What are the recommended carbs for a balanced diet
55-60%
what are the recommended fats for a balanced diet
25-30%
what is the recommended protein percentage for a balanced diet
10-15%
What is the glycemic index
( GI ) a measurement carried out on carbohydrates containing foods and their impact on our blood sugar
what is low gi
before competition or training e.g grain breads, toasted muesli, peaches, cashew nuts
what is high gi
when an event is longer than 50-60 mins
what is carbohydrate loading
a strategy used by endurance athletes to maximise the storage of glycogen in the muscles and liver. To carb load successfully is gradually cutting down on training at the same time keep to their normal diet so that only carbohydrates are eaten to ensure steady muscle glycogen levels
when are depleted glycogen stores replenished
within 15 minutes after excercise
why is caffeine considered a diuretic,
because it causes people to lose fluids
how does caffeine affect the body
dehydration
what are the positive effects that caffeine has on an athlete
contains antioxidants, stimulates respiration, intensifies muscular contractions
what are the negative effects caffeine has on an athlete
anxiety, headache, risk of dehydration, early fatigue
what are the positives of using sports drinks
- enhanced levels of electrolytes
- provide nessecary energy source
- speed up absorption & water retention in the body
what is isotonic
replenishes electrolytes
what is one electrolyte that assists with fluid regulation
sodium
what is the time frame after exercise that an athletes muscles are the most receptive to glycogen replenishment
the first 15 minutes
why is nutrition after exercise important
- helps to provide recovery
- helps to increase impact of exercise
- helps repair and rebuild muscles
what are the symptoms of dehydration
extreme thirst, very dry mouth
what are the symptoms of heat exhaustion
confusion, dizziness
what are he symptoms of heat stroke
high body temp, rapid breathing
what are two benefits of carbohydrate gels
- replenishes electrolytes
- increased energy
what role does protein play in post- exercise nutrition
- important for muscle contraction & repair
- way to develop and maintain skeletal muscle
- promotes glycogen synthesis
what are meal examples 3-4 hrs prior exercise
- crumpets
- baked beans
- breakfast ceral
what are meal examples 1-2 hrs prior exercise
milkshake/ smoothie
yogurt
sports bar
what are meal examples less than 1hr prior exercise
carbohydrate gel
cordial
jelly lollies
fluid replacement info
~ thirst is not a good indicator of fluid needs
~ drink half a glass of fluid every 15 mins b & a exercise
~ cold drinks are absorbed quicker
~ plain water is the best drink of all
~ when finished event, replace fluids lost
what causes fatigue
depletion of muscle fuel stores
hypoglycaemia
dehydration
what are ergogenic aids
a technique or substance used for the purpose of enhancing performance
how do steroids benefit an athlete
increase muscle strength
increase body size
increase healing rate
what types of athletes benefit from steroids
athletes involved in power sports e.g weightlifting, throwing, sprinting events
what does epo do
- regulates red blood cell production
- helps the athlete to work at a faster rate of aerobic respiration
- athletes that benefit are aerobic ( long distance ) or anaerobic ( short distance ) athletes.
what are the two types of blood doping
autologens and homologens
what are epo’s effects on performance
< stimulates bone marrow to produce more red blood cells
< higher red blood cells means better oxygen transport
types of athletes who benefit from epo use
endurance athletes
medical uses of epo
- cancer
- HIV
- renal failure
- pre/ post surgury
side effects of epo
- fever
- seizures
- nausea
- headaches
- anxiety
steroids effect on performance
used to create muscle bulk, strength and fast muscle recovery

~ in the middle you have most control and perform at your best
how can you improve attention
centred breathing
mental rehearsal
positive self talk
describe mental imagery
when athletes visualise themselves flawlessly performing a skill or competition event such as visualising yourself jumping far in long jump or throwing a free throw goal in basketball.
what is motivation
the reason for participating in an activity, learning the skills involved , training and practising and dedicating effort to improvement
what is intrinsic motivation
comes from within, occurs when factors such as enjoyment, satisfaction, improvement and enhanced feelings of self worth are the primary motivation for performance
what is extrinsic motivation
has an external focus, usually involves some form of material benefit such ad financial reward, awards and trophies, glory & recognition
