Different Load Of Exercise Training On The Impact And Significance Of Changes In Rat Plasma Vasoactive Peptide

The paper including two parts . We reviewed the advance of Adrenomedullin(ADM), calcitoningene-related peptide(CGRP), endothelin(ET), and relation between them in Part one. Part two is Experiment. Objective: To explore the effect of different load exercise training on endocrine function of circulatory system and the relationship between it and the free radical metabolism. Method: The content of the plasma Adrenomedullin(ADM), calcitoningene-related peptide(CGRP), endothelin(ET), MDA and the activity of serum SOD in rats were measured after 8 weeks swimming training with different loads. Result: (1) Body ability of oxidation-resistance can be improved by the long time middle intension's sports training and in this course the content of plasma E^ ADM were properly increased, the excretion of CGRP were properly decreased. (2) Body ability of oxidation-resistance can be weakened by the long time high intension's sports training, the content of plasma ET was obviously increased, and the content of ADM, CGRP were distinctly decreased. (3)the activity of SOD can be descended by acute exhausting exercise, and in the course the content of MDA, plasma ET and ADM were increased. The content of CGRP was obviously decreased. Conclusion: The long time middle intension's sports training can improve the ability of the body to eliminate free radical and it is positively relative with the excretion of ET and ADM, while it is vice-relative with CGRP; The long time high intension's sports training will reduce the ability of the body to clean up free radicals and it maybe relative with the turbulence of several vessel active peptide . It was concluded that the turbulence maybe one of reasons that lead to exercising high blood pressure and acute exhausting exercise will cause the turbulence of vessel active peptide.
