During the past ten years I
have been involved in skating performance testing of individual hockey
players and hockey teams from all over the world. This testing was
part of a very comprehensive study that
analyzed skating performance in 14 basic game fundamentals.
Representing some of the International participants were players from
Korea, Japan, Germany, Switzerland, and England. Representing North
America were players from Alaska, Michigan, California, British
Columbia, Alberta, Saskatchewan, Manitoba, and Ontario.
I will endeavor to put this testing analysis into a visual format that will create a clear picture of the relevance as well as the application of the testing process.
Skating is the foundation of the game. How much so to date has not been clearly understood.
- Are goal scorers better
skaters or is it just their ability to read the play and shoot
Shown below are some of the tests that were performed. While testing is diverse and further information regarding these tests can be attained through the parent company Quan-Tech Sports Inc. I have chosen only the ones explained below. While the tests are very simple and specific, the relevance of these tests and their subsequent impact on the game both from an individual as well as from a team perspective. is dramatic. I have made the explanations very brief since I feel that too much technical "babble" is not necessary at this point. However, I have endeavored to provide enough information to demonstrate each test's relevance to overall game conditions.
are as follows:
lower body strength and power
for effective lateral mobility
No.7 - Backward Full Stride test; identifies strength / weakness
each player uses his assets and protects his liabilities dictate his
success story - not with-standing heart and desire.
I have provided some of the technical considerations that as an instructor I
must evaluate and correct before a
player can perform skill function to its
Forward "V" Start Acceleration
Forward "V" Start - Top View
Forward Striding Front View
Striding - Top View
Backward Striding - Back View
Forward Parallel Stop
Forward to Backward Pivot - Direction Change
Each fundamental is critical to a player's success during game play. One-on-one confrontations create
a very competitive environment where the player with the "edge" has greater success. This "ballet"
of inter-action between players creates situations where weaknesses and strengths become evident.
When neutralizing an opponent or "getting open" a player will quickly realize how well he utilizes his
strengths and how well he protects his weakness.
In the hockey world where games and careers are won and lost, these player attributes become quite literally, either an asset or a liability.
However, in society today we tend to view testing as a negative experience. It seems that information is constantly being used against us. When I was testing in Switzerland, several players coasted through the tests and I had to send them off the ice and delete their times so as not the skew the study. They felt that the owner ship was going to use the information against them for contract negotiations. On the other hand, most of the players wanted the information so as to focus on their development. They were true competitors. The information allowed them to identify where they ranked against other players at their own level and target their off and on ice development to maximize their skill.
When I tested the Seibu Bears from Japan, they asked for a complete report on all players; how they ranked relative to each other as well as how their data effected team performance.
It is entirely up to the player as well as the coach, the quantity and quality of information that they wish to see.
The following is a player model which I will call player "X". The objective is to give you an example of how the information creates a performance model.
In order to give a better assessment of a player's ability I have created a ranking system based on a scale
of 0 to 10 (based on actual percentile).
Since default rankings are against total relative division player pool, the higher the score that a player attains overall, the better the player's ability to contribute to his team through his skating skill. If a player competes at the Junior A - Tier II level, he is only compared to players at that level unless otherwise specified.
This allows us to better assess his "assets and liabilities". These assets are broken down into backward skating fundamentals and forward skating fundamentals. For example:
Backward Skating Assessment for Player "X"
Test Description Time Percentile Rank
1 Backward Crossover 10.65 6% .6
2 Backward Crossover 10.59 9% .9
3 Backward Acceleration 2.10 56% 5.6
4 Backward Full Stride 5.61 28% 2.8
5 Backward/Forward Pivot-L 3.41 64% 6.4
6 Backward/Forward Pivot-R 3.53 38% 3.8
7 Forward/Backward Pivot-L 4.40 80% 8.0
8 Forward/Backward Pivot-R 4.28 98% 9.8
Average Ranking 47% 4.7
Forward Skating Assessment
A Forward Crossover - L 8.52 50% 5.0
B Forward Crossover - R 8.22 77% 7.7
C Forward Acceleration 1.54 80% 8.0
D Forward Transition Stride 2.59 97% 9.7
E Forward Full Stride 4.29 70% 7.0
F Tight Turn - L 3.69 98% 9.8
G Tight Turn - R 3.41 99% 9.9
H Stop/Start - L 3.16 99% 9.9
I Stop/Start - R 3.40 98% 9.8
J Agility without puck 4.79 57% 5.7
K Agility with puck* Not included in this assessment
Average Ranking 82.5% 8.25
Using Player "X's" scores we can clearly identify his strengths (assets) and weaknesses (liabilities) using game applications.
An understanding of the physics and methodology of skating fundamentals helps to pin-point the cause and effect in relation to his scores.
Skating can be broken down into 2 basic categories and can be demonstrated as follows:
Technical Attributes Physical Attributes inherent in skating
1. Balance 1. Static strength
2. Body alignment 2. Explosive Power
3. Foot Speed 3. Quickness
4. Edge control 4. Flexibility
5. Technique 5. Muscular endurance
As well as Aerobic and Anaerobic Capacities.
