Muscle spindles in human tibialis anterior encode muscle fascicle length changes

open access: yesJournal of Neurophysiology, 2017
Muscle spindles provide exquisitely sensitive proprioceptive information regarding joint position and movement. Through passively driven length changes in the muscle-tendon unit (MTU), muscle spindles detect joint rotations because of their in-parallel mechanical linkage to muscle fascicles.

Effect of plyometric training on the fascicle length of the gastrocnemius medialis muscle [PDF]

open access: yesJournal of Physical Therapy Science, 2020
[Purpose] The present study aimed to determine the effects of eccentric calf raise exercise, which has the characteristics of plyometric training, on the fascicle length and muscle thickness of the gastrocnemius medialis muscle and range of motion of the ankle using ultrasonography. [Participants and Methods] Twenty-one healthy volunteers were randomly

Muscle fascicle length adaptations to high-velocity training in young adults with cerebral palsy [PDF]

open access: yesFrontiers in Sports and Active Living
IntroductionIn individuals with Cerebral Palsy (CP), both muscle cross-sectional area and fascicle length are reduced, contributing to decreased muscle strength, muscle shortening velocity and muscle mechanical power output, particularly in the ...

A novel diffusion‐tensor MRI approach for skeletal muscle fascicle length measurements [PDF]

open access: yesPhysiological Reports, 2016
AbstractMusculoskeletal (dys‐)function relies for a large part on muscle architecture which can be obtained using Diffusion‐Tensor MRI (DT‐MRI) and fiber tractography. However, reconstructed tracts often continue along the tendon or aponeurosis when using conventional methods, thus overestimating fascicle lengths. In this study, we propose a new method

Automatic tracking of medial gastrocnemius fascicle length during human locomotion

open access: yesJournal of Applied Physiology, 2011
During human locomotion lower extremity muscle-tendon units undergo cyclic length changes that were previously assumed to be representative of muscle fascicle length changes. Measurements in cats and humans have since revealed that muscle fascicle length changes can be uncoupled from those of the muscle-tendon unit.

Relationship Between Sprint Performance and Muscle Fascicle Length in Female Sprinters.

open access: yesJournal of PHYSIOLOGICAL ANTHROPOLOGY and Applied Human Science, 2001
The purpose of this study was to investigate the relationship between sprint performance and architectural characteristics of leg muscles in 26 female 100-m sprinters. Pennation angle and muscle thickness of the vastus lateralis (VL) and gastrocnemius medialis (GM) and lateralis (GL) muscles were measured by B-mode ultrasonography, and fascicle length ...

Comparison between Short, Medium, and Long Fields of View in Estimating Bicep Femoris Fascicle Length [PDF]

open access: yesMuscles
Measuring the bicep femoris long head fascicle length via the use of diagnostic ultrasound has become common practice within elite sport, using single images of between 4 and 6 cm.

High Velocity Passive Stretching Mimics Eccentric Exercise in Cerebral Palsy and May Be Used to Increase Spastic Muscle Fascicle Length [PDF]

open access: yesBioengineering
Muscle fascicles are shorter and stiffer than normal in spastic Cerebral Palsy (CP). Increasing fascicle length (FL) has been attempted in CP, the outcomes of which have been unsatisfactory.

Unexpected Fascicle Length Changes In Denervated Feline Soleus Muscle During Stance Phase Of Walking [PDF]

open access: yesScientific Reports, 2015
AbstractAfter surgical repair of traumatically severed peripheral nerves, associated muscles are paralyzed for weeks. Little is known about fascicle length changes in paralyzed muscles during locomotion. The aim of this study was to investigate to what extent, if any, muscle fascicles of denervated feline soleus (SO) change length during stance of ...

The force-length relation of the young adult human tibialis anterior [PDF]

open access: yesPeerJ, 2023
Background Knowledge of the muscle’s lengths at which maximum active isometric force is attained is important for predicting forces during movement. However, there is limited information about the in vivo force-length properties of a human muscle that ...
