• 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.
• 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 our bodys movement.

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)

6
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 its 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
• 9 Amino Acids cant be made by the body and must
  come from food you eat Essential Amino
  AcidsHistidine, Isoleucine, Leucine, Lysine,
  Methionine, Phenylalanine, Threonine, Tryptophan,
  Valine
• Protein must be cooked or breaks down in the
• stomach from stomach acid

9
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

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

Protein Sources

• 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

• Protein 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
