Flexion

Flexion Flexion is a movement that involves turning around the frontal plane and bending the bones in the spine.

Flexion is a simple muscle effort in nature. Depending on which muscle group contracts more, different flexion occurs. There are several types of bending. Without the risk of injury, two types of flexion are used: 1. Full flexion - involves bending the joint to a right angle, that is, 90° or more. This situation can occur in an athlete who plays sports in a standing or sitting position. 2. Partial bending - that is, bending less than a right angle. There is a reason for a similar situation to arise due to intense but insufficient load during training: 75-95% of the range of motion. This situation is the cause of injury to the ligament and tendon area. “Overload” and partial flexion may occur if not trained correctly. The so-called traumatic angle of flexion is less than 65°, which can be called the focal angle of injury. When the knee joint is not completely fixed, there is strong pressure on the patella, a so-called tear of the ligamentous apparatus, usually the anterior one, occurs, and the articular capsule is damaged. Flexion of the joints of the spine, leg and neck muscles, in addition to sports training, can occur due to certain work performed in everyday life. These are movements without any particular danger or injury arising from them, so there is no point in paying much attention to them, a general description is enough. Professional gymnastics, skiing, bodybuilding - all of these sports contain a variety of exercises involving flexion of the limbs, neck and trunk (robotic actions), which have a specific risk of injury. Therefore, the description of individual types and their designations are as follows: 1. Pronation or supination of the forearm, hand, foot. This is flexion of the forearm at the ulnar axis and extension at the wrist joint. It belongs to the group of axial movements because it does not occur in the plane of the joints (it is supination). The bone core passes from the front downwards, forming an angle of 90-135°. The position of the elbow is in front of the body, the palm faces the direction of movement of the arm, leg, like the rest of the limbs,
