intermittent hypoxic training WADA status
legal
what do cooling aids do (2)

- increased blood pressure
cooling aids WADA status
legal
what is amount, composition, & timing of meals (pre & post)
Pre competition:
- eaten 2-4 hrs before event
- high in glycogen
- glucose immediately before exercise
Post competition:
- optimal time = within 2hrs after exercise
- rate of glycogen replacement is at its quickest - eat CHO rich meal
benefits of amount, composition, & timing of meals (1 + e.g.)
- good for performers who use glycogen as food fuel
- e.g. endurance athletes & games players
risks of amount, composition, & timing of meals (3)
- can have detrimental effect on performance if consumed to close to competition
- high blood glucose levels stimulate release of insulin that removes glucose from blood - can cause fatigue/hypoglycaemia
- possible conversion of carbs into fats
amount, composition, & timing of meals WADA status
legal
what is glycogen loading (4)
- glycogen stores depleted a week before competition
- by heavy raining - high protein, low carb diet
- body overcompensates for lack of carbohydrates
- stores more glycogen than before
benefits of glycogen loading (4)
- increased glycogen stores
- increased endurance capacity
- delays fatigue
- increases time to exhaustion by up to 30%
risks of glycogen loading (6)
- hypoglycaemia in depletion phase
- poor recovery rates in depletion phase
- lethargy & irritability in depletion phase
- gastrointestinal problems
- increased risk injury
- affects mental preparation pre-competition
glycogen loading WADA status
legal
What are the 3 ways to hydrate
- hypotonic drinks
- isotonic drinks
- hypertonic drinks
what are hypotonic drinks (2)
- lower concentration of glucose than blood glucose
- vital for prolonged exercise for when fluid replenishment is primary
what are isotonic drinks (2)
- equal concentration of glucose to that in blood
- promotes fluid hydration & replenishment of glucose during endurance events
what are hypertonic drinks (3)
- higher concentration glucose than blood glucose
- suitable for post activity recovery
- do not use during activity - high levels glucose cause dehydration - water needed to dilute CHO
benefits of hydration (5)
- replenishes glycogen stores
- decrease risk dehydration
- prevents increased body temperature (& possibility of heat exhaustion)

- first 2hrs post activity body most receptive to carb reloading
risks of hydration (3)
- possible conversion of carbs to fats
- bloated stomach
- dilutes sodium levels in blood - leads to fatigue
