The purpose of this paper is to study the temperature characteristics of acupoints in sports training adapted to wireless communication thermal imaging. As the development of sports tends to be mature, the amount of training for athletes has also increased, and it is for this reason that the physical load of athletes is getting heavier and heavier. Traditional Chinese medicine pays attention to the theory of acupoints, which is the inheritance of China’s historical experience. The method is to study the temperature characteristics of acupuncture points and the effect of sports on acupoints from the perspective of the symmetry of the temperature and the amount of exercise on the acupuncture points. Through the exploration of infrared thermal imaging technology, experimental simulations are performed on rabbits. The results showed that the average temperature at the acupoints of Neiguan and Xinshu was higher, and the average temperature at the acupuncture points was lower. The results of the experimental part show that the body temperature of the experimental subject after exercise is not significantly different from the body temperature before exercise. There are temperature changes in some acupuncture points, but the temperature difference does not change much.
