FITNESS
Exercise
Exercise Benefits The most dramatic benefit of
exercise is to the heart and blood vessels. The more
active people are the less likely to develop heart
disease. Also, exercise requires less pumping from the
heart to supply oxygen to those muscles. An exercised
body also allows the heart to pump less rapidly while
at rest. A body in good shape tells the heart to take
it easy when the heart is resting, causing less wear
and work on the heart muscle. Exercise also helps
cholesterol to move out of the body rather than
sticking on the artery walls and tissues. Exercise
also tends to make a person more stable mentally,
decreasing or eliminating major mood swings and of
course exercise reduces body fat and improves the
physical appearance of people, which also improves
self-confidence and mental attitude.
Non-Exercise Dangers
People who have not maintained physical fitness
through a regular vigorous program are more likely to
develop certain problems. Their heart and lungs are
more prone to disease. Unexercised weak muscles put
extra strain on joints and ligaments. Regular exercise
will keep joints, ligaments, and muscles flexible and
less likely to strain. Vigorous exercise also has been
shown to have psychological benefits too. People who
exercise regularly usually sleep better, wake up
happier and are better able to concentrate and
perform. People who don't exercise and keep themselves
physically fit may wake up one day and be very
dissatisfied with their life and body. Fortunately,
it's never too late to start with some type of
exercise program. Check with your doctor for the
correct exercise program to meet your needs.
Dynamic Versus Static Exercise
We're going to increase your vocabulary today by
telling your about two types of exercises: dynamic and
static. If you swim, jog or take an aerobic dance
class, you're involved in a dynamic exercise. That's
because all those activities involve many muscle
groups with different movements and they all
strengthen your heart and lungs. Static exercise
usually involves staying in a single position and
exercising just one group of muscles. Weigh lifting is
a good example of static exercise. It helps you build
muscle strength and size but it does not do much for
your heart and lungs. For the best exercise program,
get involved in both dynamic and static exercise. The
static portion can help you shape a good looking body
and the dynamic part will help you shape a good
looking cardiovascular system. Now you have the best
of both worlds.
Exercise Sessions
The desire to improve yourself is the first step to
physical fitness and the next step is to begin a
fitness program. Any fitness program should begin with
a trip to the doctor. A doctor will examine your heart
and test your fitness level and then recommend an
exercise that's right for you. Once you begin
exercising, you should start with 20 minutes at a
time, three times a week. After performing at this
level for two weeks, increase the workout to four
times per week. You'll need to remember you'll have to
make some changes to your diet. It's a good idea to
increase the amount of protein to help build muscle
and increase carbohydrates for energy. You should cut
down on fats and sugars as these often do more to hurt
than to help. Once you've begun your fitness program,
stick with it until you see the results you want.
Effects of Stress
Stress is a more important factor in physical
well-being than many experts have recognized until
now. New research shows that as stress accumulates, an
individual becomes increasingly suspectable to
physical illness, behavioral and emotional problems
and accidental injury. As an example, minor muscular
twitches and nervous ticks become more noticeable when
one is under stress. A variety of other physical
symptoms may be recognized. From the digestive tract
to the major organs of the body -- all are affected
dramatically by stress. While the outward appearance
to the body may be physically fit, the inside may be
causing problems and treatment is indicated.
Target Heart Rate
Okay, it's time to get out your calculator, pen and
paper. We're going to figure out your target heart
rate. If you're ready to start an aerobic fitness
program, it's essential to know this rate because the
key to getting the most out of aerobic exercise is
reaching your target heart rate and holding it here
for about 20 to 30 minutes. Are you ready? First, you
need to establish your maximum heart rate. If you're a
man, take half of your age and subtract from 205. If
you're a woman, subtract your age from 220. For
example: if you're a 40 year old woman, your maximum
heart rate is 180. The next step is to figure out your
target heart rate. Just take 80% of your maximum heart
rate and bingo. So, if your maximum heart rate was
180, then your target heart rate is 144. Time your
heartbeat during your exercise program and when your
reach the target rate, keep exercising at that level
for about 20 to 30 minutes.
General Guidelines
Should You Consult A Doctor First?
Most people do not need to see a doctor before they
start an exercise program since a gradual, sensible
exercise program will have minimal health risks.
However, there are some people who should seek medical
advice. To find out if you should consult a doctor
before you start, use the following check list
developed by the National Heart, Lung and Blood
Institute - NHLBI. From the following list, take note
of those items that apply to you:
1. You have heart trouble, a heart murmur, or you
have had a heart attack.
2. You frequently have pains or pressure--in the
left or mid-chest area left neck, shoulder, or arm,
during or right after you exercise.
3. You experience extreme breathlessness after mild
exertion.
