Abstract

Physical inactivity is closely related to obesity. Besides being a risk factor for cardiovascular disease, certain cancers and type II diabetes, obesity has also been associated with dysregulation of autonomic function in human. Many studies suggest that exercise therapy can improve autonomic nervous system(ANS) modulation of Blood Pressure (BP) in healthy individuals. The aim of this study was to determine the effect of moderate aerobic exercise on cardiovascular function in obese. Fifty-two obese adults participated in this study. Anthropometric parameter were measured. Blood Pressure (BP) was measured in supine position and on immediate standing. For cold pressure test (CPT), resting BP was measured in sitting position and after 1 min of immersion of one hand in cold water. All the parameters were recorded before and after six months of supervised aerobic training given thrice-a-week. The difference (Δ) in systolic blood pressure(SBP), diastolic blood pressure(DBP) & Mean Arterial Pressure(MAP) during change in posture from supine to immediate standing was significantly increased after the exercise training (12.8±5.65,7.62±3.26,10.61±3.45 for ΔSBP,ΔDBP,ΔMAP respectively) as compared to before exercise. (10.05±4.46,7.38±3.52,8.78±2.1 for ΔSBP,ΔDBP, ΔMAP respectively). In CPT, ΔSBP was significantly(p=0.04) increased after exercise training(9.46±2.54) than before(6.94±3.86), while ΔDBP,ΔMAP (6.7±3.4, 6.2±4.6 respectively) were not affected (p=0.49,0.80 respectively) after exercise (6.16±3.27, 3.3±3.28 respectively). Our study suggests that thrice-a-week moderate intensity aerobic exercise for six months improves cardiac rhythm regulation as measured by change in BP while change posture from supine position to immediate standing and by CPT in obese adult.
