有些人的心脏每分钟搏动次数从静止状态的60次左右增加到140次。

Some people saw the number of heart beats per minute rise from a resting rate of about 60 to as high as 140.

这是由于心脏为身体供血的效率提高了，在休息时心脏每搏动一次可以泵送更多血液，所以每分钟需要搏动的次数减少。

This is due to the heart getting more efficient at pumping blood around the body, so at rest more blood can be pumped around with each beat, therefore less beats per minute are needed.
