Five Areas of Health-Related Fitness
To have total fitness, you need to take into account the five
areas of health-related fitness.
• Cardiorespiratory endurance
• Muscular strength
• Muscular endurance
• Flexibility
• Body composition

Improving Fitness Through Exercise
When you know your strengths and weaknesses, you can take
steps to improve your physical fitness through exercise.
Lesson

Elements of Fitness
Measuring Cardiorespiratory Endurance
Cardiovascular health depends on maintaining good
cardiorespiratory endurance. The three-minute step test can be
used to measure your cardiorespiratory endurance.
Lesson
2
Elements of Fitness
Cardiorespiratory Endurance—Step Test
The step test enables you to determine the rate at which your
heart beats following a period of physical activity.
Lesson
2
Elements of Fitness
Measuring Muscular Strength and Endurance
• You need muscular strength for activities that involve lifting,
pushing, or jumping, and muscular endurance to perform
such activities repeatedly.
• People with good muscular strength and endurance often
have better posture and fewer back problems.
Lesson
2
Elements of Fitness
Abdominal Muscle Strength and Endurance—Curl-Ups
Curl-ups are often used to measure abdominal strength.
Lesson

Elements of Fitness
Upper Body Strength and Endurance—Arm Hang
The arm hang is one test that is used to measure upper body
strength and endurance.
Lesson
2
Measuring Flexibility
Being flexible can:
• Increase your athletic performance.
• Help you feel more comfortable, and
reduce the risk of muscle strains and
other injuries.

Elements of Fitness
Body Flexibility—Sit-and-Reach
You can use the back saver sit-and-reach test, developed by the
Cooper Institute of Aerobics Research in Dallas, Texas, to assess
the flexibility of your lower back and the backs of your thighs.
Lesson
2
Measuring Body Composition
• The “pinch test” is a common
method of determining body
composition.
• A skinfold caliper is used to
measure the thickness of fat on
three to seven different parts of the
body.
• The average of the measurements
is then calculated to estimate the
total proportion of body fat.

Categories of Physical Activities
You can choose from many different physical activities and
exercises to improve your fitness level, but most fall into one
of two categories:
1. Aerobic exercise
Examples: Running, cycling, swimming, and dancing
2. Anaerobic exercise
Examples: Running a 100-meter dash and lifting weights
Lesson
2
Improving Your Fitness
Improving Cardiorespiratory Endurance
• When you do aerobic exercises, your heart rate increases and
your heart sends more oxygen to your muscles to use as
energy.
• Don’t force yourself to continue an aerobic activity if you
become exhausted.
• Before beginning a fitness program, consult a health care
professional.
Lesson
2
Improving Your Fitness
• Improving Muscular Strength and Endurance
• Anaerobic exercises such as resistance training help tone
muscles, improve muscular strength, and increase muscular
endurance.
Lesson

Improving Your Fitness
Improving Flexibility
When you have good flexibility, you can easily bend, turn, and
stretch your body.
Lesson
2
Improving Your Fitness
Improving and Maintaining Bone Strength
• The health behaviors you engage in relating to physical
activity
• and nutrition can affect the health of your skeletal system
now and later in life.
• Calcium found in dairy products and certain green vegetables
is essential for building strong bones.
• Resistance training and weight-bearing activities can also
help increase bone mass and strengthen your skeletal
system.

and blood vessels to use and send fuel and oxygen to the
body’s tissues during long periods of moderate-to-vigorous
activity..
2. Muscular strength: The amount of force a muscle can exert.
3. Muscular endurance: The ability of the muscles to perform
physical tasks over a period of time without becoming
fatigued.
