Fitness Vocabulary
 Fold your paper “Hot Dog” style
 Tear 5 folds.
 Write the following terms on the outside
of each flap.
1. Obesity
2. Basal Metabolic Rate,
3. Sedentary
4. Aerobic Exercise
5. Anaerobic Exercise.
Fitness Vocabulary
 Obesity: Body weight that is 20% or more over
desirable weight.
 Basal Metabolic Rate (BMR): The number of calories
the body uses at rest. Metabolism.
 Sedentary: Inactive lifestyle
 Aerobic Exercise: Vigorous, rhythmic that improves
cardio-respiratory endurance and body composition.
 Anaerobic Exercise: Exercise in which the body’s
demand for oxygen is greater than what is available
during exertion.
Components of Fitness
 1. Flexibility: The range of movement of
the joints.
 2. Muscle Strength: The ability to exert force
against resistance. (The greatest amount of work
your muscles can exert at a given time).
 3. Muscle Endurance: The ability of muscles to
keep working over a period of time without
causing fatigue.
Components of Fitness
 Cardiorespiratory Endurance: The ability
of the heart and lungs to deliver needed
oxygen to the body during exercise.
 Quickly return to resting rate.
Body Composition
What is Body Composition?
 Body Composition is the percent of fat
to lean muscle, bones, connective tissue,
and water in the body.
 (Fat: Non-fat components)
How is Body Comp Tested?
 1. Using the “Body Mass Index” BMI.
 This is only based on height and weight
chart.
 Ineffective because muscle density is not
used or considered when tested.

 2. The “Skinfold Measurement” consists
 of: CALIPER the device used to measure
the skin.
– 3-9 sites on the body are tested for the
thickness of skin.
– More accurate than the BMI

3. Hydrostatic Weighing
 First, the dry weight is determined, then
the subject is submerged in water,
exhales out, and water weight is
determined.
 Most accurate way to calculate body
composition.
The 3 Body Types
 Ectomorph: Tend to have a delicate and
fragile body frame. Bones are light, joints
are small, and muscles slight. The limbs
and torso tend to be long and lean.
 Examples: Kate Moss, Lisa Kudrow, and
Seth Green.
Body Types continued..
 Mesomorph: has well-defined muscles
and large bones. Their bodies tend to
be muscular and athletic.
 Mesomorphs are able to gain muscle easily.
 Ex.: Bruce Willis, Sylvester Stalone.
Body Types Continued…
 Endomorph: Body tends to be round and
soft (lacking muscle). Weight tends to be
carried in the abdominal area.
 Examples: John Goodman, Roseanne,
and Jack Black, Bob Akers.
FIT or FAT
 In order to survive and have proper body
function, a person Must have fat on their
body.
 What is “Percent body fat”?
 The percentage of the total body that is Fat.
Where does body fat come from?
 Fat is produced by the body when an
excess intake of calories occurs.
 Calories taken into the body first go to
the body’s overall maintenance and it’s
current level of physical activity. The
excess energy is stored in the form of
body fat.
How do you lose excess fat?
 By burning more energy than an individual is
in-taking.
 The extra stored energy (fat) in the body will
be broken down for physical activity.
Why do gains in weight always seem
to go to the same place?
 A person’s body deposits fat according to
their genetic code.
 Women typically store fat in thighs, waist,
and hips.
 Men typically store fat in their abdomen.
Essential Fat
 Required for normal physiological
functioning. It consists of fat stored in bone
marrow, heart, lungs, liver, etc. (9% more in
women for birth)
Storage Fat
 Accumulated in adipose tissue and acts as
an insulator for heat provides energy for
metabolism, and adds protection and
padding for organs.
