# Alpha memo: resveratrol exercise training translation boundary
**One-sentence alpha:** Receipts suggest resveratrol can be a protective adjunct to high-intensity exercise in mice intestine yet may blunt cardiovascular training adaptations in aged men, hinting at a context-dependent split.

**Receipt 1:** "Resveratrol attenuated high intensity exercise training-induced inflammation and ferroptosis via Nrf2/FTH1/GPX4 pathway in intestine of mice" — in mice subjected to swimming plus 15 mg/kg/day resveratrol for 28 days, resveratrol reduced high-intensity-exercise-induced intestinal inflammatory factors and permeability damage.

**Receipt 2:** "Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men" — in 27 physically inactive men aged ~65 randomized to 250 mg/day trans-resveratrol or placebo with high-intensity training for 8 weeks, resveratrol abolished the training-induced rise in maximal oxygen uptake without changing MAP or training responses in other cardiovascular parameters.

**Why this is surprising:** The same resveratrol-plus-exercise anchor that suggested a protective signal in a murine intestinal model may, in older human cardiovascular endpoints, cancel one specific training gain (VO₂max).

**Caveats/falsifiers:**
- Receipt 1 is mice, intestine, Nrf2/FTH1/GPX4 pathway, 15 mg/kg/day, 28 days, while Receipt 2 is aged men, whole-body VO₂max, 250 mg/day, 8 weeks; species, endpoint family, dose, route, duration, and baseline status all differ, so the apparent "protection vs. blunting" split cannot be attributed to a single moderator.
- Decisive falsifier: a dose- and duration-matched human RCT testing resveratrol versus placebo on the same intestinal inflammatory and permeability endpoints after high-intensity exercise would test whether the murine protection translates; absence of effect on those endpoints would falsify the cross-context protection claim.
