5 areas of health related fitness.

Body Composition, Flexibility, Muscular Strength, Muscular Endurance, Cardiorespiratory Endurance.

Body Composition

Ratio of body fat to lean body tissue. Includes muscle, bone, water, and connective tissue. Measured using skin calipers. The skin and underlying layer of fat are pinched together and compared using a chart.

Flexibility

The ability to move a body part through a full range of motion. Important because it helps reduce muscle strains and lower back problems.

Muscular Strength

The amount of force a muscle can exert. Good _______ ________ allows you to perform daily tasks more efficiently. Helps you conserve energy. Enables you to get more things done in a typical day Measured by number of push-ups, and sit-ups you can do.

Muscular Endurance

The ability of the muscles to do difficult physical tasks over a period of time without causing fatigue. People with good _______ ________ generally have better posture = fewer back problems. Better able to resist fatigue.

Cardiorespiratory Endurance

The ability of the heart, lungs, and blood vessels to send fuel and oxygen to the body’s tissues during long periods of vigorous activity. Can be measured by finding your pulse recovery rate or using the 3 minute step test.

How does exercise benefit physical health?

• By building a strong body

• Helps reduce the feeling of chronic fatigue and stiffness

• Improves motor responses

• Strengthens body’s muscles, skeleton, and other moving parts

• Slows the onset of osteoporosis (disease where bones become brittle and weak)

• Enhances body’s protection against disease

• A strong, toned body is capable of recuperating and restoring itself more quickly following illness

• Exercise improves the functioning of certain body systems.

Nervous System - improves your reaction time

Circulatory System - strengthens heart allowing it to pump blood more efficiently

Respiratory System - works more slowly and efficiently so you take fewer deeper breaths

• Increases lung capacity

Exercise and weight control

Main cause of obesity is overeating and sedentary lifestyle.

Sedentary Lifestyle
