The purpose of this study was to examine the impact of regular exercise on the change of lipids. Three groups were organized, which included a control group, a walking group and a jogging group. The latter two groups were asked to get no extra exercise. By type of exercise, the experimental group was divided into two subgroups: walking and jogging. The mean heart rate per minute was maintained at 40%HRmax(±5%) in the walking group and at 70°%HRmax(±5%) in the jogging group. Both groups walked or run separately for 30 minutes at a regular pace. The pretest was conducted before the experiment, and posttest was implemented twice, 8 and 12 weeks after the experiment. The lipids was measured while they were relaxed. The variables to be observed were total-cholesterol, triglyceride, HDL-C and LDL-C. As a result of analyzing the collected data, the following findings were given: 1. There was no significant lipids change when they were at ease after getting incremental loading exercise. So the incremental loading exercise didn`t affect lipids change during relaxation. 2. The two types of incremental loading exercise brought a different change, to lipids 8 weeks after the groups started exercising. Especially, the jogging group showed most increase or decrease, which showed jogging, one of high-intensive exercises, was more effective. 3. Exercise 12 weeks after, it`s found that not only type of exercise but exercise term made a difference to lipids change. In both walking and jogging groups, lipids change was more significant after 12-week exercise than 8-week one. This fact suggested that higher-intensive (jogging) and longer-term(12 weeks) regular exercise was more effective. 4. The control group showed no significant difference in lipids change after getting incremental loading exercise during different terms. Therefore, it could be said that incremental loading exercise didn`t have any influence, unless it`s done on a regular basis. 5. The lipids change of the walking group was more significant after 8- and 12-week exercise than at ease, except HDL-C. This implied HDL-C could increase after walking exercise for more than 8 weeks at least. So a regular exercise with an intensity equivalent to or higher than that of walking would produce a good result. 6. For the jogging group, HDL-C also increased more significantly after 12-week exercise than after 8-week one. As a regular exercise for 12 weeks or more exerted a significant impact on lipids change, a high-intensive and long-term exercise turned out more effective. In the jogging group, there was a significant lipids decrease among pretest, 8-week after posttest, and 12-week after posttest. And there also was a significant lipids decrease, except HDL-C, between 8-week exercise and 12-week one. Accordingly, a regular exercise for 8 weeks or more at least could serve to reduce cholesterol.
