Anti-inflammatory Effects of Curcumin, Ginger and Piperine Supplementation in Ultra-trail Runners: a Double-blind Randomized Placebo-controlled Trial (ECUM-RUN)
8 luglio 2026 aggiornato da: Centre Hospitalier Universitaire de la Réunion
ECUM-RUN is a randomized, double-blind, placebo-controlled phase 3 trial evaluating whether a 30-day oral supplementation with curcumin, ginger, and piperine (9-5-1 formulation) reduces exercise-induced joint pain and inflammatory markers in 82 ultra-trail runners competing in the Diagonale des Fous (175 km).
The primary endpoint is the change in knee pain (VAS score) between end of supplementation and race finish, compared between intervention and placebo groups.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Comparatore placebo: Controllo
|
Capsule excipients are maltodextrin and hydroxypropylmethylcellulose (HPMC), allowing an identical-appearing placebo for double-blind conditions.
|
|
Sperimentale: 9-5-1
|
The investigational intervention is an oral food-supplement capsule combining curcumin, ginger, and piperine in a proprietary "9-5-1" ratio (curcuma extract : ginger extract : black pepper/piperine extract), administered as 4 capsules per day for 30 consecutive days prior to the race.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in Knee Pain Intensity from End of Supplementation to Race Finish (Visual Analog Scale)
Lasso di tempo: From Day 30 (T1, end of the 30-day supplementation period) to race finish or withdrawal (T2) - up to approximately 60 hours later, corresponding to the maximum allowed race duration.
|
Knee pain is self-assessed using a Visual Analog Scale (VAS, 0-10 cm) at the end of the 30-day supplementation period (T1, day before the race) and immediately at race finish or withdrawal (T2).
The primary outcome is the within-participant change in VAS score (T2 minus T1), compared between the curcumin-ginger-piperine (9-5-1) group and the placebo group.
|
From Day 30 (T1, end of the 30-day supplementation period) to race finish or withdrawal (T2) - up to approximately 60 hours later, corresponding to the maximum allowed race duration.

Kinetics of Joint Pain Across the Study Period (Ankles, Knees, Hips)
Lasso di tempo: (T0, before supplementation) to Day 2 post-race or post-withdrawal (T3)
|
Pain intensity at the ankles, knees, and hips is self-assessed using a Visual Analog Scale (VAS, 0-10 cm) at each of the four measurement time points.
Between-group differences (intervention vs. placebo) in the T2-T1 change are compared, and a mixed linear model is used to describe the overall pain trajectory from T0 to T3, accounting for repeated within-participant measures.
