What effect does training at altitude have on free radicals?

Training at altitude increases the production of free radicals due to the low oxygen availability that athletes experience. When exercising in a hypoxic environment, the body relies on increased metabolism and energy production processes that can lead to elevated oxidative stress. This heightened oxidative stress results from the body’s adaptations to the reduced oxygen levels, causing an increase in reactive oxygen species (ROS) as a byproduct of metabolism.

Moreover, while moderate levels of free radicals can support signaling pathways for adaptations in endurance and performance, excessive production can lead to oxidative damage to cells. Therefore, understanding the balance of free radicals is crucial for optimizing training and recovery strategies at altitude.
