These components of fitness are as follows:

7. Physical Activity  Physical activity is any bodily movement produced by skeletal muscles that result in energy expenditure.  Regular physical activity is physical activity that is performed on most days of the week.  What are some benefits of regular physical activity? (hint: bell ringers)

8. What to Know about Exercises and Health-Related Fitness. There are 5 components of health related fitness: 1.Cardio respiratory Endurance 2.Muscular strength 3.Muscular Endurance 4.Flexibility 5.Body Composition

9. Components of Fitness 1. Flexibility- which is the range of movements of your joints.

10. Components of Fitness 2. Cardio respiratory Endurance- which is the ability of your heart, lungs, and blood vessels to send fuel and oxygen to your body’s tissues during vigorous exercise.

11. Components of Fitness 3. Muscular Strength- which is the greatest amount of work your muscles can do at a given time 4. Muscular Endurance- which is how well your muscles can keep performing over a period of time without undue fatigue.

12. Components of Fitness 5. Body Composition- which is the amount of fat tissue your body has compared to the amount of other tissues.

13. Studies have shown that developing many of these fitness components can improve the quality of your life.

14. Exercise has many positive effects on your body.  Heart Increased blood volume per heartbeat Increased blood circulation to the heart itself Decrease resting heart rate Decreased heart rate after exercise or hard work  Lungs Increased lung capacity Increased blood circulation Increased efficiency of muscles used in breathing

15. Exercise has many positive effects on your body cont’d.  Nervous System Decreased stress Improved coordination and reaction time  Muscles Increased blood circulation Increased size, strength, and endurance  Bones and Ligaments Increased strength of bones Increased strength of joint tissues

16. Exercise has many positive effects on your body cont’d.  Metabolism Improved regulation of body fats in bloodstream Improved regulation of blood sugars  Psychological Effects Better sleep Increased intellectual productivity Relief from stress

17. So, let’s start exercising!!  There are three components of an exercise session.  They include: The warm-up The work out The cool down

18. The Warm-up  Warming up is engaging in activity that prepares the muscles for the work that is come.  First, you should perform some type of activity slowly for about 5 minutes. (Ex: light jog)  Second, you need to stretch your muscles you plan on working.  Warming up allows your pulse rate to increase gradually.

19. The Work out  This is the component of your exercise program in which you are actually performing the activity.  Within the work out, there are guidelines that should be followed to reduce risk of injury and maximize the benefits: Frequency Intensity Duration

20. Frequency  Exercise conducted at regular intervals each week, continuing throughout the year…  Or time spent to improve fitness  A beginning workout should be scheduled three times a week, with no less than 1 day and no more than 2 days between sessions.

21. Intensity  The level of exertion during exercise. How hard one works.  It is very important not to overdo exercise!!  You MUST start slowly and build endurance  If using weights, start light and build toward heavier ones. In aerobics, work toward your target heart rate.

22. Duration  Length of time spent to improve fitness –How long one exercises

23. Set vs. Rep

24. Rep  Number of times a given resistance is performed Set  A group of repetitions of an exercise movement done consecutively, without rest, until a given number or fatigue is reached

25. Example If you were going to do bench press….  In the first SET, you did 100 lbs. ten times (10 REPS)  In the 2 nd SET, you did 110 lbs. Eight times (8 REPS)  In the last SET, you only did six REPS.

26. The Cool Down  Just as your body needs to be readied for increased activity. It needs to be returned gradually to a less active state.  During exercise, an increased amount of blood is pumped to the heart with the help of contractions of large leg muscles that push against the veins.  If the leg muscles relax suddenly, pooling may result.  The best way to cool down is to slow the activity.
