Transcript Ergogenic Aids

Ergogenic aids
Introduction
 Performance enhancement aids, commonly
referred to as ergogenic aids, this is a
generic term to describe anything that
enhances performance.
Ergogenic aids
 If a performer wears specific footwear for
your activity to improve your grip or wear a
Speedo LZR swimsuit you are making use
of performance enhancement aids/
ergogenic aids.

Remember that
 The VAST Majority of ergogenic aids are in
fact legal. Not all are negative or ;drug
cheats’ when hearing the term.
 Ergogenic aids are not a new thing in the
early years of the tour de france cyclists
consumed a cocktail of substances,
containing alcohol and speed
(amphetamine).
Because of the increase in
technology, the practice of
ergogenic aids has increased
So much so that the IOC (International,
Olympic Committee) and the WADA
(World anti doping agency) Has now
produced a list of ergogenic aids that are
banned and those that have restrictions.
Despite banned lists, use of ergogenic
aids has not stopped and in many
cases cheats are creating ‘masking’
drugs, which hide the use of the
banned substances.
Types of aids to performance
Dietary manipulation

PRo
Fluid intake
 P490
 Water intake during prolonged exercise
reduces the risk of dehydration and
optimises performance.
 Copy Figure 19.3 p490
Types of sports drinks
read page 490 for details
 Hypotonic drinks = 4% glucose
 Isotonic drinks = 5-7 % = same amount of
glucose as blood

ABM
 Hypertonic drinks = 19% glucose
Creatine supplements
 Creatine is made up of amino acids and in found
in some animal foods and naturally in the
liver/kidneys. It is stored in small amounts in the
mucles known as PC and is used to resynthesise
ATP.
 Athletes take creatine to increase PC levels they
therefore aid the ATP/PC system efficiency.
Legal or illegal?????
Creatine supplements
Human Growth Hormone (HGH)

HGH
 Stimulating bone,
cartilage and muscle
growth
 Increase blood glucose
levels
 Increases lipases for
breakdown of FFA’S Free
fatty acids
 Decreases overall body
fat
 Simulation of protein
synthesis in skeletal
muscle to enhance
healing after injuries.
Gene Doping

 Hard to detect
 Legal or illegal?????
Blood Doping
 Bllod doping key term definition:
‘Any means by which a persons total volume
of red blood cells is increased’
http://www.youtube.com/watch?v=8DTNgNizUQ
Recombinant Erythropoietin
(RH EP0)
 Key term definition
‘Erythropoietin (EPO) is naturally occuring
hormone which increses the bodys ability to
manufacture red bllod cells’
‘Rh EPO An artificial synthetic copy of
erythropoietin’
Rh EPO
 By ingesting Rh EPO you are producing the
same results as blood doping in that it
increases the production of red blood
cells/haemoglobin levels.
 Advantages disadvantages???
 Legal or illegal???
Cooling aids
 Used primarily prior to the activity to reduce
core body temperature in a bid to improve
performance, or after the activity in a bid to
improve performance, or after the activity in
a bid to improve the recovery process.
Cooling aids used






Cold air exposure
Water immersion/ice baths
Fan cooling
Cold water spraying
Body/head cooling jacket/vest
Cold therapy packs/ wraps/ ice packing in
damp towels.
Pre cooling
 Pre
 Usung ice jacket- aims to reduce skin temperature
and consequently core body temperature. Should
last between 8-30 mins.
 Resaerch indicates that cooling is advisable
before prolonged exercise in hot temperatures,
can help sustain intensity and speed– extend on
advantages p495
Post Cooling
 Used to treat injuries as part of recovery.
 RICE METHOD????


Ice
Compression
Elevation
Rest
All performance enhancement
