    _ increased risk of cancer
  • physiological aid
    a group of ergogenic aids used to increase the rate of body adaptation to improve performance
  • Blood doping
    the illegal process of removing blood cells from an athlete; the blood cells get stored and become replenished over time; the old blood cells are injected prior to the event
    e.g. endurance athletes
  • blood doping benefits
    + increased red blood cell and haemoglobin count
    + improved aerobic capacity / VO2 max
    + greater oxygen carrying capacity
    + delayed OBLA
  • Blood doping risks
    _ infection
    _ increased risk of heart attack
    _ increased blood viscosity
    _ decreased cardiac output
  • Intermittent Hypoxic Training (IHT)

    interval training where work intervals are under hypoxic conditions
    -> 15 - 90 minutes -> 4 - 8 weeks of training
    e.g. endurance or altitude athletes
  • IHT benefits
    + acclimatisation for altitude events
    + increased buffering capacity = delayed OBLA
    + increased red blood cell and haemoglobin count
    + improved VO2 max
  • IHT risks
    _ loss of motivation and disruption to training
    _ benefits are lost quickly
    _ dehydration
    _ reduces speed and power output
  • Cooling aids
    a range of products used to reduce core temperature, treat injuries and speed up recovery
  • thermal strain

    additional pressure placed on the body due to an increased temperature
  • Types of cooling aid
    Before training: ice vests, cold water immersion
    During training: ice towel, fans, cold water spray
    After training: ice baths, ice packs, cryotherapy chamber
  • before training cooling aid benefits
    + reduce core temperature
    + reduce thermal strain
    + sustained intensity
    + delay cardiovascular drift in hot conditions
    + delay fatigue early
  • before training cooling aid risks
    _ reduced heart rate
    _ inaccurate perceived exertion
    _ incorrect pacing strategies
  • during training cooling aid benefits
    + reduce skin temperature
    + removal of heat
    + increased time to exhaustion
    + reduced thermal strain
    + minimise swelling
  • during training cooling aid risks
    _ not always practical
    _ reduced muscle temperature can limit contractions
    _ inaccurate perceived exertion
  • after training cooling aid benefits
    + reduce swelling
    + treat injuries
    + allow vasoconstriction
    + speed up lactate removal
    + reduce the effect of DOMS
  • after training cooling aid risks
    _ tissue damage
    _ nerve damage
    _ ice burns
  • dehydration effect on performance
    -> decreased regulation of heat
    -> increased blood viscosity
    -> increased heart rate
    -> increased fatigue
    -> loss of electrolytes
    -> decreased cognitive function and skill level
  • dehydration
    a loss of water in body tissue which is mainly caused by sweating
  • glycogen / carbohydrate loading
    the manipulation of carbohydrate intake prior to competition to maximise glycogen stores for endurance
  • Glycogen loading steps
    Day 1: glycogen-depleting bout of endurance exercise
    Day 2-3: high protein, high fat diet
    Day 4: glycogen-depleting bout of endurance exercise
    Day 5-7: high carbohydrate diet with tapered or reduced training
  • Glycigen loading risks
    _ poor recovery
    _ hypoglycaemia
    _ increased risk of injury
    _ affects mental preparation
  • hypoglycaemia
    low blood glucose levels associated with dizziness, increased heart rate and shaking
  • Hypotonic sports drinks
    2 - 4 g/100ml of carbohydrates
    <50 mg of sodium per 100ml
    most effective hydration
    = low-moderate exercise under an hour
  • Isotonic sports drinks
    6 - 8 g/100ml of carbohydrates
    46 - 69 mg per 100ml of sodium
    moderate effective hydration
    = moderate exercise over an hour or intense exercise over half an hour
  • Hypertonic sports drinks 

    > 10 g / 100ml of carbohydrates
    rare electrolytes (sodium)
    least effective hydration
    = recovery after exercise to replace lost glycogen
