| Research Abstract |
Intervention studies were carried out to test a combination effect of aerobic exercise training and n-3 polyunsaturated fatty acids (PUFA) intake on various physiological and biochemical parameters using human subjects. Fifty-four women college students were divided into trained and non-trained groups throughout 3 series of experiment followed by a week of baseline period and 3-4 weeks of PLTFA-intake and training intervention periods. Purified perilla oil or EPA tablet were used as PUFA sources. In the 3^<rd> series of experiment, student athletes were used as trained group while non athlete students were used in the other two series. After the intervention, plasma triglyceride and blood glucose levels were decreased while plasma lipid peroxide level was increased in association with PUFA-intake. In wined group, however, this increase was less compared to that of non-trained group, especially in the athlete group. Furthermore these effects appeared to be dependent on amount of PUFA-intake Aerobic capacity was enhanced after PUFA-intake in both of trained end non-trained groups, with higher and longer effect in the former. A decrease of vitamin C level was observed in plasma of subjects after the intervention with significantly higher extent in the trained groups. These results appear to indicate an effectiveness of combined habitual aerobic exercise and n-3-PUFA intake for risk reduction of chronic noncommunicable diseases without an association of enhanced harmful oxygen species, as far as appropriate antioxidant nutrients, especially vitamin C, were provided.
