Q

What is VO2 max?

A

The maximal volume of oxygen consumed per ml/kg/min
Resting rate: ~3.5ml/kg/min
Typical measure for a man ~30: 40-47ml/kg/min
Reflection of how much oxygen-rich blood you can deliver to working muscle

39
Q

What is Vo2peak?

A

Highest attainable Vo2 value for the given exercise. Used when the levelling off (plateau) of Vo2 does not occur. Individual still reaches the end of the test

40
Q

What is the relative vs absolute measure for VO2 max?

A

relative measure: ml/kg/min
absolute measure: L/min

41
Q

What is the gold standard way of measuring VO2 max/peak testing? Explain

A

open circuit spirometry (indirect calorimetry)
- measured directly in the lab using a valve to measure oxygen and carbon dioxide. The mode selected can impact the results (treadmill vs cycle ergometer)

42
Q

What is the general procedure of conducting a submax CRF test

A
  1. Obtain resting HR and BP prior to exercise in the exercise posture
  2. Familiarize the individual with the treadmill or ergometer
  3. Begin with a 2-3 min warm up to acquaint the individual with the treadmill/ergometer
  4. Specific protocol should be done in 2-3 min stages and the appropriate increments in work rate
  5. HR should be monitored at least two times near the end of the second and third min of each stage
  6. BP should be monitored in the last min of each stage and repeated if hypotensive or hypertensive
  7. RPE and other scales should be monitored near the end of each stage
  8. individual’s symptoms and appearance should be monitored and recorded regularly
  9. Test ends when an individual reaches 70% of HRR, fails to adhere to test protocol, shows adverse signs and symptoms, and requests. to stop or has a medical emergency
  10. Need to have a cool-down period
  11. Physiologic observations should continue 5 min after the test unless abnormal responses occur
43
Q

What are three modes of CRF testing and examples of each?

A
  1. Treadmill tests (i.e modified bruce)
  2. Cycle ergometer (e.g., Astrand, YMCA)
  3. Field tests (e.g., cooper 12 min test, Rockport one-mile fitness test, walking test, 6 min walk test)
44
Q

What is the Cooper 12-minute test?

A

A CRF field test requires the individual to cover the greatest distance in the allotted time period. Vo2 max can be estimated using the equation : (distance in meters - 504.9)/44.73

45
Q

What is the Rockport one-mile fitness test?

A

A CRF test requires the individual to walk 1 mile as fast as they can. HR is obtained in the final minute.

46
Q

What is the 6 min walk test?

A

A CRF field test is used for individuals with a predicted low CRF. Aim to walk over 300m in 6 min. A sub max test but since given to older individuals/those w chronic disease they may come close to reaching their max

47
Q

What is a good Vo2 max number?

A

Treadmill-based values*** Cycle ergometer will be 5-10%.

Men in 20s = in the 50sml/kg/min

Women in 20s = ~40sml/kg/min

48
Q

What is an excellent VO2max/peak for men and women in their 50s? Treadmill vs Cycle Ergometer

A

Treadmill:
- Men; 43.2mls/kg/min
- Women; 30.2mls/kg/min

Cycle Ergometer:
- Men: 32.1mls/kg/min
-Women: 21.5mls/kg/min

49
Q

What is overload?

A

A training regime of greater intensity than the individual is accustomed to

Most of the time trying to get patients to lift one weight or two, rather than 100lbs or 200lbs

50
Q

Explain the Law of Overload

A

1.Start with a stimulus = workout
- Stimulus needs to be above a certain threshold (different thresholds based off aerobic fitness)
- generally, 40-80% of HRR (deconditioned people may need 30%)
2.Fatigue occurs soon after the stimulus
3.Compensate: the body takes time (1-3 days) to respond and rebuild
4. Overcompensate: body and systems come back stronger - a result of compenstion

51
Q

What are some Adaptations from overload?

A

Capillarization
Increases In aVo2 diff
Improved endothelial functions
Oxidize fatty acids
Increase mitochondria size
Increase muscle size + ability to recruit muscle size

52
Q

Explain progression

A

If you do not progress in training you will plateau
Progressing too quickly is dangerous***
10% rule:
- ACSM says to increase any of the FITT-VP parameters by 5-19% every two weeks
-Avoid progressing more than one parameter at once

53
Q

How do you progress training

A

10% rule - one parameter at a time
Increase intensity (e.g. weight, speed)
More repetitions, sets, time
Less rest, the recovery period in HITT aerobic program, in resistance training sets
Increase # of sessions in a week
New harder multi-joint exercises
Ex: plank
Two elbows on the floor, then lift elbow or leg, go onto side etc

54
Q

What does Specificity mean when creating a fitness program?

