dietary considerations
no single food group is able to provide all the nutrients the body
needs so it is important to eat a variety of foods
5 main foods groups
bread rice potatoes pasta and other starchy foods
fruit and vegetables
milk and dairy food
meat fish eggs beans and other non dairy sources of protein
food and drinks high in fat and/ or sugar
proportions for this are shown in the food wheel
should try to choose different foods form the first four groups every day
failing to maintain this val;acne could result in the following dietary imbalance or deficiencies
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
CALORIE: a unit that measures heat or
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
