# Alpha memo: resveratrol endurance exercise cross-context evidence signal
**One-sentence alpha:** Preclinical data in aged mice suggest resveratrol combined with exercise may counteract age-related endurance decline, while a small human prophylactic trial in trained runners suggests the same anchor may not translate cleanly to eccentric-exercise inflammatory outcomes.

**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* (2011) — In eight trained male distance runners (mean ~38 yr), 14 days of 1000 mg/day trans-resveratrol taken before a single eccentric exercise bout was tested against placebo for effects on TNF-a, IL-1b, and IL-6; the abstract frames resveratrol as having potential to attenuate these inflammatory markers, and reports the design but not a confirmed favorable shift in these endpoints.

**Receipt 2:** *Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function* (2018) — In 18-month-old aged mice, 4 weeks of RSVT (15 mg/kg/day) and/or exercise training produced longer time to exhaustion versus aged controls, with decreased blood lactate and free fatty acids and lower gastrocnemius lipid peroxidation plus higher catalase and superoxide dismutase activity.

**Why this is surprising:** Receipt 2 makes plausible a clean positive resveratrol-plus-exercise endurance signal in aged skeletal muscle, but Receipt 1 (a small n=8 trained-runner human trial at a very different dose and context) suggests the same anchor does not clearly extend to a prophylactic human eccentric-exercise inflammatory setting, a heterogeneous cross-context signal rather than a direct overturning.

**Caveats/falsifiers:**
- Cross-species, cross-dose, cross-modality, and cross-endpoint-family pair (aged mice endurance/oxidative endpoints vs trained adult men inflammatory markers after eccentric exercise), so the moderator hypothesis (age vs training status vs endpoint) is tentative and confounded by the other axes.
- No clinical, dosing, or supplementation recommendation follows from these two receipts; sample sizes are small (n=8 runners; n unspecified per arm in mice), and the 2011 human paper is a small pilot/design-framed report, so a decisive falsifier would be a larger, adequately powered randomized human trial in aged or trained adults measuring both endurance performance and eccentric-exercise inflammatory markers at dose-escalation regimens.
