To the Editor: Dr Church and colleagues reported that among patients with type 2 diabetes, a group receiving a combination of aerobic and resistance training compared with a nonexercise control group had improved levels of hemoglobin A1c (HbA1c). This was not achieved by aerobic or resistance training alone.1 Prior research supports these results.2,3 For example, Cuff et al showed that adding resistance training to aerobic training resulted in enhanced glucose disposal, loss of abdominal subcutaneous and visceral adipose tissue, and increased muscle density in 28 obese postmenopausal women with type 2 diabetes.2 In the study by Church et al, more women (63%) were enrolled, and weight, body fat, and waist circumference reduction were observed in those receiving the combined training protocol.
