Obesity indices and haemodynamic response to exercise in obese diabetic hypertensive patients: Randomized controlled...

Obesity, diabetes and hypertension are major worldwide interconnected problems. The aim of this study was to investigate body mass index (BMI), waist circumference (WC), systolic and diastolic blood pressure (SBP and DPB) responses to circuit weight training (CWT) or aerobic exercise training (AET) in obese diabetic hypertensive patients (ODHP).

Fifty-nine ODHP were randomly assigned into CWT, AET and control groups. Either CWT or AET was performed thrice weekly for 12 weeks. Variables were evaluated pre-training (evaluation-1), after 3 months (evaluation-2) and 1 month post-training cessation (evaluation-3).

At evaluation-2, BMI, WC, SBP, DBP mean values and percentages of decrease were 31.56±1.48 (9.23%), 104±5.97 (6.2%), 141±2.2 (3.09%), 91.2±1.24 (2.98%) and 32.09±1.21 (7.11%), 107.66±3.92 (3.07%), 138.3±1.17 (4.79%), 88.05±1.05 (6.02%) for CWT and AET groups respectively (P<0.05). At evaluation-3, mean values and percentage of decrease in BMI, WC, SBP, DBP were 31.88±1.54 (8.29%), 105±5.28 (5.26), 142.6±2.21 (1.99%), 92.7±0.86 (1.38%) and 33.26±1.22 (3.72%), 109.1±4.15 (1.77%), 140.35±1.23 (3.38%), 89.5±0.61 (4.47%) for CWT and AET groups respectively (P<0.05). There were also significant differences in BMI, WC, SBP, and DBP between groups at evaluation-2 and 3 (P<0.05).

While CWT is the intervention of choice to control obesity indices, AET is still the best intervention to lower blood pressure in ODHP, for a more extended period of time.
