Squash Nutrition

Okay, so when I discussed my post match cool down strategies yesterday it got me thinking of a fact sheet for kids that I designed in my nutrition and sport class. I have copy and pasted this below. I talk about what is most important for fuelling yourself for squash and for refuelling yourself after practice. I thought this would be of interest to many of you. Take a look and let me know if you have any questions.

 “Physical activity, athletic performance, and recovery from exercise are enhanced by optimal nutrition. (1)

    vitamins, minerals and other nutrients

      Contributes to your overall health and well-being
Are You Getting Enough (and the right type of) Carbs? 

THE BALANCED DIET AND CARBOHYDRATES
Glycogen (2)
o Is the storage of carbohydrates in the body
o is the primary fuel source for aerobic exercise
o Carbohydrate ingestion prior to exercise tops up blood glucose
stores along with muscle and liver glycogen stores
Low vs. High Glycogen Foods – The Glycemic Index (GI)(8)
o Is a ranking or carbohydrates on a scale from 0 to 100
o Determines how quickly and severely a carbohydrate food raises
the blood glucose levels following ingestion
o High GI foods rapidly and severely spike the blood glucose level o Low GI foods result in an improved maintenance of blood glucose
levels during exercise (5) 
Before Exercise
o Consume lower GI foods
During Exercise
o Replace fluid loss and consume (30 – 60 g/hour) carbohydrates to maintain blood glucose and muscle glycogen levels
After Exercise
o Consume higher GI foods to quickly replenish glycogen levels o How much energy did you burn? Focus shifts to replenishment which decreases recovery time
 
Low glycemic index rated foods gradually raise blood glucose levels and have proven health benefits (9)

BEFORE PLAYING SQUASH?

Key Components for Optimal Training, Performance and Recovery
Daily Carbohydrate Requirements: Variations Depending on Exercise Intensity and Duration (2)
o Low – 3-5g/kg body mass
o Moderate – 5- 7g/kg body mass
o High – 6-10 g/kg body mass
o VeryHigh-8-12 g/kg body mass

Prior to Exercise (3)
Food eaten before exercise should provide carbohydrates. It should also be low in fat and moderate in fibre to make digestion easier and reduce the risk of gastrointestinal discomfort. It must also be eaten with sufficient time to be digested and absorbed. The amount of time you have prior to exercise dictates what (and how much) food you should eat. The anticipated intensity and duration are also factors in determining how much fuel is required. During aerobic exercise (lasting 1 to 4 hours) 50 – 60% of energy comes from carbohydrates (1).
What are the optimal sources for fueling?
The following foods are suitable to eat 3-4 hours before exercise:
  •   Baked beans with bread
  •   Cereal with milk
  •   Bread with cheese/meat + a banana
  •   Yogurt with mixed fruit
  •   Pasta or rice with a low-fat based sauce (e.g., tomato, vegetables,
    lean meat) – healthy options: whole wheat pasta or brown rice The following snacks are suitable to eat 1-2 hours before exercise:
    Milk shake or fruit smoothie
    Sport bars (check label for carbohydrate and protein content) Cereal with milk
    Fruit-flavoured yogurt
    Fruit
    What can I consume if I have less than an hour before exercise?
    Sports drinks
    Carbohydrate gel 
    Sports bar
    What, when and how much do you eat when you perform & feel your best?
    Experiment to find the timing and amount that best suits your individual needs

After Exercise (4)
WHAT SHOULD I EAT AFTER MY MATCH OR PRACTICE?
The recovery process should focus on refueling the muscle and liver glycogen (carbohydrate) storage, replacing the fluid and electrolytes lost while building new muscle protein.
The goal of post-exercise recovery nutrition is replacing the body with the nutrients that were lost in a quick and practical manner that will optimize recovery and regeneration.
The main fuel used during moderate and high intensity exercise is muscle glycogen, so refueling reserves quickly is best accomplished through high GI foods.
What can I eat immediately after exercise (within the first hour)?
Consume a snack or meal that contains 1 – 1.5g of carbohydrates per kg of body weight in the first 30 minutes and again every 2 hours for 4-6 hours (2)
Consume 15 – 25g of protein

Items that contain 50g of carbohydrates

“It is important to remember that food eaten throughout the training week and
food
and fluid consumed

during the event is just
as important. Consuming food and fluid before exercise should be seen as an opportunity to fine tune carbohydrate
and fluid levels...”
