Physiological responses to injuriesNetball:
Ankle sprains
Shin sprints
Patellar tendinitis
Rotator cuff injuries
Dislocations
Bruising
Fractures
Injuries mostly caused in netball are not impacted. This means that they are mostly caused by the players
themselves with things such as twists and mis turn.
Learning aim-
1. Describe the distinct stages of tissue and bone injury
2. Explain the similarities and differences between the healing of bone and tissue injuries
3. Explain the factors affecting the healing process of an injury
Body's response to a tissue injury (muscles, organs, connective tissues- (tendons & ligaments), cartilage, skin)
The body responds to a tissue injury almost immediately.
There are 3 places of response (flow chart):
Phase 1= the inflammatory stage
Phase 2= tissue formation
Phase 3= the remodelling phase
Phase 1- The inflammatory stage
This phase is an essential part of tissue repair.
It happens quickly following an injury (0-3 days), peaks after 24-72 hours, and can last for a few weeks.
It is the protective periods which involves vascular and cellular changes through chemical release.
These include pain, swelling, vasodilation as well as the removal of cell debris.
Without the inflammatory stage, the healing process will not occur.
Phase 2- Tissue formation
This is known as “proliferation.”
It is important for generating material and has 2 main events.
Angiogenesis- firstly, there are development of new capillaries to promote healing around the site of the injury.
At this stage, the supportive network develops into scar tissue randomly arranged (fibre called type 111
collagen), which is weaker than uninjured tissue.
This stage can last from 24 hours to 6 months (peaking in 2-3 weeks).
Fibroblastic repair- secondly, cells (fibroblasts) start to build a new supportive network to stabilize the site of the
injury.
