Emily says that throughout the day, you want to be consuming a lot of fluid to ensure that you’re hydrated before the match, which could include food as well as drink.
A study within elite football1 suggests dehydration can lead to cardiovascular strain, reduced cognitive function, heat exhaustion and increased perception of effort – so you might feel that the exercise is harder than it actually is. “This study also suggests that dehydration can reduce technical skills, such as dribbling or skilling past players on the pitch,” she explains.
It can all depend on your weight and body size. But for a general guide to good football hydration4,5, aim for:
- 400-600 ml of water, 2-3 hours before the match
- 150-300 ml of water, 10-20 minutes before kick off
- 200ml every 10-20 minutes of exercise to maintain hydration from sweat loss
“It’s really important leading up to the match that you are having regular sips of water so that you’re hydrated before exercise, starting from the moment you wake up,” shares Emily, knowing the struggles of keeping up with fluids when you’re darting around the field.
“I recommend a water bottle or sports drink available on the side of the pitch,” she says. “For example, if someone's injured and play is paused, you can nip over and quickly have a drink. When we play sport, we have to think ahead with hydration strategies. And then at half time as well, try to get some of those fluids replenished too.” But remember, don’t go past your limit and end up feeling bloated: “We want enough water to make you feel better, but not so much that you’re uncomfortable and can't do the exercise,” she adds.
After the match, drink as much as you feel you need - listen to your body to ensure you don't over hydrate. If you've been sweating a lot, you may also want to consider an electrolyte supplement to go alongside all that fluid.
