When performing jumps from height it is imperative to know how to
land and roll properly. If you have not mastered the roll then it
is important not to attempt any techniques that require it. Until
you can distribute your weight correctly, and effectively minimize
the impact on your bones and joints, you should not jump down from
drastic heights. There are always alternatives to jumping. Although
they are sometimes slower, they are always safer.
One alternative which can be as fast as jumping is hanging down and
releasing. When approaching the edge where you might jump, instead
perform a turn vault. You should land in a position similar to the
landing of a cat leap with both hands and feet on the wall. From
that position, since you are now an entire body length closer to
the ground, you can release and land. Once this technique is
mastered, you can decrease the time in which you are not moving
forward by kicking off the wall going into your landing. This can
be as fast as jumping, because you are replacing hang time with
ground contact. A person can always travel faster on the ground
than in the air. Also you have eliminated the need for a roll and
can replace that time with running which is always faster. Although
speed is lost when slowing down for the turn vault, you make up for
it by increasing the amount of running.
A second alternative to jumping is finding a different route.
Safety is the most important thing to keep in mind when practicing
parkour, therefore beginners especially should consider this
option. When jumping seems like the only choice, take a moment to
survey your surroundings, find a new path, and temporarily change
your direction. Finding an alternate route may lead to the
discovery of a new training area, and is ultimately the safest
choice for many people.
To ensure safety when learning the roll it is important to build
technique slowly by working up to harder surfaces and higher jumps.
When first starting out, practice your rolls in a gym or soft
grassy area in order to get the movement down and build confidence
without hurting yourself. Have someone you know watching in order
to critique your technique and help you improve. It would be even
more beneficial to video tape yourself in order to analyze your own
movements later. Start from a standing or crouching position before
attempting jumps off small objects like picnic tables. Once you
feel confident on the grass or in the gym, progressively move to
harder surfaces. Do not go straight to asphalt. Instead, find hard
surfaces that are smoother like wood floors or tennis courts. When
moving onto such surfaces you will immediately feel all the points
of contact. This is often a rude awakening as to how good your
technique really is.
In order to master your technique there are several things to
remember. First, do not over train. It is too easy to permanently
damage your back by rolling repetitively with the wrong technique.
Second, you must land properly. This means landing with both feet
on the ground, your knees bent no more than 90 degrees, your body
leaning forward prepared to roll, and your hands out in front of
you. Remember not to put too much weight on your hands. When
placing them on the ground in front of you, keep your elbows bent
and only allow your hands to touch briefly. They are meant to guide
your body into the roll, not to absorb impact. Next, look back and
turn your head away from the shoulder you are rolling over. Do not
let any of the bones in your shoulder touch the ground. The first
point of contact on your back should be just under the top of the
scapula.. If you have turned your body correctly going into the
roll the next point of contact will be the muscles above the hip on
the opposite side of the back. In summary, you will roll only on
the muscles going diagonally across the spine. When coming out of
the roll you can use the arm and leg opposite to the shoulder you
rolled over to push off the ground. Distributing the impact as
evenly as possible is extremely important. You should not feel
excess pain on any one point of your body.
Like any technique in parkour it is essential to stay safe by
building up your skills slowly. As said before, there are always
alternatives to jumping if you have not mastered the roll. It is
entirely possible to practice parkour quickly efficiently and
safely without ever rolling once. However, knowing the technique
will most definitely improve your parkour. Be smart and safe, and
do not jump from heights until you are completely ready.
