Preparing the body for 80 minutes

A hydrated muscle performs more efficiently under stress, and rugby’s collision-heavy nature means significant fluid and sodium loss through sweat. Begin topping up fluids 24-48 hours before kick-off and aim for pale urine every 2-4 hours as a simple, practical check.

“Hydration for rugby isn’t something you fix on game day. Consistent intake across the week is what supports performance, temperature regulation, blood flow and focus when the game gets intense.”
– Harry Wright, Rugby Strength & Conditioning Coach

On game day, drink little and often rather than large volumes in one go. Smaller, regular intakes in the 2–3 hours before kick-off help maintain plasma volume without causing discomfort. A final controlled top-up before warm-up ensures you don’t start on the back foot. The goal is balance, not feeling bloated, but not allowing body mass to drop through dehydration before the first collision.

Electrolytes aren’t optional in high-intensity sport, they’re essential. Sodium maintains fluid balance and supports cardiovascular stability, helping the heart deliver oxygen efficiently while regulating heat. Pre-loading sodium stores before training or matches prevents starting with a deficit, while using electrolytes before, during and after the game replaces what’s lost through sweat. Without adequate sodium, plasma volume drops, fatigue rises faster and output declines.

Hydration also supports cognitive performance. Sodium and potassium act as the body’s electrical system, driving the nerve signals responsible for decision-making and muscle contraction.

Even mild dehydration can impair attention, reaction speed and tactical awareness, particularly late in games when fatigue begins to build. “When sodium levels drop, nerve conduction declines and the perception of effort increases. Even mild dehydration can impact the concentration and decision-making players rely on late in games.” says Harry.

Maintaining hydration throughout the match helps players stay sharp when the margins are tight.

Recovery begins immediately. Replacing fluids after a match helps restore fluid balance, protect joint function and accelerate adaptation to the physical stress of the game. Combining water with sodium sources through specialist hydration products or appropriate nutrition improves retention and prepares the body for the next training session. Consistency here supports recovery, sleep quality and readiness to go again.
