• Abstract: The practice of physical exercise promotes numerous changes and adaptations to the body. These may vary according to the type of exercise, as the energy demands are different. These exercises can stimulate the production of reactive oxygen species (ROS), molecules that in excess cause cellular damage and oxidative stress. These can generate a decline in sports performance resulting in systemic fatigue that can lead to interruption of practice. There is evidence that the production of ROS is essential for several fundamental organic functions such as gene transcription, demonstrating that an adequate production of reactive species is beneficial for the organism. In runner athletes, there may be a drop in performance during the race due to the distance covered, as there may be greater wear and tear caused by ROS. Therefore, a bibliographical review was carried out searching for studies related to the topic for discussion, in order to provide a deeper understanding of the subject. Papers from 2015 to 2023 were included, prioritizing more recent studies for better guidance on the topic presented. Therefore, this review aims to explain the production of reactive oxygen species in corridors with the aim of observing the increase and possible damage of these molecules in the sport. Therefore, it was noticed that running exercise provides a greater energy demand resulting in a greater need for oxygen consumption and, consequently, production of ROS, molecules that are harmful to cells and can cause muscle fatigue and interruption of exercise.
