Skeletal Muscle Memory: An Update From the Antidoping Perspective

open access: yesDrug Testing and Analysis, EarlyView.
ABSTRACT This narrative review explores the concept of muscle memory, focusing on the physiological and biochemical mechanisms underlying information retention in skeletal muscle tissue as it relates to antidoping. The discussion encompasses the role of satellite cells (SCs) in myonuclei recruitment, resulting in increased myonuclear density and ...

β‐Hydroxy β‐Methyl Butyric Acid (HMB) and Its Potential Doping Relevance: A Pilot Study on Its Urinary Excretion Profile

open access: yesDrug Testing and Analysis, EarlyView.
β‐hydroxy β‐methyl butyric acid (HMB), either as the free acid or in the form of its calcium salt, is a component of several dietary supplements marketed to enhance sports performance. We investigated the urinary excretion profile of HMB, also assessing the endogenous reference ranges of HMB in human urine samples from healthy volunteers (n = 20). Data

Proteomic profiling of impaired excitation–contraction coupling and abnormal calcium handling in muscular dystrophy

open access: yesPROTEOMICS, Volume 22, Issue 23-24, December 2022., 2022
Abstract The X‐linked inherited neuromuscular disorder Duchenne muscular dystrophy is characterised by primary abnormalities in the membrane cytoskeletal component dystrophin. The almost complete absence of the Dp427‐M isoform of dystrophin in skeletal muscles renders contractile fibres more susceptible to progressive degeneration and a leaky ...
