A novel diffusion‐tensor MRI approach for skeletal muscle fascicle length measurements [PDF]
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

TTN genotype is associated with fascicle length and marathon running performance. [PDF]
Titin provides a molecular blueprint for muscle sarcomere assembly and sarcomere length can vary according to titin isoform expression. If variations in sarcomere length influence muscle fascicle length, this may provide an advantage for running ...

Curvature of gastrocnemius muscle fascicles as function of muscle–tendon complex length and contraction in humans [PDF]
It has been shown that muscle fascicle curvature increases with increasing contraction level and decreasing muscle–tendon complex length. The analyses were done with limited examination windows concerning contraction level, muscle–tendon complex length ...

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

Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number. [PDF]
Abstract Ultrasound-derived measurements of muscle fascicle length (FL) are often used to infer increases (chronic stretch or training) or decreases (muscle disuse or aging) in serial sarcomere number (SSN). Whether FL adaptations measured via ultrasound can truly approximate SSN adaptations has not been investigated.

Myofascial Loads Can Occur without Fascicle Length Changes. [PDF]
Many studies have shown that connective tissue linkages can transmit force between synergistic muscles and that such force transmission depends on the position of these muscles relative to each other and on properties of their intermuscular connective tissues.

The force-length relation of the young adult human tibialis anterior [PDF]
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 ...

Linking muscle architecture and function in vivo: conceptual or methodological limitations? [PDF]
Background Despite the clear theoretical link between sarcomere arrangement and force production, the relationship between muscle architecture and function remain ambiguous in vivo.
