THE EFFECT OF PENNATION ANGLE CHANGES DURING CONTRACTION ON THE ESTIMATED TRICEPS SURAE MOMENT [PDF]
, 2008 INTRODUCTION: Forward dynamics simulations are important tools in biomechanics research but the accuracy of the muscle model parameters (such as pennation angle, optimal fiber length, force-velocity relationship, etc.) is critical for realistic force and

Correlation between age, muscle architecture, and muscle strength in children with Erb’s palsy
Bulletin of Faculty of Physical Therapy, 2021 Background Muscle weakness is a widespread problem in children with Erb’s palsy as it can cause changes in muscle architecture parameters, which can be detected by ultrasonography.

The Change of Pennation Angle of Medial Gastrocnemius on Different Heights of Heels
Indian Journal of Science and Technology, 2016 Objectives This study aims to investigate the effect of pennation angle and surface Electromyography (sEMG) activity of medial gastrocnemius on different heights of high heels by using ultrasonography and sEMG. Methods/Statistical Analysis: Twenty eight healthy young females participate in this study.

Gastrocnemius fascicles are shorter and more pennate throughout the first month following acute Achilles tendon rupture [PDF]
PeerJ, 2019 The purpose of this study was to characterize the short-term effects of Achilles tendon ruptures on medial gastrocnemius. We hypothesized that the fascicles of the medial gastrocnemius muscle of the injured Achilles tendon would be shorter and more ...

The Anatomical Record, EarlyView.Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

The Anatomical Record, EarlyView.Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.

Bite force estimates and morphological correlations of jaw muscles in parrots
The Anatomical Record, EarlyView.Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.
