美国加州大学洛杉矶分校研究人员完成的一项研究显示,久坐会使人体内线粒体的DAN端粒缩短,细胞的生物年龄衰老加速。研究人员对1 481名64~95岁的女性参与者进行了问卷调查后,又在她们的右臂部佩戴计数器,连续7天跟踪她们的运动情况。之后对参与者进行了血液分析检查,重点分析她们线粒体内DAN突变损伤情况,结果发现,那些每天久坐超过10小时,运动时间少于40分钟的参与者端粒较短,细胞的生物年 A study done by researchers at the University of California, Los Angeles, USA, shows that sedentary shortening of mitochondrial DAN telomeres accelerates the biological age of cells. After a questionnaire survey was conducted among 1,481 female participants aged 64 to 95, the researchers placed counters on their right arms and tracked their movements for seven consecutive days. The participants were followed by a blood test that focused on the mitochondrial DNA damage in their mitochondria and found that those who had sedentary for more than 10 hours per day and those who exercised less than 40 minutes had shorter telomeres,
