Data are presented as mean ± SD, n = 24. SBP, systolic blood pressure; DBP, diastolic blood pressure; PWV, carotid-femoral pulse wave velocity; Reperfusion, difference between the value reached at the end of the ischemic phase and the maximal value reached during the reperfusion phase in the ischemia-reperfusion test; HbO2, oxyhaemoglobin; HbTot, total haemoglobin. PRE, measure before the supplementation period; POST, measure after the supplementation period. N+C, nitrate + citrulline, PLA, placebo; ∆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.
