Caffeine Kinetics and CrossFit®-Specific Performance
Sponsor: Poznan University of Physical Education
Summary
The study aims at assessing the relation between caffeine (CAF) and paraxanthine (PAX) kinetics after acute ingestion of caffeine (3 mg/kg body mass) in the form or mono- or multi-ingredient preparations and CrossFit®-specific performance or selected indicators of psychophysiological state. Blood indicators of muscle damage/recovery, acid-base balance and electrolytes levels will be evaluated. The impact of genetic variations in the polymorphisms rs5751876 in ADORA2A gene and rs762551 in CYP1A2 on CAF/PAX kinetics will be considered.
