Abstract

AIM:

The aim of the present study was to investigate not only the effects of aerobic exercise on overall cardiovascular risk factors profile and oxidative stress in obese, type 2 diabetic patients, but to elucidate if those effects depended on the previously estimated Systematic Coronary Risk Evaluation (SCORE) risk.

SUBJECTS AND METHODS:

Changes in several well-established cardiovascular risk factors and oxidative stress-defense parameters were measured in a total of 30 previously sedentary, obese type 2 diabetic patients, including 16 low-risk (SCORE < 5%, aged 48.8 +/- 6.0 years, with a mean BMI of 33.28 +/- 2.94 kg/m2) and 14 high-risk (SCORE > or = 5%, aged 56.3 +/- 6.9 years, with a mean BMI of 31.40 +/- 1.13 kg/m2) patients, in regard to the SCORE model, during six months of regular aerobic exercise, performed under supervision.

RESULTS:

Significant improvement was observed in the majority of cardiovascular risk factors, including body mass index, waist circumference, blood pressure, glycaemia, glycated haemoglobin, median blood glucose and lipid profile parameters in both diabetic subgroups during the exercise programme. However, the benefits of exercise on the majority of examined parameters became more evident in the low-risk subgroup, compared to the high-risk subgroup from baseline to 3 months. Regular exercise markedly reduced oxidative stress in both subgroups as well, as demonstrated for glutathione, plasma malondialdehyde, sulphydryl groups and catalase.

CONCLUSION:

Regular aerobic exercise, performed under supervision, has many beneficial effects in improving overall cardiovascular risk factors profile and reducing oxidative stress in both low-risk and high-risk (according to SCORE model), previously sedentary and obese type 2 diabetic patients.
