1. Fitness and You

2. Elements of Fitness
Cardiorespiratory endurance – the ability of the heart, lungs, and blood vessels to utilize and send fuel and oxygen to the body’s tissues during long periods of moderate-to-vigorous activity
Muscular Strength – the amount of force a muscle can exert
Muscle Endurance – the ability of the muscles to perform physical tasks over a period of time without becoming fatigued

3. Elements of Fitness
Flexibility – the ability to move a body part through a full range of motion
Body composition – the ratio of body fat to lean body tissue, including muscle, bone, water, and connective tissue such as ligaments, cartilage, and tendons

4. How Do You Improve Those Elements?
By knowing your strengths and weaknesses, you can take steps to improve your physical fitness through __________.
Exercise – purposeful physical activity that is planned, structured, and repetitive and that improves or maintains personal fitness
EXERCISE

5. Why is Each Element Important?
Cardiorespiratory Endurance
Cardiovascular disease is the leading cause of death in the U.S.
By keeping the cardiovascular system healthy, you reduce the risk of developing this life-threatening disease.

6. Why is Each Element Important?
Muscular Strength and Endurance
These elements give you the necessary power to carry out your daily tasks without becoming fatigued.
More likely to have better posture and fewer back problems.

7. Why is Each Element Important?
Flexibility
Flexibility can increase your athletic performance, help you feel more comfortable, and reduce the risk of muscle strains and other injuries.
Flexibility also can help prevent lower back problems.

8. Why is Each Element Important?
Body Composition
Improving body composition improves the way you look and feel, helps you avoid the health problems of being overweight, and reduces stress on the skeletal system.
Males > 25% body fat / Females > 30 % body fat
- At risk of developing cardiovascular problems

9. Improving Your Fitness
Most exercises fall into two categories – aerobic or anaerobic
Aerobic – any activity that uses large muscle groups, is rhythmic in nature, and can be maintained continuously
Anaerobic – intense short bursts of activity in which the muscles work so hard that they produce energy without using oxygen

10. Improving Your Fitness
Improving Cardiorespiratory Endurance
Aerobic exercise increases heart rate
Heart pumps more oxygen to muscles
As the heart muscle strengthens, it pumps blood more efficiently
Increases the lungs’ capacity to hold air

11. Improving Your Fitness
Increasing Muscular Strength and Endurance
Anaerobic exercises such as resistance and strength training builds and strengthens muscles
Keeps blood sugar and cholesterol levels normal

12. Improving Your Fitness
Improving Flexibility
Regular stretching exercises
Improving and Maintaining Bone Strength
Calcium
Weight-bearing exercises/resistance training
Bone mass begins to decline during a person’s late twenties and early thirties
