Not just another sports drink.

The future of endurance fuel is here to increase your performance like never before.

A new energy mix backed by science to increase endurance performance and decrease GI issues. More carbohydrate absorption than traditional sports drinks. No bonking, with consistent energy levels. Effective amounts of the right ingredients.

Super-high concentrations of carbohydrates

Thanks to advancements in sports fuel science, we have been able to develop a sports mix that increases the amount of carbohydrates that the body can absorb and therefore the muscles can use.

HOW MUCH ENERGY?

A significant amount. Each sachet contains 50 grams of carbohydrates, providing 200 calories of energy. But this doesn’t give the full story. The effectiveness of sports fuel isn’t measured by the size of the packet, it is measured by how much of the fuel contents our bodies can absorb per hour. This is determined by the formulation of the drink mix, specifically the types of carbohydrates and the ratio in which they are included.

Unlike traditional sports drinks, we have incorporated advancements in sports fuel science to increase the amounts of carbohydrates that our bodies can absorb. Scientific research has shown that our bodies can make use of up to 90 grams of carbohydrates per hour. Naturally, our mix supports 100% of this intake amount. It's also worth noting that cutting-edge research has indicated that intakes of over 100 g/h are possible and now being observed. With this in mind, thanks to the formulation of our mix, users can technically take in even higher amounts. Although, don’t try this at home, super-high carbohydrate consumption is generally reserved for highly-trained elite-level athletes. This simply demonstrates the capabilities of our mix.

HOW IS THIS CARBOHYDRATE LEVEL POSSIBLE?

By using multiple carbohydrates of specific types, formulated in an optimal ratio, we can increase the amount of carbohydrate that our bodies can absorb, thereby delivering more carbohydrate to the muscle and thereby increasing performance.

In order for a carbohydrate to be used by the muscle, it must go through an absorption process. This basically involves the moving of this nutrient from the intestine into the bodies’ circulation. To do this, it needs the help of a transporter.

Glucose (incl. Maltodextrin, Dextrose, Galactose, Sucrose*) uses a transporter called SGLT1 and is limited to around 60 grams per hour. Attempting to ingest much more than this will result in the excess carbohydrate not being absorbed and instead accumulating in the intestine – undoubtedly causing GI issues. This is the reason that traditional sports drinks are limited and can also be one of the reasons why they cause discomfort.

Scientific research has found that if at the same time we use a carbohydrate that utilises a different transporter, we can deliver more than 60 g/h of carbohydrate to the muscle. This carbohydrate is Fructose and the transporter it relies on is called GLUT5. This ingestion of a combination of carbohydrates can be referred to as multiple transportable carbohydrate, and research has shown that our bodies can make use of up to 90 grams of carbohydrates per hour. Naturally, our mix supports 100% of this intake amount.

*Sucrose is a little more complicated, as it does also include a proportion of Fructose. It is believed that carbohydrate oxidation from a sucrose drink is similar to glucose and does not reach the high oxidation rates observed with glucose and fructose (or other multiple transportable carbohydrates).

Traditional sports drinks: Limited carbohydrates.

Upsurge: Increases carbohydrate absorption.

The four components of endurance fuelling in a single mix

Thanks to advancements in sports fuel science, we have been able to develop a sports mix that increases the amount of carbohydrates that the body can absorb and therefore the muscles can use.

CARBOHYDRATES

It has been known for some time that carbohydrate ingestion during exercise can increase exercise capacity and improve exercise performance. In the early 1900s, it was discovered that carbohydrate was an important fuel for exercise. Since then we have learned that carbohydrate use during exercise could be influenced by diet and that this could have an effect on exercise tolerance. Later, we learned that muscle glycogen played a significant role during exercise and further that carbohydrate ingestion during exercise improved exercise capacity. More recently there have been a series of major breakthroughs with respect to carbohydrate feeding during exercise, including using multiple transportable carbohydrates.

SODIUM

Within the body, sodium mainly sits within the extracellular fluids (the fluids outside of our cells) and it is going to retain water. So, if we do consume sodium in what we are drinking, we are likely to retain more of that fluid in the blood, rather than in the cells. But we are likely to retain more water overall.

If we don’t have sodium it limits the amount of fluid we can drink without overhydrating. Generally speaking, if our bodies are going to end up overhydrated what is going to happen is that we dilute our blood sodium – the result being low blood sodium. So if we dilute the blood in our sodium what tends to happen is that that that excess water there wants to move away from that area where the sodium is low, so it moves into the body's cells to try and even things out. Therefore, the cells begin to swell up and become overhydrated. This means, the more sodium we have, the more fluid we can consume – so we can keep that body water higher. And over long activities, that discrepancy gets bigger and bigger by the hour.

