Adventure
Sports: Bungee Jumping
Bungee jumping is an adventurous sport where
the participant jumps from a great height while he
is connected to a large rubber rope. The jump can be
made from the top of a tall building, bridge or
crane. To bring in more adrenalin rush, jump can be
made from a moving object like helicopter or a hot
air balloon.
Bungee word was developed in 1930, which meant
rubber eraser. The idea originated from dwellers of
the Pentecost Island, who used to tie vines to their
ankles and jumped from tall wooden platforms. The
vine was substituted by elastic cord. Members of the
Dangerous Sports club made the first official bungee
jumping on April 1, 1979 from the Clifton Suspension
Bridge in Bristol. Initially they were arrested, but
later on they appeared on television and jumped from
many places including hot air balloon and mobile
cranes, in 1982.
A J Hackett of New Zealand did the first commercial
bungee jumping in 1986, from Auckland's Greenhithe
Bridge. After that he made numerous jumps from
famous monuments like the Eiffel Tower. The first
bungee jumping site was laid in Queenstown, New
Zealand, on the Kawarau Bridge.
The rubber rope absorbs the complete energy of the
fall and when the rope snaps back, the jumper flies
in the upward direction. The process of oscillation
continues until all energy is utilized. The rubber
rope is covered with cloth and has hooks on both the
end. It is a specially designed braided shock cord.
A tough outer cover encloses many latex strands. The
function of the tough outer cover is to provide
durability. Some consider using unbraided cords
without the tough outer cover, which delivers a
longer and softer bounce. Commercial operators are
forced to use body harness to ensure safety in case
of accidents.
Variations to traditionally bungee jumping are
catapult, twin tower, bungee running and bungee
trampoline. In catapult, the jumper is placed on the
ground and the cord is stretched, usually with the
help of a crane, and then the jumper is released and
he goes shooting up in the air. Twin towers employs
two oblique cords. Bungee running, as the name
suggests involves running and not jumping. The rope
is attached to the participant and he runs as far as
possible on an inflatable surface. The point maximum
reached is marked with the help of a Velcro-backed
marker, after which the runner gets pulled back to
his initial position. Two or more people are
involved in this and it is more like a running
competition. Bungee Trampoline has a mix of bungee
and trampolining. The body is fitted into a harness
attached to a trampoline, which in turn is attached
to a bungee. When the participant begins to jump he
goes higher than a normal trampoline would.
Bungee jumping has been incorporated in many movies
and video albums. The most famous of all is the
James Bond movie, Golden Eye, which was released in
1995. The movie opens with Bond jumping from a dam
in Russia. The jump was no special effect and was
genuine.
Like other sports, bungee jumping has its share of
possible injuries. The reason for most of them is
human error, along with failure of safety harness,
miscalculation of elasticity of the rope and
improper connection of the cord. Possible injuries
are body entangling with the rope, rope burn,
dislocations, eye trauma, uterine prolapsed, back
injury, pinched fingers and bruises. Jumper's age,
weight, experience, and location should be reviewed
before the jump, as a safety measure.
