Summary: Scientist advocate that individuals can exercise too strenuously and thus shorten their life span. Past studies suggest that individuals who walk briskly and cyclists who bike more vigorously for longer periods of time have longer life spans than those who stroll or cycle slowly. These studies, however, did not determine how much exercise was too much. In a study of 1,098 joggers, it was found that those who jogged at a slow pace, between 1 and 2.4 hours per week, had longer life spans. In contrast, those who jogged more often at a much faster pace had decreased life spans equal to that of sedentary non-joggers. The facts, that the population of hardcore joggers was considerably smaller than that of the slow joggers, and that researchers

The U-shaped association between mortality and dose of jogging suggests that there is a point at which too much running begins to have a negative impact on life expectancy. (292)
3. Headline vs Science – Win or Fail
The article in the New York Times, titled “Slow Runners Come Out Ahead,” is correct when summarizing the scientific article, but fails to adequately cite the review. The author states that people who jog generally have longer life spans than sedentary individuals. She also mentions that jogging 1 to 2.4 hours weekly at a slow pace is ideal for expanding one’s life span.
Participants that jogged most often and at the fastest pace, however, had similar mortality rates as sedentary non-joggers. These findings are consistent with those in the original study. The article also warns readers to view the results of this study “cautiously” because of the small size of the strenuous joggers’ group and the lack of data on specific causes of death. This warning puts a damper on any fluff that may have risen. It fails, however, to even mention the title of the journal article it summarizes or source it and the other research articles that are
