Xiao Zhang (pseudonym), who finished the postgraduate entrance examination, wants to use the holiday fitness to develop a good figure. In order to have a strong arm, the exercise of the barbell becomes a compulsory course for his daily fitness. Two months ago, when he picked up the barbell, he felt pain in his lower back and radiation pain in his left leg. Upon examination at the hospital, it was found that there was a lumbar disc herniation at the position of the waist 5 and 骶1, and it had already been pressed to the nerve.
The normal spine of the human body has a physiological curvature of "before and after Gong", but due to sedentary, the waist curvature becomes straight. When the barbell is lifted, the waist is stressed, and the "upright" waist is subjected to a higher load than the normal waist. After long-term compression, the liquid that protects the lumbar spine is easily lost, making the vertebral body hard, puncture the annulus, forming a bulge, and pressing to the nerve. Therefore, Xiao Zhang is a poor posture for sedentary burying hidden dangers, lifting the barbell will aggravate the formation of lumbar protrusion.
These movements are not appropriate and can hurt the waist.
Sit-ups: office workers are not suitable for sit-ups. Because the sedentary movement for a long time, especially the posture of bowing and bending, the neck and lumbar vertebrae have been subjected to greater pressure. A set of sit-ups in place requires repeated bending of the neck and a large load on the back muscles. Repeating the waist for a long time can cause the disc to protrude backward and compress the nerve.
Tennis: When tennis hits the ball, it relies mainly on the waist. Stretching the ligaments before exercise helps reduce sports injuries, and the front limbs, waist, and arms need to be preheated.
Yoga: Certain yoga poses and practice methods, such as long bending, can also increase the pressure on the lower back.
