Abstract
Background & objectives: The number of diabetes in India is increasing at an alarming rate. The effects
of physical activity in the form of resistance training or aerobic exercises on type 2 diabetes have not
been studied in Indian population. The objective of this study was to analyse the effects of eight weeks
of progressive resistance training (PRT) compared with aerobic exercise (AE) on glycaemic control,
metabolic profi le, cardiovascular fi tness parameters and general well being in adults with type 2
diabetes.
Methods: Thirty adults (14 females and 16 males mean; age 53.8 ± 8.8 yr) with type 2 diabetes were
randomly assigned to 8 wk supervised PRT (n=10) or AE (n=10) or control group (n=10). Glycosylated
haemoglobin (HbA1c), lipid profi le, blood pressure, heart rate, body mass index (BMI) and general well
being were measured before training (i.e. 0 wk) and after 8 wk of training period.
Results: Plasma glycosylated haemoglobin levels decreased signifi cantly : signififi (P<0.05) both in the PRT
group (7.57 ± 2.4% to 6.23 ± 0.8%) and in AE group (8.11±0.9% to 6.66 ± 0.9%).Total cholesterol levels
decreased signifififi cantly (P<0.05) by 13.3 per cent in PRT group and by 6.1 per cent in AE group. Both
exercise groups showed signifififi cantly reduction in systolic blood pressure (P<0.05). General well being
improvement was much more in PRT (8.6%) as compared to AE group (2.7%).
Interpretation & conclusions: Our fi ndings showed that both PRT and AE were effective in improving
metabolic profi le of adults with type 2 diabetes but the percentage improvement in triglycerides, total
cholesterol levels and general well being with PRT was more compared to AE. Further studies on a larger
sample need to be done to confirm these findings.
