6
Q
What is injury prevention & risk management?
A
- All sport has a inherent risk associated with it
- There is a less than 50% chance injury will occur once you enter the playing arena
- Many sport injuries are accidental with no preventable intervention

26
What is foreseeability?
- The relationship between the duty or standard of conduct & the actual injuries or damages resulting
- how likely it was that someone could have predicted the consequences of their actions
- i.e., if an instructor allows 5 people on a trampoline it is foreseeable that injury might occur
27
What is in loco parents?
- A person who stands in place of the parent, commonly used with respect to making decisions in dealing with minors under the age of 18
- A coach does not stand in loco parentis, especially in terms of medical decisions
28
What is public policy theory?
- It is better to compensate an innocent victim at the expense of a wrongdoer even if accidental
29
What is res ipsa loquitor?
- the shifting of onus, so that the defendant must disprove negligence
- presumed to be negligent if he/she had exclusive control of whatever caused the injury even though there is no specific evidence of an act of negligence, & without negligence the accident would not have happened

38
How does proper conditioning prevent injury?
- properly graded conditioning programs will result in changes of both, structure & function of the body systems & tissues
39
What changes occur with proper conditioning?
- Connective tissue structures will become thicker, denser & stronger providing for increased stability of joints
- Muscle cross sectional area will increase leading to increase in strength & work capacity
- Bone will increase in density when positively stressed
40
What are the 3 principles of proper conditioning & injury prevention? And what format do they follow?
- cardio respiratory fitness, muscular strength & endurance, flexibility
- follows the FITT principle
41
What are 3 components of muscular fitness?
- strength
- endurance
- overload principle
42
What is strength?
- Strength: The ability of a muscle or muscle group to exert force against a maximum resistance for a single repetition
43
What is muscular endurance?
- Endurance: The ability of a muscle or group to repeatedly exert force against a resistance over a given period of time
44
What is the overload principle?
- Overload Principle: Muscles must be stressed to higher levels at each workout for change in strength or endurance is to be achieved
45
What is isotonic?
- Involves Concentric & Eccentric muscle contraction
- the resistance is fixed & the ability to perform work is limited by the muscles weak point within the active ROM
46
What is isometric contraction?
- a contraction without movement (holding weight)
- Strength gains are limited to a given angle with overlap into the other angle by about 30%
- Time consuming as each contraction must be held for 8-10 seconds
47
What is a warmup? Why is it important?
- The function is to prepare the body for safe participation in sport
- Warm-up is intended to:
- Increase heart rate & core temperature
- i.e., Static stretching 3-4 reps for 20-30 seconds hold, General & specific body movements
48
What is a cooldown?
- Main function is to restore body to resting state
- I.e., light cardio, general static stretch, replace fluid stores
49
What does a good program look like during the conditioning season?
- A good conditioning program should reflect the sport demands & the time period the sport is played in
50
What are the 4 seasons in the conditioning season?
- post season
- off season
- pre season
- in season
51
What is the post season portion of the conditioning seasons?
- The time period varies in length generally speaking 2-3 weeks, though it may go directly into the off season time
- recognized for physical & mental recovery from injuries suffered during the season or from any surgery performed
52
What is the off season portion of the conditioning seasons?
- used for psychological rest
- The athlete is encouraged to participate in recreational activities different from their sport, but still requiring physical exertion
- The main emphasis is that the athlete does not become de-conditioned nor does he/she become overweight etc
53
What is the pre season portion of the conditioning seasons?
- This period should begin approximately 2-3 months prior to the season
- The main emphasis being on restoring all components of fitness to participation levels & should focus on the following:
- cardio respiratory endurance, muscular strength/endurance, flexibility, sport related skills & skill development
54
What is the in season portion of the conditioning seasons?
- focus is to maintain the components of fitness developed in the pre-season
- participate in conditioning activities at least 2 but not more than 3 times per week
- intensity should be at least 80% of what the athlete had been doing in their pre season workouts
55
What are the 3 functions of nutrition?
- Provide fuel & energy - i.e., carbohydrates
- Build, maintain & repair tissue - i.e., protein
- Regulate body processes - i.e., vitamins & minerals
56
Why is a balanced diet important?
- All foods must be consumed in balance to provide proper levels of nutrients to the body
- Canada’s Food Guide recommends:

- Hydration is key (500-750 ml of liquid)
61
How do we gain & lose weight?
- Weight Gain: Increased energy in & decreased energy out
- Weight Loss: Decreased energy in & increased energy out
- Note that 3500 calories = 1 pound of fat
62
How does protective equipment help prevent injury?
- The effect of an impact force on the human body is dependant upon the magnitude & duration of that force & the area of the body to which that force is applied
- Protect the body from impact forces by any or all of the following:
- Absorption
- Deflection
- Dissipation
63
What are 2 forces protective equipment can protect you from?
- High Velocity Low Mass Forces: I.e., Being hit by a baseball, hockey puck, bat.
- Result: concentrated force focal injury
- Low Velocity High Mass Force: I.e., Being hit by an opponent ;or hitting the ground
- Result: generally a diffuse injury as the force is spread over a large area
64
What are 4 functions to know protective equipment will be effective?
- include an absorptive phase between impact & rebound
- distribute impact to strong parts of the body
- prevent abrasions and lacerations
- be heat and flame resistant
