# Alpha memo: resveratrol exercise combined-protocol attribution boundary

**Research question:** Does the combined-protocol skeletal/function signal in animal transfer to component-attributed skeletal/metabolic endpoints in aged-men?

**One-sentence alpha:** Receipt 1 reports a combined-protocol skeletal/function signal in animal that cannot be decomposed into single components; Receipt 2 tests component attribution in aged-men and bounds whether the shared anchor adds skeletal/metabolic benefit.

**Receipt 1:** Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function | 2017 | 10.1007/s12576-017-0582-4

**Receipt 2:** Exercise training, but not resveratrol, improves metabolic and inflammatory status in skeletal muscle of aged men | 2014 | 10.1113/jphysiol.2013.270256

**Synthesis:** Receipt 1 reports Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function; excerpt: Mitochondrial dysfunction and decreased mitochondrial content are hallmarks of aging that leads to decreased physical endurance. in an animal model. Receipt 2 reports Exercise training, but not resveratrol, improves metabolic and inflammatory status in skeletal muscle of aged men; excerpt: Exercise training increased skeletal muscle peroxisome proliferator-activated receptor-γ co-activator-1α mRNA ~1.5-fold, cytochrome c protein ~1.3-fold, cytochrome c oxidase I protein ~1.5-fold, citrate synthase activity ~1.3-fold, 3-hydrox 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: mice, aged, healthy, endurance, exercise, training, skeletal, function. Receipt 2 axes: men, aged, human, healthy, endurance, exercise, training, skeletal.
**Receipt-role check:** Receipt 1 is treated as the full combined protocol named in its title, not isolated single-component causality; it cannot attribute the signal to one component alone, and cannot support single-component efficacy in the other receipt's setting.
**Boundary scope:** The update crosses species/population, endpoint class, dose, duration, single-component attribution if a receipt tests a combined protocol at once, so the falsifier must match those axes before overturning the memo.
**Interpretation:** Receipt 1 establishes a non-decomposed combined-protocol skeletal/function signal in animal; Receipt 2 tests component attribution in aged-men on skeletal/metabolic endpoints; the update is attribution asymmetry across receipt-owned settings.

**Why this is surprising:** The surprise is not generic translation failure; it is the receipt-owned boundary between Receipt 1's intervention/model setting and Receipt 2's population and endpoints for resveratrol / exercise / training.

**Limitations:** This pair does not isolate which axis drives the split: species/population, endpoint class, dose, duration, single-component attribution if a receipt tests a combined protocol.

**Falsifier:** A matched aged-men study where the isolated shared component improves skeletal/metabolic endpoints versus placebo and adds benefit beyond the comparator arm would overturn the attribution-boundary 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.
