Sprint performance is related to muscle fascicle length in male 100-m sprinters
Journal of Applied Physiology, 2000The purpose of this study was to investigate the relationship between muscle fascicle length and sprint running performance in 37 male 100-m sprinters. The sample was divided into two performance groups by the personal-best 100-m time: 10.00–10.90 s (S10; n = 22) and 11.00–11.70 s (S11; n = 15).

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.

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

Forefoot running requires shorter gastrocnemius fascicle length than rearfoot running
Journal of Sports Sciences, 2019This study aimed to investigate the influence of foot strike patterns on the behaviour of the triceps surae muscle-tendon unit, including the Achilles tendon whose length nearly corresponds to force of the triceps surae, and the medial gastrocnemius muscle (MG) during running.

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.

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 ...

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.
