Test-retest reliability of gastrocnemius medialis fascicle force-length relationship
Journal of BiomechanicsFascicle force-length relationship is one major basic mechanical property of skeletal muscle, subsequently influencing movement mechanics. While force-length properties are increasingly described through ultrafast ultrasound imaging, their test-retest reliability remains unknown.

Mechanics of feline soleus: I. Effect of fascicle length and velocity on force output
Journal of Muscle Research and Cell Motility, 1996The aim of the present study was to quantify how fascicle length and velocity modify force production in cat soleus. A computerized muscle puller controlled the length and velocity of the whole-muscle. We recorded the force output at the tendon and the length of muscle fascicles using sonomicrometry during whole-muscle isometric and isokinetic ...

IEEE Transactions on Biomedical Engineering, 2015
The fascicle length obtained by ultrasound imaging is one of the crucial muscle architecture parameters for understanding the contraction mechanics and pathological conditions of muscles. However, the lack of a reliable automatic measurement method restricts the application of the fascicle length for the analysis of the muscle function, as frame-by ...

Osteological Correlates of Fascicle Length and Gape in Carnivora
The FASEB Journal, 2022Previously, our lab has studied the scaling and dietary correlates of masticatory muscle fiber architecture separately in felids, musteloids, canids, and ursids as well as across the carnivoran order as a whole. In some of these lineages, fascicle lengths (FLs; a correlate of gape) scale with relative diet size, while across the ...

Measurement of Skeletal Muscle Fascicle Length
2021Muscle fascicle length (FL) is also an important quantitative indicator of skeletal muscle dynamics, and its changes directly reflect muscle activity. The calculation methods for muscle fiber length include the use of extended field-of-view ultrasonography (EFOV US) technology and optical flow tracking methods, etc.

Gastrocnemius Fascicle Length Changes with Two-Joint Passive Movements
Journal of Applied Biomechanics, 2008Predicting muscle fascicle length changes during passive movements may lead to a better understanding of muscle function. The purpose of this study was to experimentally compare fascicle length changes in the gastrocnemius during two-joint passive movements with a previously derived kinematic model based on anatomical measures from a cadaver. The ratio

Determination of fascicle length and pennation in a contracting human muscle in vivo
Journal of Applied Physiology, 1997Fukunaga, Tetsuo, Yoshiho Ichinose, Masamitsu Ito, Yasuo Kawakami, and Senshi Fukashiro. Determination of fascicle length and pennation in a contracting human muscle in vivo. J. Appl. Physiol. 82(1): 354–358, 1997.—We have developed a technique to determine fascicle length in human vastus lateralis muscle in vivo by using ultrasonography.

APONEUROSIS LENGTH AND FASCICLE INSERTION ANGLES OF THE BICEPS BRACHII
Journal of Mechanics in Medicine and Biology, 2002Magnetic resonance images and ultrasound images were used to examine the architecture of the distal biceps brachii muscle in 12 unimpaired subjects. The distal biceps brachii tendon continued as an internal aponeurosis that spanned 34± 4% of the length of the biceps brachii long head muscle on average. The distal muscle fascicles inserted at angles to

Fascicle length of leg muscles is greater in sprinters than distance runners
Medicine & Science in Sports & Exercise, 2000The purpose of this study was to compare architectural characteristics of leg muscles of sprinters and distance runners.Skeletal muscle architectural characteristics were studied in 23 elite male 100-m sprinters (SPR, 10.0-10.9 s for 100 m), 24 elite male distance runners (DR, 13.5-14.5 min for 5000 m), and 24 untrained male controls.

Estimation of cat medial gastrocnemius fascicle lengths during dynamic contractions
Journal of Biomechanics, 2002In typical muscle models, it is often assumed that the contractile element (fascicle) length depends exclusively on the instantaneous muscle-tendon length and the instantaneous muscle force. In order to test whether the instantaneous fascicle length during dynamic contractions can be predicted from muscle-tendon length and force, fascicle lengths ...
