- 1what are the components of diet1. carbohydrates
2.proteins
3.vitamins
4. minerals
5.fibre
6.waters - 2What are the 2 types of carbohydratesSimple: easily digested by the body
e.g fruits, veg
Complex: longer for body to digest e.g bread, pasta - 3What can too much fat lead to-high cholesterol levels
-it is carried by the blood by low-density lipoprotein (ldl) and high-density lipoprotein (hdl)
-LDL can lead to fatty deposits
-HDL takes cholesterol away and takes to liver to dispose of - 4what are proteins important for-muscle growth and repair
- they are mad of amino acids
-provide energy when fat and carb(glycogen) stores are low - 5what are the 2 types of vitamins1. Fat soluble vitamins (A,D,E&K)
-mainly in fatty foods stored in liver and fatty tissues for use later
2. Water soluble vitamins (B&C)
-wide range of food, not stored in body so have to be taken daily - 6Examples of vitaminsC=protects cells and keeps them healthy
D= absorption of calcium
B1,2=helps break down and release energy from food
B6= helps form haemoglobin
B12=makes red blood cells - 7what do minerals do?they assist in bodily functions, tend to be dissolved by body as ions and are called electrolytes
- 8what does Fibre do?slows down the time it takes for the body to break down food and helps intestines by aiding digestion
- 9what are the symptoms of dehydration-blood viscosity increases (less blood to muscles)
-reduced sweating
-muscle fatigue and headaches
-increased heart rate
-decreased performance - 10what is glycogen loadingsix days before competition:
1.performer eats diet high in protein for three days and exercises relatively high intensity t burn off existing carb stores
2. then 3 days of high carbohydrates diet and little exercise - 11Creatine monohydrate-supplement used to increase the amount of phosphocreatine stored in the muscles
-phosphocreatine is used to fuel the ATP-PC
-meaning energy will last longer
-also improve recovery time - 12sodium bicarbonate-it is an antacid and can increase the buffering capacity of the blood (neutralise the effect of lattice acid and hydrogen ions)
-main aim is reduces the acidity within muscle cells to delay fatigue - 13caffeine-it is a stimulant so increases mental alertness and reduces fatigue
-improves mobilisation of fatty acids therefore sparing muscle glycogen stores
