Biomechanics Of Injury

Question 1

What is an injury

Answer 1

Results in absence from scheduled activities for at least one training or game

Question 2

Importance of player availability

Answer 2

Win percentage goes up with more first teamers available

Question 3

When does an injury occur

Answer 3

When the tissue experience force that exceeds their capacity to tolerate force

Question 4

Factors that influence loading of a tissue

Answer 4

Magnitude
Duration
Frequency
Direction of loading
Age and health
Nutrition and hydration
Previous injury
Environment

Question 5

Factors that influence load tolerance of a tissue

Answer 5

Tissue type
Age and health
Previous injury
Nutrition and hydration
Genetics
Activity level
Environmental
Mechanical loading history

Question 6

Types of force application

Answer 6

Tensión
Compression
Shear
Torsion- twist

Question 7

How do tissue react to forces

Answer 7

Stress strain curve, toe , elastic ,plastic ,failure

Question 8

Young’s modulus

Answer 8

The modulus of elasticity the measure of the stiffness of a material

Question 9

Types of injury

Answer 9

Acute and chronic

Question 10

Acute injuries occur

Answer 10

Trauma, fracture sprain strain

Question 11

Chronic injuries occur

Answer 11

Repetitive micro traumas , overuse over loading

Question 12

Signs of acute injury

Answer 12

Sudden onset of pain
Severe pain
Bleeding
Discolouration or bruising
Swelling tenderness
Inability to weight bear

Question 13

Signs of chronic injury

Answer 13

Swelling at site
Dull uncomfortable pain
Pain when active
Lack of full rom

Question 14

Risk factors of tissue injury

Answer 14

Excess force
Biomechanics
Nutrition
Female
Strength
Aerobic fitness
Fatique

Question 15

Exercise definition

Answer 15

The systematic application of force to the human body

Question 16

What can measure the force or stress on an athlete

Answer 16

GPS

Question 17

What is training load

Answer 17

Is a measure of the amount of force placed on an athlete from training

Question 18

Types of training load

Answer 18

External load lifted sets x reps x weight
internal load RPE HEART RATE

Question 19

Why do we measure training load

Answer 19

Train too much increases injury risk
Train too little decreases performance
Train too little increases injury risk
Acute spikes increase injury risk

Question 20

The optimal amount of training

Answer 20

Is between acute overload and overreaching

Question 21

The principle of training states

Answer 21

That whereas regular physical training results in several physiological adaptations that enhance athletic performance stopping or markedly reducing training induced a partial or complete reversal of these adaptations compromising performance

Question 22

Acute chronic workload ratio

Answer 22

Based on the fitness fatigue model, this weeks workload relative to the last four weeks, fitness should be greater than fatigue

Question 23

Periodisation

Answer 23

Micro cycles md+-1/2/3?etc

Question 24

Fatigue is

Answer 24

The failure to maintain the required or expected force or power output

Question 25

Two types of fatigue

Answer 25

Central fatigue and peripheral fatigue

Question 26

Symptoms of fatigue

Answer 26

Performance
Fatigue
Physiology
Immune function
Mood
Blood
Sleep
Gasto intestinal
