Good Morning DTrotter,
Your body does not have that capability of tapping into your adrenal glands. If humans could do this, the Olympics would have records that are 3x of what they are now. The reason we do not tap into this is because our muscles are up to scale in strength as far as the bones are. When you are having an adrenaline rush, your bones are 5x more susceptible to breaking do to the force of the muscle onto the bone.
I hope this helps answer your question.
