While muscle mass, determined by DXA and MRI, did not correlate with performance in the older adults, power per body mass, determined from a countermovement jump, did correlate. The 40% lower jumping power observed in older adults (p &lt; .05) was due to a lower take-off velocity, which explained 34% and 42% of the variance in 6MWD in older women and men, respectively (p &lt; .01). The lower velocity was partly attributable to the higher body mass to maximal force ratio, but most was due to  a lower intrinsic muscle speed. While changes in muscle function explain part of  the age-related reduction in functional performance, ~60% of the deficit remains  to be explained.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>To investigate reasons for the age-related reduction in physical function, we determined the relationships between muscle size, strength, and power<\/p>\n","protected":false},"author":22,"parent":0,"menu_order":0,"template":"","format":"standard","meta":{"_acf_changed":false},"tags":[],"thema":[5922,5924,5866],"produktgruppe":[5827],"literatur_kategorie":[7221],"class_list":["post-165914","literatur","type-literatur","status-publish","format-standard","hentry","thema-clinical-application","thema-clinical-studies","thema-diagnostics-using-leonardo-pqct","produktgruppe-leonardo-en","literatur_kategorie-clinical-studies"],"acf":[],"_links":{"self":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur\/165914","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\/165914\/revisions"}],"wp:attachment":[{"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/media?parent=165914"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/tags?post=165914"},{"taxonomy":"thema","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/thema?post=165914"},{"taxonomy":"produktgruppe","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/produktgruppe?post=165914"},{"taxonomy":"literatur_kategorie","embeddable":true,"href":"https:\/\/stratec-med.com\/en\/wp-json\/wp\/v2\/literatur_kategorie?post=165914"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
