2. Warm-Up Answer the following questions in response to the statistics about obesity 1. What do you find surprising? 2. What do you think is the biggest contributor to childhood obesity? 3. What can we do to prevent childhood obesity? Childhood obesity has more than doubled in children and quadrupled in adolescents in the past 30 years – Ages 6-11: 7% in 1980 to 18% in 2012 and Ages 12- 19: 5% in 1980 to 21% in 2012. More than one or two hours of screen time (TV, computers, video games) each day is a risk factor for childhood obesity Overweight teenagers have a 70% chance of becoming overweight adults Less than one-third of adults are at a healthy weight Two-thirds of adults are now overweight, with a BMI at or above 25. One-third of adults have a BMI at or above 30 and are considered to be obese. Obese youth are more likely to have risk factors for cardiovascular disease, such as high cholesterol or high blood pressure.

3. Basal Metabolism Energy & Calories Food – provide body with energy Calories – primary way to measure energy requirements, actually called kilocalories Kilocalorie = The amount of heat required to raise one kilogram of water 1 degree Celsius.

4. Basal Metabolic & Activity Energy The amount of energy the body needs is divided into 2 categories: Basal Metabolic – BMR is the amount of energy required to maintain body functions while the body is at rest. Activity Energy – Depends on how active you are, the more active the more calories required.

5. Calories Weight Gain Calories In = Energy In Excess Calories Stored as Fat Weight Gain More Active = More Calories Burned Burn more calories than take in Calorie Deficit 1 pound fat = 3500 calories

6. Anabolism & Catabolism Metabolism composed of 2 parts: Anabolism – the energy requiring process that joins smaller molecules together to form larger molecules. Catabolism – the energy releasing process which breaks large molecules down into smaller molecules.

7. BMR Basal Metabolic Rate (BMR) – the amount of energy required to maintain the body when in a resting state – the amount of calories you burn when resting. Basal Metabolism aides in: muscle tone, body temp maintenance, heartbeat, and many other functions

9. Factors that Affect BMR Age Gender Height Growth/Pregnancy Body Composition Fever Thyroxine Epinephrine (adrenaline) Fasting/Starvation Malnutrition Environmental Temperature Stress

10. BMR X 20% BMR X 30% BMR X 40% BMR X 50% BMR X 60% BMR + Activity Factor = Calories to maintain current weight

12. Physical Fitness

13. Percentage of High School Students Participating in Physical Activity and Physical Education in 2013 Type of ActivityFemalesMales Physically active at least 60 minutes/day 17.7%36.6% Attended physical education classes daily 24.0%34.9% Source: CDC. Youth Risk Behavior Surveillance—United States, 2013 Participation in physical activity declines as young people age.

14. Physical Activity Guidelines for ages 6-17 years Children and adolescents should have 60 minutes (1 hour) or more of physical activity daily. Aerobic: Most of the 60 or more minutes a day should be either moderate- or vigorous-intensity aerobic physical activity at least 3 days a week. Muscle-strengthening: at least 3 days of the week. Bone-strengthening: at least 3 days of the week.

15. Benefits of Regular Physical Activity Helps build and maintain healthy bones and muscles. Helps reduce the risk of developing obesity and chronic diseases, such as diabetes, cardiovascular disease, and colon cancer. Reduces feelings of depression and anxiety and promotes psychological well-being. May help improve students’ academic performance, including Academic achievement and grades Academic behavior, such as time on task Factors that influence academic achievement, such as concentration and attentiveness in the classroom.

16. Long-Term Consequences of Physical Inactivity Overweight and obesity, which are influenced by physical inactivity and poor diet, can increase one’s risk for diabetes, high blood pressure, high cholesterol, asthma, arthritis, and poor health status.obesity Physical inactivity increases one’s risk for dying prematurely, dying of heart disease, and developing diabetes, colon cancer, and high blood pressure.

17. 10 Exercise Tips Here are 10 simple ways to make an exercise lifestyle change: 1. Go outside for a walk. 2. Take the stairs instead of the elevator. 3. Instead of driving, walk or bike to places like school or a friend's house. 4. If you have to drive, park farther away than you need to and walk the extra distance, if it's safe to do so. 5. Vacuum your room, wash the car, or mow the lawn. It's not a chore — it's an exercise opportunity!

18. 10 Exercise Tips Here are 10 simple ways to make an exercise lifestyle change: 6. Limit your time watching TV, using the computer, or playing video games — Try to keep screen time to no more than 2 hours a day, not including time spent doing homework. 7. Dance. It could help you burn more than 300 calories an hour! 8. Figure out what type of exercise interests you, then give it a try! Find an exercise buddy to join you. It's usually easier to stay motivated about exercise if you do something you're interested in. 9. If you get bored or lose interest easily, alternate the kinds of activities you do so they always feel fresh. 10. Be sure to include some activity that gets your heart beating faster, quickens your breathing, and makes you sweat.
