Prolonged sitting often leads to lumbar muscle fatigue, increased intervertebral disc pressure, and decreased core strength, subsequently resulting in lumbar disc herniation. With the continuous rise in sedentary behavior in modern society, lower back pain has become increasingly prevalent, significantly impacting individuals’ quality of life. In recent years, research on Tai Chi has made notable progress in improving lumbar disc herniation among sedentary populations. As a Chinese traditional form of exercise, Tai Chi is widely utilized in health management and disease prevention due to its low risk and high efficacy. Existing literature demonstrates that Tai Chi can enhance muscle strength, improve spinal stability, and correct posture, effectively alleviating lumbar discomfort and pain while providing significant long-term protective effects. Compared to traditional physical therapy methods, Tai Chi is gentler and easier to maintain, making it particularly suitable for individuals with sedentary lifestyles. This study aims to provide theoretical foundations and practical support for the promotion of Tai Chi in the prevention and rehabilitation of lumbar disc herniation, offering effective intervention strategies for health management in sedentary populations.
