Q

What do you do to prescribe physical activity?

A

Make SMART Goals & use FITT Principle
SMART
- specific
- measurable
- attainable
- relevant
- time-based

FITT
- frequency: how often you exercise
- intensity: how intense/vigorous
- time: how long
- type: what kind of exercise/modality

ex. lift weights 4x per week

Q

Important point to remember about specificity

A

It does not mean exclusivity
- focusing on specific outcomes still requires a balanced approach
- all movement patterns/whole body approaches should be considered

Q

How does progressive overload apply to exercise prescription?

A

Linked to adaptation

Q

Accomodation

A

Decreased response to a continued stimulus
- If we do not increase the stimulus (more than the body is used to) accomodation will take place

Q

Reversible?

Training and Detraining Trend

A

Longer periods of detraining will result in:
- greater losses
- longer periods of retraining

Retraining
- faster we are able to get back into training routines, the better the outcome

Q

Creating PA Programs

A
  1. Explore initial expectations and exercise objectives
  2. Help each client set personalized and realistic goals
  3. Provide feedback and monitor goals
  4. Use rewards and incentives (intrinsic is best)
  5. Use problem solving to overcome obstacles
  6. Promote long-term adherence

Q

Adaptation

A

What happens in the body afterwards
- linked to goal and how we specifically design our exercise stimulus

18
Q

Supercompensation

A

Explains how we progress over time and adapt to exercise (improvement)
Linked to:
- acute training load (exercise stimulus)
- recovery
- timing of subsequent exercise stimulus

19
Q

Over time if we accumulate these supercompensations we will…

A

Elevate fitness levels

20
Q

When should you time your next workout?

A

Peak of supercompensation

21
Q

Components of a training program

A
  • warm-up
  • cool-down
  • flexibility
  • aerobic
  • resistance/strength
22
Q

Why is warm up important?

A
  • increase body temperature and blood flow to muscles
  • reduce injury risk
  • improve mental focus/preparation
23
Q

Why is cool-down important?

A
  • reduce injury/risk of adverse event
24
Q

Characteristics of a good warm-up

A
  • dynamic
  • rythmic and continuous
  • elevates core and muscle temperature
  • occurs approx 10 min prior to athletic competition
  • lasts approx 10-20% of planned workout time
  • primarily calisthenics
  • includes total body
  • progressive (start slow & easy and progress to quicker)
  • include sport-specific drills/movements at the end
25
Q

Characteristics of good cool down

A
  • gradual
  • cool the body’s temperature
  • similiar duration as warm-up (10% of workout time)
  • include static stretching
26
Q

ACSM Guidelines - Aerobic

A

FITT Principle

Frequency
-greater than or equal to 3-5 times per week
Intensity
- moderate and/or vigorous intensity
- build exercise tolerance
Time
- 30-60 min/day for a total of 150 min/wk
- accumulation in 10 min bouts is ok
Type
- habitual, involving major muscle groups, rythmic
Minimizing Sedentary Behaviour
- increase step count by 2000/day until greater than 7000/day
- can be performed in one continuous session or in bouts of 10 minutes or longer each day

27
Q

What does “threshold for increasing aerobic fitness” mean?

A

Minimal level of intensity of stimulus that we need in order to experience benefits - progressive overload

28
Q

Cardiorespiratory Fitness Based On…

A

Intensity, Duration, and Frequency of Exercise

29
Q

What is the mode of training of cardiorespiratory fitness?

A

Any activity that:
- uses large muscle groups
- is rythmic and aerobic in nature
- can be maintained continuously

ex. jogging, cycling, swimming

30
Q

HITT

A

Continuous work broken up with periods of increased intensity
- bouts last about 15sec-4min
- may be better for aerobic fitness improvements (improving VO2 max)

31
Q

Absolute vs Relative Intensity

A

Absolute - workload
Relative intensity - % of maximum
- amount of work being done can be different but the intensity is perceived to be the same
eg. heart rate of olympic athlete higher than regular individual but are both working at 95% maximum –> percieved to be the same intensity

32
Q

Examples of HITT

A

Sprint approaches
- 4-5 bouts
- 30 seconds of all out sprint
- 4 min recovery between bouts
- total high intensity active time = 2-3 min
- total workout = 20 min

Longer duration approaches
- 4 x 4 approach
- 4 bouts of 4 minutes at high intensity (85-95% HRmax)
- 3 minutes of rest between bouts
- toal high intensity active time = 16 min
- total workout = 25 min

33
Q

Benefits of HIIT

A
  • enjoyment
  • intensity achieved
  • health outcomes
  • fitness outcomes (improving cardiorespiratory fitness & delaying anaerobic thresholds)
  • well tolerated
  • time efficient
34
Q

Negatives of HIIT

A
  • adverse event risk
  • percieved intensity/difficulty
35
Q

ACSM Guidelines - Resistance

A

Frequency
- each major muscle group 2-3x per week
Intensity
- 60-70% 1RM for novice and intermediate exercisers
- >80% for advanced strength trainers
- 40-50% for elderly or previously sedentary exercisers
Time
- no specific recommendation
Type
-whole body, major muscle groups
- variety of equipment & body weight
Volume (sets/reps)
- 8-20 reps (depends on goal/skill/fitness level)
- 2-4 sets (less than 2 if novice or elderly
Rest
- 1-3 minutes between sets is safe and effective

36
Q

After you have a target intensity range, what do you do?

A

Establish specific weights using 1RMs
- 1 RM is movement/exercise specific (ex. squat, bench press)

37
Q

1- Repetition Max (%1RM)

A

1 RM = Weight lifted/ (%1RM value from table/100)
- look at number of reps

38
Q

Why do we predict 1 - Repetition Max?

A

Measuring directly involves risk of injury

39
Q

Trends of Strength Training

A

As we get closer to 100% intensity (%1RM) from novice to intermediate to advanced:
- number of sets increases
- number of reps decreases
- minutes of rest increase

40
Q

What do we need to consider in making the decision about order of exercises/exercise selection?

A

FIRST: multi-joint, large muscle groups first, most demanding, require power
AFTER: single-joint, small muscle groups, least demanding

41
Q

Progression/Load Increases for Novice Exercisers vs Advanced Exercisers

A

Upper body (assistive/isolation exercises) and lower body (compound exercises)
Novice - less added weight per progression (conservative approach)
Advanced - more added weight per progression

42
Q

How should you time your aerobic training and other components of workout?

A

Depends on your goals
- higher availability of energy at the start
- motivation lacks as you move forward
