Skeletal System Flashcards
How does a warm up improve the performance of our joints and skeleton in sport ?
Increase of blood circulation
increases muscle/joint temperature more freely moveable
increase the amount of synovial fluid in the joint
relax joints and muscles and lessen pain
How does the skeleton adapt to a period of training ?
Bones become denser
Enhanced joint support cartilage more thicker ligaments more resilient
Increased collagen production
Better joint mobility
Example of weight bearing exercise (makes are bones stronger)
Running/jogging
Body weight exercises
Example of non weight bearing exercises
Cycling
Swimming
What is osteoarthritis
Inflation of a synovial joint
Caused by wear and tear over time
Bones rub together and wear away
Pain and stiffness in the joint
Reduction in the amount of normal cartilage tissues
How does exercise help osteoarthritis?
Nourishes the cartilage
Reduces friction between the bones
Stretching lengthens the ligaments improving the range of movement at the joint
Lubricators the joint
What is osteoporosis ?
Weakening of the bone
Caused by loss of calcium and vitamin D
As you get older bones loses mineral density becoming brittle fragile and more likely to break
Why should children not perform resistance training?
Fines are still growing, too much force damages the epiphyseal played which can’t stunt growth
Muscles found at the elbow
Bicep
Tricep
