Flexibility: Anatomical Range of Movement of a Joint or Series of Joints

  • Flexibility is the range of movement in a joint or series of joints and muscle length that induces motion.
  • Flexibility varies between individuals and can be increased to some extent by exercise, with stretching being a common exercise component.
  • Limberness is the condition of having superior flexibility, which is also called being flexible.
  • Joints in the human body are surrounded by synovial membranes and articular cartilage, which cover, cushion, and nourish them.
  • Ligaments are composed of two different tissues: white and yellow. The white fibrous tissues are not stretchy, while the yellow elastic tissue can be stretched considerably and return to its original length.
  • Tendons are not elastic and are categorized as a connective tissue. The areolar tissue is permeable and is extensively distributed throughout the body.
  • Muscle tissue is made of stretchy material and is arranged in bundles of parallel fibres.
  • Stretch receptors have two parts: spindle cells and Golgi tendons.
  • Flexibility is improved by stretching, and force applied to the body must be held just beyond a feeling of pain and needs to be held for at least ten seconds.
  • Dynamic flexibility is classified as the ability to complete a full range of motion of a joint.
  • Ballistic stretching prevents lengthening of tissues and should only be performed when the body is very warm; otherwise, it can lead to injury.
  • Each individual is born with a particular range of motion for each joint in their body.
