Anyone who cycles for sport, trains hard, or just rides long enough to deplete the body's own energy reserves has special requirements when it comes to nutrition. The composition of carbohydrates, fats, proteins and minerals in dedicated sports nutrition is optimised for use before, during or after exercise. Energy drinks provide the athlete with the necessary fluids and also restore depleted electrolytes. Energy bars and gels are carbohydrate power packs that provide the body with plenty of quickly usable and digestible energy. Protein-based products and additional mineral or vitamin supplements help the body recover better after sport.
