​Part 3: What Science Says About
Skating Speed Development

"You just gotta get stronger to skate faster."

It's a training mantra repeated ad infinitum in sports.

I agree with it.

And I also disagree with it.

But before we tackle that statement, let's define the three most important forms of speed work for a hockey player so that we're on the same page moving forward:

1. Acceleration

The distance over which an athlete is able to accelerate prior to reaching maximum velocity.

2. Maximum Velocity

Skating at full speed.

3. Change-of-Direction Speed

Rapidly decelerating and accelerating in a different direction - forward, backward, diagonally or laterally.

With these definitions out of the way, let's talk more about physical strength and how it relates to speed development.

As a beginner, nothing will improve your skating speed as much as gaining lower body strength will.

(Apart from improving your skating technique which takes place on the ice, not off the ice)

​Research is pretty clear on the benefits of ​increasing ​leg strength for acceleration and change-of-direction performance​. [1-5]


The closer you get to reaching your strength potential, the less impact maximal strength gains will have on your speed and power.

​Don't believe ​it? Here's one example:

​A study done on D1 American football players concluded that increasing strength improved speed (40-yard sprint time)​ and power (vertical jump height) ​for about the ​FIRST YEAR.

​After that?

​Gaining more strength did not significantly increase ​the athletes' speed/power. [​​6]

​Furthermore, it takes ​EXCEPTIONALLY large increases in 1RM back squat strength (23-27%) to only slightly increase sprinting speed (2-3%) in intermediate/advanced athletes. [​​​6, ​​7]

​This means an imaginary hockey player ​who squats 160 kg (352 pounds) and runs a 4.00 30-meter sprint today would need to bring his squat up to around 200 kg (440 pounds) to witness his 30-meter time drop down to 3.92 seconds.

A ​​40 ​​kg ​INCREASE in squat strength would produce just a paltry ​DECREASE of 0.08 seconds in short-distance sprinting.

​From 160 to 200 kg. That's a two-year adventure, minimum. Longer if you play hockey at a high level.

​(Less time for off-ice training the higher the level of play)

​Not only that, there's no guarantee that the 0.08-second improvement in running will transfer into skating (where it ​REALLY matters).

While there's a strong correlation between dryland and on-ice sprint times, improving one doesn't automatically ​improve the other.

So even if our imaginary player managed to eke out a small sprint boost through strength training, he may not witness any change on the ice.

All that time invested and the increased ​toll on your joints in return for miniscule​ speed gains​?​

Not a very profitable training ROI in my books.

Especially considering how professional hockey players ​can improve their 30-meter skating times up to 0.277 seconds in only 13 weeks by using a combined strength + speed/power training approach.

​(​​More on this later)

If more strength isn't the answer, then what is?

​The more informed athlete will turn his sights to jump training to enhance his skating speed and explosiveness.

​Enter box, depth, broad and vertical jumps.

​But is that really the optimal ​solution?

​How well does bilateral power training transfer into skating?

What about the DIRECTION of force production?

Skating takes place ​HORIZONTALLY. But common VERTICAL jump exercises like box and vertical jumps continue dominating off-ice training programs.

Is their inclusion warranted? Or should we do something different?

I've been questioning the ​over-reliance on bilateral vertical exercises in unilateral horizontal sports (like hockey) for some time now.

And interestingly, research ​seems to agree with what I've ​noticed in practice. ​Check out these few tidbits on improving speed over short distances (a.k.a. ​ACCELERATION​):

#1. Increasing maximal sprint velocity appears to be more dependent on HORIZONTAL rather than VERTICAL force production. [8, 9]

#2. Enhancing sprint performance – especially over short distances – comes down to improving an athlete's HORIZONTAL force production capability. [10]

#3. Because skating is a horizontal activity, increased HORIZONTAL LEG POWER plays a crucial role in skating faster. [11]


​Same story as above:

​​Traditional strength and power training programs involving mainly bilateral vertical ​exercises ​(i.e. Olympic lifts, squats, deadlifts, vertical jumping) don't elicit huge improvements in change-of-direction (COD) performance. [​​12]


A potential reason for the gap between strength in vertically-oriented exercises​ is the ​LACK OF SPECIFICITY to horizontal planar movement. ​[​​13, ​​14]

How do you improve ​change-of-direction performance then?

By using exercises that more closely mimic the demands of a COD, including:

  • ​Horizontal jump training (unilateral and bilateral)
  • ​Lateral jump training (unilateral and bilateral)
  • ​Loaded vertical jump training
  • ​Sport-specific COD training
  • ​General COD training

​The last two items ​listed shouldn't be too difficult to understand.

Sport-specific change-of-direction training for hockey is simple:

It takes place on the ice. And involves powerful acceleration and deceleration over short distances in multiple directions.

One way to do that is by accelerating back and forth ​between blue line ​and red line, or blue line ​and blue line.

​General COD training off the ice isn't hard to grasp either. 

Something like the pro agility drill they use at the NHL Draft Combine works well.

You could also use the L-Drill often seen in football preparation programs.

Or running 5 meters backwards, then exploding laterally into a sprint for 10-20 meters.

The variations are pretty much endless.

But what about unilateral + bilateral horizontal and lateral jump training? Or loaded vertical jumping?

​How do you ​fit them into a comprehensive speed/power workout plan?

​Let's talk about that now.


#1.Past a certain point, more strength isn't the answer for speed or power gains.

#2. The ability to produce more force horizontally (and doing so ​rapidly) should become a focal training point for any hockey player who wants to skate faster.

#3.For increased acceleration and change-of-direction speed, you'll want to use more unilateral and bilateral horizontal and lateral jump variations rather than sticking to bilateral vertical movements.
