Physiological responses to Sports Injury
Transcript of Physiological responses to Sports Injury
to Sports Injury
Lack of Function
is the sequence of reactions which take place in the
body in response to injury
. Inflammation can result not just from physical injury, but also thermal injury, electrical injury, chemical injury, infection or immune reactions.
The inflammatory process is considered a
, and very much part of the
The Healing process
Inflammatory Response Phase
stage of soft-tissue healing
is when the first
structural repair work begins
, with the development of a
network of capillaries and lymphatics
. This means that the injury site now has improved
circulation and drainage.
Typically by the
fourth or fifth day
, a weak mesh of
fibrous connective tissue
has been laid down at the injury site. At this stage, the newly formed tissue is
fragile, vascular and vulnerable to re-injury
The repairing (
) tissue contains collagen fibres and is moderately fragile. The fibres of collagen are initially randomly arranged, but
, they become

normal activities and rehabilitation exercises
The injured area will usually look red because the
blood vessels surrounding the site dilate
, which also has the effect of making the injured area feel...
The swelling occurs because the
surrounding blood vessels

bleed into the areas
and the tissue fluid to gather around the injury site
When the injured area starts to swell, it will

surrounding the damaged tissue.
The injured area will show a reduced function or a total inability function because of the pain and swelling.
body's clotting mechanism seals the end
of the torn blood vessels so that
further blood plasma cannot escape into the surrounding tissues
. As the
immediate effects of injury subside
healing/repair process begins
. This consists of:
of debris and blood clot
of new blood capillaries
of initial fibrous scar tissue.
and for the
first four days
, the cells soon become active and
new capillary blood vessels form
to establish a
