The Benefits of Electrolytes

We all know and love the flavour and function of AMPEDTM Hydrate when we work out, but how much do you know about the science behind this product? AMPED Hydrate is a carbohydrate-electrolyte sports drink, and is designed to support endurance performance and enhance hydration during physical exercise*.

Electrolytes

When we sweat, we lose water, but in addition we also lose electrolytes. Electrolytes, like sodium and potassium, are electrically charged minerals that travel through the blood and other extracellular fluids (1). These minerals have important roles in many processes within the body and must be replaced during and after exercise to restore the balance (2).

On food labelling it’s common to see a value for ‘salt’, which is a combination of two minerals – sodium and chloride. For every 2.5g of salt, this is equivalent to around 1g of sodium (3).

Sodium is the most highly concentrated electrolyte lost in sweat, and its function in the body is to help balance the level of fluids (1, 2). Sodium is a positively charged ion, and works in contrast with the negatively charged ion potassium. This creates a cell membrane potential, which is essential for normal muscle and nerve function (4).

It’s particularly important that sodium levels are maintained during a workout. If sodium levels are low, the amount of circulating fluids can be reduced, which can result in less blood volume and lowered blood pressure, potentially causing fatigue (5).

Carbohydrates

In addition to electrolytes, it’s also important to restore your body’s energy stores after your workout. There’s increasing research to show that consuming carbohydrates during a workout can improve performance, endurance and recovery (6, 7). Consuming carbohydrates after exercise also has benefits, as your muscles are ready to store glycogen at a much faster rate (8, 9). The type of carbohydrate you’re consuming post-workout also plays an important factor. Complex carbohydrates need to be broken down by the body before they can be absorbed in the small intestine. However, monosaccharides, or simple sugars, like those found in AMPED Hydrate, are delivered to the small intestine for absorption more quickly as they don’t need to be broken down.

As AMPED Hydrate provides you with a combination of carbohydrates and electrolytes, these two components work together to stimulate the uptake of sugar and water in the small intestine to help with rehydration* (10).

 

* Carbohydrate-electrolyte solutions contribute to the maintenance of endurance performance during prolonged endurance exercise and enhance the absorption of water during physical exercise.
