Strength training promotes a IIX-to-IIA shift in myosin heavy chain (MHC) composition, likely due to changes in sarcoplasmic [Ca2+ ] which are sensed by CaMKII. Sarcoplasmic [Ca2+ ] is in part regulated by sarcolipin (SLN) a small protein, that when overexpressed in rodents stimulates mitochondrial biogenesis and a fast-to-slow fibre type shift. Th...

Introduction: Repetition velocity can be used to prescribe the relative load (%1RM) due to its strong relationship (R2=0.98) in the bench press (BP) exercise (1) and in other exercises, (R2=0.96) as in full squat (2). However, one of the main drawbacks of these studies is that, to the best of our knowledge, the load-velocity relationship has been a...

Introduction: One emerging method to train athletes is to assign a specific lifting velocity rather than load. Using these methods, researchers have observed varying adaptations from assigning different levels of velocity-loss (ranging from 1040% of initial velocity) prior to terminating each set [1]. However, manifestations of neuromuscular fatigu...
