title: Hypoxanthine: A Universal Metabolic Indicator of Training Status in Competitive Sports.
abstract: Cardiorespiratory and biochemical indicators typically used by contemporary elite athletes seem to have limited applicability. According to some recent studies, purine metabolism better reflects exercise response and muscle adaptation in this group. We propose using purine derivatives, especially plasma hypoxanthine concentration, as indicators of training status in consecutive training phases in highly trained athletes.
