Activation analysis of the lower limb muscles of cyclists during pedaling

open access: yesNihon Kikai Gakkai ronbunshu, 2020
It is important to elucidate the lower limb motion based on the activation of lower limb muscles during pedaling to improve pedaling performance of cyclists.

Isometric contraction induces transient increase of REDD1 expression in non‐contracted muscles partly through glucocorticoids

open access: yesPhysiological Reports, 2023
This study investigated whether muscle contraction induces expression of regulated in development and DNA damage 1 (REDD1), a potent inhibitor of mTORC1, in mice muscle.

The p21‐activated kinase 2 (PAK2), but not PAK1, regulates contraction‐stimulated skeletal muscle glucose transport

open access: yesPhysiological Reports, 2020
Aim Muscle contraction stimulates skeletal muscle glucose transport. Since it occurs independently of insulin, it is an important alternative pathway to increase glucose transport in insulin‐resistant states, but the intracellular signaling mechanisms ...

The energy of muscle contraction. II. Transverse compression and work [PDF]

open access: yes, 2020
In this study we reproduced this compression-induced reduction in muscle force through the use of a three-dimensional finite element model of contracting muscle. The model used the principle of minimum total energy and allowed for the redistribution of energy through different strain energy-densities; this allowed us to determine the importance of the ...

Voluntary Muscle Contraction Detection Algorithm Based on LSTM for Muscle Quality Measurement Algorithm

open access: yesApplied Sciences, 2021
In this paper, we propose the long–short-term memory (LSTM)-based voluntary and non-voluntary (VNV) muscle contraction classification algorithm in an electrical stimulation (ES) environment.

The energy of muscle contraction. I. Tissue force and deformation during isometric contractions [PDF]

open access: yes, 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 the base-material tissue (containing cellular and ECM effects), energy related to changes in the ...

A new paradigm for muscle contraction [PDF]

open access: yesFrontiers in Physiology, 2015
Muscle contraction has fascinated lay people and scientists for centuries. However, a good understanding of how muscle contraction occurs seemed only possible once microscopy techniques had evolved to a level where basic structural features, such as the regular cross striation patterns of fibers, could be observed in the late 19th century. In the early

A DIC based technique to measure the contraction of a skeletal muscle engineered tissue [PDF]

open access: yes, 2016
Tissue engineering is a multidisciplinary science based on the application of engineering approaches to biologic tissue formation. Engineered tissue internal organization represents a key aspect to increase biofunctionality before transplant and, as ...

Water and Muscle Contraction [PDF]

open access: yesInternational Journal of Molecular Sciences, 2008
The interaction between water and the protein of the contractile machinery as well as the tendency of these proteins to form geometrically ordered structures provide a link between water and muscle contraction. Protein osmotic pressure is strictly related to the chemical potential of the contractile proteins, to the stiffness of muscle structures and ...

Do differences in levels, types, and duration of muscle contraction have an effect on the degree of post-exercise depression?

open access: yesFrontiers in Human Neuroscience, 2016
We conducted two experiments to determine how differences in muscle contraction levels, muscle contraction types, and movement duration affect degree of post-exercise depression (PED) after non-exhaustive, repetitive finger movement.
