Influence of different knee and ankle ranges of motion on the elasticity of triceps surae muscles, Achilles tendon, and plantar fascia

Scientific Reports, 2020
Stiffness is a valuable indicator of the functional capabilities of muscle-tendon-fascia. Twenty healthy subjects participated in this study in which the passive elastic properties of the medial gastrocnemius (MG), lateral gastrocnemius (LG), soleus ...

3D curvature of muscle fascicles in triceps surae

Journal of Applied Physiology, 2014
Muscle fascicles curve along their length, with the curvatures occurring around regions of high intramuscular pressure, and are necessary for mechanical stability. Fascicles are typically considered to lie in fascicle planes that are the planes visualized during dissection or two-dimensional (2D) ultrasound scans.

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth

Journal of Anatomy, EarlyView.
Muscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

Influence of local pressure on athetoid,electromyogram of spastic paraplegia in water,and influence of oxygen inhalation on the tone of voice in athetoid of cerebral palsy.Prelim.rept. [PDF]

, 1963
As described in the foregoing, a certain degree of desirable effect can be recognized in every instance of the present trials. However, in order to apply these methods in clinics it is necessary to carry out further studies on the mechanism that operates

Force-sharing within the Triceps Surae: An Achilles Heel in Achilles Tendinopathy

Medicine & Science in Sports & Exercise, 2019
Purpose The primary aim of this study was to determine whether the distribution of force between the three heads of the triceps surae differs between people with Achilles tendinopathy and controls.

Functional morphology of trabecular bone in the calcaneus of African apes

Journal of Anatomy, EarlyView.
Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

The effects of proprioceptive weighting changes on posture control in patients with chronic low back pain: a cross-sectional study

Frontiers in Neurology, 2023
IntroductionPatients with chronic low back pain (CLBP) exhibit changes in proprioceptive weighting and impaired postural control. This study aimed to investigate proprioceptive weighting changes in patients with CLBP and their influence on posture ...

Muscle-Specific Effective Mechanical Advantage and Joint Impulse in Weightlifting [PDF]

, 2016
Lifting greater loads during weightlifting exercises may theoretically be achieved through increasing the magnitudes of net joint impulses or manipulating the joints’ effective mechanical advantage (EMA).

Are joint torque models limited by an assumption of monoarticularity? [PDF]

, 2012
This study determines whether maximal voluntary ankle plantar flexor torque could be more accurately represented using a torque generator that is a function of both knee and ankle kinematics.

Locomotor muscle dysfunction and rehabilitative exercise training in fibrotic interstitial lung disease: Where are we at and where could we go?

Experimental Physiology, EarlyView.
Abstract Exercise limitation is a cardinal feature of fibrotic interstitial lung disease arising from pulmonary gas exchange, respiratory mechanical and cardio‐circulatory abnormalities. More recently, it has been recognized that impairment in locomotor muscle function (e.g., reduced muscle mass/strength or heightened fatigability) might also play a ...
