Composition
Strength
Endurance
Building overall endurance and muscle endurance
can be achieved by spending more time doing a
chosen exercise or physical activity.
endurance The ability to perform difficult physical activity
without getting overly tired
muscle endurance The ability of a muscle to repeatedly
use force over a period of time
Endurance
You can build cardiovascular endurance by doing
aerobic exercises for 30 minutes at least three times
a week.
cardiovascular endurance The measure of how well your heart
and lungs work during moderate-tovigorous physical activity or exercise
Strength
The amount of work your muscles can do at a given
time is a measure of your strength.
strength The ability of your muscles to use force
By increasing strength, you lessen the chances of
getting lower back pain and hurting yourself when
lifting things.
Flexibility
You can increase your flexibility with regular, gentle
stretches.
flexibility The ability to move joints fully and
easily through a full range of motion
When you are flexible, you feel more comfortable and
will be less likely to injure yourself when you exercise
or play.
Types of Exercise
Most physical activities and exercises can be
described as aerobic exercise or
anaerobic exercise.
aerobic exercise Rhythmic, moderate-to-vigorous activity that uses
large amounts of oxygen and works the heart
and lungs
anaerobic exercise Intense physical activity that builds muscle but
does not use large amounts of oxygen
Effects of Body Composition on Fitness
Physical fitness is tied to body composition.
body composition The proportions of fat, bone, muscle, and fluid
that make up your body weight
If you exercise regularly, your body can gain muscle
and lose fat.
