Legs

The quadriceps is a four-headed muscle group, originating at the front of the pelvic bone and forming the strong group of muscles that extend to the top of the knee. The quadriceps are used to extend the leg so are important for any running activity as well as strength for pushing off. The quadriceps also assist in flexing the hip so are important for side to side movements, jumping, and rotating activities. The quadriceps end in the quadriceps tendon at the top of the knee, so they have a key role to play in the health of the knee.
