Early and persisting increase in fat content after human muscle strain injuries in adults
Physiological Reports, Volume 14, Issue 17, September 2026.Abstract Acute muscle strain injuries belong to the most frequent sports injuries with high recurrence rates. Biopsies obtained from previously strain‐injured muscles showed fat intra‐ and intermuscular, but quantification of fat content in the entire muscle volume following a strain injury has not been performed previously. The aim of the study was to

Influences of Fascicle Length During Isometric Training on Improvement of Muscle Strength
This study investigated whether low-intensity isometric training would elicit a greater improvement in maximum voluntary contraction (MVC) at the same fascicle length, rather than the joint angle, adopted during training.

Automatic tracking of medial gastrocnemius fascicle length during human locomotion
Journal 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.

In vivo fascicle length measurements via B-mode ultrasound imaging with single vs dual transducer arrangements [PDF]
Journal of Biomechanics, 2017 Ultrasonography is a useful technique to study muscle contractions in vivo, however larger muscles like vastus lateralis may be difficult to visualise with smaller, commonly used transducers.

Muscle spindles in human tibialis anterior encode muscle fascicle length changes
Journal 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
Journal 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

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 ...

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