What have studies shown in terms of lean individuals and those who sit?

Individuals sit 2 hours more than lean individuals

If they adopted neat at level of lean individuals, they could burn and additional 350kcals/days
Suggested that 280-350 kcal per day through NEAT may be required for weight loss (a little more calories for Wt loss)

How do we determine what is moderate or vigorous?

Study These Flashcards

% (220-age=max HR)
HR
Conversation Speaking during activity
Sweat rate

What is moderate physical activity?

Study These Flashcards

○ Any activity that causes you to sweat a little and to breath harder
○ RPE: 5-6 (rating of perceived exertion, how hard you think you are working)

%VO2 max: 50-70%

What is vigorous physical activity?

○ Any activity that causes you to swat a lot and be out of breath ○ RPE 7-8 %VO2max:>70%

What is a VO2 test?

Good test increases and then it plateaus, the max amount that your body is able to do VO2 peak when there is an amazing test

Why do we exercise?

``` Release endorphins Sports Enjoyment COmpetitive Physical result Being fit ```

How do you know when you are fit?

Looks, VO2max, Increase in performance, Doing the things you like to do on a daily basis

The ability to carry out daily tasks with vigor and alertness without undue fatigue and with ample energy to enjoy leisure-time pursuits and to meet unforeseen emergencies

What is health as a part of physical fitness?

Balance, Agility coordination, Speed,

What are the 2 sub components of physical fitness?

In children and youth how much time is spent in sedentary pursuits?

62% | -this tends to increase with age

What are the guidelines used for children and youth?

60 min of MVPA at least 6 days/wk VPA at least 3 days/wk

What % of children 6-19 are meeting the VPA of 5 mins/day/week

Only 11% of children are meeting the vigorous gidelines/week 5 mins is good and they go down with increasing minutes

What % of children and youth are meeting 60mins at least 6days/wk?

On average 7% of Canadian children accumulate the 6 days/wk

Based on the 24hr movement guidelines how are children and youth doing?

Average mins of physical activity ○ Boys mostly meeting the average but do more sedentary behaviours and more time in front of screens ○ Girls could be doing better Boys and girls getting more sedentary time, more than the guidelines Sleep for both is okay

Are children and youth meeting all 3 guidelines together?

15% of adults are doing it

How is the world doing on getting enough physical activity?

1/4th population (1.4 billion) don’t get enough PA, | -women get less than men

Higher income countries have higher rates of low physical activity

Which countries have the highest rates of physical inactivity?

Kuwait Saudi Arabia Iraq -highest rates

Which countries have the lowest rates of physical inactivity?

Mozambique and Uganda | -lowest rates of physical inactivity

What are the daily patterns of physical activity in 6-10, 11-14 and 20-79?

``` Children 6-10 • Peak PA is at lunchtime Youth 11-14 and adolescents • Peak PA afterschool • Youth are also quite active during lunch Adults 20-79 • PA is accumulated throughout the day • Weekday=weekend ```

Why should we know patterns of physical activity?

Good to know so to capitalize on these times

What are the results of physical fitness in children and youth them compared to 1980's?

• We have gotten worse with flexibility, muscle strength, waist, BMI -Strength and flexibility decreased and all levels of fitness and body composition is down • 28% of boys 8-10 and 23% girls could not complete a curl up

What are the results of physical fitness in adults compared to 1980's?

Same trends in adults as seen in children and youth Only thing going up os body weight Majority of people over 40 could not complete at least 1 curlup

What factors contribute to the increase in body from the 1980s?

•Technology: groceries, shopping, time efficiency • Larger portion sizes and accessibility of food (feast and famin, and surplus) • Work culture ○ Work place environment • Lifestyle • Mentally tired • Transportation methods instead of walking •City planning

How do we change the trend we are on now?

* Employers have a responsibility to make a more conducive environment for activeness * Teaching more about fitness, how to stay fit for life * Aim for kids because if you build the habits at a younger age they are more likely to value this in the future
