(2013), \"Resveratrol blunts the positive effects of exercise training on cardiovascular health in aged men,\" reports that 8 weeks of high-intensity exercise training with 250 mg/day trans-resveratrol in healthy inactive men aged ~65 led to exercise-induced improvements in several cardiovascular parameters that were smaller in the resveratrol group than placebo, with the authors' headline emphasizing blunting of training effects.\n**Receipt 2:** \"Recent data do not provide evidence that resveratrol causes 'mainly negative' or 'adverse' effects on exercise training in humans\" (same journal, 2013) reanalyzes Gliemann et al. and finds that of ~45 variables examined, exercise training improved 12 variables and did not worsen others, concluding the original framing as \"adverse\" is not supported by the data shown.\n**Why this is surprising:** The original paper's running head implies resveratrol counteracts exercise benefits, but the more granular re-examination suggests the blunting signal is narrow and may not generalize to a broader adverse-effect claim, meaning a single anchor (\"blunts\") can overstate the true effect direction.\n**Caveats/falsifiers:**\n- Both receipts concern the same small cohort (n≈27) of healthy inactive aged men on 250 mg/day trans-resveratrol for 8 weeks; effects at other doses, durations, sexes, or clinical populations remain untested.\n- A decisive falsifier would be a randomized trial in older adults showing either consistent blunting across multiple cardiovascular endpoints (refuting Receipt 2) or no blunting on any well-powered endpoint at comparable dose (refuting Receipt 1).\n","metadata":{"abstract":"Resveratrol may modestly reduce some exercise-induced
