Physical activity improves reaction time by helping you respond more quickly to stimuli.

Approaches to Everyday Activities
Fitting Physical Activity into Your Life
Health professionals recommend teens incorporate 60 minutes of moderate physical activity into their daily lives.
Think about how much time you sit in front of the TV, yet you complain about not having energy.
We all have goals, whether it is to lose fat, gain muscle, or just feel better.
Do your daily activities move you toward your goals, or away from your goals?
Squat 'Til You Puke
Physical Activity: any form of movement that causes your body to use energy
Physical Fitness: the ability to carry out daily tasks easily and have enough reserve energy to respond to unexpected demands
Sedentary Lifestyle: way of life that involves little physical activity
Osteoporosis: condition characterized by a decrease in bone density, producing porous and fragile bones
Metabolism: process by which your body gets energy from food
Risks of Physical Inactivity
More than one in three teens do not participate regularly in vigorous activity (20 minutes three times a week).
Regular participation in vigorous physical activity declines significantly during the teen years, from 73% of ninth graders to 61% of twelfth graders
Only 29% of teens attend a daily physical education class
CDC Troubling Facts
Unhealthful weight gain, which can lead to:
Type 2 Diabetes
Increased risk of osteoporosis
Reduced ability to manage stress
Decreased opportunities to meet and form friendships with active people who value and live a healthy lifestyle.
Results of a Sedentary Lifestyle
Other Obvious Reasons
Eat Delicious or...
Instant gratification from eating something that tastes good
Feeling of satiety
Look Delicious. You Decide.
Feeling of accomplishment
Better body image
Sense of control
Lesson 2: p. 80 - 86
Fitness and You
Ability of the heart, lungs and blood vessels to utilize and send fuel and oxygen to the body's tissues during long periods of moderate to vigorous activity.
Test: step test
Can you think of examples?
Why would this be so important?
Amount of force a muscle can exert.
Test: curl-ups & arm hang
Which athletes are known for muscular strength?
Who do you know that is particularly strong?
Ability of the muscles to perform physical tasks over a period of time without becoming fatigued.
What types of athletes are known for muscular endurance?
Which sports would this be most important?
Ways of testing (p. 82)
Ability to move a body part through a full range of motion.
Test: sit and reach
Why is flexibility important? (p. 82)
Ratio of body fat to lean body tissue, including muscle, bone, water, and connective tissue such as ligaments, cartilage, and tendons.
Could body composition limit the other elements of fitness?
Various ways to measure
Elements of Fitness
Improving Your Fitness
Aerobic vs. Anaerobic
Activity that uses large muscle groups, is rhythmic in nature, and can be maintained continuously for at least 10 minutes three times a day or for 20 to 30 minutes at one time.
Intense short bursts of activity in which the muscles work so hard that they produce energy without using oxygen.
Survey: Preview text. List any observations you make (pictures, headings, graphs, etc.).
Question: List 3 questions you think you will find answers to.
Predict: State 3 things you think you will learn.
Read: Read text.
Respond: Try to answer your questions from above. Respond to the predictions you made. Did you learn the things you predicted or not? Modify, drop, add.
Summarize: Write a 5-6 sentence summary of the section.
Write examples on board
Measuring Physical Fitness
Create your own tests to evaluate the following elements of fitness. Use the examples on pages 81-83 to guide the design of your own test.
Muscular Strength & Endurance (2 different muscle groups)
Make sure to include
Specific directions for the test, walking participants through the process
Details, details, details! Work on your descriptive writing.
How will a participant know how well they did?
Suggestions toward improving performance
How could someone train to improve his/her score?
