Medical researcher: Scientists compared a large group of joggers who habitually stretch before jogging to an equal number of joggers who do not stretch before jogging. ████ ██████ ██ ███████ ████████ ███████ ███ ████ ██████ ██ █████████ ████ █████████ ████ ██████████ ██████ ███████ ████ ███ ████ ██ ███████ █████████
Summarize Argument: Phenomenon-Hypothesis
In a study, joggers who habitually stretch before jogging experienced about the same number of injuries as joggers who didn’t stretch before jogging. The author believes this statistic shows stretching before jogging doesn’t help prevent injuries.
Notable Assumptions
The author assumes that there isn’t another explanation for why joggers who stretch get injuries at the same rate as joggers who don’t stretch. For example, the author’s overlooking the possibility that joggers who stretch start off with a higher chance of injury than joggers who don’t stretch. (Maybe joggers who stretch tend to be older and weaker?)
