The ligamentous restraints surrounding the joint (i.e.; joint capsule
and the bands of the anterior glenohumeral ligament) normally provide
for a moderate degree of static stability). However, static
glenohumeral joint stabilization alone is inadequate for a pitcher.
This is because a pitcher repeatedly takes his or her arm through an arc
of motion at extreme speeds, placing enormous amounts of stress about
its axis of rotation. Werner et al. (17) studied the relationships
between throwing mechanics and shoulder distraction in professional
baseball pitchers.
They found that shoulder rotational velocities can
reach as high as 10,000 degrees per second and that distraction forces
greater than 947 N occurred across the shoulder joint during the late
cocking and deceleration phases of the overhead throwing motion.
Baseball pitchers must rely on the muscular component of their shoulder
to resist distraction forces and provide dynamic stability (2, 5, 7, 10,
17, 18).
Besides providing dynamic stability, these muscles, along with the
help of other extrinsic shoulder muscles, contract concentrically and
eccentrically to produce internal and external rotational torques during
pitching (6, 7, 17, 18)which enable an athlete to throw faster with
proper training and technique. Here’s the some of the tips
how to improve baseball performance .
The essentials of baseball are going to be truly straightforward, a
pitcher pitches the ball to some player who hits it & circles as
various bases as could be expected under the circumstances sooner than
the ball is typically recovered & returned under control with the
guarding group.
