Fitness
The ability to carry out daily tasks
easily & have enough reserve energy
to respond to unexpected demands.
Five Areas of Health Related
Fitness…






1. Cardio Respitory Fitness
2.Muscular Strength
3.Muscular Endurance
4.Flexibility
5.Body Composition
(Core Strength)
1. CARDIORESPITORY
ENDURANCE

the ability of your body to continuously
provide enough energy to sustain
submaximal levels of exercise.

Speeds up fat metabolism
Improves delivery of oxygen (capillarization)
Faster removal of waste products

Decreased levels of stress

2. MUSCULAR STRENGTH






Strength is defined as the ability of a
muscle to exert a force to overcome a
resistance.
Avoid injuries
Maintain good posture
Remain independent (in older age)
TESTS: Push-Up Test, Pull-Up Test, 1RM/5Rm
“Relative Strength vs. Absolute Strength
3. MUSCULAR ENDURANCE



Muscular endurance, unlike strength, is
the ability of a muscle to make
repeated contractions over a period of
time.
Ability to sustain low to moderate activity
used in day-to-day life in activities such as climbing stairs,
digging the garden and cleaning.
4. FLEXIBILITY
The ability to move a body part through a
full range of motion.
Especially important in the posterior chain and lower body.
Back Problems,
Knee Problems
Running mechanics & gait
Tests: Sit & Reach
4. FLEXIBILITY/MOBILITY
Flexibility: The maximum static range of
motion. (passive)
Mobility: The ability to move a joint part
through a full range of motion.
Especially important in the posterior chain and lower body.
Back Problems,
Knee Problems
Running mechanics & gait
Tests: Sit & Reach
Improving Flexibility/Mobility

Dynamic Stretching (Mobility)
Static Stretching (Flexibility)
(PNF Stretching)

5. BODY COMPOSTION
The amount of lean body mass (all tissues other
than fat, such as bone, muscle, organs &
body fluids) compared with the amount of
body fat. A healthy body comp involves
having a healthy balance between the two.
The Problem with BMI

NOT A DIRECT MEASUREMENT OF FAT

FAT OVERESTIMATION OF ATHLETES


FAT UNDERESTIMATION OF THIN AND
ELDERLY PERSONS
% Body Fat best assessment relative to health

Aerobic Exercise any activity that uses:
1. large muscle groups

2. is rhythmic in nature


3. can be maintained continuously for at least 10
minutes three times a day or for 20-30 minutes at
one time





Examples:
Running
Cycling
Swimming
Dancing
Anaerobic Exercise

Intense short bursts of activity in which the muscles
work so hard that they produce energy without using
oxygen.

Examples:

Running a 100 meter dash

Lifting weights

trains muscles to exert maximum force
in the shortest amount of time possible.

Exercise Program: 3 parts

PART 1. Warm-up: an activity that
prepares the muscles for work.

Brisk walk to increase body temp then
slowly stretch large muscles.
Program Continued…





PART 2. Workout: the workout should
follow the F.I.T.T. principle.
F= Frequency
I= Intensity
T=Time
T= Type
FrequencyNumber of times per week an activity
is performed – USE to be 3 times a week–
now CDC & ACSM recommend:
FOR SUBSTANTIAL HEALTH
BENEFITS ADULTS NEED:
2 hrs & 30 min (150 min) each week of MODERATE
INTENSITY aerobic activity
OR
1 hr & 15 min (75 min) each week of VIGOROUSINTENSITY aerobic activity
Aerobic activity should be performed for at LEAST 10
min AT A TIME, spread throughout the week
CDC RECOM CONT’D


