Combined DTI Tractography and Functional MRI Study of the Language Connectome in Healthy Volunteers: Extensive Mapping of White Matter Fascicles and Cortical Activations. [PDF]

PLoS ONE, 2016
Despite a better understanding of brain language organization into large-scale cortical networks, the underlying white matter (WM) connectivity is still not mastered.

Pre-activation affects the effect of stretch-shortening cycle by modulating fascicle behavior

Biology Open, 2019
The torque attained during active shortening is enhanced after an active stretch (stretch-shortening cycle, SSC). This study examined the influence of pre-activation on fascicle behavior and the SSC effect.

Muscle Fibre Architecture of Thoracic and Lumbar Longissimus Dorsi Muscle in the Horse

Animals, 2021
As the longissimus dorsi muscle is the largest muscle in the equine back, it has great influence on the stability of the spine and facilitates proper locomotion.

Fascicle Length of Gastrocnemius Muscles in Monozygous Twins.

Journal of PHYSIOLOGICAL ANTHROPOLOGY and Applied Human Science, 2002
A large inter-individual variation is seen in muscle fascicle length of the athletes but the reasons for this phenomenon are unclear. The purpose of this study was to determine whether genetic factors contribute to the variances in muscle architectural characteristics.

The mechanisms of adaptation for muscle fascicle length changes with exercise: Implications for spastic muscle

Medical Hypotheses, 2020
We are proposing optimal training conditions that can lead to an increase in the number of serial sarcomeres (SSN) and muscle fascicle length (FL) in spastic muscles. Therapeutic interventions for increasing FL in clinical populations with neurological origin, in whom relative shortness of muscle fascicles contributed to the presentation of symptoms ...

Change in length of relaxed muscle fascicles and tendons with knee and ankle movement in humans [PDF]

The Journal of Physiology, 2002
Ultrasonography was used to measure changes in length of muscle fascicles in relaxed human tibialis anterior and gastrocnemius during passively imposed changes in joint angle. Changes in the length of muscle fascicles were compared to changes in the length of the whole muscle‐tendon units calculated from joint angles and anthropometric data.

Changes in the length and three‐dimensional orientation of muscle fascicles and aponeuroses with passive length changes in human gastrocnemius muscles [PDF]

The Journal of Physiology, 2014
Key points The human gastrocnemius muscle is slack at its shortest lengths in vivo. We hypothesised that when the muscle is lengthened slack is taken up progressively, first in some muscle fascicles, then in others. A new, quasi‐three‐dimensional ultrasound imaging method was used to test this hypothesis directly.

Effect of isokinetic eccentric training on the human shoulder strength, flexibility, and muscle architecture in physically active men: A preliminary study.

PLoS ONE, 2023
Strengthening the rotator cuff muscles is important for injury prevention and rehabilitation. Since muscle fascicle length improves motor performance and is suggested to reduce the risk of injury for the hamstring, it may be an important variable to ...

In vivo assessment of muscle fascicle length by extended field-of-view ultrasonography

Journal of Applied Physiology, 2010
The present study examined the reliability and validity of in vivo vastus lateralis (VL) fascicle length ( Lf) assessment by extended field-of-view ultrasonography (EFOV US). Intraexperimenter and intersession reliability of EFOV US were tested. Further, Lf measured from EFOV US images were compared to Lf measured from static US images (6-cm FOV ...
