How many times does the heart beat per minute during exercise?

Answer 1

50% of your Max Heart Rate = ( example 90 beats per min ) 60% of your Max Heart Rate = ( example 108 beats per min ) 70% of your Max Heart Rate = ( example 126 beats per min ) 80% of your Max Heart Rate = ( example 144 beats per min ) 90% of your Max Heart Rate = ( example 162 beats per min ) 100% of your Max Heart Rate = (example 180 beats per min.) 50% of your max heart rate is considered a light exersise(walking, slowly biking,ect). 75% of your max heart rate is considered a moderate exersise(Jogging,Basketball,ect). Your max heart rate or near your max is considered a heavy, intense activity that makes you huff and puff and your heart is pounding very rapidly (sprinting, track and feild races, ect).

Answer 2

When you have finished exercising, you will notice your breathing and heart rates will still be higher than before you started. There are two reasons for this: During exercise, your muscles need to release energy to help you move. They respire in one of two ways - aerobically or anaerobically. Aerobic respiration involves using oxygen to convert glucose into energy. Anerobic respiration does not need oxygen. Ideally, your muscles would rather carry out aerobic respiration, because it releases more energy relative to anaerobic respiration. Also, anaerobic has the disadvantage of releasing a toxic by-product called lactic acid. This causes muscle fatigue, and cramp. So it is due to these two reasons that explain muscles' tendency to use aerobic. However, if you are exercising vigorously, demand for oxygen may overtake supply. Without enough oxygen, your muscles are left with no choice but to resort to anaerobic respiration, which produces lactic acid. When you finish exercise, your body needs to remove the acid. To do this, it needs oxygen. This is one reason why your heart continues to pump faster after exercise: it has to supply muscle cells with oxygen so that the acid can be broken down and removed from the body. Secondly, the heart beats rapidly to help remove another waste product of respiration - carbon dioxide!

A lot! You should do an expiriment on it!
