Interviewer(M)Miriam Nelson(W)
Now, listen to Part One of the interview.
M: This morning on Today’s Health, we are going to pump you up. You know, working out is obviously good for your body, but this week’s Newsweek Magazine reports(1-1)there is new evidence that it can boost your brainpower and fight disease as well.(2-1)Miriam Nelson is an associate professor at the Friedman School of Nutrition at Tufts University. Miriam, nice to see you. How are you doing?
W: Very well. Thanks for having me.
M: So, we are talking about rigorous, aerobic exercise, clearly good for your body. Explain to me in layman’s terms if you can now, about(2-2)this new research that says it can also help your brain grow new nerve cells.
W: That’s right.(1-2)What we’ve known for years is that individuals who are physically active have reduced risk of getting Alzheimer’s disease. We’ve also known that people with mild cognitive impairment also have improved function with exercise. There’s some very new research just coming out, which is very exciting. And what is seen is it has taken 11 individuals, and put them on a about 3 or 4 months’ course of aerobic exercise—4 days a week, an hour. And what they’ve seen through MRI Scan is people are actually growing new nerve cells.
M:(2-3)And more new nerve cells mean what to me is someone in my age group.
W:(2-4)Yeah, my age group, too.
M: OK, our age group too, right.
W: What we are seeing is that the new nerve cells are growing. They’re increasing a web and they’re weaved and connecting. It’s all the interconnections of the nerve cells.(3)When you get those connections, your brain functions better: primarily this is in the executive functioning part of the brain. We are looking at multi-tasking, memory, problem solving, name recognition—lots of things that start to decline as we get older.
M: I am sure a lot of people are watching this right now, Miriam Nelson. Can I make up for lost time? I don’t have a history of exercising throughout my life.(2-5)(4-1)Now in 45-50 years old, if I start exercising now, do I make a difference?
W:(4-2)Well, certainly.(4-3)(5)The data we show right now are exercising in your 40s and 50s. Hopefully we want to start a little bit earlier, but in your 30s, 40s and 50s, it will make a difference for reducing the risk of getting Alzheimer as you get older. And there’s even newer research with children that is also very exciting.
