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

Positive Energy

Balance

Negative Energy

Balance

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



>60 (13.5 x kg body wt) + 487 (10.5 x kg body wt) + 596

Very Heavy 2.3 2.0-2.6 2.0 1.8-2.2

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

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
