•
Physical activity stimulates the production of bone tissue to
compensate for the stresses of training.
•
If the intensity is too high, damage and injury of the bone can
occur e.g. shin splints.
•
Reduced stress results in bone weight and strength reduction –
ATROPHY – usually after a lay-off due to injury. It is important
to return to full training slowly, to allow the bones to adapt.

JOINTS
• Joints enable the body to move.
• Joints are the place where 2 bones meet.
• Each type of physical activity will make particular demands on
certain joints
e.g. butterfly swimmers require a wider than natural range of
movement at the shoulder joint – ball and socket.
• Joints are structured for either STRENGTH or MOBILITY:
SHOULDER JOINT
HIP JOINT
Shallow cavity to
allow more
movement but is
less stable
Supports body
weight – is more
stable – less
movement allowed

Good joint mobility is often an essential requirement to good
performance in physical activity and has implications regarding
training programmes.
Joints can be classified according to the amount of movement
they allow:
Information/Discussion
1) IMMOVABLE / FIBROUS JOINTS
Practical Application
These joints are fixed and no movement is possible. Examples are found
in the skull and pelvic girdle – areas of the body where great strength is
required.
Links
2) SLIGHTLY MOVABLE / CARTILAGINOUS JOINTS
Diagram/Table
There are small gaps between the bones at these joints, filled with
CARTILAGE to prevent grinding and enable slight movement. Examples
are found between the vertebrae and between the ribs and sternum.
Activity
3) FREELY MOVABLE / SYNOVIAL JOINTS
Revision
SECTION B

UNIT 1 - Information
The Muscular, Skeletal, Respiratory and Cardiovascular Systems
The majority of joints in the body are synovial – they allow the
greatest range of movement.
The bones are linked by LIGAMENTS.
Information/Discussion
Practical Application
There are 6 types of synovial joint, and each type has its own
characteristic range and type of movement.
They are designed to stop and prevent friction between the moving
bones.
Links
Examples are the shoulder, elbow, hip, knee and ankle joints.
Diagram/Table
Activity
These joints are important for physical activity – they are often put
under a great deal of stress (e.g. the knee), but are so designed to
be robust and withstand pressure.

CARTILAGE
Practical Application

Ligaments are strong, fibrous, non-elastic bands of tissue which
attach bone to bone across a joint.
They control the movement and the stability of the joint.
They hold a joint in place.
They prevent unwanted movements at a joint.
•

•
Activity
Cartilage protects bone.
It is a tough, smooth tissue that covers the end of bones and acts as a
shock absorber.
It reduces friction between the bones.
Cartilage damage may occur over a period of time because of the
constant stress/ impact and twisting/ turning of physical activity.
