Chronic low back pain, as a common disease of aerobics athletes, has caused a lot of problems for aerobics athletes, and core strength training can form a strong back muscle through the back muscle training to maintain support functions. Maximize the physiological function of the spine to achieve the effect of treating chronic low back pain. To this end, this article raises the effect of core strength training on the chronic low back pain of aerobics athletes. This article uses electric traction as a control and conducts research by setting up a control experiment. Clinically, the ODI questionnaire is a commonly used judgment criterion for the diagnosis of lumbar function. This article uses the ODI questionnaire as the judgment criterion. The research in this article found that after the experiment, the subjects with a significant decrease in the ODI questionnaire scores in the two groups in the three surveys after treatment were over 80% of the total number in each group, indicating that core strength training is the same as traction therapy. In terms of the effect of treating chronic low back pain, it has obvious effects, and the method in this article is significantly better.
