Physiological Responses
to Sports Injury

Lack of Function
Pain
Discolouration
Heat
Repair Phase
Remodelling phase
Inflammation
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
defence reaction
, and very much part of the
healing process
.
The Healing process
Inflammatory Response Phase
Swelling
This
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 (
scar
) tissue contains collagen fibres and is moderately fragile. The fibres of collagen are initially randomly arranged, but
over time
and with
careful rehabilitation
, they become
aligned
along the lines of the
external stress
that are placed upon them during both
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
are
ruptured
, allowing blood to
bleed into the areas
and the tissue fluid to gather around the injury site
When the injured area starts to swell, it will
feel painful.
This is due to the swelling
creating pressure on the nerves
surrounding the damaged tissue.
The injured area will show a reduced function or a total inability function because of the pain and swelling.
The
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
the
healing/repair process begins
. This consists of:

•Absorption
of swelling

•Removal
of debris and blood clot

•Growth
of new blood capillaries

•Development
of initial fibrous scar tissue.

After
12 hours,
and for the
first four days
, the cells soon become active and
new capillary blood vessels form
and gradually
grow
to establish a
new circulation
in the area.
