If being scared makes your heart beat faster, could watching a scary movie marathon be considered a “workout”?
No,it couldn’t be looked at that way. well first of all it’s going to take alot of time to explain this physiologic change but i’ll try to explain it as best as i can. Your increased heart rate during a scary movie, or in medical term they call “fight or flight” is directly related to your nervous system(sympathetic response) basically what you do is: you just increase your heart rate and to some value your cardiac output(the blood that is being pumped to your systemic circulation) but in a workout you increase both the heart rate and cardiac output to a great value and at the same time you decrease the resistance on your vessles(arteries and veins) deliverying more blood and oxygen to your tissues and opening up more arteriols(very small arteries) and consequently burning more calories that we simply call it excerzise.
