Further addition of concurrent cognitive demand at a high level showed similar perceived fatigue (1.67\/10) and physical demand (32\/100) but demonstrated higher muscle activity (0.239\u00a0volts) and lower muscle capacity retention (89.9%).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Applications<\/jats:title>\n            <jats:p>Findings demonstrate importance of tailoring cognitive demands based on gender and occupational settings, with moderate mental tasks during breaks offering the most favorable results overall, enhancing recovery and reducing muscle activity without compromising task performance.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1177\/00187208251332777","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T09:54:16Z","timestamp":1744278856000},"page":"1084-1100","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Cognitive Engagement on Physical Performance and Perceived Workload During Isometric Exertions of Index Finger"],"prefix":"10.1177","volume":"67","author":[{"given":"Sidharajsinh","family":"Jadeja","sequence":"first","affiliation":[{"name":"Rochester Institute of Technology, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6572-0912","authenticated-orcid":false,"given":"Pranav Madhav","family":"Kuber","sequence":"additional","affiliation":[{"name":"Rochester Institute of Technology, USA"}]},{"given":"Ehsan","family":"Rashedi","sequence":"additional","affiliation":[{"name":"Rochester Institute of Technology, USA"}]}],"member":"179","published-online":{"date-parts":[[2025,4,10]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00436747"},{"key":"e_1_3_4_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelekin.2006.06.005"},{"issue":"1","key":"e_1_3_4_4_1","first-page":"6","article-title":"Corollary discharges and fatigue-related symptoms: The role of attentional focus","volume":"6","author":"Bigliassi M.","year":"2015","unstructured":"Bigliassi M.
