The Importance of Exercise for Teens

Introduction

Cross training - step aerobics - interval training - weight training - yoga - low-impact - high-impact…we live in an exercise-crazed world. We hear these and other fitness terms all the time, but what is really the best fitness plan for teens? What kinds of benefits does exercise provide? Do you need to have a specific plan or is regular, moderate physical activity of any kind beneficial to your health? In this WebQuest, you will discover the answers to these and other questions through researching the benefits of exercise and learning ways to motivate yourself to be physically active.

Your job in this WebQuest is to learn about exercise and the critical importance of physical activity in your daily life. You will explore the many different health benefits of exercise and physical activity, such as strengthening the heart muscle and building muscle strength. You also will investigate many health benefits that you may not have considered before, such as the effect of physical activity on the risk of cancer. After doing your Internet research, you will answer a set of questions. Then, you will make a physical activity plan for yourself. For a period of 3 weeks, you need to set a goal of at least 60 minutes of physical activity per day, which is the recommendation of The President's Council on Physical Fitness and Sports for children and teens ages 6-17. You will record your activities for the day in the chart provided for this WebQuest, and write one journal entry for each week discussing your plan and the results of your physical activities.

Before beginning your Internet research, read the following questions. As you visit the resource Web sites, look for information that will help you answer the questions.

1. List three reasons it is important for teens to get regular physical exercise.
2. Why is it better for a person to start exercising when he or she is young instead of waiting until he or she is an adult?
3. Name three health benefits of physical activity and exercise that are not physical benefits.
4. List three activities or exercises you would suggest for someone who wants to become more active but has never exercised before.

After conducting your internet research and answering the set of questions above, use what you have learned about exercise and physical activity to make a plan for yourself. You will need to plan at least 60 minutes of physical activity per day for a period of three weeks. Each day, use the chart below to record the type of activities you plan to do, the activities you accomplish, and the amount of time spent on each physical activity. Your plan may include all kinds of different sports, exercises, and physical activities. You may include things that you already do in the course of a day, such as a sports practice. You may plan to walk or jog after school with a friend or family member. You may decide to try an activity that is new to you. Use your research to find new ways to improve your activity level.
