Let’s Recap- Lesson 7
➢Often we know what we need to do in order to change but
we don’t do it
➢We need to be aware of our bad habits
➢ It is possible to break bad habits but not immediately…it
takes time
➢There are many barriers which prevent us from changing-
lack of time, lack of motivation etc.
➢We can take action to overcome these barriers
➢Psychology is an important part of adapting new lifestyle
behaviours
➢ If you are having trouble implementing change, you should
be looking at incorporating SMART goals

Risk of Not Being Aware of Benefits of
Exercise● Good nutrition should go hand in hand with a good
exercise regime
● Each of them complements the other
● There are so many benefits to exercise and not exercising
is one of the leading causes of poor health
Physical InactivityIdentified by WHO
as 4th leading risk
factor for global
mortality

Introduction to Sports Nutrition
Carbohydrates
Provided by carbohydrate
Essential fuel for athletes
50-60% of diet Carbohydrates
Refined carbohydrates can be used to top up
your energy during exercise
Extra calories only needed if you are doing
regular VIGOROUS exercise
Don’t overestimate how many calories you are
burning via exercise
If you want to lose weight don’t increase your
carbohydrate consumption!!
How Much Carbohydrate Do I Need?
Exercise RDA Carbohydrate
Light activity (3-5 hours a
week)
4-5g per kg body
weight/day
Training 60-90mins/day 5-7g per kg body
weight/day
Training >90-120mins/day 7-10g per kg body
weight/day
Example:
Tom is 75kg and he goes running for 60mins daily:
5 x 75 = 375g CHO/ day…375 x 4Kcals = 1500Kcals in carbohydrate
Tracey is 60kg and she jogs 4 times a week (total 3.5 hours):
4 x 60kg = 240g CHO/day..240 x 4 = 960Kcals in carbohydrate
*Exercise increases your calorie requirements
Glycaemic Index
Tip:
Topping up low or empty glycogen stores after
prolonged or high intensity exercise is essential to
guarantee adequate stores for your next session.
Consume a high glycaemic index snack (providing
1g of carbohydrate per kg body weight) within 2
hours, or within 30 minutes if you plan to exercise
again within 8 hours
Choose Healthy Carbohydrates
Eat mostly:
Whole grain
breakfasts
Porridge
Potatoes, wholegrain
pasta and rice
Cous cous, noodle
Oatcakes
Sweet potato
Root Vegetables
Fruit
Popcorn (unsalted)
Eat seldom:
Jam
Honey
Desserts
Fizzy drinks
Sports gels and
bars (unless
extremely active)
Biscuits
*Watch fat content
of refined
carbohydrates
Protein
Most of us already eat too much protein
Needs easily met via healthy balanced diet
Eat protein regularly throughout day
High protein foods- red meat, chicken, fish, eggs,
cheese, milk, yoghurts, nuts and pulses
Including foods with 2g of Leucine immediately
after exercise will maximize muscle growth (e.g.
600ml semi-skimmed milk, 120g of beef, poultry or
seafood).
Protein Requirements
Population protein requirement g/kg/day
Normal activity levels 0.75-1
Elite male endurance athletes 1.6
Moderate-intensity endurance
athletes (exercising 4-5 times a
week for 45-60mins)
1.2
Recreational endurance athletes
(exercising 4-5 times per week for
30 min)
0.8-1
Football/team sports 1.4-1.7
Strength/ power athletes 1.5-1.7
Female athletes Approx. 15% less than males
Post Training ProteinResearch suggests
protein after a
heavy/strenuous
training session is
beneficial
0.2g/kg
body
weight
Food Protein (gs)
1 slice turkey/ ham/ chicken 7g
1 natural yoghurt (125ml pot) 6
Small tin tuna (100g) 19
2 low fat fruit yoghurts (125ml) 11g
1 egg 7
40g peanuts 10
500ml Lucozade recovery 18
Work it out:
My weight
is:….kg
My Protein
requirements
are …..g
Snacks For Sportspeople
50g Carbohydrate
and 10g protein for
after work out
250-350ml of milkshake or fruit smoothie
2 x 200g tubs of fruit-flavoured yoghurt
Bowl of breakfast cereal and milk
200g tub of fruit-flavoured yoghurt topped with 1 cup of breakfast
cereal
250g tin of baked beans or spaghetti plus 2 slices of bread
1 sandwich including cheese/meat/chicken in filling plus one
piece of fruit
1 tub of fruit flavoured yoghurt and a cereal bar
2 crumpets with a thick spread of peanut butter
250g (large) baked potato with cottage cheese or grated cheese
filling
150g thick crust pizza
Some sports bars (check labels) or Liquid meal supplements
(check labels)
Too Little Or Too Much Protein
Not enough protein:
Decrease in muscle mass
Longer recovery time
Depressed immune system
Too much protein:
Increased excretion of calcium in the urine
Increased protein as fuel
Weight gain
High fat diet
Replaces other foods in the diet
No evidence that >2g protein/kg body weight is beneficial
Put Theory Into Practise Decide do you want to lose weight or maintain weight
Multiply BMR x activity level- estimated energy
requirements (if very active energy requirements will be
higher)
How much Carbohydrate do you need? Choose your
activity level. Multiply the corresponding CHO g x body
weight in kgs
Multiply CHOg x 4kcals = energy from carbohydrates
How much protein 0.75g x body weight= Protein gs/day
Protein gs x 4kcals = calories from protein/day
Fat <35% total energy
Follow Food Pyramid and Calorie Count if you want to
lose weight
NB Make sure you meet energy and protein
requirements
Exercise RDA
Carbohydrate
Light activity (3-
5 hours a week)
4-5g per kg body
weight/day
Training 60-
90mins/day
5-7g per kg body
weight/day
Training >90-
120mins/day
7-10g per kg
body weight/day
ExampleKate is 25 and is 50kg. She is a healthy weight and wants to
maintain her weight. She runs 8km 3 times a week and does
weight training twice a week. Work out her requirements.
