I was just reading about the adrenal glands, which are the areas in our kidneys that produce adrenaline and cortisol, and I have found claims of people performing extraordinary feats of strength do to the presence of adrenaline. Adrenaline increases strength and focus in the body and it's release typically comes to us when we are in an emergency. One example of this is in a video I came across (http://www.youtube.com/watch?v=XbjJBZIONUc) in which this guy rolls a helicopter of his friend who is stuck underneath. As you can see when you watch the video, it makes sense that the release of adrenaline can be very important to us. For instance, it allows us to make quick and focused decisions when we are under a lot of stress.
Although adrenaline clearly makes people stronger, i'm still not convinced that it will increase strength do the degree claimed by the news. I was also wondering how much strength is increased when adrenaline hits the body. Is it like 110% of what a person can normally lift? And does the environment play the most important factor in the amount of adrenaline you receive? For instance, it would seem to me someone who is in the middle of an intense basketball game wouldn't get as much as someone who is trapped under a car. Share your thoughts below, I think this is an important phenomenon.
