The Ankle and Knee
Ankle
The ankle is important in all walking, running and
jumping activities. It provides the major push in propelling the
body forward and upward.
The ankle has two movements, flexion and
extension. The ankle and proximal foot muscles and ligaments
contribute to two other "ankle" movements of inversion and eversion.
Developing muscle strength in the ankle and foot,
especially those muscles of inversion and eversion, help prevent ankle
sprain.
Knee
The knee is a very complex joint.
The knee joint is a hinge joint and its action is similar to the movement
of a door on hinges. Many ligaments and muscle tendons provide for
the stability of the knee. The knee plays an important role in shock
absorbing during jumping and running. The basic movement of the knee
joint is flexion and extension.
Twelve muscles move the knee. They are
grouped into three groups: quadriceps in front, hamstrings in the
back and adductors near the groin.
Knee extension facilitates jumping, running,
kicking, lifting, pushing and "cutting" - changing direction in movement.
