Plyometrics involve hopping, bounding, and leaping
exercises and were invented by the very famous Russian
researcher Verhoshansky. Verhoshansky or Vert
for short pioneered these exercises in his work with
Soviet and eastern bloc track athletes in the mid
1970s. The incredible success of these athletes
in international competition led to closer scrutiny
of Soviet training techniques. Although plyometrics
initially met with some resistance from traditional
North American track and field coaches, they now play
a significant role in the training regimen of elite
athletes involved in sports such as soccer, basketball,
hockey, lacrosse, track & field, football, volleyball,
skiing, rugby, and competitive curling.
So how do we harness the power of the hop? The first
question to address is the issue of leg strength.
Research has shown that improving leg strength using
moderate to heavy squats alone can dramatically increase
vertical jumping ability. Ultimate players tend to
have legs that are skinny and wimpy. Facts are facts;
I have played this game for far too long to be convinced
otherwise. Plyometrics are demanding, high-load exercises
that can cause stress fractures, spinal damage, and
nauseating pain and anguish if they are done by someone
who lacks adequate leg strength. A good general rule
of thumb is to avoid plyometric training if you are
unable to comfortably squat a weight that is two times
your body mass.
If your leg strength is up to snuff you are ready
to engage in some light plyometric training. The idea
here is to start slowly and gradually accustom your
body to the huge external forces that are inherent
in plyometric training. Plyometrics involve repeated
jumping or leaping activities and take advantage of
the natural elasticity of muscle tissue.
The goal of plyometric training is to improve leg
strength, increase the elastic storage potential of
muscle tissue, and to improve the neural coordination
of muscle groups. Training of these elements allows
athletes to explode faster and more powerfully resulting
in improved vertical jump.
TO BEGIN
To begin make sure you have warmed up very thoroughly;
10-15 minutes of moderate to high intensity running
and a comprehensive stretch of all of the active muscle
groups is highly recommended. The exercises included
in this article can be done in a school field and
require no additional equipment like jump boxes or
hurdles.

STRIDES
Long a favored training method of sprinters and long
jumpers, strides are excellent for increasing stride
power and explosive acceleration movements translating
into faster sprints and more d-blocks.
HOW TO:
Measure out a distance of 7-10 yards
on a running track or school field. Approach the start
line at a slow jog and then bound from leg to leg
to the finishing line. Remember to explode as forcefully
as possible each time foot contact is made while driving
the knee up and forward. To begin, try 5-6 repetitions
between the lines and gradually work to higher repetitions
as your training progresses.
SKIPPING
Do you do the double dutch?
If not you should be aware that the hopping action
of skipping is a natural plyometric exercise that
develops explosive power and strength in the lower
leg. Long a stalwart of professional fighters (boxers,
wrestlers, shoot-fighters), skipping is breaking through
as a training method for other elite sport events.
HOW TO:
10-15 minutes of skipping is an excellent full body
warm-up and is a good way to begin a plyometric training
session. The intensity of skipping can be increased
by doing high double-leg hops, fast running, intervals,
and funky crossovers.
ONE AND TWO-LEGGED POP-UPS
This simple exercise is a favourite of volleyball
players and is a very effective way to improve leaping
ability from a stand still and can be done with one
or two legs.
HOW
TO:
For one-legged pop-ups take a large step forward
and pop off that foot as you bring the other leg forward.
For two-legged pop-ups step forward with the lead
leg and jump explosively off both feet as the second
leg joins the first. Remember during each jump to
drive your arms into the air and land on both feet.
To begin try 3 sets of 10 for each leg (single leg
hops), or 3 sets of 20 for the double leg hops.
HILL SPRINTS
Although this is not classified as an actual plyometric
exercise it is an excellent way to train for explosive
speed and power and is a great way to end the workout.
HOW TO: Find a hill of medium incline that takes 5-10
seconds to sprint to the top of. Start with 10 sprints
and make sure to leave adequate time in between sets
to recover properly.
THINGS YOU SHOULD KNOW
The exercises covered in this article represent a
tiny fraction of commonly used plyometric exercises,
and is only an introduction to some useful plyometrics
which can help develop explosive power and acceleration
for the sport of ultimate. It is very important to
remember that plyometrics are not exercises that should
be done every day or after every training session.
Most experts suggest a rest period of three days between
plyometric workouts. With proper training and adequate
rest, plyometrics can increase vertical jump by 2
to 8 inches and greatly increase your ability to react
quickly and powerfully. Good luck and happy hopping.

SUPERPEOPLES
Often called Supermans
and or Wonderwomans I have chosen a gender
neutral term for this fantastic exercise favoured
by basketball, volleyball, and rugby players. This
exercise does an excellent job of isolating the legs
and building power for one-leg takeoffs.

HOW TO:
Find a bench or box that creates an
angle of approximately 90( when you place your foot
on top. Using all your power, explode into the air
using the top foot and throw your arms above your
head as if you are bidding on a high disc. In mid-air
switch feet and land with the other foot atop the
bench. Repeat this motion as quickly and powerfully
as possible. The longer your leg stays on the ground,
the less elastic energy is available from the muscle
tissue so it is very important to move as quickly
as possible. To begin, try 3 sets of 10 for each leg
and increase the number as your training progresses.
REBOUNDERS
An advanced exercise that requires substantial practice
and core strength, this is superb for developing torsional
power and abdominal /lower back strength. This exercise
will add considerable power to your throws and vastly
improve your ability to imitate a Romanian gymnast.
HOW TO:
Start by standing parallel to a railing or beam that
stands 3 to 3.5 feet off the ground. Place both hands
together and in front of you. Pop over the obstacle
using both feet and swing your body using your midsection.
Concentrate on keeping your body and arms straight
throughout the action and pop as quickly as possible
to each side. Try sets of 10 to start.
