The purpose of this study was to investigate the physiological response and exercise performance of senior high school elite judo players. Subjects were thirty-eight senior high school elite judo players (age: 16.6±0.9 yrs, height: 174.5±7.0 cm, weight: 81.5±24.6kg, training experience: 4.6±2.2 yrs). All subjects had performed two different tests voluntarily. First, judo professional endurance test, Uchi-Komi & Seoi-Nage skill tests were performed for 4 sets when the subjects reached maximal efforts. The duration was set for 10 seconds and each interval was 30 seconds according to Lehmann's method, the blood samples were collected at 1st, 3rd and 5th minutes(E-1, E-3, E-5) after endurance test. Second, incremental intensity test was performed in the Athletics Field, started at 2.5m/s, increased 0.5m/s for each sets, and the duration was 5 minutes. This incremental intensity test was terminated until volunteers all out. Blood sample and heart rate had been recorded during the interval rest. One way ANOVA was the statistic method to analysis the blood lactate variance during judo professional skill test, the significant level was α=.05. The results were shown that the senior high school judo male players had poor endurance ability (aerobic speed threshold: 2.2±0.4m/s, anaerobic speed threshold: 3.0±0.3m/s). Further more, the blood lactate samples during professional skill test were insignificant (E-1was 4.2±1.3mmol/l, E-3 was 4.5±1.6mmol/l and E-5 was 4.4V1.6mmol/l, p>.05). The maximal blood lactate volume was at 3rd minute after test and the average blood lactate metabolic rate was 0.3±0.2mmol/l, this result indicated that the lactate metabolic rate was too slow to influence performance. Subjects with higher maximal blood lactate volume had better performance in professional skill test, in opposite; subjects had poor performance that had lower maximal blood lactate volume. And even, it had shown the subjects had higher anaerobic glycolysis and better speed endurance ability if they reach higher power and peak blood lactate volume. In conclusion, we suggested that the four dimensions constructed by blood metabolic rate and judo professional skill test could be used to evaluate the judo professional skills.
