Classification of joints

Classification of Joints: Overview

  • Joints are points where two or more bones come together.
  • They play a crucial role in movement and provide support to our body.
  • There are three main types of joints, including fibrous, cartilaginous, and synovial joints.

Fibrous Joints

  • Fibrous joints are joints that are held together by dense connective tissue.
  • They do not allow for much movement and are found where bones need to be tightly joined such as in the skull.

Cartilaginous Joints

  • Cartilaginous joints are the bones that are joined together by cartilage.
  • They allow for a small amount of movement. Examples include the joints between the vertebrae in the spine.

Synovial Joints

  • Synovial joints are the most common type of joint, and they allow a wide range of movements.
  • They are surrounded by a fluid-filled capsule that lubricates the joint and allows smooth movement.

Classification of Synovial Joints

  • There are six main types of synovial joints: pivot, hinge, saddle, plane, condyloid, and ball and socket.
  • The classification depends on the shape of the bones and their range of movement.

Role of Joints in Sport Performance

  • Understanding the classification of joints is essential for athletes to maximise their sport performance and to minimise the risk of injury.
  • Different sports require the use of different types of joints and joint movements. For instance, a footballer depends primarily on their hinge joints (e.g., knees and elbows) and ball and socket joints (e.g., hip and shoulder) to kick a ball or throw a pass.

Joints and Training

  • Knowing which joints are used in a particular sport can help in designing more effective training programmes.
  • This can help to strengthen the muscles around those joints, to enhance performance and prevent injuries.
  • For instance, a swimmer would benefit from exercises that increase the flexibility and strength in their shoulder joints (ball and socket joint).

Joints and Musculoskeletal Knowledge

  • A thorough understanding of the workings of different joints can contribute to improved performance and longevity in a sporting career.
  • It can also contribute to the development of better training methods and equipment that can safeguard against injury.
