Working out at high altitude results in several physiological effects due to lower oxygen availability. This environment prompts the body to adapt by increasing the production of red blood cells to enhance oxygen transport. Consequently, athletes may experience shortness of breath, fatigue, and a reduced exercise capacity initially. However, prolonged exposure can improve endurance and performance upon returning to lower altitudes. Additionally, training in such conditions can enhance metabolic efficiency and improve overall fitness, making it a valuable experience for competitive athletes.
