Task: Sentence Composition
Input (English): We don’t think that cost is relevant here. Like the story in Newsweek, which we also reviewed, this story does not provide an adequate sense of the size of the potential benefits, stating: In the study, those who met the physical activity target by exercising through the week had a 35% lower risk of death than the inactive adults, with cardiovascular deaths down 41% and a 21% lower risk of cancer death. Using only relative risk rates such as these doesn’t tell the full story. Read more on why absolute risk rates should also be included in news stories. It also makes the study sound like it was experimental in fashion, conflating association with causation. “People who cram all their exercise into one or two sessions at the weekend benefit nearly as much as those who work out more frequently, researchers say. A study of more than 60,000 adults in England and Scotland found that “weekend warriors” lowered their risk of death by a similar margin to those who spread the same amount of exercise over the whole week.” See more on the importance of not overstating observational findings. Although not explicit the story does provide some information on the potential harms before embarking on a “weekend warrior” status. The lead author of the paper recommended, “… to start with moderate exercise, such as brisk walking, and then to set realistic, incremental goals to boost confidence without running the risk of setbacks due to injury. “A middle aged or older person should do as much as 12 weeks of moderate exercise before introducing vigorous exercise.” The story provides some information about the study design, but is silent on the limitations, and they are significant. For example, 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. Physical activity was only recorded at baseline. Also, more than 90% of the participants were white. No evidence of disease mongering here. The sources don’t appear to have any conflicts of interest, and there was one additional source included beyond the lead researcher. The story discusses the impact of different activity levels on early death risk. The ability to exercise is generally available, so this is N/A. Unlike the Newsweek story, the Guardian does discuss what’s novel: “The novel finding is that it appears the duration, and possibly the intensity, of leisure time physical activity is more important than the frequency,” Ekelund said. The story does not appear to rely on a news release.
Output (English): Weekend workouts can benefit health as much as a week of exercise, say researchers