4. Your blood pressure is too high, and/or it is
not under control. Or you don't know whether or not
your blood pressure is normal.
5. You have bone or joint problems such as
arthritis.
6. You are over age 60 and not used to vigorous
exercise.
7. Your father, mother, brother, or sister had a
heart attack before age 50.
8. You have a medical condition not mentioned here
which might need special attention in an exercise
program. If you've noted one or more items, talk to
your doctor before you start. If you've noted none of
the items, the NHLBI suggests you can started on a
gradual, sensible exercise program tailored to your
needs.
Keys To Fitness Success
The key to a successful exercise program is
choosing an activity that you will enjoy. To determine
what type of exercise is right for you, consider the
following: How physically fit are you and what
activities will help you achieve the level of fitness
you are after? Do you like to exercise alone or with
other people and do you like to exercise indoors,
outdoors or in your home? How much money are you
willing to spend for equipment or facilities, and when
can you best fit the activity into your schedule? By
choosing activities you like, you can afford and can
fit into your schedule, you'll be more likely to
exercise regularly, keep on exercising, and enjoy its
many benefits. To help keep you going once you get
started, here are a few tips: Choose activities that
you enjoy and make exercise part of your daily
routine. Also be sure to set realistic goals. Exercise
with a group for social interaction as well as
physical fitness and keep a written record of your
progress. Exercise to music. Select loose, comfortable
clothes for your chosen activity and wear appropriate
shoes. Pay attention to your body and stop if you feel
pain. Increase your daily activities and park away
from a building and walk; take the stairs instead of
the elevator. Exercise indoors when temperatures
outside are extremely hot or cold. Find a fitness
buddy" so you can help each other stay motivated.
Choosing Exercises and
Activities
If you want to condition your heart and lungs,
you'll need to choose exercises which raise your heart
and breathing rates and are done for a duration of at
least 15 to 30 minutes without interruption. You must
also do these exercises a minimum of three times per
week. There are three different types of activities
that will give you various levels of conditioning:
very vigorous, moderately vigorous and not vigorous.
Some very vigorous activities include: cross-country
skiing, uphill hiking, ice hockey, jogging, jumping
rope, rowing, running in place and stationary cycling.
Some moderately vigorous activities include:
bicycling, downhill skiing, basketball, calisthenics,
field hockey, handball, racquetball, squash, swimming,
singles tennis and walking. Lastly, there are some
activities that are not vigorous and DO NOT condition
your heart and lungs. Some of those activities
include: baseball, bowling, football, golf, softball
and volleyball. These activities however, can be
enjoyable, help to improve coordination and muscle
tone and relieve tension.
Pace Yourself
The key is to build up slowly. No matter where you
begin, you will be able to build up your exercise time
or pace as your body becomes more fit. You can find
out how hard to exercise by keeping track of your
heart rate. Your maximum heart rate is the fastest
your heart can beat. The best activity level is 60
percent to 75 percent of this maximum rate. This 60
percent to 75 percent range is called your heart rate
Target Zone. When you begin your exercise program, aim
for the lower part of your heart rate Target Zone --
60 percent, during the first few months. As you get
into better shape, gradually build up to the higher
part of your Target Zone - 75 percent. After six
months or more of regular exercise, you can exercise
at up to 85 percent of your maximum heart rate.
However, you do not have to exercise that hard to stay
in good shape. Each exercise session should last from
about 25 minutes to 40 minutes and should include the
following: Five minutes of warm up exercises; 15
minutes to 30 minutes of exercising in your heart rate
target zone; five minutes of cool down exercises.
Heart Rate Target Zone
The goal of exercising to strengthen your hearts
and lungs is to raise the heart rate to a certain
level and keep it there for 20 minutes. Find your
target heart or pulse rate by subtracting your age
from 220, and then multiplying the result by 70
percent. For example, for a 60-year-old person, the
target rate would be (220-60) x 70 percent or 112.
Remember, go slowly. For a person who has not
exercised regularly, it may take several months to
raise the rate to 70 percent.
President's Council on Physical
Fitness and Sports Guidelines
The following guidelines, prepared by the
President's Council on Physical Fitness and Sports,
are intended for the average healthy adult. If you're
just beginning a physical fitness program, keep in
mind that success requires commitment and patience is
essential. Don't be tempted to do to much too soon
because you'll end up quitting before you've given
yourself the opportunity to feel the benefits.
