Fuelling During a Football Match 

Football, at every level, is fast, dynamic, and unpredictable. That’s the beautiful game. The action doesn’t let up – you’re constantly sprinting, tackling, jumping, pressing, and making decisions under pressure.  

We’ve looked at day-before loading and match-day hydration. Now it’s time to address the all-important 90 (or often more) minutes.  

What you take on the field directly impacts your running output, your technical execution, and your focus – especially later on, when many games are decided. 

So how do you fuel your best performance? 

Mid-match fuelling: why it matters 

You’re constantly on the move to create space or close it down. You make a burst at full pace to lose your marker. Possession changes hands. You cover the back. You go again. 

These repeated high‑intensity efforts drain your energy reserves fast. Even when you’re fully stocked, your work rate generates a demand for more.  

Ignoring that demand means low energy – your legs get heavy and your reactions slow up. Is your opponent better fuelled? A sub arrives fresh from the bench? You’re in trouble. 

Today’s game: topping up to last 90  

Fuelling and hydration go hand in hand. Alongside fitness and tactics, they’re the main reason the pace of the game has changed so much.  

In 1966, it was just half-time water (and not nearly enough). But sports science has shown that in-play fuelling is essential to avoid fading. You only have to look at the second-half tired legs and wide-open spaces in old match footage for proof. 

Let’s look at how to get it right. 

Carbs for football. How? How many? How often? 

Carbs are your primary fuel. You store them as glycogen. On the pitch, you burn through it and need to replace it. 

High-quality sports drinks and gels provide a quick, easy solution. They’re designed to deliver fast-release energy in a manageable format. 

The goal is to restore your glycogen steadily without overloading your stomach and slowing you up. They certainly tick those boxes. Getting used to them in training ensures it. 

Research shows that players at all levels benefit from 30–60 g of carbs per hour. That’s where you need to be. 

Start your intake midway through the first half, during a break in play. At half-time, really focus on your refuelling and rehydration. In the second period, pick your moments to keep topping up. 

The easy route to game-changing energy 

Your fuel must be convenient to take and comfortable on your gut – so you can get straight back to work. The most effective options: 

• SiS GO Energy Gels – the gels the pros use – provide 22 g of ready-to-go carbs, with no extra water needed.  

• SiS HYDRO Tablets and SiS HYDRO+ sachets support fluid retention and keep you covered for minerals lost in sweat. 

• A Science in Sport Energy Drink takes care of everything – pre-formulated with 60 g of carbs, fluid, and electrolytes.  

They’re not just the best products for football; they’re ideal for any team sport where consistent energy is crucial. 

Hydration: your constant companion 

When dehydration creeps in, you struggle to regulate temperature, your running output drops, and your technical skills suffer.  

Aim for 150–250 ml of fluid every 20 minutes, adjusting intake based on heat and humidity. 

It’s a balancing act. Little and often beats excessive volume. In the modern game, you get plenty of opportunities, so don’t miss out. 

No-sweat nutrition: don’t forget salt 

Cramps or heavy legs in the second half? 

This could be down to carbs, hydration, or electrolytes. Maybe a mix of all three. 

Every player needs to consider the climate and their sweat levels. Excessive sodium loss affects fluid balance and nerve signalling. 

Taking care of your electrolytes alongside your fuel and drinks is just good match-day practice. 

An extra lift: the role of caffeine 

Caffeine’s not for everyone, but it has a lot to offer. 

The right dose, at the right time, can sharpen your focus, improve your reaction speed, and make you feel less tired.  

But it’s vital not to overdo it – don’t risk edginess and stomach issues. 

An SiS GO Energy+ Caffeine Gel, either before kick-off or at half-time, can be a useful boost. 

Going the extra mile: fuelling the long game 

In knock-out competition, extra time (and maybe penalties) are a real prospect. You have to be ready for it. 

You may have played two hours, plus added time. You may have been on the bench for 70 minutes. You’ve got to prepare for anything and everything. 

Fuel early, fuel well, and listen to your body. 

Fuelling for football performance

In-play nutrition is a key performance tool – a controllable that supports every sprint, every touch, and every decision.  

We all love the pace, intensity, and skill of the modern game. But it’s relentlessly demanding. You can only deliver when you maintain your energy supply. 

Own your fuelling and give yourself an edge.
