What the study showed, in plain terms

Published in 2012, this source examined exercise and recovery. Design: Double-blind placebo-controlled crossover performance trial. Sample/model: 16 male soldiers. The exposure or intervention was Quercetin 1,000 mg/day in energy bars or placebo. Follow-up or treatment period: 8.5 days per condition.

Oxygen uptake, loaded-march responses, cycling time-trial performance, and perceived exertion did not improve.

Short male-only military study. Increased plasma quercetin did not produce measurable performance benefit under the tested schedule.

Key findings

  • Oxygen uptake, loaded-march responses, cycling time-trial performance, and perceived exertion did not improve.
  • The recorded outcome domains were Exercise performance or recovery.
  • The result applies to the tested exposure: Quercetin 1,000 mg/day in energy bars or placebo; 8.5 days per condition.

What this study can and cannot tell us

  • Short male-only military study. Increased plasma quercetin did not produce measurable performance benefit under the tested schedule.
  • An individual controlled trial must be interpreted alongside its comparator, sample size, endpoint selection and independent replication. It does not validate a different commercial formulation or a general longevity claim.
  • Source basis: Source check: PubMed abstract and indexed metadata; full methods were not independently confirmed for this entry. Missing method details, funding information or participant denominators are not inferred.
