Abstract:
Objective To observe the effects of long-term Mulanquan exercise on antioxidative capacity and vasodilation.To elucidate the mechanism by which Mulanquan regulates endothelial endocrine function.To provide scientific evidence for Mulanquan's regulating blood pressure,improving cardiovascular function and preventing cardi- ovascular disease.Methods Forty-nine women volunteers were divided into an exercise group and a control group. They were fifty to sixty years old.The exercise group included 27 subjects who had practiced mulanquan regularly for at least two years.The control group comprised 22 subjects who had no habit of exercise.Their levels of serum ma- londialdehyde(MDA),superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),catalase(CAT)and nitric ox- ide(NO)were quantitatively determined.Results①Serum MDA was lower in the exercise group than in the con- trol group,and the difference between the two groups was highly significant statistically.Serum SOD activity and GSH-Px activity in the exercise group were higher than in the control group,the differences between the two groups being highly significant statistically.There was no significant difference between the groups in serum CAT activity. The serum NO content of the exercise group was higher than that of the controls,with the inter-group difference statis- tically significant.②Serum NO content was positively correlated with SOD activity ,GSH-Px activity,and SOD/MDA, and negatively correlated with MDA content.Conclusion Long-term Mulanquan exercise can suppress lipid peroxi- dation in middle aged and aged women.It can help maintain high antioxidative capacity,increase the secretion of NO,and thus limit any decrease in endothelium-dependent vasodilatation,which will be good for regulating blood pressure and preventing cardiovascular disease.
