Table 1 Incremental exercise test performed before (initial) and after (final) 4-week sedentary (S) or exercise-trained (Ex) wild-type (WT) and LDL receptor knockout mice (LDLr−/−)

From: Aerobic exercise training protects against endothelial dysfunction by increasing nitric oxide and hydrogen peroxide production in LDL receptor-deficient mice

  1. Data are mean ± SEM. The number of animals per group was: WT S (n = 20); WT Ex (n = 20); LDLr−/− S (n = 20); LDLr−/− Ex (n = 20)
  2. Two-way ANOVA: * p < 0.05 vs. WT S; # p < 0.05 vs. LDLr−/− S
