4.How much physical activity do you get?As a teenager,physical activity is important,not just for your future health but for looking and feeling your best now.How active you are early in life may affect how ableminded you are late in life.That was the finding of a new study of cognitive impairment (认知障碍),or a loss in mental abilities.The study involved more than nine thousand women in the United States over the age of sixtyfive.They answered questions about their level of physical activity as teenagers and at age thirty,fifty and late in life.
Laura Middleton of the Sunnybrook Health Sciences Center in Canada led the study.Laura Middleton said,"People who were physically active on a regular basis had lower risk of cognitive impairments in late life.And it seemed that teenage physical activity was particularly important in terms of the prevention of cognitive impairments."
Laura Middleton noted two longlasting effects that physical activity can have on teenagers.Exercise could help strengthen the blood vessels(血管) that carry blood and oxygen to the brain.Also,physical activity is known to improve the brain's ability to repair itself.Moreover,she noted that doing exercise is good for psychological development.
The study is in the Journal of the American Geriatrics Society.Women who said they were physically active even once a week showed less cognitive impairment as measured by a test.There was not a strong link between the amount of physical activity and the seriousness of impairment.But the link was strongest among those who were active as teenagers.
Laura Middleton says other studies of exercise and cognitive skills have found a stronger link in women than in men.Still,she says,there is no reason to suggest that the finding about teenage physical activity should not apply to men as well.
