TTN genotype is associated with fascicle length and marathon running performance. [PDF]
Scandinavian Journal of Medicine & Science in Sports, 2017 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 ...

Ultrasonographic measurements of fascicle length overestimate adaptations in serial sarcomere number. [PDF]
Exp Physiol, 2023 AbstractUltrasound-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.

Improved Fascicle Length Estimates From Ultrasound Using a U-net-LSTM Framework. [PDF]
IEEE Int Conf Rehabil Robot, 2023 Brightness-mode (B-mode) ultrasound has been used to measure in vivo muscle dynamics for assistive devices. Estimation of fascicle length from B-mode images has now transitioned from time-consuming manual processes to automatic methods, but these methods fail to reach pixel-wise accuracy across extended locomotion.

Myofascial Loads Can Occur without Fascicle Length Changes. [PDF]
Integr Comp Biol, 2018 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.

Effect of plyometric training on the fascicle length of the gastrocnemius medialis muscle. [PDF]
J Phys Ther Sci, 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

A novel diffusion-tensor MRI approach for skeletal muscle fascicle length measurements. [PDF]
Physiol Rep, 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

Linking muscle architecture and function in vivo: conceptual or methodological limitations? [PDF]
PeerJ, 2023 Background Despite the clear theoretical link between sarcomere arrangement and force production, the relationship between muscle architecture and function remain ambiguous in vivo.