Each test is designed to specifically target one or a combination of these components.
When we further analyze Player "X's" times and rankings we can gain a clear picture of not only his skating style but his physical structure as well.
Player "X's" low ranking in backward crossovers (T1- 6-9%) can be attributed to poor body alignment and balance (upper body bent to far over is one of the most common problems). Poor upper body alignment causes slippage off the front part of the skate, especially the inside foot / outside edge minimizing power. This is also evident in the backward acceleration test (T6 - 56%) where scores are again low. Low scores in the backward full stride (T7-28%) are again the result of poor body position as well as poor technique (improper C-cuts and hip rotation or turn in is one of the most common problems).
Knowledge of the "cause and effect" of skating deficiencies allows us to cross-examine Player "X's" evaluation report. From the information provided in the report we can see that this player does not work on his backward skating. An important game skill is the ability to face the play. Once identifying Player "X's" problem as being weak backward skating we would then study his game play to see if he turns his back on the play.
This critique is further substantiated by his forward skating assessment.
When assessing Player "X's" forward skating ability we see further evidence of his bent over skating style. A bent over skating style during forward crossovers (A/B - 50-77%) again results in loss of power from the inside leg/outside edge. This is also apparent during the agility test (J - 57%) where scores are again average. Poor body position contributes to a problem moving laterally side to side within the 16'6" distance between markers. Any slippage off of the inside foot limits power bringing the body back over center. It is evident that this player does not feel comfortable bringing his skates back and forth across his body or into his center.
His skating style is that of a winger - adhering to a "keep in your lane coaching philosophy" or a player that is a habitual straight liner, working his way down the ice in a series of straight line attacks. Forward acceleration scores (C - 80%) demonstrate that his forward acceleration is good, the result of short powerful strides which allow him to attain a very good score in the medium distance sprint test (D -97%) distance. The 60 foot test measures a player's skating ability through the transitional phase from accelerating to full open-ice striding. Good full striding technique requires complete extension of the leg and foot as well as proper recovery position under the body on the outside edge. The drop-off of his score in the full stride test (E - 70%) shows that he does not complete his stride to full extension (most common problem with full striding technique) and is a wide tracker (does not bring his recovery leg back under his body - outside edge).
Upon completion of the analysis we can now rate this player on his strengths and weaknesses and answer
the following important questions:
How can he contribute to his team? How effective is he? How does he use his strengths (assets)? How well does he protect his weaknesses (liabilities)?
Player "X's" overall skating strengths and weaknesses are by-products of his position. This is evident by poor backward skating fundamentals. As a forward however his skating skills are valuable assets. High tight turn and stop/start scores enable him to be successful down low. These skills enable him to react quickly to transition and puck movement allowing him to keep involved in the play. He can work both sides of the ice well which would make him a valuable asset on specialty teams. However, his bent over skating style, poor backward skating and dependence on his tight turns limit his ability to face the play which could make him a liability on the penalty unit. As well, tactics that utilize lateral movement (crossovers) would suffer as well. While possessing good speed , a valuable asset when driving to the net or forcing the puck carrier, situations where angling is necessary become compromised and success is limited.
Scores high in tight turns (F/G - 98%), stop/starts (H/I - 98%) and forward acceleration (C - 80%) identify good leg strength, explosive power and leg speed. These skills are critical components of good checking and hitting fundamentals.
Further analysis can be done by cross-referencing more of the information. However, space is limited and at this time it is not prodent to do so. Any questions that you may have can be directed to me personally.

Testing - Team System Relationships
The C.A.T. system of test / retest follows a set progression derived from game situations, moving players
through a chronological process from testing, analysis, correction and training. For example:
1. Identifying game inherent skills; tight turns, stops and starts, etc.
2. Testing game skills; tight turns, stops and starts
3. Analyzing information: feet per second, player potential.
4. Providing an environment for improvement: knowledge leads to better practice planning.
5. Teaching of fundamentals in a skill specific environment.: Utilizing the practice.
6. Adding pressure to skills: competition drills to create game situations.
7. Identifying game theory applications and executing in a practice environment: cycling, delay options, etc.
8. Playing of games to assess strengths and weaknesses: 2-on-2, 3-on-3, down low mini-games.
In order to understand the relevance of the information presented in the previous chapter we must create a link
between each specific skating analysis and its game application. Hockey can be broken down into 2 basic
1 - those skills involved in the short game (30 feet and under)
2 - those skills involved in the long game (30 feet and over).
In this chapter we will establish the relevance of distance, speed and skill and how testing can help to pinpoint weaknesses in individual as well as team play.
In diagram no. 1 we are trying to create an environment where we can directly analyze a player's skill level not only at a personal level but at a team level as well. The above diagram represents a game situation in 3 stages.
1 - Team has initiated a break-out option to the near side with the center supporting.
2 - Lanes have been filled with players supporting each other as the puck moves through the neutral zone.
3- Puck has moved into the offensive zone with puck carrier initiating a delay option play, with support down the near wall and a late man moving up on the play.
In each zone specific skating skills are inherent to the success of the team's operating system.
