SiS GO Energy Isotonic Drink: Boost Hydration | Fuel Performance

Current sports nutrition guidelines recommend that athletes performing moderate to high‑intensity exercise lasting 1‑2 hours (such as football, rugby or netball) consume 60 g of carbohydrates per hour during exercise to optimise performance. However, most players fail to meet these targets. A key reason is fuelling preference, players commonly rely on carbohydrate‑containing fluids that also support hydration. This creates a gap: fluid‑based fuelling is the preference, but traditional sports drinks typically don’t provide enough carbohydrate, meaning players often undershoot their fueling needs.

SiS’s GO Energy Isotonic Sports Drink addresses this gap. Standard sports drinks typically contain around 30 g of carbohydrates per 500 ml; GO Energy delivers twice that amount – 60 g per 500 ml. This enables more efficient fuelling, less fluid in the stomach and a reduced risk of bloating or discomfort, as players meet the guidelines with one drink per hour instead of two. With its concentrated, easily digested and rapidly utilised isotonic formulation, GO Energy is a smarter, more practical, science‑led solution to help you stay energised and perform at your peak.

The Power of Carbohydrates

Team sports place unique demands on players, requiring explosive actions with minimal recovery time while also demanding quick decisions under pressure. Sustaining both the physical and mental aspects of play relies heavily on carbohydrates, which are stored as glycogen in the muscles and liver, serving as the body’s primary energy source.

When glycogen stores run low, fatigue sets in, limiting both physical and technical performance. Research shows significant reductions in glycogen can occur within just 1‑2 hours of play. To stop this from happening, athletes should start matches with full glycogen stores by strategically tailoring their total daily and meal‑by‑meal carbohydrate intake to match training or competitive demands.

In high‑intensity sports such as football, rugby or netball, consuming carbohydrates during play is recommended to prevent physical and technical decline by providing an additional substrate for energy production. This will help sustain carbohydrate availability, stabilise plasma glucose and supply a continuous fuel stream to the working muscles.

In short, maintaining carbohydrate availability during play will help keep players performing at their best for longer.

The Importance of Hydration Status

Hydration is essential for sustaining performance. During match play, players can lose significant amounts of water and electrolytes, particularly sodium, through sweat. If these losses are not properly replaced, the athlete risks entering a state of hypohydration (low body water level). Current sports nutrition guidelines advise drinking enough fluid to limit body mass loss to less than 2%, as greater dehydration is associated with declines in endurance, strength and technical skill.

Replacing both fluids and electrolytes, especially sodium, during high‑intensity exercise offers multiple benefits: restoring sodium balance, improving fluid absorption and promoting fluid retention. This helps keep the body cool and supports physical and mental functionality during games.

How Does GO Energy Help Elite Footballers?

Football provides a clear example of where nutrition can make the difference between winning and losing. Matches are often decided in the final minutes, precisely when players are most vulnerable to fatigue and performance decline. As mentioned, this drop‑off is strongly linked to the depletion of muscle glycogen, the body’s key energy store.

To offset this, consensus sports‑nutrition guidelines (for instance from UEFA) recommend that players consume up to 60 g of carbohydrates per hour during a match. Yet meeting this target is challenging and often easier said than done. Pre‑match nerves, reduced appetite and limited chances to eat or drink during play make it difficult for footballers to fuel effectively when they need it most. Research shows that even players in the English Premier League fall short of the recommended intake, consuming an average of just 17 g/hour.

GO Energy offers a solution and helps close this gap. Each 500 ml bottle provides 60 g of single‑source carbohydrate and 350 mg of sodium. A simple, practical strategy is to sip one‑third of a bottle roughly every 20 minutes, delivering 20 g of carbohydrate per serving.

Fuelling guide:

• During warm‑up: sip 1/3 of a bottle to top up carbohydrate availability before kick‑off.
• In the first half: consume a further 1/3 during natural pauses.
• At half‑time: finish the remainder to restore energy and hydration ahead of the second half.
• Late‑game: have an extra bottle available to sip during breaks in play in the second half, when fatigue and glycogen depletion are most likely to affect performance.

Beyond match play, GO Energy can also be integrated into the wider match‑day routine. For example, consuming it the day before a match supports carbohydrate intake and glycogen loading; drinking it immediately post‑match accelerates recovery by stimulating glycogen resynthesis and rehydration.

While football is a prime example, the same nutritional principles apply across a wide range of team sports, such as rugby, netball and hockey, where high‑intensity bursts of activity are sustained over long periods and demand both technical and tactical skill.

Sustain energy levels, sharpen technical aspects and delay the onset of fatigue with GO Energy.
