Summary
The challenge of energy and fluid replacement is one that has to be met in many sports. Evidence suggests that the fluid loss challenge occurs earlier, and across a broader range of sports, than that of energy loss. It is accepted that scientifically formulated sports drinks can help to meet this dual challenge by replacing fluid and energy stores along with electrolytes, such as sodium, that are excreted when sweating. Low calorie sweeteners can be used to maintain the scientific integrity and taste of sports drinks, optimising the uptake of both fluid and energy. The use of low calorie sweeteners can help to promote hydration during exercise, whilst supporting the maintenance or loss of body weight, and contribute to a reduction in the risk of dental caries.
