PRO LINE Energy Bar Fruit Chew

The availability of carbohydrates is a key determinant of performance during prolonged endurance exercise and high-intensity intermittent exercise (alternating periods of effort and short recovery). It is therefore important to replenish carbohydrates during these activities, as they help maintain blood glucose levels during exercise and replenish muscle glycogen stores.

These energy bars are suitable both before and during exercise. Before exercise, athletes should maximize their carbohydrate stores. This is achieved by consuming a carbohydrate-rich diet in the days leading up to a competition or demanding training session (carbohydrate loading) and by eating a carbohydrate-rich meal 1.5 to 4 hours before the event or workout. The energy bars can be eaten as a snack in the days before competition and during or shortly after the pre-event meal.

During exercise lasting 1–2 hours and 2–3 hours, it is recommended to consume 30–60 g and 60–90 g of carbohydrates per hour, respectively, which corresponds to 1 to 2 energy bars. Without carbohydrate intake during prolonged exercise, muscle glycogen stores are typically depleted after approximately 90 minutes.

How many carbohydrates should I consume during exercise?

• Exercise <1 hour: carbohydrate intake during exercise is not necessary.
• Exercise 1–2 hours: 30–60 g of carbohydrates per hour.
• Exercise 2–3 hours: 60–90 g of carbohydrates per hour.
• Exercise >3 hours: 90–120 g of carbohydrates per hour.

The PRO LINE Energy Bar Fruit Chew contains 50 g of carbohydrates in an optimal 1:0.8 glucose-to-fructose ratio. This ratio supports efficient carbohydrate absorption and is ideal when consuming more than 90 g of carbohydrates per hour during exercise lasting longer than 3 hours.

Each bar also contains 200 mg of sodium to help replace salt lost through sweating and support fluid balance.

The formulation is identical to that of the PRO LINE Energy Gel, with the main difference being that the PRO LINE Energy Bar Fruit Chew is a solid carbohydrate source. The bar is divided into two convenient portions and consists of 50% pure fruit pulp, providing a soft, pleasant texture that is easy to chew and consume during exercise.

Athletes aiming for a carbohydrate intake of 120 g per hour can easily achieve this with just two products: one PRO LINE Energy Bar Fruit Chew (50 g) or one PRO LINE Energy Gel (50 g) combined with 500 ml PRO LINE High Carb Drink (70 g).

Who benefits from the PRO LINE Energy Bar Fruit Chew?

Because this bar provides a high amount of carbohydrates, it is ideal for athletes performing (ultra-)endurance exercise lasting 3 hours or longer who aim for carbohydrate intakes of more than 90 g per hour, including: Cyclists, triathletes, duathletes, long-distance runners, trail runners, open-water and long-distance swimmers & other endurance athletes

Why a 1:0.8 carbohydrate ratio?

Ultra-endurance athletes and well-trained endurance athletes often consume large amounts of carbohydrates during exercise lasting longer than 3 hours, sometimes up to 120 g per hour.

During intense exercise, the body can absorb approximately 60 g of glucose per hour from the intestine because the glucose transporter becomes saturated. During prolonged exercise, this can become a limiting factor, as carbohydrate requirements exceed 60 g per hour.

By consuming different carbohydrate types, such as glucose and fructose, simultaneously, total carbohydrate absorption can increase to 90 g per hour or more, because they are absorbed through different intestinal transport pathways.

Studies show that at intakes exceeding 90 g of carbohydrates per hour, ratios closer to an equal amount of glucose and fructose, such as 1:0.8, may be even more effective and are therefore preferred. This is partly because a greater proportion of the ingested carbohydrates can be used as energy without exceeding the capacity of the glucose transporter. In addition, this ratio is associated with a slightly lower risk of gastrointestinal discomfort at very high carbohydrate intakes.

The PRO LINE Energy Bar Fruit Chew contains 50 g of multi-transportable carbohydrates in the optimal 1:0.8 glucose-to-fructose ratio, maximizing the use of different intestinal transport pathways. This makes it ideal for endurance athletes performing prolonged, high-intensity exercise and aiming for carbohydrate intakes of up to 120 g per hour.
