Is this weight bearing or non weight bearing? • What is a long term benefit that this type of activity provides to the skeletal system?
Lesson Objectives • knowledge of the different sports injuries that can happen to the skeletal system • Knowledge of exercise and the effects it has on the skeletal system • Knowledge of diet and the effects it has on the skeletal system
Fractures • Compound • Greenstick • Simple • Stress http://www.youtube.com/watch?v=9QTCBrefXso
Fractures • Compound: Broken bone that comes through the skin • Greenstick: Break only part way across the bone • Simple: Fracture in one line, no displacement • Stress: Overuse injuries usually in weight bearing areas such as lower leg (shin splints)
Joint Injuries • Tennis & Golfers Elbow • Dislocations • Sprains • Torn Cartilage
Tennis & Golfers Elbow This is an injury cause by overuse to the tendons at the elbow joint. • Dislocation This is when a bone is forced out of its normal position as a result of a hard impact causing the blood to be displaced. • Sprain This is a damaged ligament, commonly caused by a twisting of the ankle • Torn Cartilage Cartilage is a protective substance that covers the end of a bone. Tearing can be caused by twisting at a joint e.g. the knee
Treatment - RICE • Rest • Ice • Compression • Elevation