Muscle strengthening activities - adults:
2 or more days a week


All major muscle groups should be worked.
Legs, hips, abs's, chest, shoulders & arms
Exercises for each muscle group should be
repeated 8-12 times per set. As exercises
become easier, increase the weight or do
another set
F.I.T.T. CONTINUED
Intensity an activity performed between
60-90% of maximal HR. Begin slowly to
build endurance. Doing too much too
soon is harmful.
MaxHR - widely used method to determine
exercise intensity.
Karvonen Formula
Used to calculate Target Heart Rate
220 minus age in yrs equals a predicted HR max in
beats per minute
An intensity of between 60-90% -- Target HR
SEE KARVONEN FORMULA HANDOUT IN PACKET –
Copy the calculation on a new sheet of paper & turn
this in for x-credit
See Target HR chart for children age 7-12
New HR Calculation for
Women





Karvonen based on studies of men
New 206 minus 88% of age
Old formula example “at age 50 gives a
170 bpm for men & women”
Before women had a hard time meeting
their target HR
New calculation is more difficult –

HEART FACTS



Did you know………
The heart pumps 2,000 gallons of blood
through about 60,000 million miles of
blood vessels
It the heart beats 100,000 times a day
year after year ---- it never rests!
Resting Heart Rate

The number of times your heart beats in one
minute when you are not active.




An average fitness level– 72-84 beats/minute
4 weeks of participation in a fitness program can
reduce resting heart rate– 5-10 beats per minute
RHR taken immediately in the am upon waking
RHR decreases as heart becomes a more fit
muscle.
How to Measure Heart Rate



Find pulse @ carotid or radial artery by
counting the # of times the heart pulses
or beats in a minute.
Use first 2-3 fingers not thumb
Do not use excessive pressure – could
simulate receptors to slow HR
HR Measurement




Count for 10 seconds X 6
OR
15 seconds X 4
3 minutes after exercise count again –
the closer that reading is to resting HR
the better your condition
INTENSITY TEST

Talk Test - you should be able to
breathe comfortably & string a couple
of words together throughout aerobic
exercise. More pleasurable than gasping
for air.
MODERATE INTENSITY


Can talk, but not sing during activity
TYPES OF AEROBIC ACTIVITY:





Brisk walking (3 miles per hr or faster but
not race walking)
Water Aerobics
Bicycle riding slower than 10 mph
Tennis doubles
Ballroom dancing
General gardening
VIGOROUS INTENSITY

CANNOT SAY MORE THAN A FEW
WORDS W/O PAUSING FOR BREATHS






Race walking, jogging or running
Swimming laps
Tennis singles
Aerobic dancing
Bicycling 10 miles or faster
Heavy gardening Hiking uphill
CDC GUIDELINES 6-17 yrs




EVERY DAY – 1 hr or more of phy activ
AEROBIC ACTIV –Most of the 1 hr a day
either mod or vigorous intensity –
vigorous intensity at least 3 days a
week
MUSCLE STRENGTHENING on at least 3
days a week
BONE STRENGTHENING on at least 3
days a week. Activities produce a force
on the bones that promotes bone
growth & strength through impact with
“FITT” CONTINUED:
Time/ DurationContinuous & sustained physical activity 2060 minutes or more.
Work @ moderate-intensity activity for 30 minutes or more on
5 or more days per week OR vigorous-intensity for 20 or
more minutes on 3 or more days.
Type Devote 75-80% of workout to aerobic activity—20-25%
to anaerobic/ a combo of both.
Aerobic is recommended - jogging, swimming, x-c skiing,
bicycling, brisk walking & dancing.
Workout Program Continued…

PART 3. Cool Down: an activity that
prepares the muscles to return to a
resting state. First slow down the
activity for around 5 minutes then
stretch.
Hints…FOR EXERCISE
ADHERENCE
1.
2.
3.
4.
5.
Put it into your daily schedule– make
it a habit.
Find a constant time
Exercise with a friend
Choose an activity/activities that you
enjoy
Mix it up
Additional Fitness Information

Hydration: is taking in fluids so that the
body functions properly. Before,
during, and after exercise

Adequate hydration results in :



More alert & focused
Reaction time quicker– muscles respond more
quickly and less likely to cramp
Endurance is greater
