FITNESS AND STRESS RELATIONS
Why would we study exercise and stress in the
same unit?
 What aspects of development are they related to?
 What is exercise?
 What counts as exercise?
 Physical activity?

BENEFITS OF REGULAR EXERCISE
Improves:
bone mass, cholesterol levels, appearance, weight control,
energy, confidence, mobility (especially for people with
arthritis), stress
Decreases risk of:
depression, blood clots, osteoporosis, stroke, hypertension,
colon cancer, falls for elderly, senility, type II diabetes,
heart disease
BENEFITS OF REGULAR EXERCISE?

Term to know- Endorphins
Decreased risk for disease
 Improved mood, looks, less risky behaviors, etc….

FOUR MAJOR HEALTH RELATED
COMPONENTS TO FITNESS:
Flexibility
– the ability to move joints and use
muscles through their full range of motion.
Examples:
Stretching, Sit and Reach, Yoga, Hockey,
Gymnastics, Cheer, Sit and stretch
1.
Muscle Endurance –
the ability of a muscle, or a group of muscles, to
sustain repeated contractions or to continue
applying force against a fixed object. Use same
group of muscles over and over.

Examples: With repetition: Push-ups, Situps, Pull-ups, Crunches
True muscle endurance exercises require the
same muscle movement repetition (you can’t
do just one): running, jogging, swimming,
bicycling
2.
3.

Muscle Strength – the ability of a muscle to
exert force for a brief period of time.
Example: martial arts, weight lifting, monkey bars,
pull up, Water ski, gymnastics ( bars)
4. Cardiovascular (Cardiorespiratory) Endurance – the ability of
the circulatory and respiratory systems (heart, blood vessels,
and lungs) to deliver oxygen and fuel to working muscles
during exercise and sustained physical activities.
This component is most important to lifetime wellness because it
keeps the heart healthy.
Examples:
 Running, swimming, Biking
 Hiking
 Swimming
 Running
 Skating
SKILL RELATED COMPONENTS TO FITNESS
Successful athletic participation tends to involve most of these
components:
1.
Speed – the ability to move quickly from one point to another
2.
Agility – the ability of the body to change direction quickly &
accurately.
3.
Balance – the ability to maintain equilibrium while stationary or
moving.
Coordination – the ability to combine the senses with the body
parts to perform activities smoothly and accurately (hand – eye,
foot – eye).
5.
Reaction Time – amount of time it takes to get moving in
response to a stimulus.
6.
Power – the ability to transfer energy into force at an explosive
pace (hitting a ball, jumping).
Resting Heart Rate (R.H.R.) -- the speed at which your heart
beats when you are at rest.
For accuracy, take your pulse for 1 full minute before you get
out of bed in the morning (bladder should be empty). Repeat for
a few mornings and take the average of those counts.
Maximum Heart Rate (M.H.R.) – the fastest your heart is
capable of beating safely.
Figuring Maximum Heart Rate:
220 – your age = M.H.R.
Ex: For a 15 year old….
220 – 15 = M.H.R. of 205 bpm (beats per minute)
Do NOT exceed Maximum Heart Rate!
Target Zone Heart Rate – The heart rate you should try
maintain during an aerobic workout. This is
rate at which your heart muscle gets a good
workout, safely.
60 to 80 % of Maximum Heartrate
For beginners who are in good health, but just
starting to workout, or working out on an
irregular basis, target zone is about 60% of your M.H.R.
People who are healthy, work out 3 or more times per week,
and workout regularly for a few
months may increase their target zone to
80% of their M.H.R.
Estimating Target Zone Heart Rate:
For beginners: M.H.R. x 60% = Target Zone Heart
Rate
Example: 205 x .60 = 123 bpm
(For 15 year old)
For advanced: M.H.R. x 80% = Target Zone Heart
Rate
Example: 205 x .80 = 164 bpm
(For 15 year old)
Exercise Program:
A safe and well planned cardiovascular exercise
program should consist of :
Stage 1: 5 – 10 min. warm-up activity
examples: stretching, light jogging
Stage 2: 20 – 30 min. stimulus activity - target zone
examples: aerobics, running, zumba
Stage 3: 5 – 10 min. of cool down activities
examples: stretching, floor exercises,
flexibility activities, slower-paced exercises
Lactic acid builds up in muscles during
exercise. It is followed by production of other
metabolites, which may result in Delayed
Onset Muscle Soreness (DOMS).
For cardiovascular improvement, you should exercise at least
3 – 5 times per week, with 20 - 30 minutes per workout at
your target zone rate.
It takes 3 - 6 months of consistent workout to make a big
improvement in fitness level.
When workout routines stop,
muscles begin to lose tone.

Body Mass Index* – BMI – the measure of body fat based
on height and weight. You can check yours at the Centers
for Disease Control (CDC) website at
http://www.cdc.gov/healthyweight/assessing/
bmi/childrens_bmi/about_childrens_bmi.html
*Keep in mind that BMI does not take frame size or lean
muscle percentage, or waist to hip ratio, which all play a
role in determining probability of overall health.
Normal Range of Body Fat
(for adults over the age of 23):
Men = 7 – 15%
20% or higher = obesity
Women = 20 – 25% 30% or higher = obesity
Obesity is defined as having too high a ratio of body fat
compared to body muscle.
Is obesity about how much one weighs?????
NO… it is about lack of fitness!
New Research
BAI – Body Adiposity Index is being tested as a more
accurate way to assess body composition than BMI (body
mass index). BAI considers height and hip measurements,
not just the height to weight comparison of BMI.
Where a body stores excess fat is more important in terms of health risks
than just weight. BAI addresses that.
