The best exercise foods

The best exercise foods

As any elite athlete will testify, your training is only as good as the food that you use to fuel it. But what are the best exercise foods pre-workout, during, and post-workout?

How would the marathon runner fare if they neglected to load up their carbohydrate stores before a 26.2 mile (42.2km) race? Would a bodybuilder achieve the gains they desire on a diet bereft of protein, which is key for building muscle? And can we expect to train at our best if we eschew good nutrition for junk food?
Clearly, correct dietary choices are extremely important to maximize training gains, especially in your pre and post-exercise eating. Nutrition for sport and exercise is a vast subject but for the purpose of this article, we will focus on what to eat before, during and after exercise — which makes a huge difference to your performance and recovery. This feature focuses on:

Correct food choices before different exercise sessions

How to maximize your recovery between workouts
Food and fuelling suggestions for when you’re on the go
Before exercise
If your nutrition is poor before your workout then you are guaranteed to feel lethargic and tired and will be unable to get the most out of your training session. Whether your session is in the pool, in the gym, at a yoga class or on the trails, you will always need correct fuelling.

Before a cardiovascular session

Ideally you should eat two hours before cardiovascular exercise to allow for digestion. Eat a low fat meal containing some good quality protein (for example lean meat or fish), together with some carbohydrate that has a low to medium glycaemic index. Glycaemic index or GI is a ranking system for different foods based on the speed that they enter the bloodstream. The higher the index value, the faster the food enters the bloodstream for example; glucose has a GI of 100. The lower the value, the slower the food enters the bloodstream and a more sustained energy release is achieved for example; porridge oats have a GI of 49, and so will enter the bloodstream more slowly than glucose.

So, try to target 30g of protein combined with 1.1g of carbohydrate per kg of bodyweight.

Before a resistance training session

Your pre-resistance training session will not be dissimilar to your pre-CV workout, but you can add more carbohydrate if your session will be very intense.
For example, target 30g of protein combined with 1.1 to 1.5g of carbohydrate per kg of bodyweight.

During exercise

Your energy requirements during exercise are dependent upon the duration of your workout. Solid food is unlikely to be very attractive and digestion will be slower than fluid and sweat losses can be in excess of one liter (33.8oz) per hour in hot conditions, so hydration is likely to be your primary concern. However, a drink can also include top-up carbohydrate to maintain your fuel stores.

During a cardiovascular  or resistance training session

You may need top-up fuel to help sustain your energy levels if your workout falls into one or more of the following categories:
It’s in excess of one hour
It’s extremely intensive
Your pre-exercise fuelling has been limited

The most palatable fuel to consume during exercise is a drink, which has the added benefit of aiding your hydration. For shorter sessions, a glucose replacement energy drink is ideal but if you are exercising for well over an hour, for example when you are competing in a long distance race, then a specialist drink that contains a combination of quick energy (glucose — high GI) and slower-release energy (more complex carbohydrate — low GI) is more suitable.