ELECTROLYTES

These help to provide the electrical energy necessary for many functions within the human body. When exercising, some of these essentials may be lost through sweating. They include:

Magnesium

Contributes to electrolyte balance.

Potassium

Contributes to the normal function of the nervous system.

Sodium Citrate

Acts as a pH regulator.

Calcium

Assists against the risk of low bone mineral density.

HYDRATION

We know that dehydration and overhydration impairs performance. However, hydration also impacts other factors that will influence performance, for example gastrointestinal issues. And this works both ways, because we know that dehydration and overhydration are risk factors for gut issues, but if we have gut issues we are not going to be able to drink and hold it down, so that is a risk factor for dehydration.

In terms of performance, when consuming carbohydrate, it is very important to be taking in a proportionate amount of fluid. The less fluid we take in, the higher the carbohydrate is as a concentration of the fluid – creating a greater risk of developing gastrointestinal issues.

By consuming carbohydrates separately from taking on fluid it can be problematic because we might not be taking on enough fluid, resulting in the carbohydrate not emptying from the gut, thereby likely causing GI issues. This is another benefit of Upsurge combining hydration as part of our formulation. Also, by taking on fluid using our mix; hydrating is faster than by drinking water alone.

It is also worth noting that with more carbohydrates in our body, we are also better hydrated, because carbohydrates hold on to the water.

Lowering the risk of gastrointestinal distress

With a founder who suffers with IBS (Irritable bowel syndrome), creating a high-carbohydrate mix that can be tolerated by all our bodies was a top priority. Ingredients are natural and there are no unnecessary rogue chemicals included, creating a mix that is gut-friendly.

A term used in this field to describe gut issues is ‘Exercise-induced Gastrointestinal Syndrome’ and from that comes the goal of understanding what causes these gut issues.

The primary causal mechanisms are the things that are going on in our bodies that lead to gut problems. The main two are a lack of blood flow to the gut and the body’s normal stress response for the nervous system. If that is amplified more than normal, one of the natural stress responses in the body is to shut down the function of the gut – and so things don’t move through, or move through a lot more slowly, and also don’t digest and absorb as well as they would otherwise.

We need to address these primary causes by doing the basic things like making sure we have carbohydrate whilst exercising and having it frequently. Be adequately hydrated (so not dehydrated, but not overly hydrated), keeping body temperature down through different cooling strategies (whether it is having colder fluids, access to ice, etc).

With regard to carbohydrates, an additional function of carbohydrate is that it is protective to the gut, particularly during an endurance setting. We know it helps minimise injury that is likely to happen during these activities. The carbohydrate is also helping to promote some blood flow to the gut. When we oxidise, it produces blood vessel dilators that are really helpful for the blood flow.

Research has suggested that not taking on sufficient carbohydrates during endurance activities increases the damage to the lining of the gut. Particularly over a longer period of time and especially in hot conditions it can really increase the risk of gut issues. The bacteria, and the products the bacteria creates in your gut, can actually get into our blood stream and cause an immune response.

The objective is to undertake small frequent carbohydrate intake (versus a large serving in one hit) because our gut is already challenged with what we are putting it through – it is slowing down and not working to the best of its abilities. We simply do not want to give it a whole big hit of something for it to try and work through all at once. It is much better to do it gradually.

It is also worth noting that if we are not taking on carbohydrate, say for several hours in a row (particularly in the heat), this is going to start to impact on the integrity of the lining of our gut. Then what we do go on to eat is likely not being absorbed and used properly.

The solution to this is to be regularly and consistently sipping our Upsurge mix. Ensuring the stomach is not emptying of carbohydrates, resulting in the gut lining becoming compromised. Plus, also helping support sufficient blood flow, along with the functioning of the body’s normal stress response for the nervous system – to avoid the function of the gut from beginning to shut down.

It is also important to note that another cause of GI issues can be simply down to us exceeding our individual tolerance of the amount of carbohydrate that we can absorb. Everyone is different in the amount that we can tolerate as everyone can oxidise fuels differently. Although it is worth mentioning that we can in fact train our gut. So, we can start with a lower amount (that we are able to tolerate) and build from there.

