diet and nuturiton Flashcards
carbs
two types
simple-found in fruits
quicker to digest
complex-take long time to digest
found in plant based foods
funtion of carbs
main fuel soycre for high intensity/analerobic work and low intensity
only fuel source broken down anaerobically
carbs digested then transferred into glucose
glucose stored in mucles nd liver as glyocgen
fats
saturated-found in savoury foods
too much causes excessive weight gain, limits flexibility and leads to health isses e.g CHD
leads to high cholesterol levels
LDL and HDL
LDL-lead to fatty deposits developing in arteries
HDL-takes cholesterol away and to liver where it is disposed of
trans-found in meat ad dairy products
can lead to high blood cholestrol levels
proteins
energy source for long suration, low intesnity exercise
combination of Amino acids
imporat fro muscel growth and compare
make enzymes and hormones
used by more power athletes
vitamins
D
C
B
vitamins
essential nurtirents
fat soluble viatmins-ADEK
stored in fatty foods e.g dairy foods
waver soulble vitamins-b and c
found in fruits
fibre
slows down time it takes to break down food
slower sustained release of energy
water
transports nutruites, hormones and wast products around body
regulates body temp
water keeps you from overheating
once body loses water, dehydration takes place
what happens as a result of dedydation
muscle fatigues and headaches
increased HR, lower cardaic output
decreased performance/decreased reaction time
MID
objective data
data that is facts and measurable
subjective data
based on opinions, assumptions
validity
when test measures what its actaully set out to do
reliability
whether the tests are consistenct ancd can be repeated acuurately
hint; repetead and reliability start with R
warm up
3 stages
1.cardiovascualr endurance-gently increases HR, increases cardiac output, vascualr shunt more blood sistribution to working msucles
2.stretching
ballistic-jumping movemnts
active-focuses on one joint pushing it beyond its resistance
static-no movement
passive-external force used
PASB
3.movemnt patterns
e.g practing shooting in netball
psychotloical effects of warm up
reduces risk of injury as increases elasticty oof muscle tissue
release of adrenalien increases HR
cool down
some form of light exercise allows oxygen to be flushed through muscles removing and oxiding latic acid
too much alctic acid, performance to deteriornate
priniples of training
Specificity
Progressive
Overload
Reverslibiity
Recovery
