Playing table tennis has several effects on the lumbar spine: first, accelerating degenerative changes in the lumbar intervertebral disc, degenerative changes in the lumbar intervertebral disc is the result of multi-factor control. The lumbar intervertebral disc decreases with age, the water content of the nucleus pulposus and the fibrous ring decreases, the degeneration of the original fibers and the deposition of collagen fibers increase, the nucleus pulposus loses elasticity, and the fibrous ring degenerates. This degenerative change in the disc is prone to rupture under sustained external pressure, leading to disc herniation; second, overload, the upper body weight continues to cause compression of the lumbar intervertebral disc when playing table tennis, leading to increased internal pressure in the lumbar intervertebral disc, prone to rupture of the annulus fibrosus, causing lumbar disc herniation. This leads to nerve compression, nerve edema, and conduction dysfunction, causing lumbar pain and lower limb radioactive pain, numbness, and weakness.
