Title: Nutrition and Exercise


1
Nutrition and Exercise
  • Eating Well and Wisely
  • Exercise to the Fullest

2
6 Basic Nutrients
  • Protein
  • Carbohydrates
  • Fats
  • Vitamins
  • Minerals
  • Water

3
Protein
  • Growth and Repair of body tissues
  • Protein has 4 calories per one gram
  • Make-up 10 of your diet
  • All proteins are made of Amino Acids (provides
    energy)
  • 11 can be made by your body (non-essential)
  • 9 others are supplied by food (essential amino
    acids)
  • Complete Protein - contains all 9 amino acids
  • meat, poultry, fish, and milk products
  • Incomplete Proteins - contains only some amino
    acids
  • legumes, grains, nuts, and seeds

4
Carbohydrates (CHOs)
  • Instant Energy
  • CHO has 4 calories per one gram
  • Main source of food energy
  • 60 of your diet
  • CHOs are divided into three classes
  • Simple- sugars such as fructose and lactose
  • Complex- starches
  • Dietary Fiber

5
Three Classes of CHOs
  • Simple
  • Naturally occur in fruits, vegetable, honey, and
    molasses
  • Sugar in your sugar bowl is a simple sugar
    (sucrose)
  • Most important sugar is glucose (major energy
    source for cells in your body)
  • CHOs must be converted to glucose before it can
    be used as energy

6
Three Classes of CHOs(continued)
  • Glucose that is not used right away is stored in
    the liver and muscles as a starch-like substance
    called Glycogen
  • When more energy is needed, the body converts the
    glycogen back to glucose
  • When the body takes in too many carbohydrates
    than it can use or store, the excess is stored as
    body fat
  • Complex CHOs
  • Starches
  • vegetables, potatoes, grains (rice, corn, wheat,
    and oats) and beans
  • breads, cereal, and pasta are also made from
    grain
  • Complex CHOs are low in fat and rich in vitamins,
    minerals, and fiber
  • The body must break down complex into simple
    before it can use them for energy

7
Three Classes of CHOs(continued)
  • Dietary Fiber
  • Complex CHO that does not provide energy
  • Provides bulk in large intestine
  • Helps to move undigested food through the
    digestive tract, prevents constipation and
    reduces the risk of colon cancer
  • Whole grain wheat bran, corn, rice, corn bran,
    and rice bran
  • Fruits and vegetables are good sources of fiber
  • It is recommended that you consume between 20 and
    35 grams of dietary fiber a day

8
Fats
  • Long term energy
  • 9 calories per gram of fat / 30 of your diet
  • Fat compounds are also called Lipids
  • A fatty substance that does not dissolve in water
  • many hormones, including sex hormones are made
    for lipids
  • Transportation for fat soluble vitamins
  • Fat takes a longer time to digest

9
Fats (continued)
  • Saturated-Animal fats (LDL- bad)
  • no more than 10 of your diet
  • saturated fats are often solid at room
    temperature
  • butter and lard
  • palm oil and coconut oil
  • saturated fat has been linked to heart disease,
    cardiovascular disease, and some forms of cancer
  • Unsaturated - Plant source (HDL- good)
  • vegetable oils and fish oils

10
Fats (continued)
  • Unsaturated fats - Plant source (HDL) mainly
    vegetable oils and fish oils
  • 2 types Mono- polyunsaturated
  • Monounsaturated - These include safflower, sesame
    and sunflower seeds, corn and soybeans, many nuts
    and seeds, and their oils.
  • Polyunsaturated - These include canola, olive and
    peanut oils, and avocados.
  • Both polyunsaturated and monounsaturated fats
    may help lower your blood cholesterol level when
    you use them in place of saturated fats in your
    diet. But a moderate intake of all types of fat
    is best

11
Cholesterol
  • Cholesterol is a fat-like substance found in some
    foods of animal origin
  • Cholesterol is also produced by the liver
  • Production of Vitamin D
  • Production of certain sex hormones
  • Body makes all the cholesterol it needs
  • HDL Cholesterol
  • good cholesterol (protects against heart disease)
  • LDL Cholesterol
  • bad cholesterol causes plaque build-up, clogs
    arteries, restrict the supply of oxygenated blood
    to the heart which can result in a heart attack

12
Vitamins
  • Help regulate certain chemical reactions in the
    body
  • Vitamins D and K are the only vitamins that the
    body can make
  • Vitamins do not supply energy
  • Fat Soluble Vitamins
  • Absorbed, stored, and transported in fat
  • A,D,E,and K
  • Excess is stored in the liver or skin, and may be
    toxic
  • Water Soluble Vitamins
  • Dissolve in water and pass easily into the blood
    during digestion
  • Body doesnt store them so they need to be
    replenished
  • B and C
  • Excess is excreted in urine

13
Vitamins - Fat Soluble (continued)
  • Vitamin A
  • Maintains healthy eyes, skin, teeth, bones
  • Deficiency - night blindness, impaired growth
  • Vitamin D
  • Helps build bones and teeth
  • Deficiency - Rickets (inadequate growth of bones
    teeth)
  • Vitamin E
  • Prevents destruction of red blood cells
  • Deficiency - red blood cell rupture causing
    anemia
  • Vitamin K
  • Assists with blood clotting, bone growth
  • Deficiency - slow clotting of blood, hemorrhage

