Rethinking the physiological cross-sectional area of skeletal muscle reveals the mechanical advantage of pennation

Royal Society Open Science
The shape of skeletal muscle varies remarkably—with important implications for locomotor performance. In many muscles, the fibres are arranged at an angle relative to the tendons’ line of action, termed the pennation angle.

Changes in tibialis anterior architecture affect the amplitude of surface electromyograms [PDF]

, 2010
BACKGROUND: Variations in the amplitude of surface electromyograms (EMGs) are typically considered to advance inferences on the timing and degree of muscle activation in different circumstances. Surface EMGs are however affected by factors other than the

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

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

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

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.

The neuromuscular determinants of unilateral jump performance in soccer players are direction-specific [PDF]

, 2017
Purpose: To investigate differences in neuromuscular factors between elite and non-elite players, and to establish which factors underpin direction-specific unilateral jump performance.

Nutrition and rehabilitation after anterior cruciate ligament reconstruction: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose As the impact of nutrition on rehabilitation and return to sport (RTS) after ACL reconstruction (ACLR) remains largely unexplored, this review aimed to review the current evidence on the role of nutrition in rehabilitation outcomes for ACLR patients, with as ultimate goal a safer and more successful RTS.
