The Comparison of Different Stretching Intensities on the Range of Motion and Muscle Stiffness of the Quadriceps Muscles

open access: yesFrontiers in Physiology, 2021
Muscle strain is one of the most frequent sports injuries, having the rectus femoris (RF) muscle as the reported preferred site of quadriceps muscle strain. The decrease muscle stiffness could be an effective RF muscle strain prevention.

3D Muscle Deformation Mapping at Submaximal Isometric Contractions: Applications to Aging Muscle

open access: yesFrontiers in Physiology, 2020
3D strain or strain rate tensor mapping comprehensively captures regional muscle deformation. While compressive strain along the muscle fiber is a potential measure of the force generated, radial strains in the fiber cross-section may provide information

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 ...

Regional heterogeneity in muscle fiber strain: The role of fiber architecture

open access: yesFrontiers in Physiology, 2014
The force, mechanical work and power produced by muscle fibers are profoundly affected by the length changes they undergo during a contraction. These length changes are in turn affected by the spatial orientation of muscle fibers within a muscle (fiber ...

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 ...

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 ...

Muscle Engagement Monitoring Using Self-Adhesive Elastic Nanocomposite Fabrics

open access: yesSensors, 2022
Insight into, and measurements of, muscle contraction during movement may help improve the assessment of muscle function, quantification of athletic performance, and understanding of muscle behavior, prior to and during rehabilitation following ...
