수영운동이 흰쥐의 MDA와 근육 LDH 활성도 및 Pyruvate 함량에 미치는 영향 = The Effect of Swimming Exercise on MDA, Muscle LDH Activity and Pyruvate Content in Rats

다국어 초록 (Multilingual Abstract)

The purpose of the present investigation was to evaluate the effects of swimming on response of lipid peroxidation and muscle enzymes activity of hyperlipidemia rats. Twenty-five male SD rats(6 weeks old) were randomly divided into control group and 4 swimming groups after hyperlipidemia induction for 4 weeks 1% cholesterol diet, and then swimming groups swam for 6 weeks(7days/week) divided into 35 min, unloaded swimming group, 30 min, loaded swimming group, 60 min, unloaded swimming group and 50 min. loaded swimming group by swimming duration and intensity. The loaded swimming group rats among swimming groups swam a lead weight equivalent to 5% of Lady weight attached to the base of the tail, Analytical items were MCA, muscle LDH enzymes activity and pyruvate content. All data were expressed as mean and standard deviation by using SPSS/PC+ program and to evaluate the differences between and inter groups, data were analyzed by one-way analysis of variance and Duncan multiple range test(α=.05) was performed to test the significant levels of differences between groups, The conclusions obtained from this study were as follows:
1. There was not significant between groups in malondialdehyde(MDA).
2. In muscle lactate dehydrogenase activity, 30 min, unloaded swimming group and 30 min, Loaded swimming group were significantly lower than control group and 60 min, unloaded swimming group(P＜.001).
3. In muscle pyruvate content, all swimming groups were significantly higher than control group(P＜.001).
