Announcer: Exercise is the single most important change that you can make to reduce your chances of falling. Regular exercise will improve your health and mood, give you more energy, help you sleep better, and make it easier to do everyday tasks that are important to you. It will help to prevent falls by improving your strength, balance, and walking ability. The Surgeon General recommends that you try to do 30 minutes of cardiovascular exercise five days a week. This can be divided into 10-minute periods throughout the day. Did you know that an effective exercise program includes not only cardiovascular exercises like walking or swimming, but also exercises to improve your strength and balance? Exercises to improve your muscle strength such as knee extensions should be done two times a week, and don't forget to exercise for balance. Examples of these exercises include heel-to-toe walking and standing on one foot. Research has also shown that tai chi and yoga are both group exercises that can help increase balance. Balance is like any other motor skill. It improves with practice. If you have not exercised in a long time and have any health-related concerns, be sure to see your doctor before beginning any exercise program. Your doctor may recommend that you work with a physical therapist to learn what exercises you can do to reduce your chances of falling.
