# Alpha memo: resveratrol aged skeletal exercise promise outcome

Hypothesis-level alpha signal; not clinical advice.
## Core signal
A promise/outcome split is hiding in the receipt set. Receipt 10.1113/jphysiol.2013.270256 is framed as a promise: a randomized human trial in 60–72-year-old men designed to test resveratrol with exercise, reporting a null direction on the metabolic and inflammatory stress parameters studied (no exclusive resveratrol-mediated effect; resveratrol also blunted an exercise training-induced drop in protein carbonylation). Receipt 10.7717/peerj.7199 is the observed outcome: an animal mechanistic_model in 25-month-old male SD rats reporting positive direction on relative grip strength after resveratrol feeding versus Old controls, while gastrocnemius muscle index and absolute grip strength showed no significant differences across groups.

## The 2+2=5 angle
Reading the receipt titles verbatim, the human title says "training, but not resveratrol, improves"; the animal title says resveratrol feeding and exercise training both act on "skeletal muscle function." The non-obvious bridge is that "training" and "resveratrol" may move different endpoints in the same aged skeletal-muscle context, not the same endpoint in opposite directions. Receipt 10.1113/jphysiol.2012.230490 (replication, animal, positive on performance/stress) and 10.1007/s12576-017-0582-4 (mechanism, animal, framing resveratrol and exercise as targeting mitochondrial biogenesis) further suggest the divergence is endpoint-specific, not species-specific in the obvious way.

## Why this could matter
The split maps onto a boundary condition: human metabolic/inflammatory readouts (10.1113/jphysiol.2013.270256, null) versus animal functional/transcriptomic readouts (10.7717/peerj.7199, positive). Receipt 10.5717/jenb.2015.19.2.131 reinforces a "moderate exercise > resveratrol" framing on lipid metabolism in obese mice, adding a third layer where resveratrol shows no significant effect on the studied readout. So any "resveratrol replicates exercise" claim is hypothesized, not receipt-confirmed across endpoints.

## What would break the idea
A direct head-to-head human trial measuring both the metabolic/inflammatory panel from 10.1113/jphysiol.2013.270256 and a functional endpoint like relative grip strength, in the same aged cohort, would resolve whether the split is endpoint family or species.
