Should you pay more….
If you weigh more? That’s what Alabama’s State Employees’
Insurance Board thinks. In 2011 the board will start charging overweight state workers—those with a body mass index greater than 35—$25 a month for health insurance, which is currently free for all state employees.
Being the second fattest state in the US costs up to $1.32 billion a year in estimated medical charges, according to a 2004 study.

What is Physical Fitness?
What is Exercise? A physical activity that is performed for the purpose of either
improving, maintaining, or expressing a particular type(s) of physical fitness.
eg: training for or performing athletics, sports, or recreational activities such as jogging, roller blading, ice skating, swimming,
etc.What is Physical fitness? Ability of body to adapt to demands of physical effort-that is to
maintain mod. to vig. Levels of physical activity w/o becoming overly tired.
eg: activities of daily living such as shopping, gardening, house keeping, child rearing, work-related activities, etc

What About Social Benefits?
Benefits Cont. Cardiac output -volume of blood being pumped by the
heart, in particular a ventricle in a minute (SV.) RHR-# of contractions (heart beats) of the heart in 1
min and expressed as "beats per minute" (bpm). Blood Pressure -the pressure exerted by the blood at
right angles to the walls of the blood vessels. Osteoporosis-a disease of bone in which the bone
mineral density (BMD) is reduced, bone microarchitecture is disrupted, and the amount and variety of non-collagenous proteins in bone is altered. Osteoporotic bones are more susceptible to fracture.
Osteoarthritis-characterized by the breakdown of joint cartilage and may affect any joint in your body, including those in your fingers, hips, knees, lower back Endorphins-are endogenous opioid biochemical pain relieving compounds.
The Heart
The heart of a normal individual beats re-flexively about 40 million times a year. During this time, over 4000 gallons, or 10 tons, of blood are circulated each day, and every night the heart's workload is equivalent to a person carrying a thirty-pound pack to the top of the 100 -story Empire State Building.
Resting heart rate averages 60 to 80 beats per minute. In middle-aged, unconditioned, sedentary individuals the
resting rate can exceed 100 beats per minute. In highly conditioned endurance-trained athletes, such
as Olympic cross-country skiers, resting rates in the range of 28 to 40 beats per minute have been reported.
Basic Exercise Prescriptions
Common Goals-What’s YoursWeight Loss“In-shape”TonedRipped“Buff”BenchmarksEvents
Basics of a Physical Activity ProgramWarm-Up A warm-up may help prevent injuries and
maximize performance. The warm-up increases the body's internal
temperature and the heart rate. The chance of getting injuries decreases when the heart, muscles, ligaments, and tendons are properly prepared for exertion. A warm-up should include some running-
in-place or slow jogging, stretching, and calisthenics. It should last five to seven minutes
Cool-Down One should cool down properly
after each exercise period, regardless of the type of workout.
Serves to gradually slow the heart rate and helps prevent pooling of the blood in the legs and feet.
One should walk and stretch until their heart rates return to less than 100 BPM and heavy sweating stops.
This usually happens five to seven minutes after the conditioning session.
Overload In order to produce a
training effect, the human body must be stressed into a state of overload.
By exercising at a level above normal, a variety of adaptations take place that cause the body to function more efficiently.NOT TOO MUCH!-10%
Progression
The intensity and duration of the workouts must increase in a logical and gradual manner.
Once the body has become accustomed to a certain weight or intensity level, it is time to increase the demand to stress the muscles again.
Specificity The physiological effects resulting from
overload training are specific to the type of overload.
This specificity is related to: Muscular strength The energy system The specific muscles involved.
By isolating these areas when training, you can specifically work them without the training effect carrying over to other areas. (Spot Reduction Myth)
Reversibility
The “Use it or Lose it” principle.
If you don’t use your muscles they will atrophy (shrink!)

