  • Globally 1 in 4 adults do not meet the global recommendations of PA
  • Up to 5 million deaths/year could be adverted if the global population was more active
  • Inactive people have 20-30% increased risk of death compared to people who are sufficiently active

  • tobacco smoking
  • alcohol consumption
  • physical inactivity
  • unhealthy eating
  • sedentary behaviour (new)

ON has high tobacco smoking and alcohol

28
Q

Risk conditions

A

Obesity, hypertension

29
Q

Are Canadians Healthy?

A

Yes, on average Canadians are healthy

30
Q

BMI

A

Ratio of body weight to height squared
18.5-24.9 is normal weight
>30 is obese

31
Q

Global Obesity (risk condition)

A
  • 26% of Canadian adults are obese
  • in Canada and U.S obesity rates are equal between women and men
  • 1/3 of Canadian kids are overweight
32
Q

Hypertension (risk condition)

A
  • Chronic high blood pressure, very common
33
Q

Subjective ways to Measure PA + study results

A

Things like questionnaires and surveys that people don’t necessarily tell the whole truth on

  • Insufficient PA is a leading risk factor for non-communicable diseases and has a negative effect on mental health and quality of life
  • Levels of insufficient PA across countries and estimate global and regional trends
34
Q

Objective Measurements: Accelerometer

A
  • Measures heart rate
  • PA is associated with reduced risk of cardiovascular disease, some types of cancer, osteoporosis, diabetes, obesity, etc.
  • Higher levels of physical activity are clearly associated with health benefits
35
Q

Objective Measurements: Wearables + research

A
  • Canadians walk an average of 5000 steps a day (recommenced is 10)
  • Activity inequality predicts obesity rates better than activity levels
    Activity Inequality: when you’re only moving doing deliberate exercise
36
Q

Physical Activity Guidlines

A
  • According to statistics Canada, only 16% of Canadian adults are getting the recommended amount of physical activity
  • 150 minutes of moderate to vigourous physical activity per week
37
Q

Pedometer vs Accelerometer

A
  • Pedometer only tracks number of steps
  • Accelerometer tracks speed and other stats
38
Q

Blue Zones

A
  • Looks at longevity hot spots around the world
  • Places where people move naturally, have a healthy culture, right outlook on life, eating wisely
  • These behaviours positively affect people’s lives and ultimatley extend their life expectancy
  • Italy and Greece follow this lifestyle
39
Q

Dose Repsonse to PA

A

Dose response describes the body’s reaction to a certain amount of a substance or activity

The more physically active you are in minutes per day, the lower your al cause mortality

40
Q

Step Count and Mortality

A
  • The lower amount of steps a demographic takes a day their higher mortality rate
  • 2000 steps a day has the highest mortality rate
  • Any amount over 10000 is a lower mortality rate
  • Taking very few steps impacts men’s’ mortality more than women’s’
41
Q

Stages of Changing Habits

A
  • Precontemplation:
    Description of the sitting recommendation doesnt match
    my current behaviour and I don’t intend to change
  • Contemplation:
    Description of the sustained sitting recommendation
    doesn’t match my current behaviour but I do intend to
    change in the next 6 months
  • Preparation:
    Description of the sustained sitting recommendation
    doesn’t match my current behaviour but I’m motivated
    and confident that I’ll change in the next month
  • Action
    I follow the description of sustained sitting patterns but
    it’s been less than 6 months
  • Maintenance:
    I’ve followed the description of sustained sitting patterns
    for more than 6 months
42
Q

London England Bus Study

A

The Study examined the risk of coronary heart disease between the drivers and the conductors

  • Drivers are inactive, conductors are active
  • The drivers had a significantly higher risk of coronary heart disease than the conductors
  • Basically if you’re active during the day you have less risk of getting chronic diseases
43
Q

23.5 hours

A

Exercise is medicine

best thing you can do for your health is exercise 30 min/day

More activity is better, but the rate of return decreases after about 30 min per day

44
Q

Standing to avoid sedentary behavior

A
  • Burns slightly more calories per hour
  • Can result in bad circulation
  • good to switch between standing and sitting
45
Q

Light Activities to break up sedentary behavior

A
  • Breaking up periods of sitting reduces glucose and insulin spikes in response to eating
  • breaking up sitting every 60 min positively effects our happiness
46
Q

Factors Affecting our Activity Levels

A
  • Natural enviroment - weather, topography, etc
  • Built enviroment - city, land use patters, gree space
  • Social enviroment - culture, friends, income
  • Individual determinants - gender, age, skills, comfort, etc
47
Q

How to get workers to be me more active

A

Direct physical activity promoting workplace facilities
i.e. group stretching, or ping pong table

Indirect physical activity - promoting workplace facilities
i.e. onsite workout facilities

if the workplace has showers people are way more likely to engage in physical activity

48
Q

Contributors to overall health status

A

Genetics
Enviroment (socioeconomic status, accesible facilities)
Access to medical care
Health behavious

49
Q

Exercise is Medicine

A

A movement around the world, and in Canada that encourages a healthy lifestyle among Canadians

50
Q

Secondary Prevention

A

Exercising to reduce the onset of health issues

Outcomes: Delayed death, lower disease recurrence, lower disease severity, fewer hospitalizations, fewer procedures, fewer medications/lower doses, improved bio-markers/clinical risk factors, faster return to work/life, system cost-savings

51
Q

Exercise and Immunity

A

Exercise instantaneously mobilizes immune cells
Meaning exercise actually increases your immune defense to fight the common cold and flu

If your body isn’t used to exercise and you exercise really vigorously it can harm your immune system

52
Q

Drug Efficacy vs Exercise

A
  • Exercise and drug interventions did NOT differ in terms of mortality benefits or in:
    ○ secondary prevention of coronary heart disease,
    ○ rehabilitation after stroke
    ○ treatment of heart failure, and prevention of
    diabetes

exercise is equally as effective as drugs
exercise is more effective than drugs for stroke prevention

53
Q

PA and Depression

A

People with MDD (major depressive disorders) saw the greatest reduction in symptoms if they included exercise in their treatment

It is recognized that exercise should be the only treatment of mild-moderate depression

may take 4-6 weeks to notice benefits

54
Q

PA and Diabetes

A
  • Type 2 diabetes you still have the use and can produce insulin but your body can’t regulate it in your body
  • This is generally due to lifestyle and eating choices

if a patient does both aerobic and strength exercise it will reduce their A1c by 1%

55
Q

Ischemia:

A

a suppression/reduction of blood flow due to something blocking/compressing the blood vessel

results from bad diet and fat build up

if you exercise 45-60min per day it’ll reduce your symptoms

56
Q

Peripheral benefits of exercise on Ischemia

A
  • Happen faster than central benefits (2-3 weeks)
  • Improves upon your bodies ability to take the oxygen out of the blood and using it
    Circulation to feet and hands improves
57
Q

Central benefits of exercise on Ischemia

A
  • Take longer than peripheral (6 months)
  • More efficient heart contraction in terms of how much blood the heart can move per beat
    Makes exercising easier
58
Q

Exercise effect on plaque development for Ischemia

A
  • with 45+ min of exercise per day you can stop plaque from developing
  • If you exercise 30min/ day it will slow plaque development
  • If you exercise 90min/day 5 days a week you can actually shrink plaque
59
Q

Diabetes Symptoms

A

peeing a lot, slow healing wounds, genital itching, blurred vision, exhaustion, rapid weight loss

60
Q

Musculoskeletal changes during pregnancy

A

Increase force on joints due to increased body mass

ligament laxity due to relaxin hormone release

lumbar lordosis - compression of the spine
