Abstract:
The purpose of this study is to investagate the meaning of systolic time intervals (STI) in evaluating cardiac functional condition of athletes.1. STI and step test were examined on 13 sprinters, 8 jumpers, 5 throwers and 5 distance runners during early, middle and the last phases in summer training season.No significant changes of the left ventricular ejection time (LVET), the pre-ejection period (PEP) and PEP/LVET ratio were found from examinations on athletes in the three different phases.The cases were divided into two groups of PEP/LVET ratio increased more than 0.05 (N=8) and PEP/LVET ratio decreased more than 0.05 (N=10) by the different of PEP/LVET ratio between linked phases examinations. Athough two of PEP/LVET ratio of each group were different evidently (P
