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
Four Major Health Related Components to Fitness
1.
Flexibility – the ability to move joints and use
muscles through their full range of motion.
Examples:
Stretching, Sit and Reach, Yoga
2. 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.
Examples:
With repetition: Push-ups, Sit-ups, Pull-ups, Crunches
True muscle endurance exercises require the same muscle
movement repetition (you can’t do just one): running,
jogging, swimming, bicycling
3. Muscle Strength – the ability of a muscle to
exert force for a brief period of time.
Example:
Weight lifting
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
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.
4. 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.
