Abstract
Obesity and dyslipidemia are major risk factor of cardiovascular disease. It has been shown that dietary supplementation combined with exercise at appropriate intensity improve lipid profile and reduce the risk of cardiovascular disease. This study investigates the effect of purple sweet potato extract and swimming training on lipid profile of hyperlipidemic rat model. Twenty-five male Wistar rats were grouped into standard diet and high-fat diet, and given their respective diet for two weeks. Afterward, they were randomly divided into five weight-matched groups (n=5)- normal control (C), high-fat diet (HF), exercise (E), purple sweet potato extract (PSP), and exercise combined with purple sweet potato extract (EPSP). Purple sweet potato extract was given 100 mg/day through oral gavage for three weeks. Swimming exercise was performed for 30 minutes/day, five days a week, for three weeks. Bodyweight was measured weekly. At the end of experimental period, intracardiac blood samples were drawn to measure lipid profiles. The findings revealed that the concentration of TC and LDL were highest in HF. Combination of exercise and PSP extract significantly reduced LDL and increased HDL level in EPSP group compared to exercise or PSP alone (p<0,05). It indicates that PSP extract combined with swimming exercise is shown to be effective to improve lipid profiles.
