Lab, Department of Health Sciences and Technology, ETH Zurich","place":["Zurich, Switzerland"]},{"name":"School of Psychology, Queen\u2019s University Belfast","place":["Belfast, United Kingdom"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc","family":"B\u00e4chinger","sequence":"additional","affiliation":[{"name":"Neural Control of Movement Lab, Department of Health Sciences and Technology, ETH Zurich","place":["Zurich, Switzerland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole","family":"Wenderoth","sequence":"additional","affiliation":[{"name":"Neural Control of Movement Lab, Department of Health Sciences and Technology, ETH Zurich","place":["Zurich, Switzerland"]},{"name":"Neuroscience Center Zurich (ZNZ), University of Zurich, University and Balgrist Hospital Zurich, ETH Zurich","place":["Zurich, Switzerland"]},{"name":"Future Health Technologies, Campus for Research Excellence and Technological Enterprise (CREATE), Singapore-ETH Centre","place":["Singapore, Singapore"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1301","DOI":"10.1111\/sms.12596","article-title":"Unilateral elbow flexion fatigue modulates corticospinal responsiveness in non-fatigued contralateral biceps brachii","volume":"26","author":"Aboodarda","year":"2016","journal-title":"Scand.