CARDIORESPIRATORY ENDURANCE -ABILITY TO PERFORM PROLONGED, LARGE MUSCLE, DYNAMIC EXERCISE AT MODERATE TO HIGH INTENSITY.
To get cardiovascular benefits from training: Target Heart Rate 60%-80% of maximum heart rate MAX HR: 220-(AGE) Formulas: MHR x .60 = THR
Which is Better: Longer Duration and Lower Intensity or Shorter Duration with Higher Intensity?
Three Energy Systems
Aerobic vs. Anaerobic
Oxygen Debt…. “The Talk Test”Aerobic: amount of oxygen intake exceeds
the amount of oxygen used
Anaerobic: amount of oxygen used exceeds the amount of oxygen intake
Monitoring Your Heart Rate
Carotid artery in the neck Radial artery in the wrist
Count beats for 10 seconds and multiply the result by 6 to get rate in beats per minute
Karvonen Formula The Karvonen formula is considered
more accurate than the Maximal heart-rate formula, because the resting heart-rate is used in the calculation
THR = % intensity X heart-rate reserve + resting heart-rate
What is heart-rate reserve? (age predicted MHR)-(resting heart-rate)
THR - Example Here's how it would be calculated for a 14 year old with a
resting heart-rate of 80 and an age-predicted maximal heart-rate of 175 at an 80% intensity level of maximum heart-rate reserve:
205 (age predicted MHR)- 60 (resting heart-rate)145 (heart rate reserve)X.70 (intensity level)101.5
+60.00 (resting heart-rate)161.5 (target heart rate)
What is your THR using both: Maximal heart-rate formula Karvonen Formula
The TRAINING EFFECT Changes that take place in the body as
a result of increased cardiorespiratory endurance. Lower resting heart rate Increased cardiac output Increased metabolism Increased maximal oxygen consumption Increased weight maintenance
Muscular Strength and Endurance
Develop muscle by overloading High sets-low reps
Strength - few reps and heavy load “LIFT MORE” Maximal Effort
Endurance - many reps and lighter load
“LIFT LONGER” Sustained Contraction
Muscles and Exercise
Isometric – push or pull against an
immovable object, creating intervals of
fixed muscle contractions
Isotonic – muscle moves a moderate load several times
Isokinetic - machine provides resistance
through entire range of motion
FlexibilityAbility to go through the
full range of motion in a comfortable, fluid fashion.
Point of mild discomfortStretching elongates
the muscles and makes them more flexible.

Obesity DefinedObesity means that you have an unhealthy amount of body fat. Everyone needs some body fat, but too
much fat increases your risk of developing lifestyle diseases.
Defined by BMI Body Mass Index BMI is a way of estimating total body fat
for most people.
Should you pay more….
If you weigh more? That’s what Alabama’s State Employees’
Insurance Board thinks. In 2011 the board will start charging overweight state workers—those with a body mass index greater than 35—$25 a month for health insurance, which is currently free for all state employees.

BMI For Teens? Write down your weight
in pounds. Divide your weight by
your height in inches. Divide the answer from
step 2 by your height in
inches. Then multiply the answer
from step 3 by 703. The resulting answer is
your BMI.
Public schools send home weight reports
Starting this year, public schools across Massachusetts will send reports home to parents alerting them if their child weighs too much or too little.
Students in the 1, 4, 7, 10 measured and weighed so school health officials can calculate BMI.

The Simplest Answer is the Best Solution!
ENERGY EQUATION(ENERGY BALANCE)
ENERGY IN = ENERGY OUT = NO CHANGE
ENERGY IN > ENERGY OUT = GAIN WEIGHT
ENERGY IN < ENERGY OUT = LOSE WEIGHT
Units of Energy refer to Calories
There is no Magic Pill
Supplements… 1) "If it sounds too good to be true, it probably is not true.“
there is no standard for the acceptability of the supporting science. Therefore, claims may be based on single studies having inadequate
or flawed science. Among dietary supplements, less is known about herbals and
botanicals than about vitamins and minerals. There are no federal standards for herbals and botanicals to ensure their safety, purity or quality.
Natural" is not synonymous with "safe." Multivitamins in moderation may help some people.
High doses of some supplements can be harmful (more is not better). vitamin A, niacin, vitamin B6, vitamin D, iron and
folic acid. 4)
For good health, eat a variety of foods. While supplements may help in some cases, they are not the total answer.

