How to use this page

This note summarizes one study record. Check the participants, methods, results, and limitations before applying it to training.

  • Design signal: controlled study.
  • Population relevance: mixed/unclear athlete specificity.
  • Consistency: single-study evidence.
  • Practical recommendation depends on tolerance, context, and whether it protects training consistency.

ELI5

In plain language

The adaptogen Rhodiola rosea (RR) may mitigate stress responses and have beneficial effects on endurance capacity (EC) and mental performance. (controlled study; n=10 participants).

The abstract doesn’t indicate a clear change in Performance in heat under the tested conditions. Treat this as a signal, not a guarantee; confirm methods and context in the full paper.

Takeaways

What the abstract suggests

  • Study question: The adaptogen Rhodiola rosea (RR) may mitigate stress responses and have beneficial effects on endurance capacity (EC) and mental performance.
  • The abstract doesn’t indicate a clear change in Performance in heat under the tested conditions.
  • Population: n=10 participants.
  • Protocol cues (title/abstract): 432 mg • 44.1 min • 59.8 min • 6 km.

Protocol

Protocol (as reported)

  • Intervention/exposure: heat acclimation (vs placebo).
  • Dose/time/duration cues in abstract/title: 432 mg • 44.1 min • 59.8 min • 6 km.
  • Outcomes: Performance in heat.
  • Replication note: abstracts often omit adherence and timing; confirm details before changing training or supplementation.

Fit

Who it may help, and who should be cautious

Who it helps

  • Athletes similar to the study population (n=10 participants) working on heat.
  • Athletes who can measure Performance in heat with a repeatable workout or time-trial effort.

Who should be cautious

  • If you have symptoms or conditions that make the intervention risky, get professional guidance.
  • If you’re near race day and can’t safely test, defer the experiment.

Methods

What the study actually did

  • Design: controlled study (placebo-controlled).
  • Population: n=10 participants.
  • Comparator: placebo.
  • Outcomes measured: Performance in heat.
  • Protocol cues mentioned: 432 mg • 44.1 min • 59.8 min • 6 km.
  • Source: PubMed PMID 28873320 (2018) — Applied physiology, nutrition, and metabolism = Physiologie appliquee, nutrition et metabolisme.

Results excerpt

What the abstract reports

However, the magnitude of all these changes was similar (p > 0.05) in the SHR and PLC groups.

Note: excerpts are short; for full context, read the paper.

Limits

Limitations and bias

  • Abstract-only summaries can miss critical details (population, protocol, adherence, and context).
  • Single studies often don’t generalize to your event, history, and training load; treat results as a starting point.
  • If your context differs (elite vs recreational; cycling vs running), adjust expectations and be conservative.
  • This is performance information, not medical advice.
