Impact of a short-term, moderate intensity, lower volume circuit resistance training programme on metabolic risk factors in overweight/obese type 2 diabetics.

The purpose of this study was to evaluate the effects of an 8-week, low frequency, hospital-based resistance training programme on metabolic risk factors in type 2 diabetic patients. Participants were self-selected into either an 8-week resistance training programme or a control group. Anthropometric indices, fasting glucose, HbA1c, total cholesterol, HDL and LDL lipoproteins, triglycerides, fasting insulin, and insulin sensitivity were assessed at baseline and 8 weeks later. Six participants were recruited (age 53 ± 9 years; BMI 32 ± 3 kg·m(-2)), and a further six participants acted as controls (age 55 ± 9 years; BMI 31 ± 3 kg·m(-2)). After training, waist circumference and waist-to-hip ratio were significantly reduced, with no associated changes in the control group. Metabolic risk factors remained unchanged following training (P > 0.05). We concluded that an 8-week, low frequency, resistance training programme reduced abdominal fat content but had little impact on metabolic risk factor modification in type 2 diabetics.