Constantly remind yourself about the benefits and what
your personal fitness goals are. If you're under 35
years of age and in good health, you probably do not
need to call or see a doctor before beginning an
exercise program. But, if you're over 35 years of age
and have been inactive for several years, you should
consult your physician before starting an exercise
program. If you currently have, or have ever had, any
of the following medical conditions, you should
consult with a physician prior to beginning an
exercise program, according to the President's Council
on Physical Fitness and Sports: High blood pressure;
heart trouble; family history of stroke or heart
attacks; frequent dizzy spells; extreme breathlessness
after mild exertion; arthritis or other bone problems;
severe muscular, ligament or tendon problems; other
known or suspected diseases or medical conditions,
including back problems. Vigorous exercise involves
minimal health risks for persons in good health or
those following a doctor's advice. Far greater risks
are presented by habitual inactivity.
What Is "Physical Fitness"
Physical fitness is a condition that helps us look,
feel and do our best. More specifically, it's the
ability to perform daily tasks vigorously and alertly,
with energy left over for enjoying leisure-time
activities and meeting emergency demands. It's the
ability to endure, to bear up, to withstand stress, to
carry on in circumstances where an unfit person could
not continue, and is a major basis for good health and
well-being. Physical fitness involves the performance
of the heart and lungs, and the muscles of the body.
And, since what is done with the body can affect what
is done with the mind, fitness influences to some
degree qualities such as mental alertness and
emotional stability, according to the President's
Council on Physical Fitness and Sports Fitness is an
individual quality that varies from person to person.
It is influenced by age, sex, heredity, personal
habits, exercise and eating practices. You can't do
anything about the first three factors. However, it is
within your power to change and improve the others
where needed.
The Four Components Of Physical
Fitness
Physical fitness is most easily understood by
examining its components. According to the President's
Council on Physical Fitness and Sports, there is
widespread agreement that these four components are
the basics. Cardiorespiratory endurance or the body's
ability to deliver oxygen and nutrients to tissues,
and to remove wastes, over sustained periods of time.
Long runs and swims are among the methods used to
assess cardiorespiratory endurance. Muscular strength
is the ability of a muscle to exert force for a brief
period of time. Upper-body strength, for example, can
be measured by various weight-lifting exercises.
Muscular endurance is the ability of a muscle, or a
group of muscles, to sustain repeated contractions or
to continue applying force against a fixed object.
Pushups are often used to test endurance of arm and
shoulder muscles. And flexibility is the ability to
move joints and use muscles through their full range
of motion. The sit-and-reach test is a good measure of
flexibility of the lower back and backs of the upper
legs.
Your Workout Schedule
How often, how long and how hard you exercise, and
what kinds of exercises you do need to be determined
by what you are trying to accomplish for yourself and
not others. Your fitness goals, present fitness level,
age, health, skills, interest and convenience are
among the factors you should consider. For example, an
athlete training for high-level competition would
follow a different program than a person whose goals
are good health and the ability to meet work and
recreational needs. Here are the amounts of activity
needed for the average, healthy person to maintain a
minimum level of overall fitness. Included are some of
the popular exercises for each category. The warmup
which should be five to ten minutes of exercise such
as walking, slow jogging, knee lifts, arm circles or
trunk rotations. Low intensity movements that simulate
movements to be used in the activity can also be
included in the warmup. To build muscular strength,
you'll need a minimum of two 20-minute sessions per
week that include exercises for all the major muscle
groups. Weight training is the most effective, but not
the only, way to increase strength. Muscular endurance
can be achieved with at least three 30-minute sessions
each week that include exercises such as calisthenics,
pushups, situps, pullups, and weight training for all
the major muscle groups and cardiorespiratory
endurance can be achieved with at least three 20
minute bouts of continuous aerobic exercise each week.
Popular aerobic conditioning activities include brisk
walking, jogging, swimming, cycling, rope-jumping,
rowing, cross-country skiing, and some continuous
action games like racquetball and handball. To gain
flexibility, you'll need ten to twelve minutes of
daily stretching exercises performed slowly, without a
bouncing motion. These stretching exercises can be
included after a warmup or during a cool down. Finish
your workout with a cool down. A minimum of five to
ten minutes of slow walking, low-level exercise,
combined with stretching is a good cool down.
Weight Control vs Fat Control
The key to weight control is keeping food
consumption and physical activity in balance. When you
consume only as many calories as your body needs, your
weight will usually remain constant. If you take in
more calories than your body needs, you will put on
excess fat. If you expend more energy than you take
in, you will burn excess fat. Exercise plays an
important role in weight control by increasing energy
output, calling on stored calories for extra fuel.
Recent studies show that not only does exercise
increase metabolism during a workout, but it causes
your metabolism to stay increased for a period of time
after exercising, allowing you to burn more calories.
How much exercise is needed to make a difference in
your weight depends on the amount and type of
activity, and on how much you eat. A medium-sized
adult would have to walk more than 30 miles to burn up
3,500 calories, the equivalent of one pound of fat.
