Does running increase or decrease oxidative stress

Oxidative stress is something that normally occurs in all runners. But we know free radicals and the consequences of an imbalance of oxidative stressors can delay tissue healing. Anytime you have an overtraining injury and you are trying to get back to running, you have to make sure you are healing as quickly as possible. The big question is whether or not exercise, such as running, has a positive or negative affect on oxidative stress. This video by Dr. Christopher Segler talks about whether running increases or decreases oxidative stress.
