Preventing Sports Injuries Flashcards
What does a warm-up consist of?
Gradual increase in intensity in physical activity, joint mobility exercise and stretching
Why is a warm-up important?
Because it brings the body to a condition at which it safely responds to nerve signals for quick and efficient action
What is the purpose of dynamic exercises in a warm-up?
Take the joints to a new range of motion causing the muscles to be stretch dynamically
When are dynamic exercises usually completed?
After a comprehensive warm-up and immediately prior to the activity
What is SPIED factor?
Specificity of exercise, participants’ energy levels, intensity of exercises, environmental conditions, duration of exercise
What is the purpose of a cool down?
Slowly decreases heart rate to resting level, aids lactic acid removal and prevents blood pooling
What should a cool down consist of and how long should it last?
Low intensity exercises and static stretching of major muscle groups, 5-30 minutes
What is the purpose of stretching?
To lengthen muscle and tendon tissues to increase the range of motion at a joint
What does stretching achieve?
- Lengthens muscles/tendons
- Reduces muscle tension
- Helps coordination
- Develops proprioception
- Reduces likelihood of injuries
- Promotes circulation
How long should stretches be held for?
20-30 seconds
What does static stretching involve?
Holding a position of near maximum stretch for up to 30 seconds and repeating 3 times
When is static stretching most effective?
Post exercise when the body’s temperature is raised
What are examples of stretches that should be avoided?
- Stretches on the spine
- Unsupported side bending
- Body weight on the neck
- Neck circling
- Hurdlers stretch
- Deep knee bends
- Body weight on knees or ankles
What does proprioceptive neuromuscular facilitation (PNF) stretching involve?
Contracting a stretch muscle for 5-10 seconds against resistance (isometric contraction), then relaxing and stretching the muscle further
What is the most common type of ballistic stretching and why should it be avoided?
Bounce stretching, i.e. using body weight to force the joint angle to increase. Should be avoided because it increases risk of tearing the muscle or tendon
