Columnist: A recent research report suggests that by exercising vigorously, one significantly lowers one’s chances of developing certain cardio-respiratory illnesses. But exercise has this effect, the report concludes, only if the exercise is vigorous. Thus, one should not heed older studies purporting to show that nonstrenuous walking yields the same benefits.

Summarize Argument

The columnist concludes that older studies claiming that nonstrenuous walking lowers one’s chances of developing cardio-respiratory illness should be ignored. As evidence, she cites a recent research report which found that only vigorous exercise has this result.

Identify and Describe Flaw

The columnist implicitly assumes that because the recent research report is newer, it must be more accurate than the older studies. However, she never actually provides any evidence for why the recent research is correct and the older studies are wrong.

fails to consider the possibility that the risk of developing certain cardio-respiratory illnesses can be reduced by means other than exercise

The columnist doesn’t fail to consider this possibility. She probably knows that other factors like diet or smoking affect one’s risk of cardio-respiratory illness, but she’s only discussing the effect of strenuous versus nonstrenuous exercise.

fails to consider that those who exercise vigorously are at increased risk of physical injury caused by exercise

The columnist is only arguing that vigorous exercise reduces one’s risk of cardio-respiratory illness. Whether it also increases one’s risk of physical injury is irrelevant.

overlooks the possibility that vigorous exercise may prevent life-endangering diseases that have little to do with the cardio-respiratory system

The columnist’s argument only addresses the effect of vigorous exercise on one’s risk of cardio-respiratory illnesses. Whether vigorous exercise also prevents other diseases is irrelevant.

fails to consider the possibility that those who engage in vigorous physical exercise are more likely than others to perceive themselves as healthy

The columnist is discussing the actual effect of vigorous exercise on one’s risk of cardio-respiratory illness. Whether people who exercise vigorously perceive themselves to be healthy has nothing to do with their actual health.

fails to show that a certain conclusion of the recent report is better justified than an opposing conclusion reached in older studies

The columnist assumes that the recent report is correct and the older studies are wrong, but she fails to provide any evidence for this. She doesn’t give any reason to believe that the conclusion of the recent report is better justified.
