In order to investigate the characteristics of the cardiovascular function of Judoists, heart volume (HV), PWC170 and ECG at rest were measured in 22 Judoists of the first class and 26 student-Judoists of university, who were devided into a heavy class (above 90kg of body weight) of the first class (FH) or student (SH) and a light class (under 90kg of body weight) of the first class (FL) or student (SL).
1) Heart volume of FH(n=5), FL(n=7), SH (n=7) and SL (n=17) were 1,118.9+215.5ml,877.7±111.6ml,866.1+123.0ml and 767.7±96.1ml, respectively.
2) Heart volume per weight of FH, FL, SH and SL were 10.8±1.1ml/kg,11.9±1.9ml/kg,8.7±1.2ml/kg and 10.1±1.5ml/kg, respectively.
3) PWC170 of FH, FL, SH and SL were 1,535.9±221.1kg. m/min,1,302.3±134.6kg. m/min,1,265.7±212.1kg. m/min and 1,239.6±227.5 kg. m/min, respectively.
4 Mean values of the R Rinterval in FL (n=11) and SL (n=18) showed a tendency of prolongation in comparison with those of FH(n=11) and SH (n=8). In all subjects (n=36), significant correlation between HV and P, P Q interval were noted by 0.400(p <0.05) and 0.394 (p <0.05), respectively.
