Functional compartmentalization of the anconeus: A three‐dimensional study of muscle morphology and innervation patterns

Journal of Anatomy, EarlyView.
In this anatomic study of anconeus utilizing dissection, digitization and 3D modeling, anconeus was found to have three distinct parts: proximal, distal, and deep. Each part had unique morphology, architecture and innervation, indicating different roles in forearm pronation, elbow extension, and joint stabilization.

Accuracy of gastrocnemius muscles forces in walking and running goats predicted by one-element and two-element Hill-type models [PDF]

, 2013
Hill-type models are commonly used to estimate muscle forces during human and animal movement —yet the accuracy of the forces estimated during walking, running, and other tasks remains largely unknown.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Rate of force development relationships to muscle architecture and contractile behavior in the human vastus lateralis

Scientific Reports, 2022
In this study, we tested the hypotheses that (i) rate of force development (RFD) is correlated to muscle architecture and dynamics and that (ii) force–length–velocity properties limit knee extensor RFD.

Cross‐education of lower limb muscle strength following resistance exercise training in males and females: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract Cross‐education describes the training of one limb that leads to performance enhancements in the contralateral untrained limb, driven by neural changes rather than muscle adaptation. In this systematic review and meta‐analysis, we aimed to evaluate the efficacy of cross‐education (vs. a control group) via resistance exercise training (RET) for

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae) [PDF]

, 2014
Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood ...

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

Journal of Anatomy, Volume 248, Issue 6, Page 890-901, June 2026.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

The effects of static stretching programs on muscle strength and muscle architecture of the medial gastrocnemius.

PLoS ONE, 2020
IntroductionStatic stretching (SS) program are widely used in clinical and athletic settings. Many previous studies investigate the effect of SS program on muscle strength and muscle architecture (muscle thickness, and pennation angleh).