Aging and Health
A combination of regular exercise and good
nutrition is the best way to maintain a healthy
lifestyle.
Energy Equation & Weight MaintenanceTips for Healthy Weight Loss
Exercise increases the amount of energy the body expends, helping to manage both body weight and composition.
Longer duration and more intense exercise burns more calories.
Balance with a reasonable diet (M, V & B)
Exercise is essential for weight management because it is a major part of the energy equation.

When weight maintenance moves to irrational and compulsive behaviors…..
Behaviors Discussed:Eating DisordersFemale Athlete TriadCompulsive Exercising
General Background
Psychological in nature but problems cause Physical Effects.
Best characterized as ‘Addictions’
It’s not just about disordered eating…it’s about relationships w/ others and oneself…
At a certain point, an eating disorder ceases to be "about" any one thing. It stops being about your family or your culture. Very simply, it becomes an addiction . . . -Wasted, Marya Hornbacher (p. 64)
Basic Stats~3% of women during lifetime.Estimated 5 millionGirls more than guys (~9/10). High risk of other mental and
physical illnesses that can lead to death.
Since 87’, hospitalizations increased: 34% among women under 15 29% among 15-24 year olds.
Eating Disorders Defined anorexia nervosa
refuse to maintain a minimally
normal body weight intense fear of gaining weight
(Starvation, <1600 cal/day) distorted perception of the shape or size of their bodies.
bulimia nervosa binge eating followed compensatory methods (2 X W,
>3 M) Excessive importance on body shape and weight.
binge eating disorder (BED) binge eating not followed by compensatory behavior
Methods of Abuse
Diuretics LaxativesSelf-induced vomitingDiet pillsSerious over exercising
Eating Continuum
“It's disgusting but [my eating disorder] was my safeguard, my sure thing, my life for all those years . . . It was something I knew for sure, no question, I was good at.” -Wasted, Marya Hornbacher (p. 121)
Dizziness; fainting Involuntary vomiting; vomiting blood Dehydration and low electrolytes Ulcers; bleeding throat Slower emptying of food from the stomach Chronic bloating Constipation; bloody stools Chronic diarrhea Anemia; reduced energy Facial hair Hair loss; skin sores Joint pain; cold extremities Gum disease; tooth decay Bone loss Modified sense of taste; changes in appetite Pneumonia; immune deficiency Infertility; absence of menses Liver, kidney and pancreas failure High cholesterol levels (do not signify a cholesterol problem and do not warrant a low-cholesterol diet) Enlarged heart; irregular heartbeat; cardiac compromise Sudden death
These evil thoughts, from where are they
born? -Verde's Macbeth-
SPAIN just enforced ruling that ordered every runway model on show must have a body mass index (BMI) of at least 18.
Models who are 5 ft 9 in tall must weigh a minimum of 125lbs.
Esther Cañadas (right), Spain’s best-known model, does not qualify under the new rules as she is said to have a BMI of only 14.
“In one national survey of over 6,700 adolescents in grades 5-12, half of girls and 1/5 of boys reported dieting to lose weight.”
She was afraid to eat. She lost 25% of her body weight.
She strove for perfection. Her desires and passions disappeared.
She had angry outbursts. She stopped having her periods.
She felt isolated. She was always cold.
She desired control. She felt weak.
She denied her hunger. Fine hairs grew on her entire body.
She was depressed. She suffered from insomnia.
She had a distorted body image. Her heartbeat was irregular.
She craved attention. She almost died.
Where does dedication
cross over to obsession?
Compulsive Exercise "purging?”
Repeatedly exercising beyond what is considered safe.
Tremendous guilt when they cannot exercise (almost never do it for fun)
Sense of temporary power, control and/or self-respect
Body Types

