The Tennis Demand
A tour-level five-set match can run four hours or more, with stretches of high-intensity rallies broken by 25-second points-in-between and 90-second change-overs. The Australian Open in particular has become known for testing hydration limits - 38°C on Rod Laver Arena is real.
The Change-Over Window
The 90-second change-over is when most fluid intake happens at the pro level. Players typically have one bottle of plain water and one bottle of an electrolyte sports drink - sips at every change-over, with a bigger sip at the longer set-break interval.
What Pros Carry
The exact products vary by sponsorship and player preference. Common patterns include a sports drink with carbohydrate (Gatorade, Powerade, custom-mixed brand drinks) plus electrolyte tablets in water. Some players use higher-sodium formulations on the hottest days.
The Heat Rule Era
The Australian Open's Extreme Heat Policy now includes scheduled extra breaks and roof closures when conditions reach defined thresholds. The acknowledgement that endurance athletes can hit the wall is recent - the 'just tough it out' culture has been replaced by smarter heat management.
Club-Level Tennis
For social and club tennis in Australian summer, the same principles scale. A bigger bottle than you think you need, sip at change-overs, add a sodium-containing product for the days you'll be on court for 2+ hours. Staminade, Endura, or a tablet brand are all sensible picks.

For sessions over an hour in heat, yes. For short club matches in mild weather, water plus a normal day of eating is fine.
What happens to players in extreme heat?
The Australian Open's Extreme Heat Policy includes scheduled breaks and roof closures when conditions reach defined thresholds. Hydration plans become more conservative.
