Twenty-two males (age: 25.5 \u00b1 5.3 years) first performed maximal voluntary contractions (MVC) and submaximal isometric contractions of upper limb muscles at 25%, 50% and 75% MVC. Participants then executed repetitions of a functional activity simulating a load-lifting task above shoulder level, at 25%, 50% and 75% of their maximum activity (based on MVC). The low-frequency part of the accelerometer signal (&lt;5 Hz) was used to segment the six phases of the motion. EMG and MMG were both recorded during the entire experimental procedure. Root mean square (RMS) and mean power frequency (MPF) were selected as signal extraction features. During isometric contractions, EMG and MMG exhibited similar repeatability scores. They also shared similar RMS vs. force relationship, with RMS increasing to 75% MVC and plateauing to 100%. MPF decreased with increasing force to 75% MVC. In dynamic condition, RMSMMG exhibited higher sensitivity to changes in load than RMSEMG. These results confirm the feasibility of MMG measurements to be used during functional activities outside the laboratory. It opens new perspectives for future applications in sports science, ergonomics and human\u2013machine interface conception.<\/jats:p>","DOI":"10.3390\/s23187969","type":"journal-article","created":{"date-parts":[[2023,9,19]],"date-time":"2023-09-19T03:02:17Z","timestamp":1695092537000},"page":"7969","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Mechanomyographic Analysis for Muscle Activity Assessment during a Load-Lifting Task"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3968-6743","authenticated-orcid":false,"given":"Matthieu","family":"Correa","sequence":"first","affiliation":[{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 Paris-Saclay, CEDEX, 91405 Orsay, France"},{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 d\u2019Orl\u00e9ans, 45067 Orl\u00e9ans, France"},{"name":"Moten Technologies, 92800 Puteaux, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maxime","family":"Projetti","sequence":"additional","affiliation":[{"name":"Moten Technologies, 92800 Puteaux, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5140-7682","authenticated-orcid":false,"given":"Isabelle A.","family":"Siegler","sequence":"additional","affiliation":[{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 Paris-Saclay, CEDEX, 91405 Orsay, France"},{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 d\u2019Orl\u00e9ans, 45067 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7267-0236","authenticated-orcid":false,"given":"Nicolas","family":"Vignais","sequence":"additional","affiliation":[{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 Paris-Saclay, CEDEX, 91405 Orsay, France"},{"name":"Laboratoire CIAMS (Complexit\u00e9, Innovation, Activit\u00e9s Motrices et Sportives), Universit\u00e9 d\u2019Orl\u00e9ans, 45067 Orl\u00e9ans, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,19]]},"reference":[{"key":"ref_1","unstructured":"Gazzoni, M., Afsharipour, B., and Merletti, R.
