Five Sets of Sweat: The Tennis Electrolyte Protocol
How Grand Slam champions manage sodium depletion and blood plasma volume during five-hour matches in the Australian summer.
A five-set match at the Australian Open is arguably the most brutal fluid-management challenge in modern athletics. The hard court radiates 50°C heat, and the match duration is entirely unpredictable.
The Five-Hour Furnace
A five-set match at the Australian Open in January is arguably the most brutal fluid-management challenge in modern athletics. The Plexicushion hard court absorbs the relentless Melbourne sun and radiates heat upwards, creating a microclimate on the court that frequently exceeds 50°C (122°F).
Unlike a marathon runner who knows exactly how long they will be running, a tennis player faces a terrifying variable: the match duration is entirely unpredictable. It could be over in 90 minutes, or it could drag on for five hours.
