Ankylosis is clinically known as ankylosing spondylitis, and excessive exercise does not cause ankylosing spondylitis. Ankylosing spondylitis is mostly caused by genetic, infectious and immune factors, resulting in the deposition of immune complexes in the small joints of the spine, which manifests itself in symptoms such as morning stiffness, limited mobility and low back pain. Excessive exercise does not cause ankylosing spondylitis. However, excessive exercise can cause lumbar muscle strain or lactic acid buildup, which can lead to symptoms such as lumbar muscle pain and short-term activity limitation. In daily life, excessive exercise should be avoided to prevent local muscle injury or inflammatory infiltration. If excessive exercise causes lumbar pain, activity limitation and other discomforts, you should be vigilant and go to the hospital in time for consultation.
