The first step in exercising for most people is determining whether or not they should. This is particularly true with anyone over thirty-five, especially if they have been heavy smokers. (33) Likewise, young adults who have been very inactive should process slowly and with caution. A physical evaluation from a physician is recommended, preferably one that includes an exercise-stress test. While a person is exercising, a stress test detects cardiovascular (心血管的) problems that might not show up when the body is at rest. This is done by monitoring blood pressure, pulse rate, oxygen consumption, and the hearts electrical activity while exercising.
Whatever exercise program is selected, (34) it is important to start with warm-up periods. These should include stretching exercises, jumping jacks, or active walking. The idea is to increase heart rate and circulation slowly without placing a sudden strain on the heart or the muscles that are starting to work. The next phase in developing an exercise program is to determine the amount of exercise that is enough to condition the muscles and cardiovascular system without overly straining the body. This involves taking one’s pulse and finding one’s target zone.
(35) This target zone, or safe-training pulse rate, is established by subtracting one’s age from 220 and then taking 60 percent to 80 percent of that total. If you are just starting to exercise, 60 percent is recommended; 80 percent is recommended if you are already in good condition.
Questions:33. What should the inactive young adults do when they decide to do exercise?
34.What does warm-up exercise exclude?
35.What would be the suggested the safe-training pulse rate if you are a beginner and at the age of 45?
选项
A、To determine whether-or-not they should.
B、To process slowly and with caution.
C、To have a muscle check.
D、To increase heart rate.
答案

文中讲话人提到对大多数人来说运动之前应决定是否应当参与,对35岁以上特别是抽烟很凶者来说尤其如此!而一直不怎么运动的年轻人也应当慢慢开始且谨慎待之。故选B)项。
