We utilized surface electromyography (sEMG) in 36 healthy young individuals aged 24 (\u00b11.1) years to identify muscle activity during a non-gait imagery task (non-GI), as well as GI tasks before (GI-1) and after the execution of walking (GI-2), with assessments performed in both sitting and standing postures. The sEMG was recorded on both lower limbs on the tibialis anterior (TA) and on the gastrocnemius medialis (GM) for all tested tasks. As a result, a significant muscle activity decrease was found in the right TA for GI-1 compared to GI-2 in both sitting (p = 0.008) and standing (p = 0.01) positions. In the left TA, the activity decreased in the sitting posture during non-GI (p = 0.004) and GI-1 (p = 0.009) in comparison to GI-2. No differences were found for GM. The subjective level of imagination difficulty improved for GI-2 in comparison to GI-1 in both postures (p &lt; 0.001). Previous sensorimotor experience with real gait execution and sitting posture potentiate TA activity decrease during GI. These findings contribute to the understanding of neural mechanisms beyond GI.<\/jats:p>","DOI":"10.3390\/brainsci13111605","type":"journal-article","created":{"date-parts":[[2023,11,20]],"date-time":"2023-11-20T00:30:50Z","timestamp":1700440250000},"page":"1605","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["How Posture and Previous Sensorimotor Experience Influence Muscle Activity during Gait Imagery in Young Healthy Individuals"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4317-8557","authenticated-orcid":false,"given":"Barbora","family":"Kol\u00e1\u0159ov\u00e1","sequence":"first","affiliation":[{"name":"Department of Clinical Rehabilitation, Faculty of Health Sciences, Palack\u00fd University Olomouc, Hn\u011bvot\u00ednsk\u00e1 976\/3, 775 15 Olomouc, Czech Republic"},{"name":"Department of Rehabilitation, University Hospital Olomouc, Zdravotn\u00edk\u016f 248\/7, 779 00 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marek","family":"Tomsa","sequence":"additional","affiliation":[{"name":"Department of Clinical Rehabilitation, Faculty of Health Sciences, Palack\u00fd University Olomouc, Hn\u011bvot\u00ednsk\u00e1 976\/3, 775 15 Olomouc, Czech Republic"},{"name":"Department of Rehabilitation, University Hospital Olomouc, Zdravotn\u00edk\u016f 248\/7, 779 00 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Petr","family":"Kol\u00e1\u0159","sequence":"additional","affiliation":[{"name":"Department of Clinical Rehabilitation, Faculty of Health Sciences, Palack\u00fd University Olomouc, Hn\u011bvot\u00ednsk\u00e1 976\/3, 775 15 Olomouc, Czech Republic"},{"name":"Department of Rehabilitation, University Hospital Olomouc, Zdravotn\u00edk\u016f 248\/7, 779 00 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6020-7658","authenticated-orcid":false,"given":"Hana","family":"Haltmar","sequence":"additional","affiliation":[{"name":"Department of Clinical Rehabilitation, Faculty of Health Sciences, Palack\u00fd University Olomouc, Hn\u011bvot\u00ednsk\u00e1 976\/3, 775 15 Olomouc, Czech Republic"},{"name":"Department of Rehabilitation, University Hospital Olomouc, Zdravotn\u00edk\u016f 248\/7, 779 00 Olomouc, Czech Republic"},{"name":"Department of Natural Sciences in Kinanthropology, Faculty of Physical Culture, Palack\u00fd University Olomouc, t\u0159\u00edda M\u00edru 117, 771 11 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tereza","family":"Diatelov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Clinical Rehabilitation, Faculty of Health Sciences, Palack\u00fd University Olomouc, Hn\u011bvot\u00ednsk\u00e1 976\/3, 775 15 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6220-4450","authenticated-orcid":false,"given":"Miroslav","family":"Janura","sequence":"additional","affiliation":[{"name":"Department of Natural Sciences in Kinanthropology, Faculty of Physical Culture, Palack\u00fd University Olomouc, t\u0159\u00edda M\u00edru 117, 771 11 Olomouc, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1265","DOI":"10.1007\/s00702-007-0763-z","article-title":"Motor imagery and action observation: Cognitive tools for rehabilitation","volume":"114","author":"Mulder","year":"2007","journal-title":"J.
