There was no effect of running time on implicit memory, but faster runners did a little better on the explicit task:<br /><br /><i>"Control group participants averaged slower running times than did marathon group participants. We therefore performed two ANCOVAs, the first with implicit score as the dependent variable, group as the fixed factor, and running time as the covariate. There was no effect of running time on implicit memory... We performed the analogous ANCOVA with the explicit scores. Running time, here, had a significant effect... The effect of group, controlled for running time, was slightly stronger than before, indicating that the difference in running times across groups had been partially masking the negative effects of marathon running on the explicit memory task."</i>The Neurocritichttps://www.blogger.com/profile/08010555869208208621noreply@blogger.comtag:blogger.com,1999:blog-21605329.post-60404612853032844422009-07-30T09:49:06.395-07:002009-07-30T09:49:06.395-07:00Did they control for training, finish time, previo...Did they control for training, finish time, previous marathon experience, etc? Did the research article discuss any differences between participants in the New York City Marathon vs. the Boston Marathon? Since the majority of runners in the Boston Marathon have to hit a certain time in a prior marathon to qualify for the race, I'd imagine they might be different than the folks in the New York City Marathon (open to anyone).<br /><br />Of course, I guess you could argue it either way: 1.)The Boston Marathoners should be less stressed because they have more training or 2.)The Boston Marathoners are more stressed because they are running faster.Kylenoreply@blogger.comtag:blogger.com,1999:blog-21605329.post-43261518568672556882009-07-16T14:11:19.478-07:002009-07-16T14:11:19.478-07:00Mimi - what specific studies are you talking about...Mimi - what specific studies are you talking about?