Energy Requirements (BMR x PAL):
Schofield: (14.8 x kg body weight) + 487
PAL 1.6
(14.8 x 50)+487=1227Kcals x 1.6 = 1963Kcals/ day
Carbohydrates: Activity 3-5times/ week- 3-5g CHO
50kg x 5g CHO = 250g CHO
Protein- 0.75g per kg body weight
0.75g x 50kg = 37.5g protein
Post work out protein snack 0.2g per kg body weight
0.2g x 50 kg = 10 g protein required post work out (see chart)
Fat
Limit fat as
per healthy
eating
guidelines
Choose
unsaturated fat
over saturated
fat
Iron
Adequate intake essential for athletes
Intense training can lead to iron losses
Females have greater requirements then males
Choose foods high in easily absorbable iron e.g. red
meat
Vegetarians and those on weight reducing diets
vulnerable to iron deficiency
Iron deficiency- fatigue, shortness of breath,
weakness….not good for sports!
Fluid Intake
Fluids lost through sweating
Stay hydrated to prevent:
Fatigue
Impaired performance
Drink 300-600ml fluid before exercise
Aim to drink 150-200ml fluid every 10-
15mins when exercising
Drink after exercise to hydrate yourself
Are you drinking
enough?
Weigh yourself
before and after
exercise. Try to
keep weight loss
<0.5kg
Drink 1.5L fluid
for each kg lost
What Should You Drink??
Hypertonic sports drink
Isotonic Sports Drink
Water
Homemade CHO/salt solution
The fitter you are the
more you
sweat….REHYDRATE!
Thirst is a poor
indicator of
dehydration
Calcium
Good sources of calcium:
Low Fat milk
Low Fat yoghurt
Low Fat cheese
Smoothies
Custard
Milk pudding
Calcium enriched soya milk
Tinned fish (with bones)
Green leafy veg
Nuts
Dried figs
Calcium-enriched juice
Sports Supplements
Protein supplements
Usually claim:
Enhanced recovery
Decreased fatigue
Increased muscle mass
Pros
Provide essential amino acids needed to maximise
muscle growth
Portable and convenient
Cons
Expensive
Protein needs can be met through food alone
Whey protein is also found in food- milk, beef, poultry,
seafood
Sports Supplements
Amino Acids
Bought individually or in combination with other ergogenic aids
such Creatine
Claim to stimulate growth hormone and inhibit the breakdown
of muscle
Yet to show any performance enhancement
Not recommended
Large doses >30g per day may negatively affect athletic
performance
Protein and amino acid supplements are no more or no less
effective than food when the athlete’s calorie intake is enough
to increase lean muscle mass
Sports Supplements
Sports gels- concentrated energy
Benefits:
Help delay fatigue and improve endurance performance
Good fuel source for prolonged exercise >90minutes
High calories, not appropriate for calorie restricted diets
Over-consumption- gastrointestinal upset
Sports bars- portable snacks or meal replacements
Contain protein, fat and fibre
+/- herbal additives and/or caffeine
Benefit
Delay fatigue
Sports bars offer a pre or post exercise snack where appetite is
suppressed or other foods are not available
or easily tolerated.
In Conclusion
Everyone should be more active on a daily
basis
Children should aim to be active 1 hour / day
Adults should be active 5 x 30mins/ week
Exercise should be increased for weight loss
Exercise helps to prevent obesity, Type 2
Diabetes, CVD as well as mental health
problems
Diet should be adapted slightly for sports
people
Diet supplements are not necessary for active
people
Elite athletes should consult a sports Dietitian
