EXERCISE AND FITNESS Note: This power point presentation was created originally by McGraw Glencoe Health company. It was downloaded from their free educator’s website then revised by Todd Corabi Physical Activity and Health In this lesson, you will Learn About… The benefits of physical activity. How to increase your strength, endurance, and flexibility. Physical Activity and You Physical activity is any kind of movement that causes the body to use energy. Participating in regular physical activity: Helps build and maintain healthy bones, muscles, and joints. Helps control weight and reduce fat. Helps keep blood pressure within a healthy range. You should be physically active 30-60 minutes DAILY Physical Activity and You (cont’d.) The ability to handle the physical work and play of everyday life without becoming tired is known as fitness. Exercise can help you become more fit. Daily physical activity also has MANY other benefits in all areas of one’s self (wellness) Physical Activity and Your Total Health Benefits to physical health: Maintenance of a healthy weight Improved strength and flexibility Better performance of heart and lungs Decreased risk of certain diseases Physical Activity and Your Total Health (cont’d.) Benefits to mental/emotional health: Enhanced self-confidence Sharpened mental alertness Reduced stress More relaxed attitude More enjoyment of free time Physical Activity and Your Total Health (cont’d.) Benefits to social health: Additional chances to meet new people Opportunities to share common goals with others Increased ability to interact and cooperate with others Opportunities to use talents to help others Components of Exercise= Strength The first element of fitness is strength, the ability of your muscles to exert a force. It is measured according to the most work the muscles can do at a given time. Strength (cont’d.) Building strength through physical activity enables you to: Lift heavy objects more easily with less chance of injury. Develop skills for sports and other activities. Components of Exercise = Endurance The second element of fitness is endurance, the ability to perform vigorous physical activity without getting overly tired. There are two basic types of endurance: Heart and lung endurance (usually referred to as “cardio”) Muscular endurance Endurance (cont’d.) Heart and lung endurance is the measure of how effectively the heart and lungs work during moderate-to-vigorous physical activity or exercise. Muscle endurance is the ability of a muscle to repeatedly exert a force over a prolonged period of time. Endurance (cont’d.) Two types of exercise can help build endurance: Aerobic exercise—Rhythmic, nonstop, moderate-to-vigorous activity that requires large amounts of oxygen and works the heart. Anaerobic exercise—Intense physical activity that requires little oxygen but involves short bursts of energy. Endurance (cont’d.) People should do moderate heart and lung activity at least 30 minutes daily to best way to build or maintain heart and lung endurance. Examples of aerobic exercises: Walking, jogging, and bicycling Swimming laps Cross-country skiing Endurance (cont’d.) Anaerobic activities help build and maintain strength and muscle endurance. Examples of anaerobic exercises: Weight lifting Sprinting Components of Exercise = Flexibility The third element of fitness is flexibility, the ability to move joints fully and easily. You can increase your flexibility by doing regular, gentle stretching of muscles and joints. Research Improving flexibility reduces the risk of injury during strength or endurance training. Stretching Exercises There are different schools of thought concerning Flexibility exercises. Recently, there has been debate as to the “best way” to stretch. However, there are basically, 2 healthy kinds of stretches: Stretching Exercises 1st kind of stretching = STATIC stretching Holding a stretch of a muscle for 15-25 seconds Done after a brief warm up of the muscles to help prevent injury during exercise Done after exercise during cool down to increase flexibility Stretching Exercises 2nd kind of stretching = Dynamic Sports Related Slow movements of a joint through a range of motion that mimic movements done in sports OR prepare the bodo to do certain other exercises Done prior to participating in a sports activity OR as part of a training program There are 3 main ways to exercise no matter what exercise component you are targeting (cardio, muscular endurance, muscular strength, flexibility) Interval Continuous Circuit INTERVAL EXERCISE Exercise that changes pace OR starts and stops often Examples include: Baseball, Football, Soccer, Basketball Training examples in running would be walk 5 minutes, jog 5 minutes, walk 5 minutes Interval training is most often associated with cardio activities CONTINUOUS Exercise Continuous exercise is exercise that goes at a continued pace for an extended period of time Examples are running long distances and swimming Circuit Training Circuit Training is a variety of exercises done in a relatively short time to target a variety of muscle groups quickly Usually, there is a mix of cardio, muscular strength, muscular endurance and flexibility exercises in circuits Also known as stations Rule of thumb, no longer than 2 minutes at one station and no longer than 10 seconds rest between stations Selecting the Right Exercises To reach your fitness goals, plan a program that is: Convenient. Affordable. Enjoyable. Workouts should include a variety of physical activities to promote balanced fitness. Selecting the Right Exercises (cont’d.) To add physical activity to your life: Do a variety of aerobic exercises and/or active sports and recreation activities for at least 20 minutes, three to five times a week. Aim to do strength and flexibility exercises two or three times a week. Try not to spend too much time watching television, online, or playing non-active video games. Staying active is important for good health.
