If increasing your heart rate increases your fitness, does that mean you can get fit from fear?

just wondering



i know the answer is no but i dont know why



If increasing your heart rate increases your fitness, does that mean you can get fit from fear?

Fear cause a rush of adrenalin which causes the heart to race, This adrenalin initiates the %26quot;fight or flight%26quot; syndrome. When you%26#039;re scared, it%26#039;s telling you to either stay and fight or get the heck out of there. Adrenalin is given to heart attack victims who%26#039;s heart has stopped. When you exercise,you secrete endorphins instead which helps you with the pain of exercise so you can keep going and it%26#039;s only the exercise that causes a faster heart rate. Hope this helps

Only if you run a mile due to the fear . When you exercise your heart beats faster to supply oxygen to you working muscles . Fitness relates to your efficiency in supplying those muscles with oxygen and the ability to deal with the by products such as lactic acid . When you are fearfull your heart is responding to catecholamines which are released to help prepare you for maximal physical activity . Its called fight-flight response . This happens over a relatively short time and would not be sufficient for a training effect on the heart .
