This study investigates how increased tendon compliance affects muscle spindle firing during different stretch types and finds that firing rates are generally reduced but not fully explained by fascicle length and velocity.

The paper examines how lower-limb joints compensate for destabilizing energy during walking by analyzing mechanical work changes in response to treadmill perturbations.

This paper develops a machine learning framework to track muscle fascicle length changes in real-time using B-mode ultrasound, achieving reliable results comparable to standard post-processing methods.

This study investigates how aging affects biochemical interactions between bone and muscle cells using a rat model, finding that co-culture promotes differentiation but does not alter age-related changes in IGF-1 or collagen expression.

This study shows that increasing ankle angle shortens soleus muscle fascicles and increases metabolic energy expenditure during cyclic contractions, independent of mechanical work or force rate.

This study analyzes joint mechanics and energetics during walking and running on different inclines to inform the design of lower-limb exoskeletons.

This study examines whether carbon fiber plates in shoe soles improve running economy by analyzing biomechanics and energy expenditure in athletes.

This study uses ultrasound imaging to show that exoskeleton stiffness affects soleus muscle dynamics and metabolic rate during walking, with optimal savings at 50 Nm rad-1.
