# Alpha memo: resveratrol exercise cross-context evidence signal
**One-sentence alpha:** Receipt 1 made plausible that resveratrol can attenuate acute-exercise IL-6/inflammatory signaling in rats, while Receipt 2 suggests that in aged men, resveratrol may blunt training-induced cardiovascular and metabolic gains, framing a context-dependent boundary rather than a uniform effect.

**Receipt 1:** The Impact of Resveratrol Supplementation on Inflammation Induced by Acute Exercise in Rats: Il6 Responses to Exercise. (2019; male Wistar rats, 12-week training at ~65% VO₂max with an acute bout at 70–75% VO₂max at 20 weeks; abstract was designed to evaluate trans-resveratrol on inflammation-related factors, consistent with a reduction in acute-exercise IL-6/inflammatory response per the title.)

**Receipt 2:** Resveratrol blunts the positive effects of exercise training in aged men; a double-blind, randomized, placebo-controlled training study (2013/2014, conference abstract supplement; 27 healthy inactive aged men, 65 ± 1 y, BMI ~25.4, 8 weeks of 250 mg/day resveratrol or placebo with high-intensity training 3×/wk; abstract reports training increased VO₂max and other adaptations, and the bundle entry states resveratrol blunted these training-induced positive effects.)

**Why this is surprising:** Receipt 1 supports a protective/anti-inflammatory role of resveratrol around acute exercise, so the aged-human signal that resveratrol may counteract rather than augment training adaptations is the unexpected direction worth flagging as a cross-context split.

**Caveats/falsifiers:**
- Receipt 1 is rat data with 12 weeks of training plus an acute bout at ~70–75% VO₂max; Receipt 2 is older (small-sample, n=27) human data at 250 mg/day for 8 weeks with high-intensity training — species, dose, duration, baseline age, and sample size all differ, so the moderator hypothesis is tentative and confounded by these axes; this is a heterogeneous cross-context signal, not a direct overturning, and no clinical, dosing, or supplementation recommendation follows.
- A decisive falsifier would be a human RCT in aged adults replicating Receipt 1's anti-inflammatory IL-6 trajectory and failing to blunt VO₂max/cardiovascular training gains, or a rodent protocol matching aged-human dose/duration that reproduces the blunting of training adaptations.
