Definition
Every muscle in the body consists of many muscle fibers, which in turn are combined into muscle bundles. The muscle fibers are made up of even smaller units called sarcomeres. When a muscle fiber tears, individual muscle fibers tear.
This is caused by excessive strain. On the other hand, a rupture of a muscle fiber tears a whole bundle of muscle fibers. There are several muscles on the forearm that can be affected by a torn muscle fiber.
Causes of a torn muscle fiber on the forearm
The cause of a torn muscle fibre in the forearm is an overloading of a certain muscle. A tear occurs mainly during movements with fast, jerky movements and stops. Too extreme a movement can also cause a rupture of muscle fibers.
The risk of injury is increased by a muscular imbalance or by a low stretching ability of the corresponding musculature. Insufficient warm-up training prior to sport or a previous injury to the forearm can also lead to a rupture of muscle fibers when the arm is subsequently loaded. The use of anabolic steroids represents an additional risk factor for a muscle fiber rupture, as the muscle mass increases unnaturally fast.
In addition, accidents associated with an impact or collision can cause a rupture of muscle fibers. The trigger for this is above all a violent blow to a stretched muscle. When playing tennis, the torn muscle fiber on the forearm is a typical injury.
This is due to the fact that this sport involves fast and jerky movements with the arm. Especially if the forearm muscles have not been warmed up sufficiently, tennis players are very susceptible to torn muscle fibers. Playing golf, like tennis, places a very high strain on the muscles of the forearm.
Due to the fast and powerful strokes, the muscles can easily be overstretched and individual muscle fibers can tear. For these sports, a thorough warming up of the arm muscles is therefore very important. Climbing puts a lot of strain on the arm muscles. By pulling up in different directions, both upper and lower arms are put under a lot of strain. Overloading and missing or too short warming up of the arms can easily lead to tearing of muscle fibers.
