A combination of aerobic exercise and resistance training can help diabetes sufferers, a new study has shown
think twice T
he number of adults with diabetes in the world has doubled since 1980, according to new research by Imperial
College London and Harvard University in the US, published in the Lancet. However, a new study by Canadian
researchers* offers a ray of hope, fi nding that glycaemic levels among patients with Type 2 diabetes can be improved by a workout programme that includes both aerobic exercise and resistance training. Typically, those who suffer from
diabetes are recommended sessions of aerobics to help treat their medical condition. However, the study – which was published in the Journal of the American Medical Association (JAMA) – suggests that adding strength training could result in greater benefi ts.
the study The randomised, controlled trial was based on 262 sedentary men and women in Louisiana, US. The average age of the group was 55.8 years old; 63 per cent of participants were female and 47.3 per cent were non-white. All participants had Type 2 diabetes,
and all took part in a nine-month exercise programme. The participants were split into four groups. Forty-one participants comprised the
non-exercise control group: they were offered weekly stretching and relaxation classes and were asked to continue with their typical physical activities. Seventy-three participants were
assigned to a resistance-only training group, where they exercised three days a week. Each session included two sets of four upper body exercises, three sets of leg exercises and one set each of abdominal crunches and back exercises.
Incorporating resistance training in a workout can help patients with Type 2 diabetes to improve their glycaemic levels
Seventy-two people took part in the
aerobic-only exercise group, where they expended 12 kcal/kg of bodyweight each week – around 150 minutes of moderate intensity physical activity a week. Then there was the combined aerobic
exercise and resistance training group, to which 76 people were assigned. Two resistance training sessions a week consisted of one set each of upper body, lower body, abdominal and back exercises. In terms of aerobic activity, they expended 10 kcal/kg bodyweight a week. All exercise sessions were
supervised and were designed to have approximately equal time requirements. Glycaemic levels were measured by
testing the amount of haemoglobin A1c (HbA1c
) in the blood.

7.7 per cent. Compared with the control group,
the HbA1c mean change in the combination exercise group was -0.34

per cent, while the mean changes in the resistance-only group at -0.16 per cent and the group that focused on aerobic training at -0.24 per cent were not considered to be statistically signifi cant. While all of the exercise groups
reduced their waist circumference, only the combination group improved their maximum oxygen consumption compared to the control group. In addition, while the resistance-
only training group lost an average of 1.4kg fat mass, the combination training group lost an average of 1.7kg fat mass compared with the control group. The report states that “only the
combination of the two [resistance and aerobic training] were associated with reductions in HbA1c levels.”
