Q

How does PA decrease CVD disease

A

Regular PA participation…

  • Increases hearts “fitness” coronary circulation
  • increases EE
  • decreases inflammatory response in body
  • decreases coagulants in blood
  • decreases insulin resistance

    • 2 min light/moderate intensity activity breaks every 20-30 min.

Q

How does PA reduce cancer?

A
  1. lowers sex hormones
    - Directly: exercise decreases estrogens and androgens because fat tissue produces estrogens
    - Indirectly: less fat tissue
  2. Reduces insulin resistance
    - insulin enhances cell proliferation, immediate and chronic
  3. lowers systemic inflammation
  4. reduced colon transit time

  • genetic influences “hunger” , fullness, exercise enjoyment
71
Q

Probable contribution to body fatness: behavioral

A

Consumption of excess calories, lack of regular PA, no time / motivation / too busy

72
Q

Probable contribution to body fatness: Environmental

A

Macro (community), Micro (home)

  • sedentary (work/leisure)
  • transportation (car)
  • PA removed as requirement for daily life
  • “mindless” eating
73
Q

Obesity risk factors: modifiable and non-modifiable

A

Modifiable:

  • physical inactivity
  • excess calorie intake
  • low socioeconomic status

Non-modifiable:

  • age
  • heredity
  • ethnicity/race
  • metabolism
  • culture
74
Q

Weight loss goal? “Healthy” recommendation

A

Lose 10% of body weight in 6 months

  • for 250 lb person = 25 lb
  • 4 lb / month
75
Q

PA and weight: important to know the difference between…

A
  1. weight stability = < 3% change in weight
  2. weight loss = at least 5% loss of body weight
  3. weight loss maintenance = maintaining within 3-5% of new weight
76
Q

Evidence PA and weight: weight maintenance

A

PA consistently associated with maintenance

  • but with resistance training not as strong
  • 150 min. moderate / 75 min. vigorous or combo
77
Q

Evidence PA and weight: weight loss

A

require big amount of EE

- 60 min. moderate / 20 min. vigorous daily

78
Q

Evidence PA and weight: prevention of weight gain

A

moderate evidence that PA can help sustain weight loss

- 75 moderate / 25 vigorous daily

79
Q

PA and weight

A

Exercise = not cure losing weight, weight loss, maintenance, preventing weight regain or decreasing abdominal fat

Significant increase in EE

  • moderate PA = 4.9%
  • vigorous PA = 11%
80
Q

PA guidelines

A

Overweight/obese people should aim to meet PA guidelines

May not be enough to cause weight loss or maintain weight loss –> aim to achieve 300 min. of moderate PA or 150 min. of vigorous PA plus RT

81
Q

Important considerations: Obesity

A

Not just about PA - overconsumption is a big factor

  • PA alone will not typically result in weight loss
  • Sedentary time is increasing (work/leisure)
  • Substantial benefits from PA/exercise other than just preventing obesity or decreasing weight
82
Q

How do we focus on weight?

A

Easy to measure

  • sense of accomplishment (goals)
  • cultural emphasis
  • when weight decreases PA gets easier
  • many people experience positive physical, social, and psychological outcomes (caused by weight loss?)
    • do any experiences have negative outcomes
83
Q

Paradigm

A

A worldview underlying the theories and methodology of a particular scientific subject

84
Q

Health at every size (HAES)

A

Shift to health promotion vs weight management; weight loss is not the goal

  • encourages body acceptance as opposed to weight loss maintenance
  • supports “intuitive eating”
  • supports active living vs structured exercise
85
Q

Article: Evaluating the Evidence for a paradigm shift

A

This article for HEAS gives evidence as to why this shift should be focus

86
Q

Assumptions - Weight Loss Paradigm

A
  • mortality risk
  • morbidity risk
  • longevity
  • weight loss maintenance
  • weight loss as practical and positive goal
  • improve health through weight loss
  • obesity related costs
87
Q

Assumption: Adiposity increases mortality

A
  1. BMI weakly predicts mortality
    - exceptions at BMI extremes (>40)
  2. NHANES - longevity study
    - greatest longevity in overweight category
  3. When you account for other risk factors (socioeconomic status), association with BMI and mortality much smaller
88
Q

“Obese paradox”

A
  1. Obesity associated with longer survival
    - comparing overweight individuals with thinner people with the same conditions
    - diabetes, hypertension, CV disease, kidney disease
    - obese senior citizens live longer
  2. Life expectancy continue to rise
    - 1970 –> 70.8 years
    - 2005 –> 77.8 years
89
Q