14
Vitamins - Water Soluble(continued)
  • Vitamin C
  • Needed for normal development of connective
    tissue
  • Helps absorb the mineral iron
  • Wound healing
  • Deficiency - Scurvy (slow healing of wounds,
    bleeding gums)
  • Vitamin B (B1,B2,B3,B6,B12,)
  • Assists with conversion of carbohydrates
  • Assists with nerve cell function
  • Maintenance of normal metabolism
  • Necessary for formation of red blood cells
  • Deficiencies
  • Cheilosis (skin sores on nose and lips)
  • Pellagra (soreness on mouth, diarrhea,
    irritability, depression)
  • Anemia

15
Minerals
  • Minerals are divided into two categories
  • Macrominerals- needed in large amounts in the
    body
  • Microminerals or trace minerals
  • Macrominerals
  • calcium, chlorine, magnesium, phosphorus,
    potassium sodium, sulfur
  • Micromineral
  • and trace minerals include chromium, fluorine,
    copper,
  • iodine, iron, manganese, zinc

16
Minerals (continued)
  • Sodium and Chlorine are two minerals that
    regulate fluid balance
  • Dissolved salts are called electrolytes
  • Ordinary table salt is a major source of sodium
  • Too much sodium has been linked to high blood
    pressure, fluid around the heart, kidney
    problems, and irregular heart beat
  • Daily sodium intake should be less than 3,000 mg.
  • Calcium and Magnesium
  • Bone growth and development
  • Muscular contractions and relaxation
  • Iron
  • Helps prevent fatigue
  • Helps build red blood cells

17
Minerals (continued)
  • Potassium
  • Helps maintain normal metabolism
  • nerve and muscle function
  • Zinc
  • Needed for digestive enzymes
  • healing of wounds
  • plays a role in respiration
  • Chromium
  • necessary for proper blood sugar regulation
  • proper insulin activity

18
Water
  • You need _at_ least 2 quarts or 64 ounces a day.
  • Makes up two-thirds of your body
  • Keeps levels of other nutrients in balance
  • Regulates body temperature
  • Transports water soluble vitamins
  • Allows for the passage of gases,nutrients, and
    wastes
  • check the color of urine to find out it you are
    drinking enough water (dark urine means you need
    to increase your water intake)
  • A state of dehydration may occur if you lose more
    water than you take in.
  • dehydration may occur as a result of heavy
    physical activity, vomiting, diarrhea, or fever

19
Calories
  • Calories is defined as the amount of energy you
    obtain from food
  • One pound 3,500 calories
  • Eating 500 fewer calories per day will result in
    the loss of 1 pound of body fat per week
  • Males 2,000-2,800
  • Females 1,800-2,400

20
Food Intolerance
  • A negative reaction to a food or part of food
    caused by a metabolic problem
  • Milk, wheat, additives
  • Some are hereditary- inability to digest lactose
    (milk sugar)

21
Hunger vs Appetite
  • Hunger- the bodys physical response to the need
    for food
  • A feeling you are born with
  • Symptoms weakness, hunger pains, dizziness,
    nausea, loss of concentration
  • Appetite- the desire to eat based on the pleasure
    derived from eating
  • Factors taste, texture, or aroma of the food
  • Satiety- feeling of fullness

22
Dietary Guidelines for Americans
  • Eat a variety of foods
  • Maintain a healthy weight
  • Choose a diet low in fat, saturated fat, and
    cholesterol.
  • Eat plenty of fruits, vegetables, and grain
    products.
  • Use sugar in moderation
  • Use salt and other forms of sodium in moderation
  • Drink alcohol in moderation
  • 90 percent of people who diet gain it back within
    1 year

23

32
Why diets dont work
  • Reduce your Basal Metabolic Rate
  • Many people cannot go long term on the
    restrictive eating plan
  • They are like people who try to stop smoking
    crabby and irritable
  • Lower self-esteem

33
Basal Metabolic Rate (BMR)
  • Amount of energy it takes to keep your body
    functioning normal when at rest
  • Differs with age, sex, and body type
  • On average, you burn about 1000 calories at rest.

    range for his/her height
  • Obesity
  • Having an excess amount of body fat
  • Athletes may be overweight because of excess
    muscle rather than fat
  • Underweight
  • A person is less than the standard weight range
    for his/her height

37

Bulimia
  • Bulimia
  • Binge and Purge eating disorder.
  • Binge Rapid consumption of large quantities of
    food.
  • Purge Self-induced vomiting and/or overuse of
    laxatives.
  • Usually begins in early or middle adolescence.
  • Studies show that it can be from a chemical
    malfunction in the brain and possibly from birth
  • Affects predominantly young females.
  • Statistics range from 4.5 to 18 are affected by
    bulimia.
  • Bulimia is more common among women than anorexia
    nervosa.

