Abstract: Aiming at the problem that the athlete′s pulse wave information is used to determine the motion state(high intensity motion or calm)and reduce the randomness of the body condition to the pulse wave characteristic information， a method to construct the original pulse wave signal was presented. The method of training-test was used to classify the athletes′ heart rate to analyze the athletic state of the athletes and assist them in carrying out sports training work. Through the training of 10 athlete volunteers in different states， the original signal of the pretreatment was modeled and the physiological information was extracted. The SVM was used to supervise the training and test. The results show that the method can effectively discriminate the athlete′s heart rate state and get the state of motion.

Key words: pulse wave, function modeling, two categories, state discrimination
