Title: Ergogenic aids


1
Ergogenic aids
  • An ergogenic aids is any substance that aids
    performance

2
  • Nutritional aids
  • Carbohydrate loading
  • Pre event meals
  • Post event meals
  • Food fluid intake during exercise

Hormones and anabolic steroids
ERGOGENIC AIDS
Nasal strips
Caffeine
Alcohol
Creatine
Blood doping and
erythropoietin (EPO)
3
Carbohydrate loading
This process involves the muscles super
compensating and increasing glycogen stores. The
athlete consumes a diet high in fat and low in
carbohydrate. After 3 days, training is tampered
down and athlete consumes a high carbohydrate
diet which increases muscle glycogen levels
BENEFITS long duration aerobics e.g. marathon
runner
Increase in fat
Normal athlete
Running
After 20 minutes
Decrease in carbohydrate
4
Carbohydrate loading
Increase in carbohydrate due to extra glycogen
stores
Increase in fat
Carbohydrate loading
Running
After 20 minutes
End of race
Decrease in carbohydrate
  • RISKS
  • Training without sufficient stores is very
    difficult and quality may be lost in the
    run up to competition
  • - Danger of depleted stores if you dont follow
    the correct diet prior to competition
  • - Athlete may be gain weight because of water
    retention

5
DIETARY MANIPULATION
  • PRE-EVENT MEALS
  • Pre event meals are eaten two four hours
    because it ensures that liver glycogen stores are
    high.
  • Who benefits - game players/aerobic athletes as
    they rely on the breakdown
    of glucose for energy
  • Risks -Hypoglycaemia (large amount of blood
    glucose stimulates insulin to remove the
    glucose)

6
DIETARY MANIPULATION
  • POST-EVENT MEALS
  • The best time to consume a post-event
  • meal is as soon as is practical after the
    event.
  • Who Benefits activities that utilised
    carbohydrate as an energy source.
  • Risks none

7
fluid intake during exercise
Dehydration fatigue The body sense of thirst
is a poor indicator as the body becomes thirsty
after dehydration therefore athlete should
replace fluid at every opportunity
3 types of sports drink Hypertonic
Contain large amounts of carbohydrates to
provide energy Isotonic Contains around
the same amount of carbohydrate as contained
in the blood Hypotonic Contains less
carbohydrate. Massages
8
Other aids to performance
  • CREATINE
  • Increasing the amount of creatine in the diet,
    the performer can maximise the amount of
    phosphocreatine.
  • Who benefits 100m sprinters, which stores
    allows athletes to perform longer greater amount
    of PC stores
  • Risks Strain in organs and increase in
    dehydration
  • CAFFEINE
  • Can help improve mental alertness, concentration
    and reaction time
  • Benefits endurance athletes due to potential
    increase in fat metabolism
  • Risks increase nervousness, anxiety and
    increase in dehydration

9
Other aids to performance
  • ALCOHOL
  • a relaxant in quite small quantities
  • absorbed into the body as an alternative to water
    therefore causes dehydration
  • quite small quantities of alcohol can cause a
    drastic loss of performance
  • Darts player drink to control nerves and feel
    more relaxed

10
Other aids to performance
  • BLOOD DOPING
  • Involves removing red blood cells from the
    body and storing them and allowing the body to
    replace them . The process takes about 5 weeks
    after which the original red blood are
    reintroduced to the body. Therefore more there
    will be an increase the amount of oxygen reaching
    the working muscles
  • ERYTHROPOIETIN
  • Is a hormone that stimulates the body to create
    more red blood cells
  • Risks
  • - Increase in blood viscosity can put a huge
    strain on the heart
  • - Blood clots and heart failure have been
    reported

11
Other aids to performance
  • Hormones and anabolic steroids
  • Anabolic steroids (nandralone) are thought
  • to increase muscle mass and help recovery.
  • Who benefits High intensity short duration
  • benefit (weight lifters)
  • Risks
  • -effects the balance of sex hormones,
    testosterone oestrogen
  • - Suffer from acne, weak joints aggressive
    tendencies
