  1. Evaporation- only cool never heat

    Convection-air
    moving across you (fan/breeze)

    Conduction-coming
    in contact with something warmer or colder than you

    Radiation-process
    by which heat radiates outward. (From sun, stove )
  2. Body Mass Index- wt in lbs * 703/ ht in inches squared
  3. Gradation of contraction is a
    function o-number of fiber recruited and
    how often you recruit them
  4. dehydration-
    have to replace fluid and electrolytes

    Eating disorders-athletes
    and women are both a problem

    Menstrual Dysfunction or abnormal menstruation – low body, wt low fat, vegetarian can
    effect menstrual cycle

    The body stores excess carbohydrate- stores in both muscle and liver
  5. Glycemic Index related
    to glucose and glycogen. Foods that trigger the high rise in blood sugar
    rapidly. Mostly sugars and starches. ( I missed this in lecture, will cover
    Wednesday)
  6. Caffeine increase
    fat use to increase endurance performance. Increase metabolism (fat burner),
    delay fatigue so you can work harder and longer.

    Creatine- loads
    the PC system to increase power, decrease fatigue, increase muscle size and wt.
    Muscle strains and cramps can occur.
  7. Amphetamines- increase
    metabolism and energy output and decrease fatigue, decrease appetite, increase
    aggression.

    Anabolic steroids- Promote
    muscle growth and is effective. Can cause roid rage, liver problems

    Amino acids- Amino Acids are the chemical units or "building blocks" of the body that
    make up proteins.

    Human growth hormone- promotes fat burning. enhances tissue growth by stimulating protein
    formation

    Significantly improves long endurance

    Blood doping-remove
    and later reinfuse red blood cells to increase bolld o2 capability. Aids
    endurance.
  8. As we age – max
    heart rate declines, mature adults are more sensitive to heat and don’t
    tolerate cold as well
  9. Epimysium-the
    outermost fibrous sheath that covers a muscle, continuous with the perimysium

    Perimysium-a sheath of connective tissue that
    groups muscle fibers into
    bundles (anywhere between 10 to 100 or more) or fascicles.

    Myofibrils- a
    basic unit of a muscle. composed of long proteins such as actin, myosin, and titin, and other proteins that hold them
    together
  10. Glucose-a simple sugar (monosaccharide) and an
    important carbohydrate in biology. Cells use it as the primary source of energy[1] and a
    metabolic intermediate
  11. Type I (Black, Red, Dark) –SLOW TWITCH. iron endurance

    Type II (white)- FAST TWITCH power,speed, no aerobic
    capacity ANAEROBIC

    Type IIX (Gray, Intermittent)-
    can go either way…..aerobic or anaerobic
  12. Atrophy-Pathology A wasting or decrease in size
    of a body organ, tissue, or part owing to disease, injury, or lack of use

    Hypertrophy-The enlargement of an organ or
    tissue from the increase in size of its cells.Autogenic

    Synchronized

    Hyperplasia- abnormal increase in
    the number of normal cells in normal arrangement in an organ or tissue, which
    increases its volume
