The best swimming posture for patients with lumbar disc herniation is backstroke or breaststroke. These two swimming postures not only exercise the lumbar back muscles and the joints of the whole body, but also do not increase the pressure of the intervertebral disc, do not increase the extrusion of the disc on the nucleus pulposus, do not lead to the aggravation of the herniated disc, and do not aggravate the back and leg pain, so it is the best exercise method for patients with lumbar disc herniation. In the process of swimming should pay attention to several points: first, the amount of swimming should not be too large, not more than half an hour each time; second, backstroke and breaststroke exchange positions for exercise; third, the water temperature should not be too cold, if the weather temperature is low, do not go swimming, so as not to feel the wind and cold dampness, resulting in aggravation of lumbago.
