Fascicle measurement methods do result in lengths that are significantly different

The Anatomical Record, EarlyView.
A recent comparison of the most prevalent methods for measuring fascicles, in situ measurement versus chemical digestion, concluded that the measurements are indistinguishable based on data from different conspecific individuals. However, our study of contralateral muscles of the same individuals shows that the methods clearly result in statistically ...

Rethinking the physiological cross-sectional area of skeletal muscle reveals the mechanical advantage of pennation

Royal Society Open Science
The shape of skeletal muscle varies remarkably—with important implications for locomotor performance. In many muscles, the fibres are arranged at an angle relative to the tendons’ line of action, termed the pennation angle.

Association between medial gastrocnemius muscle-tendon unit architecture and ankle dorsiflexion range of motion with and without consideration of slack angle.

PLoS ONE, 2021
Joint flexibility is theoretically considered to associate with muscle-tendon unit (MTU) architecture. However, this potential association has not been experimentally demonstrated in humans in vivo.

In Vivo Assessment of Shear Wave Propagation in Pennate Muscles Using an Automatic Ultrasound Probe Alignment System

IEEE Open Journal of Engineering in Medicine and Biology, 2023
Goal: Skeletal muscle mechanics can be assessed in vivo using shear wave elastography. However, the impact of pennation angle on shear wave velocity (SWV) remains unclear.

Postoperative Supraspinatus Muscle Volume Restoration Is Associated With Tendon Healing and Strength Recovery After Rotator Cuff Repair: Deep‐Learning‐Based Volumetric Analysis of the Entire Muscle With Clinical Correlation

Arthroscopy, EarlyView.
Purpose To quantify supraspinatus muscle volume (SPV) change after rotator cuff repair using deep‐learning‐based segmentation of full‐coverage magnetic resonance imaging and evaluate its associations with clinical, radiologic parameters, and retears. Methods This retrospective study analyzed rotator cuff repair patients with a minimum 2‐year follow‐up,

Nutrition and rehabilitation after anterior cruciate ligament reconstruction: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose As the impact of nutrition on rehabilitation and return to sport (RTS) after ACL reconstruction (ACLR) remains largely unexplored, this review aimed to review the current evidence on the role of nutrition in rehabilitation outcomes for ACLR patients, with as ultimate goal a safer and more successful RTS.

Muscle architecture of the medial gastrocnemius during growth

Journal of Physiological Anthropology
Background Muscle architecture is closely related to muscle function. Increased knowledge of growth changes in muscle architecture will provide insights into the development of human movements and sports performance during the growth period.

Regeneration of the semitendinosus tendon and muscle after isolated semitendinosus harvest for primary anterior cruciate ligament reconstruction: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To systematically evaluate the morphology, temporal evolution and musculoskeletal adaptations associated with semitendinosus tendon (ST) and muscle (SM) regeneration after isolated ST autograft harvest for primary anterior cruciate ligament reconstruction (ACLR).

Partial bodyweight-supported squats elicit eccentric contraction of the thigh muscles

BMC Musculoskeletal Disorders
Purpose The study aimed to investigate how different levels of supporting forces during the squat exercise at a self-selected speed, along with different knee angles, affect fascicle length, pennation angle, and muscle activation for healthy young ...
