Fatigue of elbow flexor muscles in younger and older adults

Abstract: The aim of this study was to assess differences in the behavior of fatigue‐related measures of neuromuscular function between younger (n = 10; 20–35 years) and older (n = 11; >65 years) healthy adults. Measures reflecting changes in voluntary activation, neuromuscular propagation, metabolite build‐up, and excitation‐contraction coupling processes were taken before, during, and after a sustained maximum elbow‐flexion fatigue task. We found a greater role for a failure in voluntary activation (central fatigue) i… Show more

“…The mean value of 95.6±3.1 % across all subjects is comparable to previous studies which used TMS (Hunter et al 2006Todd et al 2003Todd et al , 2004Todd et al , 2005 but slightly less than 97-98 % commonly reported with peripheral nerve stimulation (Allman and Rice 2001;Bilodeau et al 2001;Dalton et al 2010;De Serres and Enoka 1998;Jakobi and Rice 2002;Klein et al 2001;Todd et al 2003;Yue et al 1999). In the same subjects, a comparison of the two techniques revealed a lower activation score using TMS compared to peripheral nerve stimulation but the difference was not statistically significant and the authors noted caveats to comparing the two techniques (Todd et al 2003).…”

“…Preliminary studies make it evident that older adults are more resistant to fatigue than young adults when they execute prolonged and intermittent muscle contractions [43][44][45] . It is believed that this could be related to the greater capacity young adults have to produce strength when compared to older adults.…”

“…This has been attributed to a reduced voluntary activation (Bilodeau, 2001) and, to a great extent, to a reduction in muscle mass (Proctor et al, 1998), associated with alterations in hormone balance (Hakkinen and Pakarinen, 1993) and quantity and intensity of physical activity (Mälkiä et al, 1994).…”
