Muscle tear

Introduction In sports, due to improper preparation activities, the physiological function of a certain muscle has not yet reached the state required to adapt to exercise, the training level is not enough, the muscle elasticity and strength are poor, fatigue or excessive load, the muscle function is reduced, the strength is weakened. Coordination is reduced, the wrong technical movement or movement is not concentrated, the action is too fierce or rough, the temperature is too low, the humidity is too high, and the muscles of the site or equipment are poor.

Cause

In sports, due to improper preparation activities, the physiological function of a certain muscle has not yet reached the state required to adapt to exercise; the training level is not enough, the muscle elasticity and strength are poor; fatigue or excessive load, the muscle function is reduced, the strength is weakened Coordination is reduced; wrong technical movements or lack of concentration during exercise, excessive or violent movements; too low humidity, too high a quality of the site or equipment can cause muscle strain. When the various actions are completed, the muscles actively contract violently beyond the capacity of the muscle itself, or suddenly passively excessively stretched, beyond its stretchability, can cause strain. If the weightlifting exercise bends and grabs the barbell, the erector spinae is strained due to strong contraction. When doing exercises such as front leg presses and longitudinal squats, the sudden exertion is too strong, which can cause the muscles of the thighs to be excessively passively elongated and damaged. The cross-fork practice can cause the inner thigh meat to be excessively passively stretched and strained. In sports, the strain of the muscles in the back of the thigh is the most common. The thigh adductor muscle, the back muscle, the rectus abdominis muscle, the calf triceps, and the upper arm muscle are all prone to muscle strain.

Electromyography mammography

Local pain, tenderness, swelling, muscle tension, stiffness, cramps, dysfunction. When the injured muscle is actively contracted or passively stretched, the pain is aggravated, and the muscle contraction resistance test is positive, that is, the pain is aggravated or a broken depression occurs. Some wounded people have a tear-like feeling when they are injured, and the swelling is obvious and the subcutaneous congestion is serious. If there is a depression in the touch or an abnormal bulge at one end, the muscle may be broken.

Differential diagnosis

Local pain, tenderness, swelling, muscle tension, stiffness, cramps, dysfunction. When the injured muscle is actively contracted or passively stretched, the pain is aggravated, and the muscle contraction resistance test is positive, that is, the pain is aggravated or a broken depression occurs. Some wounded people have a tear-like feeling when they are injured, and the swelling is obvious and the subcutaneous congestion is serious. If there is a depression in the touch or an abnormal bulge at one end, the muscle may be broken. A symptom identification will not be misdiagnosed, asymptomatic identification.