42
Bulimia
  • Bulimia Symptoms
  • Depression after a binge-purge episode.
  • Physical Effects
  • Fatigue/Weakness
  • Constipation/Bloating
  • Swollen salivary glands
  • Erosion of tooth enamel.
  • Sore throat (from stomach acids by repeated
    vomiting).
  • Dehydration
  • Loss of potassium.
  • Tearing of the esophagus (caused by vomiting).
  • Overuse of laxatives cause dangerous loss of
    fluid/minerals.

43
Anorexia Nervosa/Bulimia
  • Treatment Options
  • Success rate is good if it is detected early on
    in life.
  • Hospitalization may be recommended if body weight
    drops below 30 below the ideal weight.
  • Cognitive Therapy
  • convince people that their view of being
    overweight is incorrect.
  • Behavioral Therapy
  • Develop a contract for the patient to gain weight
    in exchange for certain rewards.
  • Family Therapy Help families to understand the
    illness.

44
Binge Eating
  • Most people with binge eating disorder are
    overweight
  • Common Symptoms
  • Eating large amounts of food, even when not
    physically hungry
  • Eating until uncomfortably full
  • Eating alone out of embarrassment at the quantity
    of food being eaten
  • Feelings of disgust, depression, or guilt after
    eating
  • Complications
  • Diabetes
  • High blood pressure
  • High cholesterol
  • Heart disease

45
Aerobic vs Anaerobic
  • Aerobic uses oxygen
  • Uses big muscles, maintained continuously for
    long periods of time (10 min 3xs or 20-30 min
    1x)
  • walking, running, rowing, cross country skiing,
    aerobic classes
  • Anaerobic does not use oxygen
  • Short term, concentrated muscle group
  • Weight training, football, wrestling, golf

46
Exercise
  • Find one you enjoy
  • Warm up
  • Stretch
  • Workout
  • Cool down
  • Stretch
  • Stretching prevents injury and soreness

47
Elements of Fitness
  • Cardiorespiratory Endurance - the ability of the
    heart, lungs, and blood vessels to utilize and
    send fuel and oxygen to the bodys tissues during
    long periods of moderate-vigorous activity
  • Muscular Strength the amount of force a muscle
    can exert
  • Muscular Endurance the ability of the muscles
    to perform physical tasks over a period of time
    without being fatigued
  • Flexibility the ability to move a body part
    through a full range of motion
  • Body Composition the ratio of body fat to lean
    body tissue, including muscle, bone, water, and
    connective tissue such as ligaments, cartilage,
    and tendons

48
Principles of a WorkoutF.I.T.T.
  • Frequency- how often you do the activity each
    week
  • Intensity- how hard you work at the activity per
    session
  • Time/duration- how much time you devote to a
    session
  • Type- which activities you select

49
Types of Resistance Exercise
  • Isometric
  • Uses muscle tension to improve muscular strength
    with little or no movement of the body part
  • Push against wall or an immovable object
  • Isotonic
  • Combines muscle contraction and repeated movement
  • Push-ups, pull-ups, sit-ups, using dumbbells
  • Isokinetic
  • Resistance is moved through an entire range of
    motion at a controlled rate of speed
  • Stationary bike, treadmill, cable machines

50
Target Heart Rate
  • Maximum Target Heart Rate - exercising above this
    rate can result in injury
  • Target Heart Range keep your target heart
    within this range to safely build
    cardiorespiratory endurance- 70-85
  • Minimum Target Heart Rate exercising below this
    rate will not build cardiorespiratory endurance
  • Take pulse for 6 seconds and multiply by 10
  • 220 age maximum heart rate
  • Subtract your resting heart rate from maximum
    heart rate
  • Multiply the number you arrived at in step 3 by
    70 and again by 85, round to nearest whole
    number
  • Add your resting heart rate to the s you
    arrived at in step 4
  • The results are your target heart range

51
Benefits of Exercise
  • Burns fat and calories
  • Increases BMR
  • Sleep Better
  • Lowers Cholesterol
  • Raises Self-Esteem
  • Reduces Depression
  • Slower heart rate

52
Benefits of Exercise - Continued
  • Lowers heart disease risk
  • Lowers risk of certain cancers
  • Metabolize sugars better
  • Increase Oxygen flow

53
Training at Peak Performance
  • Nutrition/ Hydration
  • Adequate Rest
  • Avoid Harmful Substances
  • Tobacco, alcohol, steroid,
  • some supplements

54
Safety
  • Health Screening
  • Personal Safety
  • Using Proper Equipment

55
Physical Activity Injuries
  • Weather Related
  • Heat Related
  • Over exertion- overworking the body
  • Heat cramps- muscle spasms that result from loss
    of large amounts of salt and water
  • Heat stroke- body loses ability to rid itself of
    excessive heat through perspiration
  • Cold Related
  • Frostbite- body tissues become frozen
  • Hypothermia- body temp. dangerously low

56
Minor Injuries
  • Muscle cramp
  • Spasm or sudden tightening of a muscle
  • Strain
  • Damage to a muscle or tendon
  • Sprain
  • Injury to ligament surrounding a joint

57
Major Injuries
  • Rest
  • Ice
  • Compression
  • Elevation
  • Fracture/Dislocation, Tendonitis, Concussion
