Effects of Daily Physical Activity on Serum Lipid Levels / 日本農村医学会雑誌

ABSTRACT

The effect of daily physical activity on the serum lipid level was examined. This study consisted of two parts, an epidemiological study and a laboratory study.<BR>In the epidemiological study, we investigated the relationship between serum lipids and energy expenditure in young adults females. Significant correlations were found between energy expenditure/body weight and the levels of serum HDL-cholesterol and serum triglyceride, and atherogenic index.<BR>In the laboratory study, we examined the effects of exercise on the serum lipid level. Groups of subjects took part in the programs of physical activity of two different intensities for 6 weeks, and their serum lipid levels before and after these programs were compared. Exercise regimens of increasing intensity caused a significant mean increase in the serum HDL-cholesterol level. However, these regimens did not cause any significant change in serum total cholesterol and serum triglyceride values.<BR>These results suggest that doing even light exercise on a regular basis is effective in producing an optimum serum lipid pattern in young adult females.
