Skeletal System
- Injuries
- Skeletal System absorbs impacts and collisions so can lead to injury
- Some injuries are chronic, which means they develop over a period of
time and usually caused by stress
- Caused by training too hard, poor technique, poor footwear and lack of recovery time
- Chronic injury
- Occur due to repeated powerful muscle movement
- Injuries should be treated by applying an
ice-pack and resting for several weeks
- Physiotherapy and possibly cortisone injections may be
needed to treat these conditions
- Shin splints
- Shin splints are pains in the lower leg, caused by
continuous stress over a long period of time
- Either the tendons around the tibia become inflamed, or
'stress fractured' develop
- Stress fractures are cracks along the length of the bone
- Shin splints should be treated with ice packs and plenty
of rest. Cushioned footwear and special insoles can help
to prevent the injury returning
- Acute injuries
- Sprained/twisted ankle
- Occur suddenly during an activity
- Sprains
- They involve ligaments rather than muscles and tendons
- Sprains occur when the ligaments at the joints get
stretched and torn
- A sharp twist of the foot can give you a sprained or twisted ankle. Severe
sprains result in torn ligaments
- Fractures
- Simple
- Means that the bone is cracked but the shin is not broken
- Compound
- Means that the skin is broken and the bone is sticking out
- Caused by violent impacts, most common in contact sports like rugby
and sports where there is a risk of falling from height or at spped
- Fractures are difficult to prevent as they cause by sudden and unexpected events or
incidents. Using correct technique and playing by the rules can help reduce the risk
- Fractures should be treated by immobilizing the injured area with a splint or sling
- The casualty should not be moved until a ambulance arrives unless necessary
- Fractures lead to; bruising, swelling, nerve damage(pain), limbs in area become immobile
- Dislocation
- Occurs when a bone is pulled or twisted out of plave at a joint
- When a dislocation is the shoulder occurs the humerus is pulled out of the socket on the scapula
- Very painful, require hospital treatment to move the bone back into position. The
ligaments and tissue around the joint can take a long time to recover
- Short and Long term effects of exercise
- Joints have to work harder
- Increase production of synovial fluid, which is secreted around the synovial joints to
increase range and movement ease
- Weight-bearing exercise can help to maintain bone density and strength
- Both aerobic exercise and weight training, but must be weight bearing to increase
bone strength
- Stringer denser bones are better at carrying weight and are more resistant to injury
