TAAT Total abdominal adipose tissue, SAAT Subcutaneous abdominal adipose tissue, IAAT Intra-abdominal adipose tissue a. A P-value of < 0.05 was considered significant for the within group change
b. A P-value of < 0.025 was considered significant for the comparison of both intervention groups versus control. c. A P-value of < 0.05 was considered significant for the comparison exercise versus diet
