Skeletal muscle mRNA expression of 9 genes (A–I) upstream of NF-κB activity selected a priori for targeted analysis. Gene expression was measured during postexercise (24–27 hours) and overnight (27–36 hours) periods, following 300 unilateral eccentric knee extensor contractions (time = 0 hours). Postexercise and prebed protein-polyphenol (PP; n = 9; black bars) or isocaloric maltodextrin placebo (PLA; n = 9; white bars) drinks were ingested for 6 days prior to, and 3 days following, eccentric contractions. All individual expression values are expressed as a fold-change from the contralateral control leg at the same timepoint, with log₂ transformation applied. Data are presented as means, with error bars representing standard error. Statistical analysis was performed with separate 2-factor analysis of variance. *Main effect of time; ^†difference between PLA and PP. One symbol, P < 0.05; 2 symbols, P < 0.01; 3 symbols, P < 0.001; four symbols, P < 0.0001.
