Mechanisms of enhanced force production in lengthening (eccentric) muscle contractions

W Herzog - Journal of Applied Physiology, 2014 - journals.physiology.org
In contrast to isometric and shortening contractions, many observations made on actively
lengthening muscles cannot be readily explained with the sliding filament and cross-bridge …

W Seiberl, GA Power, D Hahn - Journal of electromyography and …, 2015 - Elsevier
Following an active lengthening contraction while maintaining activation constant, isometric
force is elevated above that of a purely isometric contraction at the same final muscle length …

Increased residual force enhancement in older adults is associated with a maintenance of eccentric strength

GA Power, CL Rice, AA Vandervoort - PLoS one, 2012 - journals.plos.org

is well maintained during lengthening muscle actions (ie, eccentric strength) in old age …

Residual force depression is not related to positive muscle fascicle work during submaximal voluntary dorsiflexion contractions in humans

BJ Raiteri, L Lauret, D Hahn - The Journal of Physiology, 2024 - Wiley Online Library
Residual force depression (rFD) following active muscle shortening is assumed to correlate
most strongly with muscle work, but this has not been tested during voluntary contractions in …

The history-dependent features of muscle force production: A challenge to the cross-bridge theory and their functional implications

D Hahn, S Han, V Joumaa - Journal of Biomechanics, 2023 - Elsevier
The cross-bridge theory predicts that muscle force is determined by muscle length and the
velocity of active muscle length changes. However, before the formulation of the cross …
