It is generally believed consuming sports drinks containing 6–8% carbohydrate and also containing 10–20 mmol·L−1 of sodium during endurance events lasting longer than 60-minutes will benefit performance. During exercise in the heat, fluid consumption is also important for thermoregulation. Therefore, the aim of this review is to investigate the components of a typical sports drink, and determine whether there is any effect on exercise performance or thermoregulation in the heat. The results suggest that carbohydrate ingestion during continuous exercise over 60-minutes in the heat can improve time trial and time to exhaustion performance.
