大强度训练对散打运动员心血管ET、CGRP、ANP水平的影响

采用放射免疫方法测定9名优秀散打运动员安静时血浆心血管激素,即内皮素(endothelin,ET),降钙素基因相关肽(calcitoningenerelatedpeptide,CGRP)和心钠素(atrialnatriureticpeptide,ANP)水平。经3个月的大强度训练,血浆ET水平逐渐升高,到最后两次取样时的变化明显,提示血浆儿茶酚胺、血管紧张肽分泌增加和(或)骨骼肌和心肌损伤可导致该激素水平提高;自训练开始,血浆CGRP水平依次降低,随着训练的深入其变化明显,表明长时期训练的效果异于急性运动;在大强度训练的进程中ET/CGRP比值逐渐升高,说明运动造成两种激素分泌不匹配;血浆ANP随着训练的深入逐渐升高,并最后两次取样变化明显,说明该激素对训练比较敏感;另外ET和CGRP、CGRP和ANP变化之间有明显的负相关,ET和ANP之间存在明显的正相关;研究显示血液指标的变化与血液浓缩无关。

Effect of High Intensity Training on Resting Cardiovascular Hormones of Elite Wushu Sanda Athletes

This work had used radioimmunoassay to determine 9 male elite Wushu Sanda (a self-defense oriented Chinese wushu) athletes' peaceful level of cardiovascular hormones, include endothelin(ET), calcitonin gene related peptide(CGRP) and atrial natriuretic peptide(ANP). During and after 3 months of high intensity training, the level of ET increased gradually towards the end it significantly increased by two points of measurement. The results suggest that increased plasma catecholamine and hypertensin secretion and/or anoxic and damage of skeleton and cardiac muscle would have caused enhanced ET level; At the beginning of high intensity training CGRP level decreased gradually and parallel with the training the CGRP level significantly decreased. It suggested that the effect of long-term training was different from short-term exercise; parallel with the intensity training, ET/CGRP ratio was increased. It points to a mismatching of the secretion of ET and CGRP; the level of ANP increased gradually and towards the end by points of measurement it was significantly higher than pre-training. The results suggest that the effect of high intensity training on ANP was significant; Another result showed that there was a significant negative correlation between ET and CGRP, a significant negative correlation between CGRP and ANP, there was a significant positive correlation between ET and ANP; This work suggests that the changes of hormone were not related to blood concentration.
