- malnutrition: this is physical weakness resulting from insufficient food or
an unbalanced diet
- obesity: this is a condition of being extremely fat or
overweight, which frequently results in health problems
- anorexia: this is an eating disorder primarily occurring in girls and women, related to a fear of gaining weight,
self starvation and distorted body image
- specific diets
- a starting point for any diet must primarily be that it is balanced
- however there may be particular occasions when a diet may need to be adjusted or even adapted for particular performers and particular activities
- levels of participation
- eating food is necessary to provide the body with energy
- eating the right foods will ensure that you have enough energy and that you
are able to maintain the correct body weight for you particular needs
- energy is need by the body even when it is at rest
- when you become more active your metabolic rate
is affected and you will need to balance the
requirements your body has taken in with the
amounts that are being used up
- METABOLIC RATE: the
minimum rate of energy
required to keep all of the life
processes of the body
maintained when it is at rest
- the number of
calories needs to
balance because if
you have a higher
intake than output
you will tend to put
on weight and if you
are very active you
will need to make
sure that you are
providing your body
adequately

eery production in the body
- when to eat is also a factor you need to
consider carefully
- before activity: do not eat too close to performing, try to wait about 2 hours after eating
- during activity: generally you shouldn't eat during activity but
sometimes light and in small quantities e.g. banana would be fine
- after activity: you should try to leave the same 2 hour gap as you did before the activity
- liquids may need to be taken before during and
after the activity to avoid dehydration but don't
take too much liquid immediately after finishing
as this can result in discomfort
- carbohydrate loading
- this is a particular dietary plan that endurance athletes mainly marathon runes use involving eating plenty of starch rich foods such as pasta in the week before an important competition or event
- the starch increase the amount of glycogen in the muscles which can help to delay tiredness and can improve performance in the
end stages of a competition as its a slow release form of energy
