Data are presented as mean ± SD, n = 24. MVC, maximal voluntary contraction; VO2max, maximal oxygen consumption; N+C, nitrate + citrulline, PLA, placebo; PRE, measure before the supplementation period; POST, measure after the supplementation period; ∆PRE/POST, difference between PRE and POST measures; p∆, p value for ∆PRE/POST group comparison; d∆, Cohen’s d effect size of N+C supplementation on ∆PRE/POST.
