And More |
As we start out for a day of hiking,
climbing or searching we carry
everything we need and more in our
backpacks. We carry the medicine
cabinet, i.e. sunblock, foot powder,
insect repellent, aspirin and a comb. The
kitchen cabinet i.e. food, stove, pots and
pans and snacks. And of course lets not
forget the utility closet i.e. map and
compass. knife, flashlight or candles and
all of the ten essentials. Some of us even
try to carry the kitchen sink, at least
that's what it felt like the last time I lifted
Pat's backpack.
If you properly selected and fit your
backpack this load shouldn't be too hard
to carry. The harness padding should not
be too hard or soft. Standing at the
trailhead a soft harness feels great, but a
few miles down the trail you may wish
for a harder version. A large pack should
also have lift straps to transfer the load to
the hips. And a hipbelt should feel
comfortable but have enough rigidity to
support the load. The three main areas of
your body that help carry this load are
your back, shoulders and hips.
BACK
Eight out of ten Americans between the
ages of 25 and 45, even the most fitness-
minded of us will experience back pain.
It could vary between an annoying ache
or an intense pain, however; when it
comes to back pain it's very difficult to
pinpoint the exact cause. As man has
evolved over the millennia to an upright
posture it has caused the lumbar (or
lower back) to bear most of the weight
of this evolving posture. The fact that
man has been carrying things on his back
since the stone age has led to back
injuries being one of the most common in
the anthropological record.
As climbers, hikers and rescuers we
carry everything we need on our backs
so our risk of back injuries increases. The
three most common problems are disk
injury, joint injury (sprains) and muscle
or soft tissue injury (strains). From your
head to your tail bone your spine consists
of 33 roughly cylindrical bones called
vertebrae. They are separated by fibrous
rings with jelly-like middles called
intervertebral disks. This amazing setup
allows you to bend and rotate from your
neck to your hips. The main disadvantage
is there is no large bone to act as an
anchor, so if one joint or disk gets
injured the whole system goes out of
whack. Soft tissue injury is caused by
injury to the muscles that support your
spine and usually manifest themselves as
aching muscles or muscle spasms.
SHOULDER
Most shoulder injuries consist of
separations, dislocation, subluxation or
tendinitis and bursitis. When you sprain
the ligaments that stabilize the joint
between the shoulder blade and collar
bone you have what is called a
separation. If the ball of the upper arm
bone (humerus) is pushed out of its
socket a dislocation has occurred. A
subluxation is an incomplete dislocation.
However, the shoulder injuries that affect
most climbers and hikers are tendinitis
and bursitis. Tendinitis is an inflammation
of the muscles attached to the bone .
Bursitis is an inflammation of the
lubricating surfaces of the joint.
The vulnerability of the shoulder to injury
comes from its design which sacrifices
mobility for stability. the shoulder is
formed by ball and socket joint. The ball
is the head of the humerus bone and the
socket formed by the shoulder blade and
the collar bone. All this is held in place
by three stringy muscles known as the
rotator cuff. Activities such as climbing
that require you to have your arms over
your head can lead to inflammation of
these muscles.
HIP
The problems with the hip mirror the
problems with the shoulder; both are ball
and socket joints and both can be
dislocated, sprained and strained.
