Data are mean ± standard deviation for all participants. Only participants who complied with the intervention protocols and completed the intervention were included. SI conversion factors: to convert glucose values from mg/dL to mmol/L, multiply by 0.0555; to convert insulin values from μIU/mL to pmol/L, multiply by 6.945; to convert total, HDL, and LDL cholesterol values from mg/dL to mmol/L, multiply by 0.0259.
Abbreviations: BW, body weight; leg lean body mass, sum of lean body mass for right and left legs; SD, standard deviation.
Within a group, significant difference from baseline to month 12.
Between groups, significant difference at month 12.
