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.

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

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.
