Blood Proteomics-Based Detection of Upregulated Lipid Metabolism and Immune Dysfunction in an Elite Adventure Athlete Trekking Across Antarctica
OBJECTIVES: Proteomics when combined with psychological, nutrition, and performance measures may serve as a useful monitoring system for immune dysfunction, training distress, and exercise-induced muscle damage and exhaustion in athletes. Global proteomics monitoring of an elite adventure athlete (a...