Assumption: Adiposity increases morbidity

A
  1. Obesity is associated with the risk of increased risk for many diseases
    - causation not well established
    - cause –> effect: need metabolic pathway (thinner people have conditions too; one pathway or multiple?)
  2. Weight cycling
    - increased inflammation in tissues
    - increased hypertension, insulin resistance, dyslipidemia
    - increased mortality risk
90
Q

Assumption: Weight loss prolongs life

A
  1. Weight loss increases risk of premature death among obese (even when intentional)
  2. Weight loss improves health markers
    - health behaviors are changing as well
    - not sure as to what extent changes attributes to the weight loss
  3. Liposuction (subcutaneous fat)
    - does not improve BP, lipids or insulin sensitivity
  4. Diabetes - behavior changes
    - glucose control evident within days of making changes
  5. Health benefits - rarely show a does response with weight loss
    - benefits from small changes in weight
    - may not need to achieve “optimal” BMI to improve health
91
Q

Assumption: Anyone who is determined can lose weight and keep it off

A
  1. Majority of people who lose weight gain it all back within 5 years
  2. Most people find it hard to lose weight in the current environmental and societal conditions
  3. Weight control registry - tracks individuals who have sustained weight loss
92
Q

Assumption: Pursuit of weight loss is practical and positive –> dieting

A
  1. Weight cycling is most common result
  2. decrease in bone density
  3. causes psychological stress and increases cortisol
  4. persistent organic pollutants (increases risk for disease - diabetes)
93
Q

Assumption: Pursuit of weight loss is practical and positive –> weight focus

A
  1. Anxiety about weight
  2. body dissatisfaction
  3. weight stigmatization/discrimination
94
Q

Assumption: only way for overweight/obese to improve health is to lose weight

A
  1. untested hypothesis
    - not sure if weight loss will decrease risk to the level as those who were never obese
  2. Healthy behaviors - increase health indicators
    - reduce BP
    - exercise increases insulin sensitivity in lipids even in those who gain body fat
95
Q

Obesity - large economic burden

A

Data often fails to account for…

  • physical inactivity
  • nutrition habits
  • history of weight cycling
  • degree of discrimination
  • access to quality medical care

all of which are associated with body weight and health

Body image - much bigger impact on health than size

  • cost of over treating and obese testing
  • cost of overlooking the normal weight people who need treatment

  • threshold training - train at lactate threshold
102
Q

Relative Exercise Intensity Methods

A
  1. Rating of Perceived Exertion
    - 12-16 (6-20 scale)
  2. Heart Rate
    - HR Max = 57-94%
    - HR Reserve = 40-85%
  3. % VO2 or MET max = 40-85%
103
Q

Heart Rate Methods Using HRmax –> declines with age

A

Determine HRmax

  1. GXT measured
  2. Prediction equations
    - 206.7 - (.67 x age)
    - 220 - age
104
Q

Heart Rate (HR) Max Method: equation

A

EQUATION: exercise HR = HRmax x Intensity

105
Q

Heart Rate (HR) Max Method: 22 year old with goal of exercising at 55 to 90% max

A

1st: Determine max HR
HRmax = 220 - 22 (age) = 198 bpm

2nd: Determine lower exercise HR
exercise HR (55%) = 198 x .55 = 109 bpm
3rd. Determine higher exercise HR
exercise HR (90%) = 198 x .90 = 178 bpm
106
Q

Heart Rate Reserve (HRR) Method: equation

A

Exercise HR = (HRR x intensity) + HRest

107
Q

Heart Rate Reserve (HRR) Method: 22 years, HRest = 68 bpm, exercise at 40-85%max

A

1st: Determine HR max
220 - 22 = 198 bpm

  1. Determine HHR
    198 - 68 bpm = 130 bmp

3rd: Determine lower exercise HR
HR1 = (130 x .40) + 68 = 120 bpm
HR2 = (130 x .85) + 68 = 178 bpm

108
Q

VO2max (METS) –> Training intensity

A

Train at 40-85% VO2max
- equation: training intensity = VO2max x (% effort / 100)

Suppose VO2max = 12 MET

40% intensity = 12(40/100) = 4.8 MET (or just 12x.4)
85% intensity = 12(85/100) = 10.2 MET (or just 12x.85)
