1. 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 body’s movement.

3. Percentage of Calories Recommended
30% Fat
55-60%
Carbohydrates
12-15%
Protein

4. 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 ?

5. 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 it’s good for for frying
Easy to handle, easy to spread and easy to store

8. Protein-The Building Blocks
Body breaks down protein into Amino Acids
20 Amino Acids. Your body can make 11
9 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
Protein must be cooked or breaks down in the
stomach from stomach acid

9. Essential Amino Acids must be supplied by your diet
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

10. 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

11. Protein Sources
Beans
Fish
Chicken
Red Meat
Eggs
Nuts
Grains

12. * Incomplete Essential Amino Acid come from nuts, beans, and rice
*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

13. Energy and Protein Protein is used for energy only
when there is no glucose or fat left
to keep the body alive!

14. 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
