How does altitude affect an athlete's nutrition needs?

Altitude can significantly affect an athlete's nutrition needs, particularly in terms of caloric and hydration requirements. At high elevations, the body faces challenges such as reduced oxygen availability, which can lead to an increase in metabolic rate. As a result, athletes may require more energy (calories) to fuel their activities and support recovery.

Additionally, the dry air at high altitudes can lead to increased fluid loss through respiration and sweating, often resulting in a greater need for hydration. Therefore, athletes training or competing at altitude typically need to consume more fluids to maintain adequate hydration levels.

Overall, the combination of increased energy expenditure and the need for higher fluid intake makes it essential for athletes at altitude to adjust their nutrition strategies accordingly. This adjustment is vital for enhancing performance and preventing dehydration and fatigue.
