Effects of Caffeine on Elite Weightlifting Performance
Spain14 participantsStarted 2026-03-01
Plain-language summary
Weightlifting is a high-intensity strength-power sport where performance depends on maximal force, power output, and technical execution in the snatch and clean and jerk. Due to the sport's short-duration efforts, the ATP-PCr system predominates, with glycolysis supporting recovery between attempts. Given these demands, ergogenic aids are commonly used. While some supplements show limited or inconsistent evidence, caffeine stands out as one of the most well-supported for enhancing strength and power, mainly through central nervous system stimulation. Although its benefits are well documented in other strength sports, research specifically in Olympic weightlifting is scarce. Therefore, this study aimed to examine the effects of caffeine on neuromuscular and competition performance in elite weightlifters, hypothesizing a positive effect.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
