Task: Sentence Composition
Input (English): Given the nature of the study we don’t think that this issue is relevant. The story used only relative risk numbers to quantify the benefit. This is inadequate, as we explain in Reporting the findings: Absolute vs relative risk. Also, the story confused association with causation, i.e., “researchers in the U.K. found that weekend exercise appears to be just as effective at preventing heart disease and cancer as exercise done more frequently.” The title of the paper suggests otherwise: “Association of Weekend Warrior and other Leisure Time Activity Patterns with Risk of All Cause Cardiovascular Disease and Cancer Mortality.” See more on the importance of not overstating observational findings. The story does a good job highlighting some of the potential harms associated with vigorous physical activity: “However, experts caution that it is possible to overdo it”  and “more exercise than two and a half hours a week can actually be unhelpful and even harmful.” An expert in the field not associated with the study provides a bit of common sense to the discussion; “There are risks that come with a weekend warrior exercise schedule, especially for people who aren’t used to being active. “I would be more concerned about what’s happening at the point of exercise—not the long-term benefits,” says Dr. Howard Andrew Selinger, chair of family medicine at Quinnipiac University. The story provides adequate information about the study design, the populations involved and some of the limitations of the study design. However, it left out important limitation: The inactive population studied was 7 years older, had more current smokers, and suffered more from unspecified “long standing illness” than the participants who were active. No evidence of disease mongering here. The story does provide some precautionary words from an independent expert in the field related to the risks associated with strenuous exercise. We would have liked to have seen an expert in the field provide comments on the study, the inherent limitations and on the conclusions drawn. Although the focus of the story was the “weekend warrior,” several comments were included suggesting alternative exercise strategies, including: “This could be something as simple as a brisk walk or other low-impact options for vigorous exercise about 20 minutes a day. “In theory, someone who did one bout of 150 minutes of moderate exercise is a weekend warrior,” says O’Donovan. This study shows that it doesn’t matter how you decide to split up the recommended weekly amount of exercise. You just need to do it.” We think that the ability to exercise is generally available, so this is N/A. The story did not establish what’s novel, unlike what we saw in our review of The Guardian’s story. The story does not appear to rely on a news release.
Output (English): ‘WEEKEND WARRIOR’ WORKOUTS ARE BENEFICIAL AS JUST 20 MINUTES OF EXERCISE A DAY
