Michael notices that every time he gets what he calls an "adrenalin rush," his heart rate and pulse quicken and he feels a surge of energy. He also notices that lately it takes his body longer than normal to return to feeling calm and normal. What might explain Michael's delay in coming down from his "adrenalin rush"?

A adrenalin rush is the firing of dopamine receptors and adrenal glands. The same things happens when someone takes stimulants. what comes up must come down. This is called a comedown and its when your body doesn't have enough dopamine and or adrenaline. eventually his body will start to produce it again and he will feel back to normal.

hopefully this helped

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.

answer 2 is the right one. jim should measure his snack to make sure he is using the right serving size.
