Research on Changes on Blood Plasma ANP of Female Boxer during Training

Abstract

Objective: In order to prepare for the national competition, change on blood plasma ANP of female boxer in training period was tested. Methods: In six weeks preparing for the training period, test blood plasma ANP on Monday morning in the first, third, fifth, seventh weeks respectively. Results: The analysis revealed: (1) The basis ANP was in lower limit of normal values, with in-depth training, ANP increased gradually, and the levels were significant differences (P<0.01); (2) Subjects grouped according to athletic performance , there was positive correlation between plasma ANP concentration and years of specialized training on elite athletes, correlation coefficient was 0.82, but plasma ANP concentration was not relevant with years of specialized training in general athletes. Conclusions: The longer the training period, the more adaptable remodeling made in heart endocrine capacity, and the higher ANP concentration in resting state.
