Toe Length
• Hook
– Popular with defensive players due to the large
stopping surface; this helps receive the ball
– J-shaped construction
– Particularly good on grass surfaces
• Maxi
– Large receiving area and greater hitting power
– Defensive players prefer this stick style
• Midi
– Large hook surface and length
– Greater hitting and stopping area to aid receiving,
flicking, and reverse stick play
– Best for beginners and midfield players
• Shorti
– Designed to allow quick movement around the ball
– Generally used by offensive players

Length
• Traditionally senior hockey sticks have been 36 inches or 1 yard
long, the standard length has increased to 36.5 inches. At this point
in time there is no set restriction governing the maximum length of a
hockey stick but manufacturers tend not to produce many sticks of
more than 38.5 inches. However some manufacturers can take
special orders for lengths up to 42 inches.

• On defense, a longer stick is useful to provide a longer reach and to
allow the player to drive the ball further.
• On offense, a shorter stick improves a player's stick handling skills

Weight
06/03/2013 Engr. Shan Imtiaz
How does a stick's weight affect its
performance?
• 19 - 20 ounces (approx. 540 - 565 grams) - Designed for
forwards, a lightweight stick doesn't interfere with, or
hold back rapid stick work.
• 21 ounces (approx. 595 grams) - Designed for
midfielders, a mid-weight stick benefits both defensive
and offensive maneuvers.
• 22 - 24 ounces (approx. 620 - 680 grams) - Designed for
backs, the heavier sticks put serious power and distance
behind your shots, making them great for clearing the
ball.

Composite Materials • Fiberglass
– Light weight used for offensive players
– Durable and less rigid
– The material prevents wear and tear on the stick.
– Cheaper
• Carbon
– Provides a boost in hitting.
– One drawback to adding carbon to a hockey stick is how it reacts in
frigid temperatures.
– Following a hit, the vibration can be felt throughout a player's body.
– More expensive
• Kevlar,
– lessens the vibration by absorbing the shock of the hit to the toe of the
stick.
• Dyneema
– acts like a giant shock absorber.
– The coating is usually added at the base of the shaft. 06/03/2013 Engr. Shan Imtiaz

• 30% Carbon 10% Aramid 60% Glassfibre
• Varying levels of composites alter the
– Performance
– Weight
– Power and
– Stiffness of a stick, as well as its price.

Conventional vs Composite
• Wood
• Cheaper
• Softer feel
• Poor consistency
• Moisture effective
loss of power
• Composite
• Greater power
• Consistency (weight,
stiffness and power)
• Harsher, less refined
feel for the ball
• Expensive

Manufacturing
• A hockey stick is produced in two parts—
the blade and the shaft.

Composite Field Hockey Stick
1. Several layers of the composite material (fibers that
have been pre-saturated in epoxy resin) are wrapped
around a mold in the shape of the stick shaft.

2. Heating and pressing the unfinished stick
shaft. There are several ways to do this.
Conventional methods include placing the fiber-
wrapped shaft in a mold of a similar shape. The
composite material can then be pressurized
and compacted
– by applying hydraulic pressure to the shaft,
– by using vacuum pressure to force the composite
material against the mold or
– by using an inflatable device to force the composite
material to push against the mold.

3. Attach the stick shaft to a blade by
coating the peg on the end of the stick
blade with hot glue and clamping it into
one end of the shaft. Insert a rubber plug
into the other end of the stick shaft. Leave
the finished stick to dry.

Field Hockey Ball • A field hockey ball is required to be spherical,
• Weight between 156 and 163 grams
• Have a circumference of between 224 mm to 235 mm.
• The ball can be smooth or dimpled.
• Smooth Balls are usually used for Indoor (could be used
for outdoor training)
• Dimpled Balls are usually used for Outdoor. so that it
runs smoothly along the turf.
• A field hockey ball is made of all plastic. The plastic
depends on the weather and field conditions.
Polyurethane balls will not shatter under cold conditions.
Vinyl balls are great for hot weather, but freezing
conditions could make the ball crack and break.
