Effects of Combined Rhodiola Rosea and Caffeine Supplementation on Dancesport Performance

China48 participantsStarted 2026-04-15

Plain-language summary

This study evaluates the effects of caffeine, Rhodiola rosea, and their combined supplementation on dancesport-specific performance in male collegiate dancesport athletes. Forty-eight healthy male athletes aged 18 to 23 years will be randomly assigned to one of four groups: placebo control, caffeine, Rhodiola rosea, or combined Rhodiola rosea plus caffeine. All participants will complete the same four-week standardized cowboy-dance-specific training program. The caffeine group will receive caffeine at 3 mg·kg-¹ before testing, the Rhodiola rosea group will receive Rhodiola rosea at 2.4 g·day-¹ for four weeks, and the combined group will receive both supplementation strategies. The main purpose of this study is to determine whether these supplementation strategies improve cowboy-dance-specific explosive power, movement stability, repeated kicking performance, agility, muscular endurance, and perceived exertion. Main outcomes include the 180-degree kick straight angle, kick recoil angle, trunk anterior-posterior sway amplitude, and 30-second cowboy-kick success rate. Secondary outcomes include qualified kick count, balance, core stability, functional strength, rhythm accuracy, agility tests, hexagon jump performance, and session-RPE.

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?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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?
