[HTML][HTML] Advances in imaging for assessing the design and mechanics of skeletal muscle in vivo

TJM Dick, F Hug - Journal of Biomechanics, 2023 - Elsevier
Skeletal muscle is the engine that powers what is arguably the most essential and defining
feature of human and animal life—locomotion. Muscles function to change length and …

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 …

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 …

Eccentric exercise≠ eccentric contraction

P Tecchio, BJ Raiteri, D Hahn - Journal of Applied …, 2024 - journals.physiology.org
Whether eccentric exercise involves active fascicle stretch is unclear due to muscle-tendon
unit (MTU) series compliance. Therefore, this study investigated the impact of changing the …

[HTML][HTML] Residual force enhancement decreases when scaling from the single muscle fiber to joint level in humans

A Hinks, KBE Jacob, MA Patterson, BE Dalton… - Journal of Sport and …, 2025 - Elsevier
Background Residual force enhancement (rFE), defined as increased isometric force
following active lengthening compared to a fixed-end isometric contraction at the same …

Unlocking the benefit of active stretch: the eccentric muscle action, not the preload, maximizes muscle-tendon unit stretch-shortening cycle performance

T Goecking, D Holzer, D Hahn… - Journal of Applied …, 2024 - journals.physiology.org
Stretch-shortening cycles (SSCs) outperform shortening contractions preceded by isometric
contractions in terms of enhanced force/torque, work, and power production during …

UltraTimTrack: a Kalman-filter-based algorithm to track muscle fascicles in ultrasound image sequences

TJ van der Zee, P Tecchio, D Hahn, BJ Raiteri - PeerJ Computer Science, 2025 - peerj.com
Background Brightness-mode (B-mode) ultrasound is a valuable tool to non-invasively
image skeletal muscle architectural changes during movement, but automatically tracking …

Impact of Starting Knee Flexion Angle on Muscle Activity and Performance during Plyometrics without Jum**

M Torres-Banduc, I Chirosa-Ríos, L Chirosa-Ríos… - Sensors, 2023 - mdpi.com
Most of the existing research has focused on jump plyometrics, where landing reaction
forces must be dissipated among lower limb articulations. In contrast, the investigation of …

Impact of different muscle-lengthening amplitudes combined with electrical nerve stimulation on torque production

A Pineau, A Martin, R Lepers… - Journal of …, 2025 - journals.physiology.org
This study investigated torque production resulting from the combined application of wide-
pulse neuromuscular electrical stimulation (NMES), delivered over the posterior tibial nerve …

Characterizing residual and passive force enhancements in cardiac myofibrils

S Han, K Boldt, V Joumaa, W Herzog - Biophysical Journal, 2023 - cell.com
Residual force enhancement (RFE), an increase in isometric force after active stretching of a
muscle compared with the purely isometric force at the corresponding length, has been …
