Skeletal muscle has the remarkable ability to remodel and adapt, such as the increase in
serial sarcomere number (SSN) or fascicle length (FL) observed after overstretching a …

During natural aging, skeletal muscle experiences impairments in mechanical performance
due, in part, to changes in muscle architecture and size, notably with a loss of muscle cross …

Maximal sprinting in humans requires the contribution of various muscle–tendon units
(MTUs) and joints to maximize performance. The plantar flexor MTU and ankle joint are of …

Background Despite the clear theoretical link between sarcomere arrangement and force
production, the relationship between muscle architecture and function remain ambiguous in …

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 …

Increased serial sarcomere number (SSN) has been observed in rats following downhill
running training due to the emphasis on active lengthening contractions; however, little is …

We evaluated the effects of differential muscle architectural adaptations on neuromuscular
fatigue resistance. Seven young males and six females participated in this study. Using a …

Introduction Brachial plexus birth injury (BPBI) and cerebral palsy (CP) both cause disabling
contractures for which no curative treatments exist, largely because contracture …

Objective The torque-producing capacity can be assessed as maximal isometric torque per
muscle size. Nevertheless, the factors contributing to this capacity remain poorly understood …

The purpose of this study was to characterize the short-term effects of Achilles tendon
ruptures on medial gastrocnemius. We hypothesized that the fascicles of the medial …
