Skeletal: Additional factors

Question 1

Arthiritis

Answer 1

Arthritis is a condition where there is inflammation in a synovial joint.

This inflammation causes pain and stiffness

Caused by general wear and tear
over time, reducing the normal
amount of cartilage. Bones
therefore rub together.

Regular exercise can prevent arthritis. As we exercise, our joints produce more synovial fluid.

This increase causes: Lubrication and reduction in friction

Question 2

Osteoporosis

Answer 2

Osteoporosis is the weakening of bones caused by a loss in calcium, or a lack
of vitamin D. As you get older, your bones lose their mineral density and
naturally become brittle, fragile and more likely to break under stress.

Exercise can help prevent osteoporosis by increasing the uptake of minerals
within the bone - resulting in an increase in bone mineral density.

Question 3

Age

Answer 3

The skeletal system is a living tissue that is constantly growing and repairing
itself. Generally, exercise and sport will benefit you.

However, we have to be aware of resistance training (weight training) at a
young age.

As bones are still growing, the forces applied through the bone damage
the epiphyseal heads. Damage to these plates during childhood and puberty
results in stunted bone growth.
