摘要

The purpose of this study was to examine the effects of individual threshold on blood lactate and blood glucose after maximal sprint speed of 300 m. Methods: Subjects were athletics of sport university. Two kinds of tests in this study. One was increment intensity test, and another one was maximal sprint speed of 300 m. There were two tests one week apart in this study. All data showed by mean and standard deviation and Pearson's correlation coefficients. Results: The average maximal blood lactate of increment intensity test and maximal sprint speed different between 2.72 mmol/l (p ＜ 0.05). After exercise, no significant different was observed in blood glucose at 1st, 3rd and 10 minutes, but there were significant at 7 and 15 minutes. Anaerobic threshold and maximal blood lactate in maximal sprint speed 300 m showed a negative correlation (r = -0.6). Anaerobic glycolysis rate of maximal sprint and anaerobic threshold showed a negative correlation (r = -0.92). Aerobic threshold and heart rate after exercise 5 minutes showed a negative correlation (r = -0.5). Conclusion: Subjects have better anaerobic threshold, whose maximal blood lactate are lower and anaerobic glycolysis are better. Subjects has better aerobic threshold, whose heart rate recovery faster after exercise. This result showed that the threshold ability affect the symptoms of athletes anaerobic load. Therefore, we suggested that athletics want to decrease pressure of anaerobic load, and they must improve their anaerobic threshold.
