【题干】What Happens When You Stop Exercising

Have you ever wondered what would happen if you stopped exercising?A new
study on twins was published in the journal Medicine & Science.The results of the
study are dramatic.
In the study,researchers looked at 10 pairs of twin men.Each set of twins was in
their mid-30s.Each had been brought up in the same family.Since they were
identical,they shared the same DNA.They had maintained the same level of physical
activity for most of their lives.But there was one difference.One twins of each set had
cut on exercising in the past few years due to work or family resure.On average,the
less active twin exercised less than twice a week.,while the active twin exercised at
least twice a week.The research team put each twin through a set of medical tests to
study their overall health.
The results showed big diffferences.While the more active twins had lower body
fat percentage,better endurance level,and normal sensitivity,the inactive twins had
about seven more pounds of body fat ,worse endurance,and signs of disease.Not
only were their bodies different:their brains were different as well.The active twins
had more gray matter (the information processing part of the brain).particularly in
areas that control balance.
The conclusion of the study is clear.Quitting your fitness routine can bring
negative effects to your body and your brain as well.Considering the less active twins
in the study had become couch potatoes(沉溺于看电视的人） only recently,these
changes can sneak up on you a lot sooner than you’d think.So keep exercising.I is
beneficial to your overall health!