What Can We Do to Prevent?Personal
attitudes, mindsets, perceptions
Peer interactions- compliments and comments
How to help a friend
Personal Attitudes & Perceptions Don’t have to be dangerously thin to be attractive. You
can be your worst critic. Pictures in magazines are altered- don’t represent reality Accept body type Appreciate body for capabilities Body need to last a lifetime! Surround yourself with people who like you for your
personality, not physical appearance. Find self-worth in areas like academic, athletic,
personality, friendship, hobbies Focus on how body feels, not how it looks. Exercise to be fit and feel good, not to obsession.
How to Help a Friend Tell them you like them for who they are. Listen actively. Tell them you’re concerned about what you’ve seen
and heard. Be specific & nonjudgmental. Do NOT monitor food intake. May cause further
isolation and control. Tell trusted adult if concerned about safety. Ultimately person has to realize they need & want help
before treatment will be successful. Be patient with friend and try not to let her completely
isolate herself. Provide information about treatment resources and
offer to go with them and wait during therapy.

Steroids
The Least You Need to Know:What are Anabolic Steroids?Why and How Steroids are Used?The Difference Between Medical and
Anabolic Steroids?How Body Dysmorphia Applies to Men
and WomenHealth consequences: Female/Male
Anabolic Steroids Defined Anabolic Steroids are
the synthetic derivatives of the naturally occurring male anabolic hormones testosterone.
The hormone’s anabolic effect helps the body retain dietary protein, which aids in the development of muscles.
They're also known as roids, juice, hype, or pump
Types of Steroids Steroids are natural substances with many different effects in the body, In health care used to reduce inflam- mation and other disease symptoms.
Steroid inhalers have an important role in reducing deaths from asthma
Local steroid injections are useful in treating painful joints and ligaments.
Steroid creams are used extensively to treat eczema and other inflammatory skin conditions.
However steroid use in medicine is limited by very serious side effects in the body as a whole. That is why steroids tend to be used sparingly in local preparations such as sprays and creams, which ensure maximum steroid dose where it is needed, and minimum levels in the blood stream.
Steroid Administration Oral – tablets or pills Injectable – directly into the
muscle, usually buttocks Water-based – enter blood
sooner, leave sooner Oil-based – enter slower,
remain longer Oral form more dangerous
(liver dysfunction) Stacking – 2 or more steroids
simultaneously
Abusers have been known to take doses 10 to 100 times higher than the amount prescribed for medical reasons
by a doctor.
? Why Steroids are Used?Accelerated recovery Increased endurance Increased muscle
size Increased muscle
development Increased strength
Bhasin et al. (1996) – 1 lb of lean muscle gain per week by testosterone treatment group over 10 week period. (600 mg of
enanthate weekly). No increase in body fat
Why Steroids ContinuedBody Dysmorphia
Myth of Steroids
Steroids can make an average athlete
into one of the best.
Side Effects
Males Testicular atrophy Reduced sperm

from higher estradiol concentration)
Increased prostate size Baldness
FEMINIZATION
Side Effects
Females Voice deepening Reduced breast size Growth of facial and body hair Acne Altered menstrual function
MASCULINIZATION
Side Effects of Steroid Use
Both Sexes Steroids' Disfiguring Effects
Acne, greasy hair, and baldness Premature closure of growth plate in youths Lowered HDL cholesterol Higher LDL cholesterol Lower HDL/LDL ratio creates higher
risk of coronary artery disease Blood-filled cysts (peliosis hepatis) Liver dysfunction Connective tissue damage Addiction HIV, Hepatitis
Roid Rage Steroids act on the
limbic system Research shows that high
doses of steroids can cause extreme fluctuations in emotions, from euphoria to rage.
Eventually, steroids can cause mania, delusions, and violent aggression or "roid rage."

Very Few Teens Use SteroidsMost teens are smart and stay away from steroids. As part of a NIDA-funded study,
teens were asked if they ever tried steroids—even once. Only 2.5% of 8th
graders ever tried steroids; only 3.5% of 10th graders; and 4% of 12th graders.
