Monitoring skeletal muscle oxygen saturation kinetics during graded exercise testing in NCAA division I female rowers

Frontiers in Physiology
PurposeThe purpose of this study was to analyze changes in skeletal muscle oxygen saturation (SmO2) kinetics during exercise in female rowers both acutely and longitudinally in relation to blood lactate (BLa). We also aimed to determine the agreement and

Analytical Challenges in Detecting New Psychoactive Substances in Anti‐Doping: A Proof‐of‐Concept Involving Pentedrone Metabolite

Drug Testing and Analysis, EarlyView.
The paper describes an investigation related to the pentedrone norephedrine metabolite. The athlete's sample was analyzed using ultra‐performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS). According to the literature, this metabolite may originate from pentedrone, α‐pyrrolidinopentiophenone (PVP), or N‐ethylpentedrone (NEP).

Detection of a Distinct Erythropoietin (EPO) Profile After Isoelectric Focusing in Patients With Familial Erythrocytosis

Drug Testing and Analysis, EarlyView.
A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It

Statistical Discrimination of Urinary Steroid Biomarkers in the Athlete Biological Passport: A Novel Approach to an Abnormal Steroid Profile Score (ASPS)

Drug Testing and Analysis, EarlyView.
The study developed a single Abnormal Steroid Profile Score (ASPS) to improve interpretation of the Athlete Biological Passport steroid module. Using Bayesian modelling and logistic regression, biomarker patterns from laboratory and doping control data successfully discriminated between doped and clean individuals, with improved classification ...

Social Comparison and Its Association With Disordered Eating Symptoms: A Systematic Review and Meta‐Analysis

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Social comparison has been widely implicated in the etiology and maintenance of body dissatisfaction and eating disorders. At the same time, however, the magnitude of this relationship remains unclear, with existing studies varying widely in methodology, measurement, and sample characteristics.
