VISION TRAINING
"Vision training for sport is the
application of specific exercises
conducted over a period of time that
leads to neural restructuring of cortex
and brainstem pathways allowing a
person to maximise efficiency while
performing visual perceptual tasks
leading to enhanced visual motor
performance”

Hockey Specifications
•
•
•
•
•
Puck black disc shaped
3 inch’s in diameter (7.6cms) & 1 inch thick (2.5cms)
Ring 61 metres long by 30 metres wide (international)
Net 1.2 m high by 1.8 feet wide
Slap shot - puck speed about 130-145kph range, average
passing speed of the puck from player to player is around 50 to
95 kph, variable due to distance and the opposing players in
the way

Gaze control
•
•
•
Vickers 2004-2006: Is gaze control is a factor for
successful scoring on penalty shots in ice hockey
Found that highly-skilled shooters use a head-down
approach at the time of the shot, and focus most of
their gaze on an area of the ice located on or just in
front of the puck
lower-skilled shooters use a head-up approach and
focus most of their gaze on the target, which tends to
be the goalie or the upper corner of the net
Gaze control
•
Vickers concluded: "Given that the head-down
shooters were more successful, it may be that this
style of shooting is more difficult for goaltenders to
read because the shooter provides fewer cues about
where the puck is going”
The Quiet Eye Phenomenon:
•
Panchuk study 2006 - shooters taking unobstructed
shots on goaltenders from close distances, closely
mimicking the NHL's shootout procedure that decides
tied games
•
Study shows that the distance of the shot doesn't
seem to matter, as long as goalies concentrate their
gaze on the puck and stick in the critical second
before it's released
Peripheral Awareness
•
The ability to focus on the appropriate key (i.e.
the puck carrier) and still maintain an awareness
of overall play/action
•
Allows the players to use a 'heads up' skating
style and still be confident in his puck handling
Peripheral awareness drill
Multi-coloured jerseys
Equipment: Hockey Puck
• Duration: 3 to 5 minutes
• Description:
1. Use an area ¼ size of the regular playing field
2. Divide players into 3 different groups of colours
3. Start with one puck
4. Players only pass to 1 colour & can only receive
from 1 colour. Eg red passes to blue, blue passes
to yellow and yellow passes to red
5. Add 2nd & 3rd Puck to the drill to increase difficultly
•
Peripheral awareness
•
Wayne Gretzky – hockey experts say his peripheral
vision was his main competitive advantage
•
“I had trouble playing the NY Islanders. Same colour
pants, I always know where everybody is around me,
do it by taking quick side glances without pulling my
head up. You don’t have to see a guy’s insignia on his
sweater to know what team he’s on. All you need is a
split second glance”
Visual search strategies
•
•
•
•
•
Gaze characteristics of elite & near elite athletes in ice
hockey defensive tactics Martell & Vickers 2004
Used a live defensive zone task
Regulated their gaze using 2 different gaze control
strategies
A quick cascade of fixations/tracking allowing rapid
access to contextual information & building a early
situation assessment
A stable object-oriented quiet eye to effectively control
the opponent at the conclusion of the task
Visualization
•
•
A Solid technical and tactical performance can
only be retrieved when its clearly represented in
the mind
Good visualisation technique includes full reality
of the game, the players involved, the spectators
and the atmosphere of the stadium
Eye hand coordination
•
The process of taking a pass and accurately shooting
to the open part of the net is one example of this skill
•
Plays an important part in deflecting shots and
knocking down high passes in order to control the
puck, or in helping a goalie to make a glove save
Visual memory & concentration
•
? Skilled players can recall & recognize patterns of
play more effectively then less skilled players
•
? Expert players use their knowledge of situational
probabilities (expectation) to anticipte future
events
Visual memory & concentration
•
Since the puck remains tiny in comparison to the size
of the ice surface and the players, players need visual
concentration skills to see it in a crowd. Players should
practice following the puck through a crowd of players,
which can become difficult as they become fatigued

The Hockey IntelliGym™ is a software-based
training tool that helps players develop hockey
sense – the perception and decision-making
skills necessary to stay one step ahead of the
puck and the game.
Developed by USA Hockey
Decision making process of ice hockey players
•
Step 1: Observing how & where the puck is coming from
•
Step 2: Knowing where teammates are on the ring
•
Step 3: Knowing where the opposition are on the ring
•
Step 4: Deciding what to do with the puck ball after a good first
touch
•
Step 5: Knowing your options by observing where the puck is
to be moved or passed
•
Step 6: Deciding when the puck goes
•
Step 7: Deciding how the puck goes
•
Step 8: Deciding why the puck goes (the tactical objective )

SUMMARY/TIPS
•
Conduct “hardware” assessment and
relate results to on field performance
•
Treat “hardware” deficiencies
•
Work closely with sports scientist/coaches
to assess/train & enhance specific visualperceptual parameters related to specificity
to ice hockey at all levels
