# Alpha memo: resveratrol endurance exercise cross-context evidence signal
**One-sentence alpha:** Mouse evidence suggests resveratrol and exercise improve endurance in aged muscle, but human eccentric-exercise supplementation suggests that the same anchor does not cleanly carry over to acute inflammatory recovery.
**Receipt 1:** Effects of 14 days of prophylactic resveratrol supplementation in trained endurance runners upon the inflammatory markers TNF-a, IL1β, and IL-6 following a single bout of eccentric exercise — in eight trained male distance runners aged 35–45, the abstract frames the study purpose as evaluating whether 14-day 1000 mg trans-resveratrol affects TNF-α, IL-1β, and IL-6 after a single eccentric bout, reporting on these inflammatory markers without claiming a clear anti-inflammatory benefit in the supplied text.
**Receipt 2:** Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function — 18-month-old aged mice receiving 15 mg/kg/day resveratrol and/or 4 weeks of exercise training showed significantly longer time to exhaustion with decreased blood lactate and free fatty acids, decreased gastrocnemius lipid peroxidation, and increased catalase and superoxide dismutase activity versus aged controls.
**Why this is surprising:** Receipt 2 made it plausible that resveratrol plus exercise would translate as a positive oxidative-stress and endurance signal, and Receipt 1 updates that expectation by showing the same anchor in trained humans is being tested for inflammatory recovery with no clean carry-over evident in the supplied abstract.
**Caveats/falsifiers:**
- The two receipts differ on species (aged mice vs trained male distance runners, small n=8), dose (15 mg/kg/day vs 1000 mg/day), duration (4 weeks vs 14 days), modality (treadmill training vs eccentric bout), and endpoint family (oxidative-stress endurance markers in gastrocnemius vs circulating TNF-α/IL-1β/IL-6), so any moderator hypothesis such as species or context is tentative and confounded by these other axes; this should be read as a heterogeneous cross-context signal rather than a direct overturning, and no clinical, dosing, or supplementation recommendation follows from the two receipts.
- Receipt 1 reports on small-sample human inflammatory endpoints and does not establish equivalence with the mouse oxidative-stress findings, so a decisive falsifier would be a sufficiently powered human endurance-plus-recovery trial in trained or aged adults using dose-equivalent resveratrol with quantified inflammatory and oxidative endpoints showing whether the mouse signal carries over.
