Science in Sport: endurance nutrition formulated on a scientific basis

Science in Sport, known commercially as SiS, is a British sports nutrition brand that presents itself as specialising in endurance performance. Its activity is built around three specific nutritional needs: energy, hydration and recovery, to which it adds a supplements line. The company states that it combines scientific knowledge and proprietary formulations to develop products aimed at athletes looking to improve their performance.

The company traces its origins to 1992 and states that, since then, it has worked with Olympic athletes, world record holders and world champions in disciplines such as cycling, swimming, heptathlon and athletics. Its research and innovation programme is focused on formulating evidence-based products that, according to its presentation, have a real impact on performance.

The SiS catalogue is organised into categories that respond to different moments and goals in physical exercise:

• Energy: energy gels, energy powders, bars and energy bakes, and energy drinks.
• Hydration: Hydro tablets, Hydro sticks, electrolyte powders and bottles.
• Recovery: recovery powders, shakers and products from the REGO line, including Collagen Shots.
• BETA line: BETA Fuel and BETA Recovery.

The shop also offers specific packs by discipline, including packs for running, cycling and triathlon.

Research applied to performance

The company highlights its own research programme and mentions specific data derived from its studies. These include a formulation with a 1:0.8 maltodextrin-to-fructose ratio, a 17% increase in energy efficiency and improved power output during maximum efforts. It also cites a study on elite male marathon running that, according to the company, improves running economy by 3%.
