Many studies have examined the effect of caffeine on exercise performance, but findings have not always been consistent. The objective of this study was to determine whether variation in the CYP1A2 gene, which affects caffeine metabolism, modifies the ergogenic effects of caffeine in a 10-km cycling time trial.

Caffeine is a well-established ergogenic aid, demonstrated to enhance performance across a wide range of capacities through a variety of mechanisms. As such, it is frequently used by both athletes and...
The aim of this investigation was to analyze the influence of the genetic variations of the -163C>A polymorphism of the CYP1A2 gene on the ergogenic effects of caffeine in elite basketball players.
This study aimed at investigating the effect of carbohydrate (CHO), caffeine (CAF) and a guarana complex (GUAc) ingestion during a running exercise on cognitive performance, ratings of perceived exert...
The main purpose of this study was to investigate if the rs11091046 (A>C) polymorphism in AGTR2 gene is associated with athletic status in top-level athletes from Brazil. Since the AGTR2 gene is locat...
This study sought to establish perceptions of elite endurance athletes on the role and worth of altitude training. Elite British endurance runners were surveyed to identify the altitude and hypoxic tr...

The purpose of this study is to determine whether AZD1775 has any effect on the pharmacokinetics (PK) of three compounds (caffeine, omeprazole, and midazolam) that are probes for common dr...
The study investigated the effect of caffeine on physical performance in healthy citizens aged over 70 years following eight hours of abstinence from caffeine containing drinks and foods. ...
The aim of this project is to investigate the potential benefits of combining a new protein meat hydrolysates extract with a regular endurance training programme on (a) body composition (b...
The study of NUTRITION PROCESSES during EXERCISE and ATHLETIC PERFORMANCE as well as specific NUTRITIONAL REQUIREMENTS of ATHLETES and the relationship between NUTRITIONAL STATUS and NUTRITION DISORDERS in athletes.
A cytochrome P-450 monooxygenase that can be induced by polycyclic aromatic xenobiotics in the liver of human and several animal species. This enzyme is of significant clinical interest due to the large number of drug interactions associated with its induction and its metabolism of THEOPHYLLINE. Caffeine is considered to be a model substrate for this enzyme. CYP1A2 activity can also be increased by environmental factors such as cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole.
A performance test based on forced MOTOR ACTIVITY on a rotating rod, usually by a rodent. Parameters include the riding time (seconds) or endurance. Test is used to evaluate balance and coordination of the subjects, particular in experimental animal models for neurological disorders and drug effects.
