Energy transfer in reactive movements as a function of individual stretch load

Frontiers in Physiology, 2023
Background: By directly recording electromyographic activity profiles and muscle-tendon interaction, this study aimed to elucidate the mechanisms why well-trained track and field athletes (experts) are able to outperform untrained individuals without ...

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 ...

Is Muscle Architecture Different in Athletes with a Previous Hamstring Strain? A Systematic Review and Meta-Analysis

Journal of Functional Morphology and Kinesiology, 2022
Hamstring strains are a frequent injury in sports and are characterized by a high recurrence rate. The aim of this review was to examine the muscle and tendon architecture in individuals with hamstring injury.

A model of fasciculation and sorting in mixed populations of axons

, 2011
We extend a recently proposed model (Chaudhuri et al., EPL 87, 20003 (2009)) aiming to describe the formation of fascicles of axons during neural development.

Faster movement speed results in greater tendon strain during the loaded squat exercise

Frontiers in Physiology, 2016
Introduction: Tendon dynamics influence movement performance and provides the stimulus for long-term tendon adaptation. As tendon strain increases with load magnitude and decreases with loading rate, changes in movement speed during exercise should ...

Persistent functional loss following ruptured Achilles tendon is associated with reduced gastrocnemius muscle fascicle length, elongated gastrocnemius and soleus tendon, and reduced muscle cross‐sectional area

Translational Sports Medicine, 2019
We examined muscle function, muscle architecture, and tendon length bilaterally in persons who experience a functional deficit 2 years after an Achilles tendon rupture. Eleven persons were investigated on the injured compared with the uninjured side 47 ±

Distribution of choline acetyltransferase (ChAT) immunoreactivity in the brain of the teleost cyprinus carpio [PDF]

, 2018
Cholinergic systems play a role in basic cerebral functions and its dysfunction is associated with deficit in neurodegenerative disease. Mechanisms involved in human brain diseases, are often approached by using fish models, especially cyprinids, given ...

Effect of Intermittent Cyclic Tensile Strain on Collagen Synthesis by Tenocytes in Isolated Fascicles

Journal of Biomechanical Science and Engineering, 2009
Intermittent pattern of mechanical stimulation has been demonstrated to possess different regulatory effects on cell metabolism in many connective tissues, but little is known about tenocyte responses. A previous study has shown that the application of a