Although that may seem like a lot, you don't have to
walk the 30 miles all at once. Walking a mile a day
for 30 days will achieve the same result, providing
you don't increase your food intake to negate the
effects of walking. If you consume 100 calories a day
more than your body needs, you will gain approximately
10 pounds in a year. You could take that weight off,
or keep it off, by doing 30 minutes of moderate
exercise daily. The combination of exercise and diet
offers the most flexible and effective approach to
weight control.
Exercise Equipment
What to Look for in Exercise
Equipment
While looking at exercise equipment, keep in mind
you need equipment that is not only durable and well
designed, but that fits your physical needs and
lifestyle. By thinking ahead, you can get equipment
which will last for years and is comfortable and easy
to use. Exercise equipment varies in price. Remember,
you get what you pay for. The low end of the price
scale may not perform satisfactorily or last over
time. There probably will not be service or
replacement parts available. If you purchase quality
equipment, it will cost more, but it is usually a one
time investment. Be sure to test any equipment in the
store before purchasing it. Look for comfort, quality,
design, and noise level. Ask about warranty
information and find a knowledgeable salesperson who
can explain how the equipment works. The better
equipment with a variety of features, comfort, and
quality will keep you interested longer with less down
time and stress and strain on your body. For more
information consult an exercise equipment authority.
Types of Exercise Equipment
If you're searching for exercise equipment, the
most favored aerobic types are exercise bikes, stair
masters, treadmills, and cross country ski machines.
To tone muscles and body strength, you should look
into free weights, home gyms, and rowing machines.
There are a variety of designs within each type of
equipment. For example, treadmills can be either
motorized or manual. A motorized treadmill can be set
for speed and incline so you can walk or jog. A
treadmill utilizes a natural form of exercise with
little stress to the body and are relatively quiet. An
incline will help burn more calories and also used
different muscle groups. Bikes can be upright
stationary, dual action, fan type, or computerized
motorized body bikes. Be sure a bike is comfortable
and can be moderated to fit your needs. Stair masters
can have dependent or independent climbing and also
include programs which keep you interested. You should
be in pretty good shape to use to a stair climber. If
you are thinking of purchasing any of the types of
equipment, don't forego quality and durability based
on price alone. Home gyms are offered with a variety
of features, benefits, components, and also sizes.
Customary weight systems are preferred over rubber
bands, shocks, or other types because they feel better
and let you know exactly how much weight you are
working with. Also consider the range of motion
available, how many muscle groups will be used and how
smoothly it functions. When purchasing exercise
equipment, be sure to get the best quality with
durable construction. Better equipment will last a
lifetime with little service or down time. To find out
more about exercise equipment, contact an exercise
equipment specialist.
Special Exercise Needs
People with special needs, such as health problems,
injuries, obesity, or a heart or back problem should
consult their physician before purchasing any exercise
equipment. A physician can guide you to the equipment
which will benefit you most. For example, if you had a
knee injury, a stationary bike could help your
recovery. For a back injury, walking on a motorized
treadmill is usually recommended. Rehabilitation
centers usually incorporate the use of free weights as
well as multi-station gyms. This can enhance range of
motion, muscle tone and strength. When purchasing
equipment, the exercise equipment dealer should be
knowledgeable and enthusiastic about helping you.
Heart patients or persons charting results should
think about investing in a chest style heart monitor.
For better results, it should not be hooked up to the
equipment. Work with your special needs to get the
safest and most effective workout your body needs. For
further information, see an exercise equipment
professional.
Benefits of Using Exercise
Equipment
There are many benefits associated with owning your
own exercise equipment. Privacy and convenience are
some examples. You can use your equipment any time of
the day or night, whenever is it best for you. There's
no driving to the club, waiting for you turn on the
equipment, or concern about cleanliness. By purchasing
the equipment in lieu of a membership, you will have
something tangible for your money. You must weigh the
alternative of owning your own equipment and joining a
health club and make the right decision for yourself.
For more information, see your local exercise
equipment professional.
What to Buy
Buying exercise equipment for the home is a smart
idea for busy people who want to squeeze regular
exercise into an already hectic schedule. But, before
you purchase a piece of equipment, there are a number
of things to consider. First - what are your fitness
goals? If you're looking to improve your aerobic
fitness, you might consider a treadmill, a stair
climber, a ski machine or a stationary bike. If
muscular strength is your goal - consider purchasing a
home gym. A home gym should be easy to use and provide
proper body positioning. Whatever your goals, be sure
to choose an activity that you enjoy. Make sure you
have enough space to use the equipment properly. Also,
be aware of any past orthopedic problems that could be
aggravated by inappropriate exercises. Here are some
things to remember when purchasing home exercise
equipment: Try out the equipment yourself. Shop around
and compare prices. Look at various models and
manufacturers. Check the warranty. And be sure to find
out what assembly, service and maintenance will be
required. |
