QUESTION
In patients with type 2 diabetes, how do aerobic (AT), resistance (RT), and combined training compare for reducing haemoglobin (Hb) A1c concentrations?
METHODS
Design:
randomised controlled trial (Diabetes Aerobic and Resistance Exercise [DARE] trial).
Allocation:
concealed.
Blinding:
blinded ({data collectors}* and outcome assessors).
Follow-up period:
6 months.
Setting:
8 community-based exercise facilities in Canada.
Patients:
251 patients (mean age 54 y, 64% men) who had type 2 diabetes for >6 months, had baseline HbA1c concentrations of 6.6% to 9.9%, were previously inactive, and attended 10–12 exercise sessions during a 4-week run-in phase. Exclusion criteria included insulin use; ⩾20 min/session of exercise ⩾2 times/wk or RT in the past 6 months; changes in antihypertensive, lipid-lowering, or hypoglycaemic medication; …
