A lifetime of active exercise will let you keep the body of a 20-year-old well into your 70s, scientists have found.
The physical decline (衰退) thought to be an unavoidable part of ageing is actually the result of not exercising enough, according to the research, which found that regular cyclists kept the muscles, lungs, and even the immune system (免疫系统) of people years younger. Besides, many serious health problems could be prevented if people became more active, researchers insist.
Janet Lord, a leading researcher, said, “Our findings prove the false belief that ageing automatically makes us weaker. We now have strong evidence that encouraging people to do regular exercise throughout their lives can solve the problem that we are living longer but not healthier.”
She looked at 125 cyclists aged 55 to 79 who had been exercising regularly for 25 years and compared them with 75 ordinary people of a similar age and 55 people aged 20 to 36. On a series of physical measures, the cyclists showed no difference from people much younger in their immune systems and making T cells.
Now Professor Lord aims to discover how much exercise people need to do to stay young. “You needn't work out a lot. It may be intensity (强度) that helps—like going up and down the stairs ten times a day.”
While there is no magic method of staying mentally and physically fit in later life, the benefits of keeping active can never be ignored, whatever your age or state of health.
Hi, Maz and Bobby, I don't know what you're up to this Sunday, but if you're at a loose end, come over to my place. We're going to have a barbecue. Tom |
Hi Tom, Thanks mate, but I'm completely snowed under at the moment. I have to write an essay by Monday afternoon, so I'll be working all weekend. I've got nothing arranged for the following weekend though, so maybe we can meet then? I'll call you later. Bobby |
Dear Tom, Like Bobby, I'm a bit tied up tomorrow. Unfortunately, I have to go to my great uncle's house for a family lunch. He was ill so we thought it might not happen, but it looks as if it's going ahead. I really can't get out of it because it's the old man's 60th birthday and most of the family will probably be there. Maz |
Ok you guys, I'm calling off the barbecue. Judging from the grey sky, it's going to rain all weekend anyway. Maybe you'll have done your various duties by the end of the evening and we can go for a drink instead! If you want to relax, I'll be in The Hart, a pub on King Street. Gloria and I are meeting there at about 8:30, as long as nothing else pops up! Don't forget it closes at 10:30 on Sundays. Ok, time to put my feet up and take it easy! Later, Tom |
