BW¹, body weight at the start of the training program (F_training = 0.0266, F_sex = 496.645, F_int = 0.783, df_training = 1, df_sex = 1, df_int = 1, P_training = 0.872, P_sex < 0.001, and P_int = 0.384); BW², body weight at the end of the training program (F_between groups = 180.443, df_between groups = 3, P_{between groups} < 0.001); HW heart weight (F_between groups = 45.132, df_between groups = 3, P_{between groups} < 0.001); HW/BW², heart weight/body weight ratio (F_between groups = 37.254, df_between groups = 3, P_{between groups} < 0.001)
One-way ANOVA (BW², HW, HW/BW²) and two-way (BW¹) ANOVA with post hoc Tukey’s test. Values are the means ± SEM. *P < 0.05 vs. male sedentary; ^#P < 0.05 vs. female sedentary; ^$P < 0.05 vs. male exercised
