Tennis fuel.

Energy needed in tennis is not caffeine energy

Sustaining output, point after point

Tennis isn’t a one-burst sport. It’s repeated high-intensity effort layered over incomplete recovery, often for hours. It sits in a middle ground between endurance and power, where rallies rely heavily on anaerobic energy systems, but matches depend on aerobic recovery between points. The common denominator across both is carbohydrate availability. When it drops, performance drops with it.

Tennis sports nutrition guidance consistently points to electrolyte-enhanced carbohydrate fluid during changeovers. Not just for increased energy and sustained output during play, but also to speed up the absorption of fluid into the body.

What this looks like in real matches

Watch the pros on changeovers and you’ll see them taking a bite of a banana or other snacks and fueling with “pink drinks” aka carbohydrate drinks. Even half a banana delivers roughly 12–15 grams of carbohydrates. This is enough to give them enough energy to perform in the next 2 games. 

At the recreational level, fuel is often ignored completely. Many players rely on water alone and no carbs, then blame their lack of fitness when their pace drops in the second set. In tennis, energy deficits accumulate slowly, but then present subtly in weaker shots, delayed reactions, and lethargic footwork.

A fuel system built for tennis

HydraCourt Performance uses a dual-carbohydrate approach designed around drinkability, absorption, and repeat use on court:

SusCarb™ (highly branched cyclic dextrin)
Studied in athletic contexts and discussed for properties like gastric emptying and gastrointestinal tolerability during sport. We chose this complex carbohydrate to support steady energy delivery without heaviness during long sessions.

Dextrose (glucose)
Provides readily available carbohydrates and supports the sodium–glucose transport pathway that enhances fluid absorption. Simple, functional, and effective when points stack up and recovery windows are short.

Together, the blend provides the carbs of roughly half a banana at matchday dose (2 servings), supporting energy and hydration at the same time. Enough fuel to matter, without overwhelming the gut, and without the sugar crash.

 

Key Fact

SusCarb™ Dextrin (HBCD, Highly Branched Cyclic Dextrin) is a patented carbohydrate engineered for optimal energy release and performance.
