How does physical activity effect our hormone? - (Nov/08/2014 )

Referring to following statements, I would like to know on why physical activity can alleviate stress, and how does physical activity effect our hormone?

Does anyone have any suggestions?
Thanks in advance for any suggestions

"The hypothalamus, pituitary gland, and adrenal glands make up the HPA axis, which plays a pivotal role in triggering the stress response. By releasing certain chemicals, such as adrenocorticotropic hormone (ACTH) and cortisol, the HPA axis rouses the body for action when it’s faced with a stressor."

"Exercise. Physical activity alleviates stress and reduces your risk of becoming depressed."

This looks suspiciously like homework, so I have moved it...

 

As such, what do you know about hormones and exercise? What hormone releases might be triggered by exercise?

Oxygen is good for burning glucose into energy and release CO2, why do oxidative cause stress to cells?

 

Does anyone have any suggestions?

My honest suggestion is that you google oxidative stress and read some basics in order to be able to build upon that knowledge later.
