BENDING THE BALL |
TRAPPING |
A player
who can keep a ball close to his feet whilst running at full
speed and dummying round other players is a joy to watch. But
the player can only do this when the slightest touch moves the
ball exactly the distance and angle he expects it
to.
|
This
much-admired skill is achieved by the player striking the ball
with the side of his foot to put a spin on it which makes it
curve in flight. But the roundness of the ball must be perfect
to ensure that the trajectory of its path is even, otherwise
an ball intended for the top corner of the net may simply pass
centimeters outside the goal post!
|
Stopping
a long pass with chest, or thigh, or foot is a skill which
every top player must acquire. But he has to know exactly how
much rebound to expect from the ball so that he can judge
precisely how much to bend and move his body to stop the
ball.

CIRCUMFERENCE -1 |
ROUNDNESS -2 |
REBOUND -3 |
The
circumference of the ball must be the same all round so that
it will move predictably. The diameter of the ball is measured
at 10 different points and the mean average calculated. FIFA
Inspected ball should measure from 68.0 – 70.0, FIFA Approved
ball from 68.5 – 69.5 cm.
|
A
slightly uneven seam can change the ball’s shape by a
fraction. In this test, the diameter of the ball is measured
at 16 points and the mean average calculated. The difference
between the highest and lowest diameter must be no more than a
percentage of the mean diameter: 2% for FIFA Inspected, 1.5%
for FIFA Approved
|
The ball
is dropped 10 times onto a steel panel from a height of two
meters. FIFA Inspected balls must bounce between 115-165 cm,
FIFA Approved balls between 120 and 165cm. The difference
between lowest and highest bounce must be no more than 10cm in
both cases.

THE LONG
PASS |
Directing a ball with the head requires strong neck
and shoulder muscles and an eye for an often acute angle. A
player’s experience tells him how a ball should perform when
he strikes it but a ball which is too heavy and a ball which
is too light can fly off at the wrong height or angle and the
goal is missed or the pass misplaced.
|
A ball
which has absorbed too much water feels totally different from
a dry ball. It travels sluggishly, it won’t lift, or spin and
takes the skill and pleasure out of the game for both players
and spectators alike. And pity the poor goalkeeper who not
only has to be agile on a muddy pitch but to save balls which
are heavy and slippery with mud and
water.
|
A
perfectly-flighted pass from one side of the field to the
other requires considerable skill from the player, who must
judge the weight of his kick to perfection. This type of pass
is often made to the winger in space, who makes another
accurate cross for the striker to go for
goal.

Each
ball is weighted three times in a sealed cabinet. The cabinet
is sealed to prevent draughts affecting the scale. Balls
should weight between 410-450grams for FIFA Inspected, 420-445
grams for FIFA Approved.
|
This
test turns and squeezes the football in a tank of water 250
times. FIFA Inspected ball must not absorb more water than
add’s 15% to the initial weight of the ball, FIFA Approved
10%.
|
A ball
which loses pressure during a game is difficult to predict and
performs erratically. For this test, the ball is inflated to a
pressure of 1.0 bar and in 72 hours must lose no more than 25%
of air for FIFA Inspected, 20% for FIFA
Approved.

SHOOTING
WITH POWER |
SHAPE
& SIZE RETENTION -7 |
A goalkeeper has more time to save a weak shot
so strikers like to shoot with speed and power and the
crowd love it too. Tall, agile goalkeepers often make
spectacular saves. To do this, they must also have the
experience to judge the flight pattern of a fast-moving
ball and, to be fair to all players, this must remain
consistent throughout the match.
|
In this test the ball is fired 2,000 times
against a steel plated at 35 miles an hour. The seams
and air valves must be undamaged, and the loss of
pressure, or deviation in the ball’s circumference and
roundness, must be minimal.
