A Fixx Nutrition Guide to Fuelling for the NRL Pre-Season
The grind of an NRL pre-season is measured less in kilometres on a GPS tracker and more by the relentless cycle of collision, recovery, and having the strength to do it all again the next day. All that hard work in the weight room and on the field means nothing if your body can’t rebuild from the constant impact.
Your sports nutrition is the tool that makes that recovery possible. This guide is your complete framework for fuelling the unique demands of Rugby League, built on simple science from Fixx Nutrition, an Australian brand trusted by athletes in high-contact sports.
The Demands of NRL Pre-Season Training
The NRL pre-season asks more of your body than almost any other sport. While running is integral, pre-season training routines are about preparing for the brutal reality of a collision sport.
Built for the Hit
In a single game, a player can endure between 20 and 40 high-impact tackles. The physical toll creates more than just normal fatigue. Sports scientists call the result “Impact-Induced Muscle Damage”—a level of soft-tissue trauma that requires a far more aggressive recovery strategy than running alone.
The Fuel-Sapping Wrestle
Then there's the hidden energy cost of the wrestle. Those intense isometric holds in the ruck and tackle create a low-oxygen environment in your muscles, burning through your fuel stores at an incredible rate.
Without the right fuel and recovery plan, this combination of impact and intensity leads directly to fatigue, cramps, and a much higher risk of injury before round one even begins.
The Core Pillars of NRL Fuelling
Energy and Carbohydrates
In a game defined by repeated high-intensity efforts (the tackle, the get-up, the 10m retreat), carbohydrates are your primary fuel source. When your carb stores run low, not only do your legs suffer; your brain does too. A drop in blood glucose leads directly to poor decision-making, which in rugby league, means a missed tackle.
That's why Fuel X Pro uses dextrose which makes it easy to digest (Gel X Pro) is dual carbohydrate for energy release purposes). This allows your body to absorb fuel much faster than a single-source carb, providing sustained energy for both your muscles and your mind, with less risk of gut upset.
Protein for Muscle Recovery
The heavy contact in NRL causes micro-trauma to your muscles. To repair this damage, you need protein, and you need it fast. The key to kickstarting the repair process, known as Muscle Protein Synthesis, is an amino acid called Leucine.
To trigger this process effectively, you need to hit the "Leucine Threshold" with a quality protein source within the 30-60 minute window after training. A clean recovery formula like Protein X is specifically designed to deliver this, ensuring your body has the exact building blocks it needs to recover from the impact and rebuild stronger.
Hydration and Winning the Battle with Cramps
Understanding Salt and Electrolytes
Staying hydrated is about more than just replacing fluid. For big athletes working in the pre-season heat, sweat rates can be massive, often exceeding 2.5 litres per hour. In that sweat, you're losing critical electrolytes like sodium, potassium, and magnesium, which are essential for nerve function and muscle contraction.
Cramping in Contact Sports: Salt, Pickle Juice, or CrampFix?
You've probably heard the old locker-room remedies for cramping: salt tablets or a swig of pickle juice. While the intention is right, the method is flawed. The problem? Time. A rugby league game doesn't pause for 20 minutes while you wait for a tablet to digest.
The modern solution bypasses the stomach entirely. The fastest way to stop a cramp is to target the nervous system, using a powerful taste to activate specific nerve receptors (TRP channels) in your mouth. This sends an immediate signal that acts like a "reset switch" for the over-excited nerve, causing the spasm.
This is the science behind CrampFix. Far from a digestive aid, CrampFix is a neuro-muscular tool that works in seconds, not minutes, which is perfect for a quick break in play or at half-time. Crucially for any player under ASADA testing, CrampFix is Informed Sport accredited, so you can use it with absolute confidence.
Your Winning NRL Pre-Season Fuelling Plan
Putting the science into a simple, repeatable routine is the key to consistency. Here is a practical framework to build your fuelling plan around.
Before You Train
About 90 minutes before training, have a quality meal or snack rich in slow-release carbohydrates. At the same time, start hydrating with Fuel X Pro. This ensures your energy stores are full and you're properly hydrated before the first whistle.
During Training
Once you start, your job is to maintain those energy levels. Keep using Gel X Pro (or two depending on the intensity of the training session) for quick acting energy. For hydration purposes keep sipping on Fuel X Pro throughout the entire session; whether you're on the field or in the gym. This drip-feed of carbs and electrolytes will keep both your muscles and your mind firing.
After the Final Whistle
This is your non-negotiable window for recovery. The work isn't over when the session ends. Be sure to refuel with a serving of Protein X within that 30-60 minute window to kickstart the muscle repair process.
For immediate insurance against post-session cramps, have a CrampFix shot ready in your kit bag.
Your Winning Formula for the NRL Pre-Season
Success in an NRL pre-season is built on more than just gutting it out on the field. It’s about fuelling your body for the unique demands of a collision sport—powering those repeat efforts, efficiently repairing the damage from impact, and having a science-backed solution for cramps that won't let you down.
