What this trial studies
This study evaluates how caffeine intake influences participants' energy levels, motivation, and performance during physical training. Participants will engage in three sessions where they will consume caffeine, a placebo, or no substance, with their affective and motivational states assessed alongside their performance in a standardized exercise test. The study also aims to explore the impact of genetic factors on these responses, specifically focusing on gene polymorphisms that affect caffeine metabolism and sensitivity. Participants will be screened for eligibility based on their caffeine consumption and physical activity levels before being enrolled.
Who should consider this trial
Good fit: Ideal candidates are healthy individuals aged 18-30 who regularly consume caffeine and engage in physical activity.
Not a fit: Patients with cardiovascular, metabolic, gastrointestinal, or neurological diseases, or those who smoke or are pregnant, may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance understanding of how caffeine can be used to improve motivation and performance in physical training.
How similar studies have performed: Previous studies have shown varying effects of caffeine on performance and motivation, but this specific approach examining genetic variability is relatively novel.
