Breaststroke is good for lumbar disc herniation: First, the patient’s waist, especially the intervertebral disc, is not weighted during breaststroke, which will not increase the pressure in the disc and will not aggravate the herniation of the nucleus pulposus, and when breaststroke is performed, the patient’s lumbar spine is in a forward arching state every time he comes up for air, which is good for restoring the physiological curvature of the lumbar spine. Secondly, breaststroke can enhance the muscle strength of the lumbar back muscles, which is good for preventing intervertebral instability. Thirdly, the lumbar vertebrae are in a relaxed state during breaststroke, which is conducive to the return of protrusion. During the whole breaststroke process, the joints, muscles and limbs of the patient’s whole body are exercised, which is a very good form of exercise for the rehabilitation of lumbar disc herniation and is of great benefit to lumbar disc herniation.
