BMAT考试:能力与技巧练习
A brisk 30-minute walk five days a week is more
effective than any other form of exercise for keeping weight down regardless of
age, a major study has concluded. The effectiveness of‘high impact’walking inkeeping weight down is greater than that from keep-fit activities includingrunning, swimming and working out in the gym. Men who walked briskly for 30minutes five days a week for four weeks had a BMI one unit lower than average;for women the difference was 1.8 units. For those who exercised or participatedin sporting activities over similar periods, however, the results were lessmarked: men’s BMI
was 0.3 units lower and women’s about one unit lower. The explanation for this is likely to be thatcalorie burning is optimised when walking because it is a constant,uninterrupted activity, unlike games such as tennis which are more stop-start.
Which one of the following, if true, would mostweaken the above argument?
A ‘High impact’walking as a form of exercise is typicallypreferred by older people.
B There are ways of playing tennis that make itless stop-start.
C People who play sport often drink beers togetherafterwards.
D Keeping weight down is seldom cited as theprincipal reason why people play sport.
