# Alpha memo: resveratrol exercise training signal

**Research question:** How far does the Receipt 1 signal transfer across the setting tested by Receipt 2?

**One-sentence alpha:** resveratrol / exercise does not carry one stable direction across the two receipts; the supported alpha is an endpoint- and setting-bounded comparison rather than a universal benefit or harm claim.

**Receipt 1:** Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men | 2013 | 10.1113/jphysiol.2013.258061

**Receipt 2:** Recent data do not provide evidence that resveratrol causes ‘mainly negative’ or ‘adverse’ effects on exercise training in humans | 2013 | 10.1113/jphysiol.2013.262956

**Synthesis:** Receipt 1 reports Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men; excerpt: Ageing is thought to be associated with decreased vascular function partly due to oxidative stress. in a human study. Receipt 2 reports Recent data do not provide evidence that resveratrol causes ‘mainly negative’ or ‘adverse’ effects on exercise training in humans; excerpt: The slightly blunted response to exercise in a few dependent variables is embellished in the running head, entitled ‘adverse effects of resveratrol on cardiovascular health’. in a human study. The comparison is bounded to resveratrol / exercise / training, and should not be read as advice, settled science, or a broad class claim.
**Bounded contrast:** Receipt 1 axes: men, aged, exercise, training, function. Receipt 2 axes: men, aged, human, exercise, training, function.
**Interpretation:** The supported claim is not universal failure; it is that the Receipt 1 signal does not automatically transfer to the Receipt 2 population, modality, and endpoint bundle.

**Why this is surprising:** The same named anchor is not enough. The useful signal is the boundary between the two receipt settings and endpoints, not a literature-average claim about resveratrol / exercise / training.

**Limitations:** This pair does not isolate whether species, population, dose, duration, modality, or endpoint class explains the split.

**Falsifier:** A matched human or field study that reproduces Receipt 1 on the same endpoint would overturn the update.

**Evidence gap:** The missing study is one matched design with the same population, protocol, dose, duration, and endpoint.

**Next test:** Run the same resveratrol / exercise / training comparison in one matched design before treating the signal as general.
