METHODS: Our sample included 2017 observations from 715 participants (9-21 years; 338 girls).  Participants performed three S2LJ with hands-on-waist on a force platform (Leonardo Mechanograph, Novotec). Outcomes were maximum peak power (Pmax), Pmax\/mass, peak force\/body weight (Fmax\/BW), force efficiency, maximum jump height (Hmax), and velocity (Vmax). We used the LMS method to construct age- and  sex-specific percentile curves and mixed effects models to examine sex and ethnic differences. RESULTS: With the exception of Efficiency, mechanography outcomes were greater in girls (4-40%, p&lt;0.05) than boys at age 9. Boys&#8217; advantage in mechanography parameters emerged in adolescence (age 11-13 years; 3-65%, p&lt;0.05)  and persisted into young adulthood, except for Fmax\/BW which was not greater in boys until age 17 (4-10%, p&lt;0.05). Mechanography outcomes were 3-9% (p&lt;0.05) greater in Asian compared with white participants. CONCLUSIONS: We provide the first reference data for the S2LJ using the hands-on-waist protocol in children,  youth and young adults. These data support previous findings using freely moving  arms and can be used when evaluating muscle function in pediatric studies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>OBJECTIVES: To provide age- and sex-specific reference data for mechanography-derived parameters of muscle function in Canadian children and youth using<\/p>\n","protected":false},"author":22,"parent":0,"menu_order":0,"template":"","format":"standard","meta":{"_acf_changed":false},"tags":[1205,1840],"thema":[5870,5922,5924,5866,5868,5872],"produktgruppe":[5827],"literatur_kategorie":[7221],"class_list":["post-165390","literatur","type-literatur","status-publish","format-standard","hentry","tag-cmj","tag-sq","thema-basics","thema-clinical-application","thema-clinical-studies","thema-diagnostics-using-leonardo-pqct","thema-over-all-concept","thema-training-education","produktgruppe-leonardo-en","literatur_kategorie-clinical-studies"],"acf":[],"_links":{"self":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/165390","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur"}],"about":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/types\/literatur"}],"author":[{"embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/users\/22"}],"version-history":[{"count":0,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/165390\/revisions"}],"wp:attachment":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/media?parent=165390"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/tags?post=165390"},{"taxonomy":"thema","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/thema?post=165390"},{"taxonomy":"produktgruppe","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/produktgruppe?post=165390"},{"taxonomy":"literatur_kategorie","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur_kategorie?post=165390"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
