Introduction Chronic low back pain (CNLBP) manifests as chronic lumbosacral and hip pain, affecting athletes’ daily training and competition. Whole-body sports training can significantly improve the strength of the core muscles of the lumbosacral region and has certain advantages in the treatment of chronic low back pain. Object We study the therapeutic effect of whole-body physical training on athletes’ chronic low back pain (CNLBP). Method We selected 60 athletes with chronic low back pain patients. At the same time, we divide it into a control group and an observation group. The control group received conventional treatment, and the observation group received full-body physical training on this basis. After two months, the relevant physiological indicators of the patients were compared. Result After treatment, all physiological indexes of the two groups have great differences. Conclusion Whole-body physical training can significantly reduce athletes’ back pain symptoms and help restore professional athletes to regular training. Level of evidence II; Therapeutic studies - investigation of treatment results.
