以大鼠为研究对象 ,建立持续训练、间歇训练、静力训练动物模型 ,研究了三种训练对大鼠循环系统内分泌的影响。结果显示 ,持训组血浆心钠素 (ANF)浓度升高 (P <0 0 1) ;间训组血浆心钠素浓度上升 (P <0 0 5 ) ,内皮素 (ET)浓度下降 (P <0 0 5 ) ;静力组心室肌血管紧张素Ⅱ (ANGⅡ )含量上升 (P <0 0 5 ) ;实验组血浆ANF、ET的相关系数均发生一定变化 (P >0 0 5 )。提示 :有氧训练对大鼠血浆ANF和ET的影响较为均衡 ;高强度无氧训练破坏血浆ANF、ET的平衡 ,动力性训练 (不论有氧还是无氧 )主要影响心房内分泌 ,表现在血浆中激素浓度的改变 ,静力性训练主要影响心室内分泌 ,表现在心室激素含量的改变。
The rat as the research object, to establish continuous training, intermittent training, static training animal model to study the three kinds of training on the endocrine system in rats. The results showed that plasma ANP concentration increased (P <0.01) in the training group, plasma atrial natriuretic peptide concentration increased (P <0 05) and endothelin (ET) concentration decreased <0.05). The content of angiotensin Ⅱ (ANGⅡ) in the ventricular myocardium increased in the static group (P <0.05). The correlation coefficients of ANF and ET in the experimental group all changed a little (P> 0.05). It is suggested that the aerobic exercise has a more balanced effect on plasma ANF and ET. High intensity anaerobic training destroys the balance of plasma ANF and ET, and dynamic exercise (whether aerobic or anaerobic) mainly affects atrial endocrine, manifested in plasma Changes in hormone concentrations, mainly affect the static training of ventricular endocrine, manifested in changes in ventricular hormone content.
