【正文】 cline when reach middle age. The largest study of the effects of aging on the heart has found that women’ s longevity may be linked to the fact that their hearts do not lose their pumping power with age. We have found that the power of the male heart falls by 2025 percent between 18 and 70 years of age, said the head of the study, David Goldspink of Livepool John Moores University in the UK. Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, onethird of those cells die and are not replaced in men, said Goldspink. This is part of the ageing process. What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70yearold woman’ s heart could perform almost as well as a 20yearold one’ s. This gender difference might just explain why women live longer than men, said Goldspink. They studied more than 250 healthy men and women between the ages of 18 to 80, focusing on healthy persons to remove the confusing influence of disease. The team has yet to find why aging takes a greater loss on the male heart, said Goldspink. The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles being smaller and weaker as they age. 11.