Another benefit of exclusively using the Upsurge mix is that we can avoid other types of carbohydrates that are not digested and absorbed properly. These might produce gas and bloating, etc. This can then feed back and cause nausea/vomiting type symptoms and slowing down the gut. These might be carbohydrates that we are fine with on a day-to-day basis, but when we are going through exertional stress, and we are already impairing the gut, it doesn’t digest things as well and it doesn’t absorb things as well either. So, putting a whole heap of carbohydrates that are not absorbed all that easily can simply end up in the latter part of the gut where we are just fomenting it. And this can contribute to symptoms such as bloating, nausea, stomach pain, loose bowels, etc.

With regard to hydration, we already know that hydration impacts gastrointestinal issues and that it is important to be taking in a proportionate amount of fluid. The less fluid we take in, the higher the carbohydrate is as a concentration of the fluid – creating a greater risk of developing gastrointestinal issues. If we do not take on enough fluid, this is likely to result in the carbohydrate not emptying from the gut. This is another benefit of Upsurge combining hydration with our formulation.

Complete single-source or complimentary nutrition

Upsurge includes everything we need to fuel for the entirety of our endurance or ultra-endurance activities. It is a complete and energy-dense fuel source and can be consumed, for the entire duration, exclusively or alongside other food sources.

Often during endurance events our appetites can be lacking and we can struggle to face and consume solid foods. Yet it is imperative that we regularly take on carbohydrates. Therefore, an easy fluid-based option is undoubtedly preferable, meaning we no longer need to try and force down difficult foods.

Also, as we already know, another benefit of exclusively using the Upsurge mix is that we can avoid other troublesome types of carbohydrates – found in solid foods - that are not digested and absorbed properly which can result in GI issues.

Using Upsurge exclusively is also a fast & easy solution. Instead of constantly having the inconvenience of grabbing and trying to consume other food sources, we can enjoy the ease of simply sipping a fluid-based solution on a regular basis. This removes the risk of having periods of no fuelling, as well as avoiding a big hit of fuel that our guts have to work through all at once. Both of which will undoubtedly result in gut and performance issues.

It is worth mentioning that an issue that athletes can have with sports mixes is flavour fatigue. To counter this, we have created a mix with a clean and mild taste, available in various light and tasty flavours.

Whilst Upsurge can be used exclusively, it is also suitable to be used alongside other fuel sources too. Indeed, a mix-and-match strategy can be adopted to achieve our carbohydrate intake goals. However, the carbohydrate intake should be balanced with a fluid intake plan (as well as sodium/electrolytes), and it must be noted that solid foods and other highly concentrated carbohydrate alternatives have been shown to reduce fluid absorption. Using Upsurge exclusively is certainly the simplest strategy.

Consistent energy levels without the bonking

Upsurge is a fast & easy solution where small, regular sips stave off bonking. One of the issues we can have when relying on solid foods and other energy sources is that it not feasible to be constantly taking them out and eating them. What this means is that gaps in consumption of carbohydrates results in inconsistent energy levels – drops and spikes. In more extreme cases of drops we can experience what is known as ‘hitting the wall’ or ‘bonking’, a very unpleasant experience, and one that negatively affects performance.

With other nutritional options we can end up taking on big hits of fuel that our guts have to work through all at once. This is not a good scenario as our gut is already challenged with what we are putting it through – because it is slowing down and not working to the best of its abilities.

Another common challenge is that we often fail to take on carbohydrate during the early stages of an activity, leaving us in a deficit.

Also, as we already know, these gaps in fuel consumption have other repercussions such as increasing damage to the lining of the gut, resulting in GI issues and the likelihood that our bodies will struggle to absorb and use any carbohydrate being consumed.

The same consequences apply to sodium and electrolyte intake, as well as hydration. The overriding outcome of all these problems is a negative effect on the gut and performance.

The objective is to undertake small frequent carbohydrate intake, and by regularly sipping Upsurge we can stay ahead of the curve with consistent energy, sodium, electrolytes and hydration levels.

A caffeine version increases performance

Research has shown that caffeine can significantly improve high-intensity and endurance performance. This includes improvements such as lower times, times to exhaustion being increased and greater distances being able to be travelled.

As well as improved physical performance, it has been shown that caffeine can enhance vigilance during bouts of extended exhaustive exercise, as well as periods of sustained sleep deprivation.

The consumption of caffeine during exercise has also been shown to produce a decreased RPE (Rating of Perceived Exertion).

Upsurge's caffeine version can be used in moderation to compliment the regular mix.