A

We specify exercises to elicit specific adaptations to create particular training effects

to optimize performance and maximize the translation of training, you want to mimic movements as closely as possible

55
Q

What are the types of specificity?

A

Movement specificity: try to mimic the pattern of movements (or angle of joints)

Metabolic specificity:
Strength training yields specific strength adaptations
Ex: muscle fibre size

Temporal specificity:
Performance optimized at the same time you train
Ex: if games @ 8 pm you should train at 8 pm

Mode specificity:
Aerobic training benefits usually stick with the mode of training you are doing

56
Q

Explain the concept of Individuality

A

Adaptations to training are unique to individuals and vary with:
One’s baseline fitness
Individual “responsiveness”

57
Q

Explain the findings from the twin research in individuality

A

Twin A (x- axis) vs twin B (y axis)
College rec athletes introduced to aerobic training program
Important: strong correlation between improvement in twin sets
Ex: If twin a improve vo2 max 40%, twin B improved 30%
Illustrates impact that genetic makeup can have on individuality responsiveness on training program

58
Q

What is periodization

A
  • The organization of an individual’s training into cycles to promote peak condition

Team sports:
high volume, lower intensity further from the competitive season
- focuses on improving aerobic capacity and muscle strength

closer to the season: low volume, higher intensity, maximizes benefits, speed, power and agility

59
Q

Explain the importance of rest in making a fitness program

A

exercises using multiple joints may require more rest

Aerobic training should be 5x a week, 6 and 7th days should be rest

Without adequate rest you are overtraining and will result in no overcompensation

60
Q

Explain reversibility

A

The loss of physiological and performance training adaptations

Can occur quickly

College athletes asked to detrain

VoO2 max drops @ day 12 ~6-7% (two weeks of de-training)stroke volume and cardiac output also decrease

aVo2 diff maintains then drops at 56 days
HR max increases (could be a result of lower SV and CO)

Best way to mitigate or reduce reversibility: maintain a FITT-VP principle
INTENSITY = best

Even if you drop frequency or volume you can still be fit (maintain VO2 and other physiological variables)

61
Q

What makes up a comprehensive exercise program?

A

Aerobic, resistance, sedentary behaviour (tackle as a separate movements behaviour) flexibility, neuromuscular/balance

An exercise program including all of the above is essential in maintaining physical fitness and health

Pick 1-2 exercises for the program, choosing all four makes it difficult to keep routine

62
Q

What are the Canadian 24-hr Movement Guidelines for Adults

A

7-9 hours of good quality sleep have a consistent bedtime and wake-up time

Walk or stand after 45 min of sedentary behaviour (at least 2 min)

MVPA no longer needs to be in bouts at least 10 min long, just needs to meet 150min

limit sedentary behaviour to 8 hours or less

no more than 3 hours of recreational screen time

Constant movement
- Several hours of light physical activities, including standing
Progressing towards any of these targets will result in some health benefits
Important to have people try to reach the guidelines since some movement is better than none

63
Q

What are the ACSM’s guidelines for Aerobic exercise (FITT-VP)

A

Frequency: 3-5 days/week
Intensity: 40-89% HRR
Time: 20-60 minutes
Type: large, rhythmic eg, swimming
Volume: mins of MVPA/week
Progress: 10% rule
Pattern: MICE, interme, HITT

64
Q

Why is it important to exercise 3-5 days a week?

A

In general, cannot reasonably accept improvements in less than 3 days a week

Why not more than 5 days a week = can cause MSI, no time for recovery, benefits, / fitness can plateau, and increase cardiovascular events

If the athlete and already fit - can go up to 6-7 days but can if cross training (running some days and yoga others)
Do not do MVPA 7 days a week

65
Q

What are the three ways to prescribe exercise intensity?

A
  1. Borg RPE scale
  2. The talk test
  3. %HRR
66
Q

What are the three ways to prescribe exercise intensity?

A
  1. Borg RPE scale
  2. The talk test
  3. %HRR
67
Q

What is the talk test?

A

A way to prescribe exercise intensity

Ask individuals to participate in exercise task

If they are gasping for air - the vigorous zone Over 9 METS)

If they can get 3-5 words without gasping = moderate (3-6 METs)

Conversation = light (1.5-3 METs)

68
Q

What are the components of an aerobic exercise training session?

A

Start: 5-10 mins light to moderate intensity activity
Cardiovascular Drift: heart rate climbs over course of the workout
This is why intensity is in a range (fluctuates)
5-10 minutes of cool down
Light to moderate activity
Warm-up: injury prevention
Cool down: gradual recovery - heart rate back to baseline
- Clear metabolites
- Venous cooling

69
Q

Warm-up, How? and Why?

