knæstrækningen

Knæstrækningen, often referred to as knee extension in English, is a fundamental movement involving the straightening of the knee joint. This action is primarily facilitated by the quadriceps femoris muscle group, located at the front of the thigh. When these muscles contract, they pull on the patella (kneecap) and the tibia (shin bone), causing the lower leg to extend away from the thigh.

The functional importance of knæstrækningen is vast. It is essential for basic activities such as walking, running, jumping, and standing up from a seated position. In sports, it plays a crucial role in kicking, cycling, and many other athletic movements. Physiologically, maintaining the strength and flexibility of the quadriceps muscles through exercises that involve knæstrækningen is vital for knee joint stability and preventing injuries.

Common exercises that target knæstrækningen include leg extensions performed on specialized weight machines, as well as functional movements like squats and lunges where the quadriceps are engaged to straighten the knee against resistance. Rehabilitation after knee injuries, such as ligament tears or meniscus damage, often involves controlled knæstrækningen exercises to regain full range of motion and strength. The ability to perform a full and pain-free knæstrækningen is a key indicator of healthy knee function.
