The need for speed was not
only the anthem of Tom Cruise and partner in Top Gun, it is the catch cry of
most coaches in rugby and many other sports today.
But when analyzing the sport you are programming for and the positions within
that sport you will quickly come to the conclusion that top end speed or
maximal velocity is not necessarily the number one element of the speed
continuum.
I have often joked that the easiest and quickest way to increase the speed of
your team is to recruit faster players. In my opinion acceleration and power
are far more important areas to train because I think that you will get a much
better result for your training time investment. In this article I will address
the use of resisted training devices to improve acceleration and power.

Power Speed Sleds
|
 |
In traditional track training coaches use 5% of a persons bodyweight as an
indicator of the weight to use. This is reasoned by the point that too much
weight may later the mechanics of the sprint action and thereby effect the
transfer of training to the event specific. |
|
|
| In team sport this is not as
big a problem because the classic sprint action of track athletes is very
rarely attained in a game.
|
 |
Running tall is the best for top end speed running but most of the body
position in rugby and other sports is more like the acceleration out of the
blocks. A by product of this is that it is the ideal body heights for taking
the ball into contact and for cleaning out opposition players at the breakdown.
Just a caveat when using heavier loads it is relative back to their weight room
strengthen key movement such as clean and squat since you want to maintain good
forward lean and leg drive.
|
| A general rule that I have
used over the years is that you want to maintain speed over 80% when sprinting
with resistance. Any slower than this then the resistance is too much and you
may well be teaching the athlete to move slowly.
|
|
|
|
With
this in mind I will start after a dynamic warm-up with a load and then decrease
this over the session in order to elicit times greater than 80%.
Distances used in training should reflect those that are regularly used in the
game. So if you are unfamiliar just sit down and watch a game with pen and
paper and look at how far a variety of positions run. In rugby, I find the
three groupings I use front 4 (props/Locks) back 4 (center, wing & full
back) middle 7 (all the rest).
Allow me to run a session for all players but be specific in the distances.
Front 4 10,20 m
Middle 7 10, 20, 30, 40m
Back 4 10, 20, 30, 40, 50, 60m
To maintain a similar volume the number of reps at each distance is adjusted. I
will use around 250 – 400m of resisted work in a session. Of course this is
just a guide, you should always use the breakdown in technique player feedback
and the speed you want as a guide to when the session should be concluded
irrespective of what you have planned for the day.
Parachutes
 |
Another training tool that is used
regularly is the speed chute, similar in concept to sled training, but with
some great additional benefits.
The use of parachutes brings into play an increased number of stabilizer
muscles due to the nature of the wind resistance. With the wind shifting around
the person will be making number micro adjustments to maintain the running
line. |
|
The chutes come in two sizes and more than one can be
worn at a given time for stronger athletes. An additional benefit is the ease
at which the chutes can be released making them ideal for contrast training.
Contrast training has been very popular in the strength area for a number of
years and basically refers to the use of a major loading exercises used first
then usually a body weight or significantly lightened load used immediately
following the termination of the heavy set. For example, a heavy set for 5 reps
in a squat followed by body weight jump ups onto a box so with the parachute
you sprint out a set distance then release and sprint to a finish line without
any loading just like spinning your tyres when you are stuck in sand or mud and
then getting traction and flying out of the ruts.
So to contrast sprinting gives you maximum motor unit activation then once they
are turned on they can not be shut off and you explode away once the chute is
released.
When using this style of training in rugby I have the players work in pairs one
holding the chute open and throwing it into the air to fully inflate, the
player will sprint either from the ½ way line or try line which will give then
either of the following options:
22m Loaded 28m Free
28m Loaded 22m Free
28m Loaded 28m Loaded
Again keeping the resisted session between 250 – 400m will give you an
indication of how many reps you can do.
After you have used resisted speed I find it is a good practice to do some run
throughs at 80 – 90% of maximum with good technique so the player can feel the
difference. If the session has been one of low volume and the athlete is not
fatigued you could even do some top end range speed as often I have found
players to be faster after the resisted work. The resisted work as a very
neural/motor unit specific warm up similar to wave loading in strength training
where the second and third series of sets the athlete can use a heavy load for
the same number of reps as in the previous series.
By a way of a conclusion the format I follow in the building of a training
session is outlined below, just remember this is used with professional rugby
players with well developed training ages and should not be used like a cook
book recipe for the people you train.
Dynamic warm-up 10 minutes movement drills such as high knees, butt kicks,
skips marches, perform the drill for 10 – 20 minutes and then accelerate out
for 10 – 20 minutes walk back or continue to work up the field
Partner work holding your partner so they are balanced, hands on there chests
leaning them forward to at least 60 degrees step to the side and release them
into a acceleration action.
Plyometrics (60 – 100 foot contacts) bounds, skips, jumps, (attention to
technique and quickness off the ground)
Resisted work (250 – 400m) sleds or parachutes vary each workout if doing twice
per week. Run throughs form runs static stretch 10 – 15 minutes. The full
workout should take about an hour to complete, err on the side of too little
rather than going too much as the workout is the stimulus the improvement comes
through the recovery process.
Enjoy your training.
