What is a potential benefit of training at altitude?

Training at altitude offers several physiological benefits, particularly in relation to aerobic capacity and endurance. When athletes train at higher elevations, the lower oxygen levels present in the atmosphere stimulate the body to adapt by increasing red blood cell production, enhancing oxygen delivery to muscles, and improving overall cardiovascular efficiency. This process can lead to an increase in aerobic capacity, making the body more efficient at utilizing oxygen during prolonged physical activity.

Furthermore, these adaptations can translate into improved endurance performance when the athlete competes at lower altitudes, where the oxygen levels are higher. Therefore, the correct choice highlights the beneficial effects of altitude training on an athlete’s performance in terms of enhancing both aerobic capacity and endurance. This improvement can be crucial for athletes in endurance sports, allowing them to sustain higher levels of performance over extended periods.
