Effect of Different Exercise Intensities on Cardiac Endocrine Function / 中国运动医学杂志

ABSTRACT

To study the effect of different exercise intensities on cardiac endocrine function, with radioimmunoassay, immunohistochemistry and the technique of computer image analysis, the level of plasma ANP and the expression of ANP in myocardial cells of rats with different training intensities were investigated. The result showed that with the increasing of exercise intensity,the level of ANP in plasma increased progressively, the expression of ANP in myocardial cells increased remarkably after moderate and heavy exercise training while it decreased remarkably after exhaustive exercise training. Results suggested that different exercise intensities revealed different effects on adaptation of cardiac endocrine function.
