Recovery – nutrition essentials for better performance

Between each workout, game or race the body needs to adapt to the physiological stress that has just been applied, so that it can recover and become fitter, stronger and faster. This can be challenging when an athlete has two or more session each day, for prolonged training periods and for multiple event sports.

What’s happening during recovery?

  • refuelling of muscle and carbohydrate stores
  • replacing fluids and electrolytes lost in sweat
  • manufacturing new muscle protein and blood cells
  • allowing immune system to manage damage caused by exercise

Nutritional management of recovery:

  1. Replace muscle carbohydrate (glycogen) – with in 1 hour of exercise: 1-2g/kg – this is when carbs are most efficiently utilised by the muscles. This is especially important if the next training session is within 8 hours.
  2. Rehydrate – dehydration negatively impacts on performance during subsequent sessions. Aim to replace fluids lost with 120% fluids with electrolytes. Sodium reduces urine losses and induces thirst, therefore encouraging increased fluid intake.
  3. Build and repair muscle – High intensity exercise leads to breakdown of the muscle. The recovery phase is an opportunity for building muscle. 15-25g high quality protein within 1 hour increases muscle building. Adding carbohydrate enhances recovery of muscle by reducing muscle breakdown.
  4. Protect immunity – immunity is suppressed by intense training, making athletes more susceptible to infectious illnesses. Carbohydrate is an immune protector as it reduces the stress hormone response to exercise. Carbohydrate also fuels the activity of the immune system’s white cells.

Supplements for recovery

Many athletes rely on sports supplements during and immediately post exercise, then double up with a meal soon after. This is fine if there are very large calorie needs, however, for moderate to low energy needs this is excessive. Food provides the same plus additional benefits to supplements eg. iron, calcium, fibre, antioxidants etc.

Good foods for recovery – providing carbohydrate & protein:

Rice pudding, milkshake, breakfast cereal with milk, beans on toast, cheese roll, jacket potato with cottage cheese, tuna wrap. Any balanced meal with protein, carbs and veg.

Post exercise shakes have their place, but watch the extra calories!

Nutrition for Young Athletes

Why a nutritious diet is needed:

images

  • Normal growth and development
  • Healthy, strong body
  • Energy for everyday activities – school, gymnastics training
  • Repair of muscles following demands and stresses of training and competition

Main components of the diet:

Hydration:

bottled-water

  • as important as food
  • Overheating and dehydration can be dangerous (heat stroke)
  • Low levels of dehydration: reduced strength, stamina, concentration

Carbohydrate:

  • Supply energy for musclesSTARCHY
  • Immunity
  • Growth
  • Focus on wholegrain bread, pasta, rice, fruit, veg
  • Especially important before and after exercise for muscle energy

Protein:

  • For muscular strength & power, muscle repair & maintenance
  • Focus on lean protein: chicken, fish, eggs,
  • dairy, beans, seeds, nuts

Healthy Fats:

  • Important for healthy heart, nervous system, hormones etc.
  • Focus on healthier fats from olive oil, oily fish eg. Salmon, avocado, peanut butter etc.

Vitamins & Minerals:

  • Calcium – strong bones
  • Iron – needed for blood cells to transport oxygen to muscles
  • Vitamin D – bone development, also implicated in long term health issues
  • B vitamins – energy production & protein metabolism
  • Omega 3 fats – oily fish, for brain development, heart health, vision etc.
  • Generally, supplements not needed if child has varied diet
  • Consider fish oil supplement (omega 3 fats) if intake of oily fish is less than once per week
  • Consider Vitamin D supplement if always wears sunscreen in summer

Pre – exercise fuelling:

  • Aim to have a meal or a substantial snack a few hours before:
    • Pitta/crumpets/toast with jam/honey/peanut butter + milk
    • Jacket potato + tuna/baked beansshutterstock_81803002
    • Baked beans on toast
    • Boiled egg and toast
    • Porridge, milk and raisins/berries
    • Breakfast cereal with milk
    • Bread roll with cheese/meat filling + banana
    • Pasta, rice or noodles with tomato sauce, lean meat eg. chicken, vegetables
  • Up to 1 hour before
    • Fluid for hydration: 200mls fruit juice/water/skimmed milk

 Early morning sessions: If training or competition is first thing in the morning, it is probably not possible to have a meal 3-4 hours before. In these circumstances, have a good meal the night before, then a snack and fluid 1-2 hours pre exercise eg. breakfast cereal and milk, fruit and yoghurt, smoothie or milkshake.

After exercise:

Ensure your child has a snack, or a meal following training. Carbohydrates replenish the muscles with glycogen for energy, while protein repairs and rebuilds muscle tissue. Sports protein shakes or supplements are unnecessary and not advised.

Post-exercise snack ideas (follow within a few hours with a meal):

  • Homemade shake – blend 200ml milk, tablespoon yoghurt, banana, tablespoon honey
  • Low fibre breakfast cereal  eg. Cornflakes/Rice Krispies and milk
  • banana and yoghurt/milk
  • Bread roll or sandwich with cheese/meat/fish filling

Rehydration

It is highly likely that your child will finish training with some degree of dehydration, therefore it is important to replace these fluids as soon as possible after the session. Aim for 200ml fluid with an hour of finishing.

Body image and Disordered Eating

In some sports there is pressure to ‘not get fat’/stay lean or to bulk up to enhance performance Eg. Gymnastics or rugby.

Any such pressure can have the opposite effect – unhealthy eating patterns, restrictive eating (anorexia), or bingeing (bulimia).

Poor nutrition, resulting in weight loss, can cause anaemia, reduction in muscle power and performance, weak bones, poor concentration and increased injury risk

Tips for parents:

  • Do not weigh your child (unless specifically asked to do so for medical reasons)
  • Do not discuss calories or fat, unless raised by your child.  Approach in a positive manner e.g. food gives us energy for exercising and being strong. Healthy fats are important for us to be healthy.
  • Talk about food being nutritious, for making us strong, repairing cuts in our skin, building our muscles, giving energy for running fast etc.