1 - Defensive zone: quick acceleration. Capitalize on opponents' static positioning. Quick acceleration in the form of crossover starts, running or "V" start, as well as accelerating through a curve (crossovers).
2 - Neutral zone: maintaining speed through angular cuts or straight ahead.
3 - Offensive zone: de-acceleration, slowing down, stopping, delaying, tight turns, Once attack has lost momentum, players again resort to short game skill and speed.
We must break down the above diagram to understand game to practice to testing relationships.
Diagram No. 1 represent Defensive zone player movement. Diagram No. 2 represents breakout practice.
Diagram No. 1 Diagram No. 2
Diagram No. reflects tests that mimic player movement relative to game and practice enviroments.

Diagram No. 1 shows only the defensive zone excluding defensive players. Lines in the diagram
represent movement of players (skating patterns):

F2 is in a support position
F3 skates into gap in neutral zone and receives pass
D2 is in support position in front of net
Players move out of defensive zone into neutral zone with speed filling lanes.
Diagram No. 2 shows a basic drill to mimic above game situation.
Coach dumps puck on net and players breakout by moving into proper support positions.

Testing Team Development Relationship
In order for a player to maximize skating potential, a series of drills must be implemented during the practice format. Most "power skating" developmental exercises can be used. Certain exercises are used during power skating and can be utilized during practice. It must be remembered that power skating programs are short, intense training sessions that focus on one or many skills. This is due to the pressure to maximize development of all skating skills in a short period of time due to the costs involved. At 50$ to
200$ per hour, players and parents expect results in all areas of skating in a very short period of time. At the amateur hockey level we have strayed away from form correction during the practice format and focused more on system implementation. . This is due in part to a lack of knowledge of skating techniques. However, drills can be used that will accomplish results just by "doing" them without the pressure on the coach to be the "expert".
One of the most basic and most important components of skating is balance and edge control. While all
hockey players exhibit good balance, edge control is a major problem. This is due to either ankle strength,
poor body alignment or even miss-alignment of the blades on the boot. This problem should be checked
every time a new pair of skates are purchased. In most cases, the blade is mounted incorrectly creating an
inside edge dominance. Both fundamentals can be enhanced by performing a simple exercise for a couple
of minutes a practice. In the diagram no. 1, a player is skating through the neutral zone balanced on one
leg zig-zagging back and forth from inside to outside edge.
This drill will be difficult for younger players but should be done no matter the age. Increasing levels of difficulty enhance the training effect. Increasing speed as well as movement from side to side to jumping and landing on alternating edges will achieve maximum results. This drill should be performed both forwards and backwards.
The following diagram represent one leg balance and edge control used in above drill.
Key teaching points:
- keep knees and ankles flexed. (A and B)
- keep weight aligned properly; shoulders over knees, knees over toes. (D)
- keep head erect and stomach/abdominals tight.
- extend leg (straighten) on thrust (inside and outside edges) and flex on recovery (transferring edges)
Perform at the beginning of practice for several minutes both backwards and forwards.
testing has identified problem areas, how can coach's set about implementing a
developmental plan that addresses player's or collectively, team weaknesses?
drill variations demonstrated below are basic formations for developing proper technique. Inherent in each drill are
components that are critical to it's successful execution in a game environment. Power skating instructors have utilized a language that, much
like hockey coaches within the game and practice environment, address these components. Terms such
as gliding leg, skating leg, knee and ankle flexion, and recovery gap depict visual models for correction.
During power skating camps, players execute the above maneuvers once correct form has been demonstrated, while receiving verbal cues from a professional. The problem with most amateur and even professional coaches is that they do not consider themselves knowledgeable enough to make these verbal corrections. They instead are more concerned with movement within the drill itself speaking in terms of space and speed as opposed to technique.
However, if a player executes the above mini-drills enough, noticeable improvements will result. Since the majority of these drills represent short game play, reaction time will improve. Overload training will also occur due to the forces placed on the thighs and gluteals during the crossovers, stop - starts, and tight turns. Players not only will improve their technique but will become stronger as well.
What is necessary then is to identify how to place the above mini-drills effectively within a normal practice environment. A normal practice environment is one that deals with team systems as opposed to isolated player skill development as incorporated by hockey and skating schools.
diagram demonstrated below is a common swing drill used by many coaches. It has been given many names from
"horse-shoe to St. Louis" but is a basic swing with players skating down the wall, swinging through the top
of the zone to receive a pass from m the corner and then proceed down the ice to take a shot on the net.
Using a format of 15 skaters (3 full lines) we have work to rest ratio of 1:7.5. The drill incorporates approximately 200 feet of straight line skating with a low load crossover swing across the top of the zone with minimal crossover activity attacking the net. What we want to accomplish through modifying the drill is to increase crossover and tight turn development which has been identified as a team weakness, as well as to increase work to rest ratios.
basic drill can be "spruced up" to add necessary components. For
All tests identify inherent game skills. Once weaknesses have been identified, developmental components have to be implemented. Testing - development integration is my area of expertise. Questions and comments can be addressed via E-mail regarding information posted on this page. There is much more information that unfortunately I cannot post here due to volume of content but will endeavor to make available as time and space permits.