A

How: Light to moderate intensity exercise activities to target specific muscle groups that will be used during exercise

Why: Dynamic stretches, never static stretches

70
Q

Cool-down, How? and Why?

A

How? : Low-moderate intensity flexibility exercises or static stretching
Why?: Return to near resting levels, oxygen level, heart rate, etc after exercising

71
Q

Stretch: flexibility training (How?, Why?)

A

How?: hold the static stretch untill before discomfort 30/90s for every major muscle group

Why? Maximizes performance

72
Q

Cross-train, How? Why?

A

How? Using different training modes (running, swimming, walking)

Why? Prevents injury, promotes rest, targets different muscle groups, is motivated longer, a better position to do more vigorous exercise since not tired in legs, etc

73
Q

Rest, How? Why?

A

How? Having breaks in between exercises, and sleeping

Why? Reduce chances of overcompensation without rest, adequate sleep, rest days week days of rest between vigorous bouts of exercise/modes of each exercise

74
Q

Gradual Progression of volume/intensity, How? Why?

A

How? Start low and go slow
Why? Prevent injury, keep motivation

75
Q

How can you progress with Aerobic exercise

A

Use the triangle method:

  1. Establish a routine (base of the triangle)
    On a regular basis, etc once a week, before increasing the volume
    Focus on a routine early on
  2. Increase the volume
    Ideally, guideline levels
    Once they have a regular routine and reached guidelines for a week, then we can start to increase the volume
    Must increase so that it increases vo2 - since cardiac fitness is the most important
  3. Optimize intensity
76
Q

What weer the outcomes of the Study: Developing the P (for progression) in a FITT-VP Exercise Prescription

A

Generally want to progress as slowly as possible to not increase risk of injury
Ex: how to progress someone in a walk-jog program
Beginners will increase mins/week and intensity from light level to moderate
At 10 min to weekly total each week until reaching 100 min
Then increase intently from light to moderate level
Once comfortable, continue to add 10-15 min/week until reaching 150 min
Intermediate level - progress two variables at a time rather than on (pace and time)

77
Q

Why and how do you prescribe a HITT program?

A

Not just for the super fit
A most common pattern in exercise prescription
80% more HRR
Program sample
3-minute warm-up and 2.5 min cooldown
30-second sprints, 90-second active recovery intervals
How to incorporate
Use an app
Can attach intervals of high training to a certain part of a song
Ex; go faster at the chorus
Study results: HITT has greater benefits than MICE training
Better VO2 improvements

78
Q

What is muscular fitness?

A

A term that encompassed:

muscular strength (muscle’s ability to exert maximal force on occasion),

muscular endurance (muscle’s ability to continue to perform successively exerts or repetitions against a submaximal load)

and muscular power (muscles’ ability to exert force per unit of time)

79
Q

What are the ACSM FITTVPP guidelines for resistance training exercise prescription

A

F: 2-3d (per muscles group)
I: 60-80%, 1RM
% varies depending on goal: hypertrophy, strength, power, endurance
Deconditioned adults: get them to do 5-10 times and then you can predict 1RM
60-80% helps achieve 8-12 reps in a set, you will max hypertrophy and strength gains this way, most important for health benefits

T: 8-12 reps, 2-4 sets, 2 min rest

T: 10 major muscle group, multijoint (usually preferred) vs single joint, core exercises (abdominal, hip and lower back)

V: sets/week

P: increase load or volume or reduce rest or increase complexity (front plank on knees, to
toes, to side plank) - fiddle with the platform

P: full body (all 10 muscle groups), split (half muscle group) , circuit (exercises in sequence)

80
Q

What are the major muscle groups?

A

Chest, biceps, triceps, quads, glutes, hamstrings, calf, back, abs, shoulders,

81
Q

What are the five benefits of increasing muscle mass

A

Increases resting metabolic rate
Decreases risk of injury (by increasing integrity of bone/muscle/tendon capsule
Bone strength
Functional independence
Better glycemic control (more muscle = more glucose muscles can take up to use for energy)

82
Q

What are the two ways to prescribe exercise intensity in resistance training

A

RPE and %1-RM

83
Q

How do you practically progress resistance training?

A

Increasing load by 5%, adding more repetitions, increasing the number of sets/week

84
Q

What are 3 patterns of resistance training programming

A

Full body (all 10 muscle groups), split (half muscle groups), circuit (exercises in sequence)

85
Q

What are 3 patterns of resistance training programming

A

Full body (all 10 muscle groups), split (half muscle groups), circuit (exercises in sequence)

86
Q

What’s a compound exercise?

A

Exercises that work multiple muscle groups at the same time

87
Q

What is progressive overload and why is it important

A

A gradual increase in stress is placed on the body.

Important because it subjects the muscles to greater stimuli for continues increase in muscular fitness
