Supplementation of 150mg resveratrol 15 minutes after the workout (three times weekly HIIT training) over four weeks in lightly trained men appeared to interfere with improvements in VO~2~ max and genetic adaptations to exercise (assessed by impairments in the exercise-induced increase in PGC-1a, SIRT1, and SOD2) when assessed via a Wingate test.
