Fitness and You
Vocabulary
Cardiorespiratory Endurance – The ability of the heart,
lungs, and blood vessels to utilize and send fuel and
oxygen to the body’s tissues during moderate to
intense exercise.
Muscular Strength – the amount of force a muscle can
exert.
Muscular Endurance – The ability of the muscles to
perform physical tasks over a period of time without
becoming fatigued.
More Vocab
Flexibility – The ability to move a body part
through a full range of motion.
Body Composition – The ratio or percentage of
body fat to lean body tissue (muscle bone,
water, etc.)
Exercise – Purposeful physical activity that is
planned, structured, and repetitive and
maintains person fitness.
Improving Your Fitness
Aerobic Exercise – Any activity that uses large
muscle groups, is rhythmic, and can be
maintained for at least 10 minutes three
times a day or 30 minutes once a day
(running, swimming).
Anaerobic Exercise – Intense short burst of
activity which the muscle work so hard that
they produce energy without losing oxygen
(100 meter dash).
The relationship among body
composition, diet, and fitness.
A nutritious balanced diet and regular
physical activity will help maintain a
healthy body composition.
Effects of resistance training on
the muscular and skeletal
systems.
It improves muscular strength and
endurance and strengthens bones.
Benefits of Aerobic Exercise


Strengthens the heart muscle which allows
it to pump more efficiently.
Increase lung capacity.
Target Heart Rate

Turn to page 84 in your book and
complete Real Life Application on Target
Heart Rate. Do not do the activity, just
find your target heart rate calculations
How to improve flexibility?
Stretching exercises – move slowly and
gently.
How to improve and maintain
bone strength


Calcium – found in dairy products and
green veggies.
Resistance training – walking and stair
climbing force you to work against gravity.
Types of Resistance Training



Isometric Exercise – Tension is used to
improve muscular strength with little to
no movement (pushing on a wall)
Isotonic Exercise – Muscles contract
and movement is repeated (push ups)
Isokinetic Exercise – Resistance is
moved through an entire range of
motion at a controlled speed (treadmill)
