Paceman's Pacemaker - The shoulder - II
The most exciting element of cricket is to watch a
good fast bowler charging in and hurling a few
missiles that peg the batsman onto the back foot or
send the stumps cartwheeling. This the bowler can
do on a consistent basis only if he has strong,
powerful and 'fit' shoulders. The shoulders have to
be complemented with the proper technique, and that
is exactly what I will be explaining in this
article.
The process of fast bowling starts from the bowling
mark. The run-up has to be right.
A correct run-up gives the bowler the momentum to
gain power by the time he reaches the crease, and
to bowl quicker. Fast bowling puts a lot of strain
on the shoulder muscles, but the chances of
straining them or getting injured can be reduced to
the minimum if the run-up is smooth and proper. The
run-up has to be smooth and steady, with smaller
steps. The bowler should get into his delivery
stride gradually as he nears the crease. His arms,
legs and every other part of the body should move
forward.

We all know that the best way to bowl is either
side-on or with open-chested. There is no question
of having an action that is a mix of the two
approaches, as it will maximize the chances of an
injury. There are several ways in which a bowler
can judge his action and detect faults if any. One
of the best methods is video-recording, as it
enables the bowler to view himself in slow-motion
and thus makes it easy for him to examine each and
every movement of his. The better the technology,
the better are the results. But, the value of any
method depends upon the experience of the person
who is evaluating the picture along with the
bowler. The feedback of the coach, biomechanist or
a sports physiotherapist, all of whom ideally ought
to have a lot of sports-related work experience, is
one of the most important factors that can
contribute to the success of a correctional method.
A bowler should try and avoid using a mirror. This
is rarely effective, as the bowler then starts
concentrating on the position of his shoulders
while looking at himself, and this can reduce his
focus. After all, they are supposed to concentrate
on the batsman and the stumps at the other end.
Poor performance and shoulder pain have their
origins in faulty technique. They often occur when
muscle fatigue sets in. However, a good coach or
physio will be able to sense when something like
this is happening, and realize that it is time for
rest and recovery.
Faults:

The variety of overhead movements that are part of
the bowling process can give rise to some very
subtle and unique technical faults, like:
1.An open-chested bowler trying to bowl faster by
using his shoulder muscles excessively with
insufficient trunk-twisting.
2.a An open-chested fast bowler trying to hit the
seam harder & harder with the high arm action.
3. A bowler with a side-on action trying to take
his elbow behind his shoulder during his
follow-through.
The closer the line of the upper arm is to the line
of the front of the chest, the lesser is the strain
that is placed on the shoulder.
I hope this helps the reader to understand why a
fast bowler measures his run up, and why a paceman
sometimes stops in the middle of his run-up when he
realizes that he has lost his rhythm. Yes, it is
the run-up that gives him the rhythm to bowl
faster, and reduces 60-70% of the strain that is
placed on his shoulder.
Follow-through and finish:
A fast bowler should have a proper follow-through
and finish after releasing the ball to minimize the
chances of straining the shoulder in the last stage
of the bowling action.
While bowling an inswinger, a bowler should ideally
take his bowling arm and hand towards the inner
side of the front knee . If the hand moves towards
the outer side of the knee, it means that the
shoulder is moving in an opposite direction
(internal rotation). This puts a lot of strain on
the rotator cuff muscles, which ultimately leads to
a shoulder injury. Similarly, a bowler delivering
an outswinger should take his arm and hand towards
the outer side of his front knee. The chances of a
rotator-cuff injury are high if the arm goes
towards the inner side.
