Background:Based on sports physiology, sports biochemistry and sports training theory, in combination with long-term collecting research data and test results, the energy metabolism
characteristics of canoe slalom are analyzed. Combining with the characteristics of training and competition, it shows that the influence of environmental factors and high intensity anaerobic and
aerobic training are the foundation of this sport, anaerobic training especially lactic tolerance training is the key to success.
Methods:We made two runs of flat water 300 meters test and two runs of wild water special test, and altogether 6 runs of flat water 300 meters and wild water special test. Use the
Finnish Polar heart rate telemeter to record instant heart rate; use German EKF desk-top blood lactic acid instrument to record blood lactic acid (this research uses the average heart rate). Use EXCL,
SPSS for processing related physiological and biochemical data.
Results:(1)Using the heart rate and blood lactic acid to control training: The joint application of heart rate and blood lactic acid is currently the most widely used intensity
monitoring means in sports training. The two measures can check athletes’ reflection to the training intensity immediately after the exercises according to the time, so as to evaluate the main
metabolism of these exercises. Considering several full runs in canoe slalom, it is similar to the max lactic acid training type and lactic tolerant metabolic type in table 2, and the way of energy
metabolism of canoe slalom is mainly between the two. (2)Analysis of flat water 300 meters speed endurance test: Through the data acquisition and comprehensive analysis of 60 athletes from four
categories we can see that at present our athletes’ average heart rate does not reach 180 times/min, and the average blood lactic acid is between 11-13mmol/L. It shows that the intensity of the
training is not enough and there is still a gap compared with foreign athletes, illustrating our athletes are at a lower level on the speed endurance training.
Conclusions:（1）The development tendency is comprehensive development of excellent strength, speed, technology and sports intelligence. When developing sports intelligence, we should
also focus on the training of anaerobic speed endurance.（2）The change of training intensity correlates highly with the change of blood lactic acid density. Training level can affect the density of
blood lactic acid after exercise. The top athletes have good performance, at the same time their blood lactic acid density is high.（3）They should improve constant muscle work, maintain and improve the
ability of speed under high lactic tolerant ability in order to improve performance.
