108 What are the hazards of bowing down?
It may cause patellar cartilage inflammation. Don't do difficult movements at once when practicing. You should strengthen the muscles in the front and back of the thigh first, so as not to hurt the knee joint.

Patella is a very special bone, located in front of the knee, which can reduce the force used by the knee. For example, when a person jumps, the strength of the whole body muscle flower 100 kg can be reduced to 60 or 70 kg with patella. Patella has the function of decompression, which can help to disperse strength.

Generally, when the knee bends 30 degrees, the patella bears about 10 kg per square centimeter, 45 kg at 60 degrees and 60 kg at 90 degrees. The greater the knee bending angle, the greater the pressure on the patella. As long as the bending angle is large and lasts for three to five minutes, the patella will be injured.

108 Please keep your hands on the ground, kneel down and keep your forehead on the ground. It should be noted here that the speed of kneeling should not be too fast, otherwise the impact on the knee joint will be too great. Feet should be properly separated, toes should support the ground and heels should stand up. At this time, the elbows naturally stick to the ground, and the inhalation is over.

Stand up straight with your hands on the ground. Mainly using the strength of the waist and legs, in order not to let the knees bear too much load, use the elasticity of the lower body to get up gently. Stand up straight and close your hands again. Then exhale.

The above actions are not separate and separated actions, but a coherent whole. Every movement can't be interrupted, every step and every breath are connected together to form a round circle.

Precautions when squatting: When squatting, relax the body to the maximum extent and make the body light and soft, so as to do every movement well and make the blood circulation of the whole body smoother.
