Published: 18 May 2021
.... Therefore, the purpose of the present study was to reveal the relationship between myonuclear number per unit muscle fibre length and MPS under basal and conditions of elevated MPS by high-intensity muscle contraction (HiMC) using an in vivo nascent protein labelling technique (SUnSET) in rodents. We found...

...Michael M. DuVall; Azim Jinha; Gudrun Schappacher-Tilp; Timothy R. Leonard; Walter Herzog ABSTRACT Since the 1950s, muscle contraction has been explained using a two-filament system in which actin and myosin exclusively dictate active force in muscle sarcomeres. Decades later, a third filament...

.... Recently, advances in laser diffraction, optical microendoscopy and ultrasonography have enabled in vivo investigations into the behaviour of human muscle fascicles and sarcomeres with varying joint angle and muscle contraction intensity. With these technologies it has become possible to identify...
