The Energy of Muscle Contraction. I. Tissue Force and Deformation During Fixed-End Contractions

open access: yesFrontiers in Physiology, 2020
During contraction the energy of muscle tissue increases due to energy from the hydrolysis of ATP. This energy is distributed across the tissue as strain-energy potentials in the contractile elements, strain-energy potential from the 3D deformation of ...

Temporal effects of mechanical loading on deformation-induced damage in skeletal muscle tissue [PDF]

open access: yes, 2010
Mechanical loading of soft tissues covering bony prominences can cause skeletal muscle damage, ultimately resulting in a severe pressure ulcer termed deep tissue injury.

Notch signaling pathway in human vascular smooth muscle cell differentiation [PDF]

open access: yes, 2006
Notch receptor-ligand interactions are a highly conserved mechanism, originally described in developmental studies using Drosophilae, that regulate inter-cell communication and dictate, in part, vascular smooth muscle cell (VSMC) fate in response to ...

Stretching Your Energetic Budget: How Tendon Compliance Affects the Metabolic Cost of Running. [PDF]

open access: yesPLoS ONE, 2016
Muscles attach to bones via tendons that stretch and recoil, affecting muscle force generation and metabolic energy consumption. In this study, we investigated the effect of tendon compliance on the metabolic cost of running using a full-body ...

Noninvasive Estimation of Myosin Heavy Chain Composition in Human Skeletal Muscle [PDF]

open access: yes, 2011
Purpose: Information on muscle fiber type composition is of great importance in muscle physiology and athletic performance. Because there are only a few techniques available that noninvasively and accurately provide an estimate of muscle fiber type ...

Imaging displacement and strain in the medial gastrocnemius muscle during ankle-joint motion using 2D-ciné DENSE MRI [PDF]

open access: yes, 2011
Skeletal muscle structure has been defined on both macro and microscopic levels by gross dissection, light- and electron-microscopy. The basic physiological building blocks involve the electromechanical coupling between interlinking actin and myosin ...

A biomechanical paradox in fish: swimming and suction feeding produce orthogonal strain gradients in the axial musculature

open access: yesScientific Reports, 2021
The axial musculature of fishes has historically been characterized as the powerhouse for explosive swimming behaviors. However, recent studies show that some fish also use their ‘swimming’ muscles to generate over 90% of the power for suction feeding ...

Relationships among hamstring muscle optimal length and hamstring flexibility and strength

open access: yesJournal of Sport and Health Science, 2017
Background: Hamstring muscle strain injury (hamstring injury) due to excessive muscle strain is one of the most common injuries in sports. The relationships among hamstring muscle optimal lengths and hamstring flexibility and strength were unknown, which

Possible factors related to increased strain of the iliotibial band in recreational female runners

open access: yesJournal of Physical Fitness and Sports Medicine, 2020
Increased strain of the iliotibial band (ITB) is a key factor of ITBS aggravation. There are several internal risk factors contributing to increased ITB strain; gender (female), knee malalignment (genu varum > genu valgus), deteriorated muscle ...
