This is a common bone disorder that is caused by low
bone density and deterioration of bone tissue. This
severely weakens the bone, making it prone to
fractures. Bones in the hip, spine and wrist joints are
commonly affected, although condition can occur in any
bone. This disorder can lead to a sedentary lifestyle. It
occurs when bones lose an excessive amount of their
protein and mineral content, particularly calcium. Over
time, bone mass, and therefore bone strength, is
decreased. As a result, bones become fragile and break
easily. Even a sneeze or a sudden movement may be
enough to break a bone in someone with severe
osteoporosis. Bones are at their thickest and strongest
in early adult life and are constantly renewed and
repaired through a process called bone turnover.
However, as you age, this process is no longer balanced
and bone loss increases. This means bone is very slowly
broken down over time and your bones become
less dense as you get older. This leads to the bone
becoming weaker and more likely to fracture.…read more

Growth Place Disorder.
Growth plate injuries are fractures and are caused by a
sudden force travelling through the bone in a
competitive, contact and impact activities such a
football, rugby, hockey and basketball. However injuries
in young performers can also result from repetitive
practice of specific skills such as a young tennis player
who spends too much time continually trying to perfect
something. One-third of all growth plate injuries occur
in competitive sports such as football, basketball, or
gymnastics, while about 20 percent of growth plate
fractures occur as a result of recreational activities such
as biking, sledding, skiing, or skateboarding. Fractures
can result from a single traumatic event, such as a fall or
automobile accident, or from chronic stress and
overuse. Most growth plate fractures occur in the long
bones of the fingers (phalanges) and the outer bone of
the forearm (radius). They are also common in the
lower bones of the leg (the tibia and fibula).…read more

This is a degenerative disease caused by a loss of
articular cartilage at the ends of long bones in a
joint. It causes pail, swelling and reduced motion.
Articular cartilage covers the end of long bones to
act to absorb shock, release synovial fluid and
prevent friction between bones during movement.
It commonly affects weight bearing joints, such as
the knee and hops. Repetitive use of these joint
through sport and physical activity causes wear
and tear on the articular cartilage, which gives rise
to joint pain and swelling. This articular cartilage
begins to deteriorate and in advanced cases, there
is a total loss of the cartilaginous cushion. This
causes friction between bones and can lead to new
bone spurs being formed around the joint giving
considerable pain and severely limiting joint and
flexibility and movement.…read more

Joint Stability.
Joint stability is a very important factor in lifelong
involvement in physical activity because a stable
joint is able to be constantly compressed and
stretched without injury. Deeper joints that have a
larger surface area of connecting bone are the most
stable types of joint. The ball and socket joint of the
hip is particularly stable for this reason
compounded by the fact that weight bearing
pushing the head of the femur further into the deep
socket of the acetabulum. Ligaments in joints make
it more stable, there are the four
These work to limit mobility of flexibility. But these
can be a disadvantages as they are not very elastic
they can be prone to snapping. The third influence
on joint stability would be the location of the
muscle and the tone surrounding it. Muscle tone is
important because it helps to keep the tendons
around a joint tight adding stability to the joint.…read more

Main Concern
in Contact
OSTEOPOROSIS: By playing contact sports, you are putting
yourself in danger of being tackled firmly for example in
rugby, you are more likely to be hurt as the games are
rough and dangerous. If a player in this sport had brittle
bones their bones would be fragile and bones would be
broken easily.
OSTEOARTHRITIS: There is some evidence that suggests
that injuries sustained when you're younger can lead to
osteoarthritis in later life. By playing a sport where you are
constantly in danger of being tackled by another player
harshly then then you are more likely to gain injuries from
it, and if you are more likely to gain osteoarthritis from this,
you are putting yourself in danger.
JOINT STABILITY: Large forces exerted on a joint, such a
impact sports can lead to ligament damage and dislocation
of less stable joints. The knee and ankle joints are
particularly at risk of ligament damage, while the shallow
joint of the shoulder makes it susceptible to dislocation.…read more

Potential risks, re
participation in
Contact sports.
Excessive load on the body. The tissues of the body are capable
of withstanding considerable stress: more than three times your
weight can go through the body even when jogging slowly. But
tissues that aren't accustomed to such forces won't have
adapted to withstand them and are likely to be injured when
they're applied. When deciding how often, how hard and for
how long to exercise, you need to consider the impact on your
muscles and joints. By playing contact sports over 5 times a week
you are putting pressure on your joints and tissues (which can
strain easily) which they cannot withstand, so injuries will be
more common. If you begin playing rugby or any contact sport
and play several hours in an attempt to improve rapidly, you are
setting yourself up for an overuse injury. In contact sports, the
chances of injury is much higher because your safety is
technically in other peoples hands. This is because you are trying
to do too much and do not allow your body adequate time to
recover. As a beginner, you may also have poor technique which
may predispose you to tennis elbow.…read more
