A muscle tear can occur during the practice of a sport, but also in situations of everyday life.
Most often, when we talk about tearing, this is what is commonly called a "breakdown" which is a breakdown of the fibers in the muscle. However, a real muscle tear is more rare and corresponds to the complete rupture of the muscle.
The muscle tear is a muscle fiber injury, most often when there has been excessive stretching or a very violent contraction of the muscle that has been stopped abruptly. It is the rupture of a part of the fibers of the muscle, either in the body of the muscle, or at the junction of the muscle and the tendon, or the muscle and its envelope.
The lesions are classified in degrees of increasing severity, from 1 to 4, depending on the severity, the number of affected fibers, if they are very disorganized, if the envelope of the muscle is reached, etc.
This article written with a sports doctor makes the specific point about the causes, symptoms and treatments of a muscle tear, with lots of practical information on what to do ... and not just after 'accident.
Tearing occurs most often when the muscle's elastic resistance capabilities are exceeded, and it usually occurs when there is muscle tension before or during contraction. For example, in the case of a sudden sprint start, but also a reception where one contracts violently to cushion the shock (when the muscle is stretched and contracts at the same time).
Muscular tears can be observed in sports ... but also in a jumping reception, for example, in everyday life. Thus, there are very common lesions of the Achilles tendon or calf muscles in people who simply jump over a ditch and receive with the foot very flexed.
Tennis is also a frequent cause of muscular accidents: players are often victims of "tennis-leg", a calf breakdown. In fact, this kind of injury can be found in all sports with fast starts.
In ball sports, injuries are observed during the game, of two types:
> When people start to shoot with the foot, ie when the knee is bent very far back before throwing the ball, and there is a sharp stretch of the muscles of the thigh (the quadriceps, muscle on the front of the leg).
> When they have finished throwing and the back muscles (hamstrings) must control and slow down the leg at the end of movement: in this case, the lesions are frequent.
There may be muscle damage at all levels, but more frequently at the lower extremities.
