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 andour body composition all affect our buoyancy which helps us float. If we have high body fat our buoyancy increases3. 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% Fat55-60%Carbohydrates12-15%Protein
4 Fat in our Diet Stored energy Adds tenderness and flavors food Makes us feel fullTransports fat-soluble vitaminsA, D,E & KOther functions of fat ?
5 Fats Saturated – Solid at room temperature, comes from animals, burns at a highertemperature, LDL(Trans-Fat, Hydrogenated Oil)Unsaturated – Liquid atroom temperature, comefrom plants, burnsat a lower temp. HDL(Monounsaturated,Polyunsturated)
6 Hydrogenated or Partially Hydrogenated Oil In processed foods. Keeps food fresher longerMakes an unsaturated fat act like a saturated fatHydrogen is forced into the liquid oilHas a high burning point so it’s good for for fryingEasy to handle, easy to spread and easy to store
8 Protein-The Building Blocks Body breaks down protein into Amino Acids20 Amino Acids. Your body can make 119 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, ValineProtein must be cooked or breaks down in thestomach 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 AcidsContributes Fatty Acids to brain and nervesPromotes normal growth and visionAssists in gene regulationMaintains outer structure of the skins,Helps regulates genetic activities affecting metabolismSupport immune cell function9
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 diet10
11 Protein SourcesBeansFishChickenRed MeatEggsNutsGrains
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 Acidcome from nuts, beans,and rice
13 Energy and Protein Protein is used for energy only when there is no glucose or fat leftto keep the body alive!
