Effect of Regular Exercise on Low-Density Lipoprotein Level

Abstract

Low-density lipoprotein (LDL) is called bad cholesterol. High LDL level leads to a build-up of cholesterol in arteries, which may elicit heart disease. Therefore, it is necessary to keep under controlled LDL levels for the safety of life. The researchers in this study investigate whether exercise may lead to decreasing the LDL level. A total of sixty undergraduate willing female students, with a mean age (of 22+1 years), were conveniently selected from two populations and divided into two groups: the exercise group (n=30) and the wait-for-list control group (n=30). A total of four hours per day and six days per week of exercise and games were practiced for twelve weeks by the exercise group. The Hitachi 704 analyzer conducted a lipid profile test during pre and post-intervention. The level of LDL was decreased by 32.48% after twelve weeks in the exercise group. It can be explained that the physiological process of fat loss occurs when fats are liberated from adipocytes and other areas into circulation to supply the needed energy during exercise.
