GLOSSARY

Mixed-Form Fueling combines liquid, solid or semisolid sources within one fueling plan. The total carbohydrate and fluid from all sources must be counted together.

Liquid, solid and semisolid sources can all contribute carbohydrate, with digestion and tolerance influenced by their composition and the exercise context. A drink may help combine fluid and fuel, while solid food can add variety during longer events. A concentrated gel may need to be coordinated with water according to its formulation and the plan. Combining forms should account for the total intake rather than counting each product in isolation or assuming liquid carbohydrate bypasses digestion and absorption limits.

Sports foods provide nutrients in forms designed for convenient use around exercise. Gels, chews, bars and drinks differ in carbohydrate amount, fluid needs, texture, fat, fiber and additional ingredients. Branding does not establish superiority over ordinary food, and a gel need not contain every nutrient required for recovery. Check the actual serving and label, including caffeine where present. Choose the form that is practical and tolerated in the planned activity rather than assuming that all sports products are interchangeable.

Carbohydrate requirements vary with the intensity, duration and importance of the work. Daily intake relative to body mass describes a different quantity from an intake rate during exercise, which is commonly expressed per hour. A larger daily target does not mean the same amount should be consumed in every session. Match supply to the schedule, starting stores and practical tolerance, and distinguish grams eaten from grams absorbed or oxidized when discussing a fueling plan.
