8Physical Activity and Your Health Physical activity helps teens’ health in many ways.physical activity Any movement that makes your body use extra energyClimbing stairs, carrying books, and peddling your bike are all movements that add up to lots of physical activity.
9Physical Activity and Your Health Fitness can be achieved through exercise.fitness Being able to handle physical work and play each day without getting overly tiredBeing physically fit is a great strategy for improving and maintaining personal health.

Being physically fit will allow you to handle more activity in your day and not feel tired.exercise Planned physical activity done regularly to build or maintain one’s fitness
10Benefits of Physical Activity Benefits of being physically fit include:Building and maintaining bones and musclesManaging body weightMaintaining a healthy blood pressureMaintaining heart and lung healthReducing stressIncreasing social healthAn active lifestyle:Is good for your brain as well as your bodyIncreases self-confidenceIncreases the likelihood of meeting people
11Your Responsibility to Yourself When you do what is best for your wellness, you are taking responsibility for your personal health behaviors. This shows you are mature. Others will trust you to make the right choices to care for yourself.
12Elements of Physical Fitness Five Elements of Physical FitnessMuscle EnduranceCardiovascular EnduranceStrengthLearning about these elements will help you assess and improve your own fitness levels.FlexibilityBody Composition
13EnduranceBuilding overall endurance and muscle endurance can be achieved by spending more time doing a chosen exercise or physical activity.endurance The ability to perform difficult physical activity without getting overly tiredEndurance is important because it allows you to stay active for a long time.If you can run several miles and your legs don’t feel tired, your legs have muscle endurance.muscle endurance The ability of a muscle to repeatedly use force over a period of time
14EnduranceYou can build cardiovascular endurance by doing aerobic exercises for 30 minutes at least three times a week.If you are breathing so hard during exercise you can’t speak in sentences, your activity is vigorous.If you can carry on a conversation during exercise, you activity is light to moderate.Cardiovascular endurance is also a measure of how quickly your heartbeat and breathing return to normal after you stop exercising.cardiovascular endurance The measure of how well your heart and lungs work during moderate-to- vigorous physical activity or exercise
15StrengthThe amount of work your muscles can do at a given time is a measure of your strength.strength The ability of your muscles to use forceLifting weights is one of many ways to build and maintain muscle strength and increase bone strength.Lifting weights makes your body burn more energy for many hours.By increasing strength, you lessen the chances of getting lower back pain and hurting yourself when lifting things.
16You can increase your flexibility with regular, gentle stretches. flexibility The ability to move joints fully and easily through a full range of motionWhen you are flexible, you feel more comfortable and will be less likely to injure yourself when you exercise or play.
18Types of ExerciseMost physical activities and exercises can be described as aerobic exercise or anaerobic exercise.aerobic exercise Rhythmic, moderate-to-vigorous activity that uses large amounts of oxygen and works the heart and lungsExamples of aerobic exercise include:RunningDancingSwimming lapsBicyclingExamples of anaerobic exercise include:Lifting weightsSprintinganaerobic exercise Intense physical activity that builds muscle but does not use large amounts of oxygen
19Effects of Body Composition on Fitness Physical fitness is tied to body composition.body composition The proportions of fat, bone, muscle, and fluid that make up your body weightGaining muscle and losing fat through regular exercise will help you stay within a healthy weight range and help protect you against diseases like heart disease and cancer.If you exercise regularly, your body can gain muscle and lose fat.
20Measuring Your Fitness Common Fitness TestsBalanceFlexibilityStrengthCardiovascular EnduranceBalance:Stand on one leg for as long as possible. Check your time with a stopwatch.Flexibility:Sit on the floor with your shoes off. Place a ruler between your feet with your heels at the start of the ruler. Keep your knees straight and slowly reach forward with both hands. How far can your reach?Strength:To test abdominal strength:Do stomach crunches for one minute without stopping.To test upper-body strength:Do as many modified push-ups (knees bent) as you can in one minute.Cardiovascular endurance:You will need a 12-inch high block or bench for this test. Before you start, take your pulse for 1 minute to determine your heart rate. Step up to place both feet on the block, then step down. Repeat this stepping motion in a regular rhythm for 3 minutes. Then take your pulse again for 1 minute. The more fit you are, the less your heart rate will increase.
21Lesson 1 ReviewWhat I LearnedRestate Name three ways that physical activity can benefit mental/emotional health.Sample answer: Physical activity can enhance self-confidence, increase mental alertness, and reduce stress.

23What I Learned List What are the three elements of fitness? Lesson 1 ReviewWhat I LearnedList What are the three elements of fitness?endurance, strength, and flexibility
24What I Learned Describe What is body composition? Lesson 1 Review Body composition is the proportions of fat, bone, muscle, and fluid that make up body weight.
25Lesson 1 ReviewThinking CriticallyInfer Why might stretching help a person perform better at a sport?Stretching increases flexibility, which makes you more agile at sports.
26Lesson 1 ReviewThinking CriticallyEvaluate In a brief paragraph, describe your own thoughts and feelings about the benefits of being physically fit.Answers will vary but might include feeling and looking better, being healthier, and having more social opportunities.
