Principles of Injury Prevention Flashcards
Why do we get injured
Humans perform range of tasks.
Athletes push limits of body.
Exceed limits —-> Injury.
Definition of injury
Bodily damage caused by a transfer of energy that exceeded the body’s ability to maintain its structural/functional integrity.
Traumatic injuries
One off overload of the system
Often due to impact mechanism
Acute
First injury episode
Chronic
Recurrence of previous injury
Overuse injuries
Repeated loading the system
Damage builds up over time
Symptoms appear gradually
Load not of excessive magnitude can cause failure
Risk factor
Any attribute, characteristic or exposure of an individual that increases the likelihood of developing a disease or injury
Intrinsic risk factors
Previous injury
Genetic factors
Malalignment
Muscle imbalance
Leg length discrepancy
Lack of flexibility
Sex, size & body composition
Extrinsic risk factors
Environmental conditions
- Heat
- Cold
- Humidity
- Dryness
- Altitude
- Wind
Surface
- Uneven
- Cambered
- Hard
Equipment
- Inappropriate shoes
- Racket
Sport - modifiable by rule changes
Quantification of injury
Injury definition
Injury severity
Reporting injury data
Injury burden
Injury classification
Injury defintion
Medical attention
Time loss injury
Injury severity
Usually defined by time loss period
Slight - 0-1 days Minimal - 2-3 days Mild - 4-7 days Moderate - 2-28 days Severe - >28 days
Reporting injury data
Absolute numbers
Proportions
Incidence rate
Injury burden =
Injury incidence rate x Average severity
