The symptoms of back pain in chest training may be caused by excessive accumulation of lactic acid, lumbar muscle strain, and lumbar disc structure injury.
1. Excessive accumulation of lactic acid: exercise without adequate warm-up or long-term high-intensity chest training will lead to anaerobic fermentation reaction in the body, which in turn produces a large amount of lactic acid accumulation in the lumbar muscles, leading to the symptoms of back pain.
2. Lumbar muscle strain: too strong chest training or incorrect chest training will lead to lumbar muscle pulling and injury, so that the lumbar muscle localized aseptic inflammation, which in turn affects the lumbar and the surrounding soft tissue blood circulation, so that the symptoms of lumbar pain.
3. Lumbar intervertebral disc structure damage: long-term irregular thoracic spine exercise or incorrect posture will lead to lumbar intervertebral disc structure damage, physiological curvature changes, compression to the lumbar vertebrae around the muscles and soft tissues and cause back pain symptoms.
As there are many reasons for thoracic and lumbar pain, it is recommended to go to the orthopedic department of the hospital for a clear diagnosis.
