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.

Supraspinal Fatigue Impedes Recovery From a Low-Intensity Sustained Contraction in Old Adults [PDF]

open access: yes, 2011
This study determined the contribution of supraspinal fatigue and contractile properties to the age difference in neuromuscular fatigue during and recovery from a low-intensity sustained contraction.

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.

Physiological, aerodynamic and geometric constraints of flapping account for bird gaits, and bounding and flap-gliding flight strategies [PDF]

open access: yes, 2016
Aerodynamically economical flight is steady and level. The high-amplitude flapping and bounding flight style of many small birds departs considerably from any aerodynamic or purely mechanical optimum.

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

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.

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 ...

Muscle pain induced by static contraction is modulated by transient receptor potential vanilloid 1 and ankyrin 1 receptors

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2022
Molecular mechanisms involved in the development of muscle pain induced by static contraction are not completely elucidated. This study aimed to evaluate the involvement of the transient receptor potential vanilloid 1 (TRPV1) and the transient receptor ...
