					1. The key biomechanical principles we learned in
badminton are force, levers and rotary motion which
makes our body move..
We can apply these principles in swimming by using
our arms & legs for levers and force and our
shoulders for rotary motion.

2.The density of the water, air in our lungs and
our body composition all affect our buoyancy which
helps us float. If we have high body fat our buoyancy
increases

3. Drag is an external force that opposes movement
either forward or backward. Friction is a form of drag.
Drag is a biomechanical principle because it affects
                                               1
our body’s movement.

                      Protein
              Fat in our Diet


•   Stored energy
•   Adds tenderness and flavors food
•   Makes us feel full
•   Transports fat-soluble vitamins
     A, D,E & K
•   Other functions of fat ?
                         Fats

• Saturated – Solid at room
temperature, comes from
animals, burns at a higher
temperature, LDL
(Trans-Fat, Hydrogenated Oil)
• Unsaturated – Liquid at
room temperature, come
from plants, burns
at a lower temp. HDL
(Monounsaturated,
Polyunsturated)
      Hydrogenated or Partially
          Hydrogenated Oil
• In processed foods. Keeps food fresher
  longer
• Makes an unsaturated fat act like a
  saturated fat
• Hydrogen is forced into the liquid oil
• Has a high burning point so it’s good for
  for frying
• Easy to handle, easy to spread and easy
  to store

           Protein-The Building Blocks
• Body breaks down protein into Amino Acids
• 20 Amino Acids. Your body can make 11
   Ø9 Amino Acids can’t be made by the body and
    must come from food you eat “Essential Amino
    Acids”Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine
   ØProtein must be cooked or breaks down in the
                           stomach from stomach acid
Essential Amino Acids must be supplied by
your diet. They are not made by your body
 Function of Essential Amino Acids
• Contributes Fatty Acids to brain and
  nerves
• Promotes normal growth and vision
• Assists in gene regulation
• Maintains outer structure of the skins,
• Helps regulates genetic activities affecting
  metabolism
• Support immune cell function           9
          Essential Amino Acids -
    must be supplied by your diet
• *Omega 6* found in vegetables oil (corn,
  cottonseed, safflower, sesame, soybean,
  and sunflower)
• Omega 3 found in certain fish (Mackerel,
  salmon, anchovy, herring, lake trout,
  sardines, tuna) and from some oils
  (walnuts, soybeans, cranola) and seeds
  and nuts (butternuts, flaxseeds, walnuts,
  soybeans)
  * most common in diet                 10
Protein Sources


                  Beans
                  Fish
                  Chicken
                  Red Meat
                  Eggs
                  Nuts
                  Grains
–   *Complete essential Amino
    Acids come from animal protein
    and are the easiest to digest
        *preferred by body

* Incomplete Essential Amino Acid
come from nuts, beans,
and rice
         Energy and Protein
vProtein is used for energy only
 when there is no glucose or fat left
 to keep the body alive!

            Protein Functions

•   Supports Growth and Maintenance
•   Builds Enzymes and Hormones
•   Maintains Electrolyte and Fluid Balance
•   Maintains Acid-Base Balance
•   Blood Clotting
•   Builds Antibodies
•   Provides Energy
