SPORTS NUTRITION SEMINAR – DAVE BOX
THE EQUATION IS SIMPLE : WHAT YOU PUT IN, YOU
GET OUT –FACT!!!
Exercise degrades the body
Good
nutrition and supplementation = repair and recovery
Body Must Have :
1)
Protein
– to rebuild muscle
2)
Carbohydrates
– to burn fat
3)
Essential
Fatty Acids – heart and supple joints
4)
Vitamins/
Minerals/Water – Electrolyte balance
5)
Anti-Oxidants-
combat free radicals produced by exercise
BENEFITS OF OPTIMUM NUTRITION
BENEFITS OF SPORTS SUPPLEMENTS COVER 4 AREAS
1)
Increased
tolerance for the type or magnitude of the activity
2)
General
energy
3)
The
ability to recover more effectively
4)
Enhancement
of the normal physiological scope of the human body
COMPONENTS OF GOOD SPORTS NUTRITI
Phases include: FUELLING, HYDRATING, REFUELLING,
REPAIRING, RECOVERY
FUELLING
1hr before- liquid form
fuel tanks
loaded – glucose
2 fuel
tanks – carbs & fats
fat burns
in the flame of carbs, you cannot burn fat when carbs run out.
Carbs
converted into the body & stored as muscle glycogen.
HYDRATING
before/during/after
crucial
electrolyte balance – every 15 minutes during exercise.
minerals,vitamins,water
REFUELLING
restore
glycogen
30 min
window (this is the only opportunity you have so use it!!!)
muscles
most receptive towards being refilled now
REPAIRING
long term
damage
protein 1&
half – 2 hours / rebuild. High quality protein assists muscle cells to repair
themselves. Every activity in life damages muscle cells.
RECOVERY
benefit
=injury ratio, will be reduced with supplementation
lactic acid
removal, through warm down and anti oxidants into the system.
increase
glycogen re-synthesis, energy rises
reduce
muscle tiredness, together with protein
anti
oxidants/free radicals (athletes breathe in more oxygen than a non-active
person- more carbon dioxide)
10 STEP SUGGESTIONS TO FOLLOW:
1)
Your
body is very similar to a car; it needs fuel to function effectively
2)
The
most effective way to fuel up your body is with energy-rich nutrients
3)
Recharge
your battery
4)
Tap
into your reserve fuel tank for extended bouts of physical activity
5)
Hydrate,hydrate
and re-hydrate
6)
Protein
is key to muscle maintenance and growth
7)
Proteins
vs. Carbohydrates
8)
Maximising
your fuelling and refuelling efforts
9)
Reducing
recovery time
10)
Use
supplementation to your advantage
WORD ON GI = KEY IS
SEROTONIN
Carbs converted to
blood sugar (1-100)
Crash = Lethargy (eat
more)
Sustained energy
(ideal for athletes)
The lower
the index the better!!!!!
FURTHER MOOTING POINTS ON SPORTS NUTRITION
1)
THE IMMUNE SYSTEM
Most important weapon in fight against disease.
Thymus is the major gland of IS and only IS can cure disease, so nutrients are superior
to drugs to strengthen IS. We as
athletes are vulnerable as the IS can be weakened by heavy training and junk
food. Highly trained athletes at peak
often have weak IS
2)
CAFFEINE FACT
Small amounts of natural caffeine helps
exercise, but large amounts of processed caffeine is bad for the body. Chemical
caffeine releases hormone to take water out of the cells. Each 1% of
dehydration decreases performance by 8%.
3)
CREATINE ISSUE
Creatine is made up of amino acids (natural in
diet) comes from food and gets delivered to the blood stream and skeletal
muscles. Taking 20 grams of creatine in
powdered form is the equivalent of eating 10 kilos of raw streak. Trend is
against taking creatine now as John
Quinn (coached Australian Olympic Sprints and ex national rugby performance
director) complained of increased incidence of injuries particular in Achilles,
hip and patella tendons. Also found that we excrete salt & water could
affect renal probs. French & Irish rugby unions advise against it , Arsene
Wenger of Arsenal has banned use of it, together with
4)
SUGAR DRINKS SOLD AS ENERGY/SPORTS
DRINKS
Avoid carbonated drinks = system does not
respond well to carbon dioxide-slow absorption.
Sugar (refined) is unhealthy. Sugar triggers a hormonal response which
releases insulin. This stores sugar and body is put into storage mode at a time
when body needs to be in release mode. Sugar slows hydration of the
cells/muscles which need re-hydrating. Finally large proportion of carbs do not
get into the liver or muscles to store as glycogen.
