초록

The aim of this study was to investigate the effect of 12-week aerobic exercise on total cholesterol (TC), blood pressure (BP), and cerebral blood flow (CBF) in obese middle aged woman. Twenty five women was finally selected as a subjects for this study because they have no medical problem for exercise and assigned to the control group (n = 13; age 39.21 ± 1.51 years; BMI 30.44 ± 1.13) and the exercise group (n = 12; age 38.78 ± 1.34 years; BMI 31.11 ± 1.45). Mean flow velocity (MFV) of CBF was obtained from the middle cerebral atrery (MCA) using Transcranial Doppler (TCD) and additional parameters like TCD index such as resistance index (RI) and pulsatility index (PI) was calculated from the Doppler wave form. Graded exercise test was performed with modified Bruce protocol using treadmill. Aerobic exercise program consists of 10 min warm-up, 40 min main exercise, and 10 min cool-down and subjects exercised for 60 min a day, 4times a week throughout 12 weeks with exercise intensity of %HRR 50 in 1 to 4 week, %HRR 60 in 5 to 8 week, and %HRR 70 in 9 to 12 week. Blood sample (5 ml) for total cholesterol was obtained from antecubital vein in all subjects. Statistical analysis was made using two-way repeated ANOVA followed by Sheffe's Post-hoc analysis and results are expressed as mean ± standard deviation (SD). Differences were considered significant for P < 0.05. The present results showed that 12-week aerobic exercise significantly decreased TC, BP, RI, and PI and increased MFV in the exercise group compared to the control group (P <0.05). These results suggested that 12-week aerobic exercise is effective for improvement of CBF by reducing BP and TC in obese middle aged woman.
