    Regular jogging may dramatically up life expectancy

    Primal Fuel
    Washington: Regular jogging augments the life span of men by 6.2 years and women by 5.6 years, according to a new study.

    Reviewing the evidence of whether jogging is healthy or hazardous, Peter Schnohr said that the study’s most recent analysis (unpublished) shows that between one and two-and-a-half hours of jogging per week at a “slow or average” pace delivers optimum benefits for longevity.

    At that pace its equal to walking, and yes low level activity is good for you. Sounds reasonable. Between 1 and 2.5 hrs/week is actually on the low side of move frequently at a low pace though.

    All participants were asked to answer questions about the amount of time they spent jogging each week, and to rate their own perceptions of pace (defined as slow, average, and fast).

    Not particularly impressive data-collection. Questionnaires, as devout MDA-readers should know, are at the bottom of the scientific barrel

    For the jogging sub study, the mortality of 1,116 male joggers and 762 female joggers was compared to the non-joggers in the main study population.

    So really just a correlation study? Nothing about potential confounding variables and controlling for those. I would assume people who jog are more health-conscious and probably eat better and smoke/drink less then those who don't and maybe also do other forms of exercise.

    “The results of our research allow us to definitively answer the question of whether jogging is good for your health, said Schnohr, who is chief cardiologist of the Copenhagen City Heart Study.”

    No, it really doesn't. This isn't how science works, Mr Schnohr. Perhaps you should have paid more attention during statistics courses. Something about correlation/causation and all that good stuff.

    Really, this study sounds completely worthless as it uses the exact same methodology as the monthly study that shows how bad red meat, eggs and other animal products are for heart-health. Now I'm not saying jogging is bad or anything, just that this study isn't capable of proving or disproving that claim.
