Abbreviations used: BMI, body mass index; RM, repetition maximum; HOMA-IR, Homeostatic model assessment of insulin resistance; IFG = impaired fasting glucose; IGT = impaired glucose tolerance; HRT = hormone replacement therapy.
SI conversion: To convert glucose to mmol/L, multiply by 0.0555; insulin to pmol/L, multiply by 6.945; C-peptide to nmol/L, multiply by 0.331.
