Q & A
Impact of Nutrition
Less time lost to illness
Optimal physical adaptions
Faster return time
Athlete Wellness
Athlete performance
Athlete rehabilitation
Nutrition is individualised
You need to tailor what you learn to suit your
personal needs
Needs will depend on
- age
- gender
- personal goals
- metabolism
- general health
Impact of Nutrition
Energy Balance – what is a calorie?
Calorie = unit of energy
Calories are the energy we acquire from food
number of calories in a food = the amount of energy in it
1g CHO = 4 kcal
1g PRO = 4 kcal
1g Fat = 9 kcal
1g Alcohol = 7 kcal
Energy Balance

Negative Energy

Energy Balance
Resting Metabolic Rate (RMR)
60-70% of daily energy expenditure
Synthesis, secretion and metabolism of enzymes and hormones
Maintenance of body temperature
Brain function
Work of cardiac and respiratory muscles
Cell function and replacement
Factors Which Affect Energy Requirements
1. Metabolic response to food- ingestion, digestion, absorption, transport
- Dietary induced thermogenesis (10% of energy expenditure)
2. Physical activity- varies the most
3. Growth- varies throughout lifecycle

Estimating Energy Requirements
Provide all the benefits of good
energy levels
Sufficient intake of macronutrients
Helps to achieve and maintain a healthy weight
Sufficient vitamins and
minerals provided
Estimating Calories
Most commonly used for estimating energy
requirements
Use age, gender and weight to predict RMR
Original equation derived on a study of 5000 healthy
adults
Method
1. Estimate RMR using appropriate equation
2. Multiply by a PAL factor for exercise
1 kg = 2.2 pounds
Your weight in pounds ÷ 2.2 = your weight in kg
e.g 180 pounds180 ÷ 2.2 = 82kg
Age RMR (Kcal/24 hours)
Years Males Females
10-18 (17.5 x kg body wt) + 651 (12.2 x kg body wt) + 749
19-30 (15.3 x kg body wt) + 679 (14.7 x kg body wt) + 496
31-60 (11.6 x kg body wt) + 879 (8.7 x kg body wt) + 829
>60 (13.5 x kg body wt) + 487 (10.5 x kg body wt) + 596

What is your PAL?
Sedentary or light activities:Sedentary occupation and lifestyle-Eating, Sleeping, Working, Cooking
Sitting
Light or moderately active: sedentary occupations but do regular physical activity 1 hour
Heavy/very heavy lifestyles:Regular strenuous work or leisure activity for several hours
What is your PAL?
Calculate Energy Requirements
Your daily calorie
requirements RMR x PAL=
Re-access your calorie needs every 4-6 weeks
They may change with
- weight change
- routine change
- training regime change

Calculate Energy Requirements Example
Working Calorie Requirements into Macros
How do we then divide calories
across macro needs?
1g CHO = 4 kcal
1g PRO = 4 kcal
1g Fat = 9 kcal
Example
DaveFirefighter46Workout 3-5 times a week86kg/189 lbs
Strength trainsModerate-high intensity1-2 hour sessions
Dave
Calorie needs = 3941 kcal CHO = ?? CHO = 5-7g/kg CHO = 430-602g
Example
Dave
Calorie needs = 3941 kcal PRO = ?? PRO = 1.5-2.0g/kg PRO = 129-172g
Example
Dave
Calorie requirement = 3941 kcal CHO = 430-602g CHO calories = 1720 – 2408 kcal PRO = 129-172g PRO calories = 516 – 688 kcal
Fat?? Upper range: 1720 + 516 = 2236kcal 3941 – 2236 =1705kcal 1705/9 = 189g fat
93.8 – 189g Fat
Lower Range: 2408 + 688 = 3096kcal 3941 – 3096 = 845 kcal 845/9 = 93.8g fat
Example
Dave
Calorie requirement = 3941 kcal
CHO = 430-602g CHO calories = 1720 – 2408 kcal
PRO = 129-172g PRO calories = 516 – 688 kcal
Fat = 98 -189g Fat calories = 845 – 1705 kcal
Example
Claire
Teacher 26 Workout 6-7 times a week 57kg/125 lbs
Endurance trains Moderate-high intensity 2-3 hours per training session
Example
Claire
Calorie needs = 2668 kcal CHO = ?? CHO = 8-10g/kg CHO = 456-570g
Example
Claire
Calorie needs = 2668 kcal PRO = ?? PRO = 1.2g/kg PRO = 68g
Example
Claire
Calorie requirement = 2668 kcal CHO = 456-570g CHO calories = 1824 – 2280 kcal PRO = 68g PRO calories = 272 kcal
Fat?? Upper range: 1824 + 272 = 2096kcal 2668 – 2096 = 572 kcal 572/9 = 63.5g fat
13 - 63.5g fat
Lower Range: 2280 + 272 = 2552kcal 2668 – 2552 = 116 kcal 116/9 = 13g fat
Example
Claire
Calorie requirement = 2668 kcal
CHO = 456-570g CHO calories = 1824 – 2280 kcal
PRO = 68g PRO calories = 272 kcal
Fat = 13- 63.5g Fat calories = 116 - 572kcal
Example
Your Sports Nutrition Plan
1. Work out your RMR
2. Multiply it by your PAL
3. This gives you’re your calorie requirements for 24 hours
4. Work our your CHO needs
5. Work our your protein needs
6. Multiply your CHO & protein needs by 4 to give calorie ranges for both
7. Use these ranges to calculate your fat range requirement
8. Use your macronutrient ranges to then plan your meals and snacks for
the day
