The Wrist Joint, Fingers and
Hands
Fingers and Hands
The fingers and hands are among the most complex
muscle groups. The hand has 24 bones and more than 20 joints.
The movements of the fingers are flexion, extension, adduction and
abduction (see below for definitions).
Most people do not exercise or train their fingers
and hands.
Finger flexion is important in sports that hold or
handle a ball. These muscles also are needed for strong grip
strength.
Finger extension is under-recognized for its
importance in keeping the fingers in balance. Finger extensors are
important to balance the strength of the flexors.
Finger adductors and abductors are important for
individuals who must have a wide finger spread such as in musicians.
The Wrist Joint
Strengthening and increasing flexibility of the
wrist protects the wrist from impact and repetitive injuries. In
every day activities, overuse of the wrist may lead to Carpal
Tunnel Syndrome.
In athletics, wrist motion is very important in
throwing activities. All muscles of the wrist require equal attention
for flexibility and conditioning to keep the muscle groups balanced.
The wrist joint can make all movements except
rotation. The muscle bulk is located in the mid-forearm, whereas,
the tendons of these muscles run across the wrist into the hand.
Most athletes underestimate the importance of increasing flexibility to
strengthen these muscle groups.
