ClinConnect Summary
This clinical trial is looking at how caffeine affects the body’s temperature control and exercise performance when running in hot weather. Specifically, it will study whether taking a moderate amount of caffeine changes how well trained runners can maintain their core body temperature and complete a 30-minute running test in 35°C (95°F) heat. Since exercising in the heat can be challenging and may lead to heat-related illnesses, understanding caffeine’s impact is important, as it is commonly used to boost performance but might affect how the body handles heat.
Men who are healthy and regularly train as runners may be eligible to take part in this study. Participants can expect to run for 30 minutes in a hot environment while researchers monitor their body temperature and performance. This study has not started recruiting yet, and it focuses only on male runners within a certain age range. If you are a trained male runner interested in how caffeine might affect your exercise in the heat, this trial could provide helpful information.
