what is an example of a complex vs simple carbohydrate
complex- starch

what does GI mean
glycaemic index refers to how fast a food is digested and impacts blood glucose levels
what are the benefits of hydration drinks
hypotonic- lower sugar levels than in blood. good for hydration to reproduce sweat and prevent headaches
hyper tonc
evaluate the use of creatine as an ergogenic aid
increases phosphocreatine stores and glycogen stores in the muscles, therefore generates more ATP for aerobic respiration which increases endurance and helps improve recovery times.
can cause weight gain, muscle cramps, diarreah.
evaluate the use of caffeine as an ergogenic aid
stimulates metabolism of fats for energy, reduces perception of fatigue and increases concentration and alertness however can cause headaches, insomnia and heart palpitations, diuretic
evaluate the use of nitrates as an ergogenic aid
cause dilation of the blood vessels which increases venus return and performance and delays fatigue as more efficient aerobic respiration causes headaches, dizziness
evaluate the use of bicarbonates as an ergogenic aid
component of the major buffering system as neutralise lactic acid and delaying OBLA which reduces fatigue and increases anaerobic performance, can cause nausea
what is the role of calcium
strengthens bones regulates muscle contractions
whats the role of phosphorus
helps body make ATP, makes proteins for growth
whats the role of iron
makes haemoglobin
whats the role of sodium
contract and relax muscles
whats the role of vitamin A and D
fat soluble vitamins. vitamin D keeps bones healthy, vitamin A keeps immune system healthy,
whats the role of vitamin C and B
water soluble, vitamin C helps heel wounds, vitamin B helps with cell metabolism and energy levels
whats the role of fibre
helps keep digestive system healthy
whats the role of water
rids waste products
