# Alpha memo: Resveratrol–exercise interaction in aged men may be variable rather than uniformly adverse; **One-sentence alpha:** The blunting of exercise training effects by 250 mg/day resveratrol in healthy aged men appears, on close reading, to be limited to a small subset of measured variables and is not a broad adverse effect. **Receipt 1:** *Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men* (Gliemann et al., 2013) — in 27 healthy inactive men aged ~65, 8 weeks of high-intensity exercise training plus 250 mg/day trans-resveratrol vs. placebo resulted in resveratrol blunting the exercise-induced increases in MAP and maximal oxygen uptake observed in the placebo arm. **Receipt 2:** *Recent data do not provide evidence that resveratrol causes 'mainly negative' or 'adverse' effects on exercise training in humans* (Gliemann et al., 2013) — a re-analysis of the same study notes that of ~45 variables examined, exercise training significantly improved 12 variables and failed to show resveratrol as a generally counteracting or harmful agent across that panel. **Why this is surprising:** Receipt 1's headline language of "adverse effects" implies a wide-ranging negative interaction, while Receipt 2 indicates the blunting is concentrated on a narrow set of endpoints within a largely favorable exercise response panel. **Caveats/falsifiers:** Population is limited to healthy older men (~65 y) at a single 250 mg/day dose over 8 weeks, with no women, no younger or clinical CVD cohorts, and no dose–response tested; a decisive falsifier would be an independent RCT in the same demographic using an equivalent or higher trans-resveratrol dose that demonstrates attenuation of multiple distinct cardiovascular endpoints, not just MAP and VO₂max.
