A novel diffusion‐tensor
Physiological Reports, 2016 AbstractMusculoskeletal (dys‐)function relies for a large part on muscle architecture which can be obtained using Diffusion‐Tensor MRI (DT‐MRI) and fiber tractography. However, reconstructed tracts often continue along the tendon or aponeurosis when using conventional methods, thus overestimating fascicle lengths. In this study, we propose a new method

Intramuscular fibre conduction velocity and muscle fascicle length in human vastus lateralis
Applied Physiology, Nutrition, and Metabolism, 2019 Muscle fascicle length and muscle fibre conduction velocity (MFCV) are thought to be important parameters for power performance. It might be expected that faster muscle fibre conduction velocities would compensate for longer fascicle lengths to increase the speed of action potential propagation along the elongated fibres.

Muscle fascicle and series elastic element length changes along the length of the human gastrocnemius during walking and running [PDF]
Journal of Biomechanics, 2007 Ultrasound imaging has recently been used to distinguish the length changes of muscle fascicles from those of the whole muscle tendon complex during real life movements. The complicated three-dimensional architecture of pennate muscles can however cause heterogeneity in the length changes along the length of a muscle.

Architecture of lower leg muscles in children: Reference curves and potential mechanisms of growth. [PDF]
J AnatMuscle architecture (physiological cross‐sectional area, fascicle lengths and pennation angle) was measured from multimodal MRI scans of the lower legs of 197 children aged ≤15 years. We showed that lower leg muscle volumes (product of PCSA and fascicle length) increase primarily through increases in PCSA (transverse growth) rather than increases in ...

The force-length relation of the young adult human tibialis anterior [PDF]
PeerJ, 2023 Background Knowledge of the muscle’s lengths at which maximum active isometric force is attained is important for predicting forces during movement. However, there is limited information about the in vivo force-length properties of a human muscle that ...

Morphology-Mechanics Links of the Free Achilles Tendon Revealed by Three-Dimensional Magnetic Resonance Imaging and Ultrasound Texture Analysis. [PDF]
Scand J Med Sci SportsABSTRACT This study aimed to elucidate the relationship between morphological and mechanical characteristics of the free Achilles tendon (ATFree) in vivo. The morphological features were characterized in terms of overall dimensions (length and cross‐sectional area) and internal fascicular organization (longitudinal alignment and transverse structure ...
