[23] Every morning, Tony Diamond goes to a local park for an hour of fast walking. Then he runs for another hour. He also goes to a gym two or three times a week for muscle training. The retired navy captain won three medals at the 2015 National Senior Games in the road race and the race walk in his age group,85 to 89.
"My current age is 86 years old and my fitness age is 44," he says.  "I think I have such a good number because I did a lot of exercise during my life."
Helen White, a versatile athlete who won a silver medal in pickle ball at the 2013 National Senior Games,
plays basketball and also teaches the sport to senior groups.
"I'm 62 years old and my fitness result showed that I was 32 years," she says. [24] "It really wasn't until I turned 50 that I decided to become much more serious and focused about play, and just make sure it is a daily part of my life."
White and Diamond are among some 5,000 competitors in the National Senior Games, a competition for athletes over 50 that was recently held in Minnesota, who took part in the study on fitness age.
The study, led by Dr. Pamela Peeke of the University of Maryland, found that older athletes' fitness age is
more than 20 years younger than their real age.
"You simply input very straightforward data," said Peeke, explaining how the study was conducted. "We ask you questions: your age, height, weight, how much you work out, your waist size, heart rate, blood pressure, and it goes on. Then you press a button, you find out what your actual fitness age is."
[25] "This kind of testing, an assessment of fitness age, is actually very. valid and it helps us understand the benefits of being fit and healthy," she added.
Peeke, a board member of the organization that runs the National Senior Games, says many of the competitors didn't start training until later in life.
"It doesn't matter how old you are," she said.  "20, 25, 30...who cares, all of us can lower our fitness age by staying right on top of it, taking good care of ourselves, especially physical activity."
Peeke says it is never too early or too late to start reaping the benefits of exercise.
What does Tony Diamond's daily exercise consist of?
【解题思路】四项都是名词性短语，且前三项均描述具体的运动，第四项描述具体比赛。本题考查的内容应该是关于运动的，听录音时应将重点放在四项的关键信息上(jogging，fast walking，running，muscle training，road race，race walk)。
【解析】讲话一开始就说明了托尼 ·戴蒙德每天的锻炼内容：“每天早晨，托尼．戴蒙德都到当地的公园快走一个小时，然后再跑步一个小时。”因此可以得出A项错误，B项为正确答案。原文还说他每星期还去两到三次健身房进行肌肉训练，因此C项错误；D项“参加公路赛跑和竞走比赛”并不属于托尼．戴蒙德每日的运动项目，也应排除。
