Interplay between store‐operated calcium entry and mitochondrial phosphate handling modulates force and fatigue during exercise

The Journal of Physiology, EarlyView.
Abstract figure legend This study uses systems modelling to demonstrate a role of SOCE in sustained force generation during exercise. SOCE leads to two competing effects on contractile force in myofibres – increased cross‐bridge cycling due to elevated myoplasmic Ca2+$\text{Ca}^{2+}$ enhances force, whereas increased accumulation of myoplasmic ...

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Differential Quadriceps Muscle Activation Preoperatively and at the Time of Return to Sport After Medial Patellofemoral Ligament Reconstruction

Orthopaedic Journal of Sports Medicine
Background: Patients with patellofemoral instability (PFI) often demonstrate altered movement patterns and strength deficits. The vastus medialis plays an important role in patellar stabilization as a dynamic medial force vector on the patella ...

Macroscopic to ultrastructural analyses identify the loss of myofibrils as the primary mediator of ageing‐ and disuse‐induced muscle fibre atrophy

The Journal of Physiology, EarlyView.
Abstract figure legend Skeletal muscle structure was analysed at three levels in young vs. aged humans, and in young vs. aged mice subjected to unilateral hindlimb immobilization to model disuse. (1) Macroscopic: magnetic resonance imaging of the thigh (human) and wet mass of individual hindlimb muscles (mouse) revealed that both ageing and disuse ...

Immediate effect of anti-pronation foot taping on myoelectric activity of knee muscles in patellofemoral pain syndrome: a randomised controlled trial

Physiotherapy Quarterly
Introduction There is lack of studies on the effect of anti-pronation foot taping on the myoelectric activity of knee muscles. The purpose of this study was to investigate the immediate effect of anti-pronation foot taping on the myoelectric activity of ...
