Section 13.1 The Importance of Physical Activity
Objective
Describe the five types of physical activity.
Section 13.1 The Importance of Physical Activity
Types of Physical Activity
• Physical activities can be classified as
1) aerobic exercise or
2) anaerobic exercise.
• Strengthening and endurance activities can be
further classified as
1) isometric exercise,
2) isotonic exercise, or
3) isokinetic exercise.
Section 13.1 The Importance of Physical Activity
Aerobic Exercise
• Ongoing physical activity that raises your
breathing rate and heart rate is called aerobic
exercise

Aerobic
increase the amount of oxygen
that your body takes in and uses.
Section 13.1 The Importance of Physical Activity
Aerobic Exercise
• Examples: Swimming, running, brisk walking, and
cross-country skiing are all forms of aerobic
exercise.
Section 13.1 The Importance of Physical Activity
Anaerobic Exercise
• Intense physical activity that lasts for a few seconds
to a few minutes is called anaerobic exercise.
• Most anaerobic exercises develop muscular
strength, muscular endurance, or flexibility.
Section 13.1 The Importance of Physical Activity
Anaerobic Exercise
• Examples: Lifting weights, doing push-ups, and
sprinting are examples of anaerobic activities.
Section 13.1 The Importance of Physical Activity
Isometric Exercise
• Isometric exercise (eye suh MET rik) is an exercise in
which muscles contract but very little body movement
takes place.
• If you do isometric exercises on a regular basis, the
muscles you use will become stronger.
Section 13.1 The Importance of Physical Activity
Isometric Exercise
• Examples: planks, pushing against a wall, climbing, mountain biking
and motocross (grip and upper body strength), Judo, wrestling,
gymnastics and horseback riding
Section 13.1 The Importance of Physical Activity
Isotonic Exercise
• Isotonic exercise (eye suh TAHN ik) involves
contracting and relaxing your muscles through
the full range of a joint’s motion.
• Through repetition of isotonic exercises, you can
develop muscular strength and endurance.
Section 13.1 The Importance of Physical Activity
Isotonic Exercise
• Examples: Pull-ups, exercises with free weights
(such as biceps curls, bench press, leg extensions,
incline press, squats)
Section 13.1 The Importance of Physical Activity
Isokinetic Exercise
• In isokinetic exercise (eye soh ki NET ik) muscles
contract at a constant rate.
• These exercises are often used as therapy to
rebuild muscle strength after an injury.
Section 13.1 The Importance of Physical Activity
Isokinetic Exercise
• Examples: fitness machines (stationary bike, bench
press machine)

Class Activity – Charades
Instructions: Students will volunteer to act out a
physical activity. The class will try to guess which
physical activity you are doing and will raise their
hand to answer. Students will then have to decide
which type of physical activity the student acted
out and which components of health-related fitness
is involved in performing that activity.
