Data are presented as the mean ± SD. CONT: control (no exercise); MICT: moderate-intensity continuous training; HIIT: high-intensity interval training; g: gram; FM (%): percentage of fat mass; FFM: fat-free mass; W0: week 0; W5: week 5; W10: week 10. ∗HIIT vs. CONT: group effect (p < 0.05); †MICT vs. CONT: group×time interaction at W5 (p < 0.05); §HIIT vs. CONT: group×time interaction at W5 (p < 0.05); £HIIT vs. CONT: group×time interaction at W10 (p < 0.05); #HIIT vs. MICT: group×time interaction at W10 (p < 0.05). These data are included in another article dedicated to the effects of HIIT and MICT on gut-adipose tissue cross-talk in obese Zucker rats [34].
