32
Q

What is the FITT Principle?

A
  1. Frequency: frequency of exercise, how often are the exercises performed (3x/day/3x/week)
  2. Intensity: how difficult/challenging are the exercises
    - Sets/reps/resistance
  3. Time: how long are the exercises being performed
    - Endurance – longer
    - Power- shorter
  4. Type: what type of exercises are being performed (strength, endurance, power, flexibility, etc)
33
Q

What is the overload principle?

A
  1. Muscle must be challenged to perform at a level greater than it is accustomed, IT SHOULD BE DIFFICULT.
  2. To ensure overloading progressively increase the intensity, volume, and/or speed
34
Q

What is the SAID principle?

A
  1. Specific Adaptation to Imposed Demands (SAID): Adaptive effects of training are highly specific to training method employed
  2. Clinical reasoning: Exercise selection should be based off creating training effects that best meet specific functional needs and goals of patient
35
Q

What is the reversibility principle?

A

Benefits are transient unless regularly used for functional activities or individual participates in maintenance program

36
Q

How long does detraining take to occur?

A

1-2 weeks after stopping specific exercise

37
Q

Why is it important to think about the reversibility principle when creating HEPs?

A

Clinical reasoning: Why “home exercise programs” should be modified throughout the plan of care, reinforced and program should be sustainable/ reasonable for your client even after discharge

38
Q

Transfer of training/overflow principle -

A
  1. potential carry over of the effects of one exercise into other exercises or activities
  2. in direct contrast to SAID principle
39
Q

T/F Little carry over seen from endurance program to strength.

A

True, Strength programs may have positive effect on endurance

40
Q

How does the size of a muscle affect the tension produced?

A

Larger the muscle diameter generally the > tension production

41
Q

Short fibers with pinnate and multipinnate (>/=/

A
  1. Short fibers with pinnate and multipinnate design lead to > force production
  2. Long parallel fibers in muscles with high rate of shortening lead to < force production (sartorius)
42
Q

Describe high % of type 1 muscle fibers:

A

low force production, slow rate of maximum force production, resistant to fatigue (marathon runners)

43
Q

Describe high % of type 2a and 2b muscle fubersd:

A

rapid high force production, rapid fatigue (body builders)

44
Q

At what range of contraction will muscles produce the greatest tension?

A

mid range of contraction - cross linkage optimal = optimal force production

45
Q

If you have a greater # and synchronization of motor unit firing, what type of force production?

A

greater force production

46
Q

Isometric, concentric, eccentric

List in order from greatest to least force production

A
  1. Eccentric
  2. Isometric
  3. Concentric
47
Q

What is a gradual decrease in force-producing capacity of the neuromuscular system?

A

Muscle fatigue

48
Q

What are signs of fatigue?

A
  1. Pain or cramping of the muscle
  2. Tremors of the contracting muscle
  3. Unintentional slowing of performing repetitions
  4. Active movements become jerky
  5. Unable to complete appropriate movement pattern through full ROM against same level of resistance
  6. Use of substitutions strategies (quality not quantity) - May lead to injury!
49

5%

54
Q

Improved strength in older adults is associated with what?

A

improved health, quality of life, functional capacity, and reduced risk of falls

55
Q

Why should valsalva maneuver be avoided with older patients?

A

Leads to an increase in intra- abdominal and intra thoracic pressure which can lead to an overall abrupt increase in BP (stroke, hx cardiac illness, eye/cranial surgery, IV disc path)

56
Q

If patient has CV pathology or HTN, can patient perform resistance exercise?

A

can perform resistance exercise, however, need to be monitored closely (can get them to count out loud to prevent holding breath)

(Inhalation/exhalation)

encourage _______ when lifting and _______when lowering

A

encourage exhalation when lifting and inhalations when lowering

58
Q

How can you avoid potentially harmful substitutions of body?

A
  1. inadequate rest periods
  2. dehydration

60
Q

Describe the time period of delayed onset muscle soreness (DOMS):

Peaks =
Subsides =

A

A

maybe don’t move forward, do change treatment

A

True

67

For patient with osteoporosis, how would you initially assign a workout program to them?

A
  1. 1 set of higher repetitions (muscular endurance training)

A

lunges, step ups/downs

A

avoid weighted torsional type movements around the hip

71
