Exercise can affect your DNA instantly;Maybe this will motivate you to work out. ? New research supports the idea that you don‘t need to spend hours at the gym everyday for your body to start feeling the positive effects of exercise. ? In fact, a single session on a stationary（固定的） bike can affect your very DNA. ? Okay, so your actual genetic code won‘t morph into that of Conan the Barbarian. （野蛮人柯南——movie） ? But exercise sets signals in motion almost instantly that determine which genes get turned on and off. ? These what-are-called epigenetic changes signal to the muscles to, well, tone up. ?;The study is in the journal Cell Metabolism. （《细胞代谢》） ? Researchers recruited 14 men and women in their mid-20s who didn‘t usually exercise. ? After a short but intense spin on a bike, samples of their muscle tissue showed temporary, but big, changes in several types of epigenetic signals. ;Further tests showed that some of the same effects could be achieved with a jolt of caffeine. ? Alas, black coffee can‘t provide all the benefits of your morning workout. ? But if you get to the nearest coffee shop by running, you‘re definitely starting out on the right foot. ;主播：毛毛戴 海外记者：陈丹忆 古丽加依娜儿 特约记者：胡中玉 鸿迪孜 嘉宾点评：高雅静 陈子莹 再次鸣谢：CCTV NKTV 百度浏览器 谷歌浏览器 优酷视频网 八宿大饼鸡蛋 …………….
