Chapter 3- Part 1 Flashcards
What are lifestyle diseases?
Diseases related to decreased physical activity, such as heart disease, strokes and type 2 diabetes
What are the costs of sport-related injuries?
Healthcare for treatment, insurance costs, time and productivity lost, long term physical damage and equipment costs for rehab
What are acute injuries?
A sudden injury which occur without warning, whereby pain and loss of function are experienced immediately, such as a hamstring strain
What are the 2 types of acute injuries?
Direct and indirect
What are direct injuries?
The result of an external force, such as a collision with another person or a direct blow from equipment
What are indirect injuries?
A sudden change in direction or intensity, where the force required is greater than the load the muscle or ligament can sustain
What is the damage that direct or indirect injuries can cause?
Minor Damage- Bruises
Major Damage- Broken Bones
How are ligaments damaged?
When joints move further than the ideal physiological range, resulting in a sprain
What are grade 1, 2 and 3 ligament sprains?
Grade 1 sprain = Mild damage to a ligament
Grade 2 sprain = Partial tear of a ligament
Grade 3 sprain = Complete tear of the ligament
When are muscles usually injured?
Under eccentric loading or plyometric movement, because almost twice the force goes through a lengthening muscle compared to a shortening one, causing a strain
What are grade 1, 2 and 3 muscle strains?
Grade 1 strain = Damage to less than 5 per cent of muscle fibres
Grade 2 strain = More extensive damage than grade 1, but muscle isn’t completely ruptured
Grade 3 strain = Muscle is completely ruptured
What can help to reduce the recovery time of injuries?
Immediate first aid
What are chronic injuries?
A recurring injury that presents itself again in response to a prolonged weakness or insufficient rehabilitation after an initial injury
What do overuse injuries come from?
The repetitive performance of some type of movement, such as elbow tendonitis from tennis
What are some factors which can lead to overuse injuries?
Repetitive nature of an activity, inadequate footwear, inappropriate training surface or insufficient recovery time
