The
Dimension
of Physical
Cardiovascular Endurance
Cardiovascular endurance is your
body’s ability to keep up with exercise
like running, jogging, swimming,
cycling, and anything that forces your
cardiovascular system (lungs, heart,
blood vessels) to work for extended
periods of time. Together, the heart
and lungs fuel your body with the
oxygen needed by your muscles,
ensuring that they have the oxygen
needed for the work they are doing.
The Cooper Run (running as far as
possible in 12 minutes) is a test
commonly used to assess
cardiovascular endurance, but many
trainers
Muscular
EnduranceEndurance is the ability of your
muscles to perform contractions for extended
periods of time. Rather than just lifting or
carrying something for a few seconds, the
muscles are used for minutes. The way to
increase strength is to train with light weights,
working in the 20 – 25 rep range. Working with
lighter weight will train the muscle fibers needed
for muscular endurance, and the higher rep
range leads to a longer period of exercise.
Body Fat Composition Body fat composition
refers to the amount of fat on your body. For
example, a 100-pound person with a 25% body
fat composition will have a lean body mass of 75
pounds. To qualify as fit: - Men must have a body
fat composition lower than 17 percent Women
must have a body fat composition lower than 24
percent. The average man tends to have about
18 to 24 percent body fat, while the average
woman has 25 to 31 perc
Flexibility is one of the most important, yet
often overlooked, components of physical
fitness. Without flexibility, the muscles and
joints would grow stiff and movement would
be limited. Flexibility training ensures that your
body can move through its entire range of
motion without pain or stiffness. To test your
flexibility, lean forward and try to touch your
toes. Those with good flexibility will usually be
able to touch their toes, while those with
limited flexibility will not. The sit and reach test
(sitting on the floor and reaching toward your
toes) is another good way to assess your
flexibility. The more flexible you are, the closer
you will come to touching your toes and
beyond.
Muscular StrengthThis is the “power”
that helps you to lift and carry heavy
objects. Without muscular strength,
your body would be weak and unable to
keep up with the demands placed upon
it.
