# Alpha memo: resveratrol exercise training aged cross-context evidence signal

**One-sentence alpha:** Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function made us expect resveratrol would travel cleanly as a positive signal; Exercise training, but not resveratrol, improves metabolic and inflammatory status in skeletal muscle of aged men forces the update that the same anchor can fail, reverse, or split by context.

**Receipt 1:** Resveratrol and/or exercise training counteract aging-associated decline of physical endurance in aged mice; targeting mitochondrial biogenesis and function | 2018 | 10.1007/s12576-017-0582-4 | finding: Mitochondrial dysfunction and decreased mitochondrial content are hallmarks of aging that leads to decreased physical endurance. Our aim was to explore the anti-aging effect of resveratrol (RSVT) supplementation, a polyphenol, and/or exercise training, started at an older age, on improving physical activity, therefore, help in frailty avoidance and promotion of healthy aging in elderly. Eighteen-month-old aged mice received RSVT (15 mg/kg/day) and/or exercise trained for 4 weeks showed significant longer time to exhaustion with decreased blood lactate and free fatty acids levels associated with improved oxidative stress evidenced by decreased gastrocnemius muscle lipid peroxidation and incre

**Receipt 2:** Exercise training, but not resveratrol, improves metabolic and inflammatory status in skeletal muscle of aged men | 2014 | 10.1113/jphysiol.2013.270256 | finding: The aim was to investigate the metabolic and anti-inflammatory effects of resveratrol alone and when combined with exercise training in skeletal muscle of aged human subjects. Healthy, physically inactive men (60-72 years old) were randomized to either 8 weeks of daily intake of 250 mg resveratrol or placebo or to 8 weeks of high-intensity exercise training with 250 mg resveratrol or placebo. Before and after the interventions, resting blood samples and muscle biopsies were obtained and a one-legged knee-extensor endurance exercise test was performed. Exercise training increased skeletal muscle peroxisome proliferator-activated receptor-γ co-activator-1α mRNA ~1.5-fold, cytochrome c protein 

**Why this is surprising:** The pair has `mechanism_to_human_failure` geometry over `resveratrol, exercise, training` rather than a broad literature-summary bridge.

**Caveats/falsifiers:**
- Reject if the shared anchor is not the same construct/intervention in the full text.
- Reject if later receipts show the apparent reversal is only population, dose, or measurement noise.
- Reject if either receipt is a review, case-only report, or keyword-only match.
