Metabolism
• The process in which your body
gets energy from the food you
eat
• (How fast your body burns /
stores the food you eat)
Basal Metabolism
• The minimum amount of energy
required to maintain life
processes in the body
• (Least amount of food you need
to survive)
Calories
• Energy value in food, measured
in units of heat
• Increased exercise = increased
calories burned = loss of weight
• 1 pound fat = 3,500 calories
Aerobic exercise
• Vigorous activity in which
oxygen is continuously taken in
for a period of at least 20
minutes
• Oxygen is continuously being
sent to the muscles while
exercising
Aerobic examples…
•
•
•
•
Jogging
Swimming
Cycling
Brisk walk
• Strengthens heart and lungs to
work more efficiently
Anaerobic exercise
• Intense bursts of activity in which
the muscles work so hard that they
produce energy without using oxygen
• Your muscles are using the oxygen
already stored in your body, no new
oxygen being utilized
Anaerobic examples…
• Sprinting
• Weightlifting
• Strengthen muscles over time
Types of resistance
training
1. Isometric
2. Isotonic
1. Isokinetic
Isometric
• Activity that uses muscle
tension to improve muscular
strength with little or no body
movement
• Ex: Palms against each other
Isotonic
• Activity that combines muscle
contraction with repeated
movement
• Ex: Push / Sit / Pull – ups
Trunk twists
Isokinetic
• Activity that involves resistance
through an entire range of motion
• Increases joint flexibility
• Hammer strength machines

Planning a fitness program
– Before you actually exercise, make
sure you are physically able to
exert yourself.
– What if you have…
• Asthma ?
• Bad knee ?
• Sore back ?
Begin gradually
• Ease your way into your workout
program

exercises that you enjoy
Selecting the right activity

Where you live
Your interests
Level of health
Time and place
Personal safety
Do my activities meet the five
components of fitness?
Basics of a program…
#1) Overload
– Working the body harder than it is
normally worked
– Increase reps, weight, time,
distance
Basics cont…
#2) Progression
- Gradual increase in overload
necessary for achieving higher
levels of fitness
- Gradually adding more weight,
distance etc…
Basics cont…
#3) Specificity
– Particular exercises and activities
improve particular areas of health
related fitness
– Different activities / exercises for
different goals
Injuries
• Eventually going to happen
• You must determine the severity
of your injury
Injuries cont…
• If your injury requires medical
attention, seek it a.s.a.p.
or
If your injury is not getting better
within a week or so
What to do?
• R.I.C.E. Principal
• General first aid for the
sprain, strain, sore
muscle etc.
R.I.C.E.
• Rest
• Rest the injured body part or
your entire body. By doing so,
you are probably not going to
aggravate your injury more than
it already is, thus promoting
healing
R.I.C.E.
• Ice
•Apply ice to your injured
body part a.s.a.p. after you
injure it. This will keep the
swelling down. Ice
frequently until injury is
healed
R.I.C.E.
• Compression
•Wrap your injury with an ace
bandage to keep swelling
down. This will allow new
blood cells to heal your
injury faster
R.I.C.E.
• Elevation
•Elevate your injured body
part higher than your heart.
This will help drain the
blood, keeping swelling to a
minimum. This is important
at night!
