Values are reported as the mean ± standard deviation. Groups: SED, sedentary control; MICT, moderate-intensity continuous training; HIIT, high-intensity interval training. BW, body weight; Relative tissue weight (%) = tissue weight (g)/final body weight (g) × 100%.

^*P < 0.05,

^**P < 0.01. Means with different superscripts in each row are significantly different from SED (one-way ANOVA followed by Tukey's post-hoc test).
