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

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 ...

Vastus Lateralis Fascicle Length Changes During Stair Ascent and Descent
Journal of Orthopaedic & Sports Physical Therapy, 2008Experimental descriptive laboratory study.To describe the change in fascicle length of the human vastus lateralis (VL) muscle during the stance phase of stair ascent and descent.Muscle fascicle length changes during lower limb functional activities, such as walking and jumping, do not always coincide with joint angle changes.Thirty-three healthy ...

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 ...

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.

Biceps femoris fascicle length during passive stretching
Journal of Electromyography and Kinesiology, 2018The purpose of this study was to quantify the relative changes in fascicle (FL) and muscle-tendon unit (LMTU) length of the long head of the biceps femoris (BFlh) at different combinations of hip and knee joint positions. Fourteen participants performed passive knee extension trials from 0°, 45° and 90° of hip flexion.

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 ...

Muscle enlargement in sumo wrestlers includes increased muscle fascicle length
European Journal of Applied Physiology, 2000Skeletal muscle architecture was measured in 28 college sumo wrestlers (Sumo) and 30 control subjects. Pennation angle (PAN) and muscle thickness (MTH) of the triceps long head (TL), vastus lateralis (VL) and gastrocnemius medialis (MG) and lateralis (LG) muscles were measured by B-mode ultrasonography, and fascicle length (FAL) was estimated.

Gait & Posture, 2010
The purpose of the current study was to examine the reproducibility of fascicle length and pennation angle of gastrocnemius medialis while human walking. To the best of our knowledge, this is the first study of the reproducibility of fascicle length and pennation angle of gastrocnemius medialis in vivo during human gait.
