PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author.

Half marathon induced changes in navicular height might occur early in the run.

Nice study - well done and I hope to see more from your group.

Quick comment.

In respect to the navicular height measurements it reminded me of a finding we reported in 2000 in which our control no tape group who jogged 10minutes exhibited a 3mm (SEmean 0.35) drop from baseline and that didn't change much over 20 minutes of jogging (3.4mm (0.6))[1]. I think this raises the possibility that the major part of the change in foot posture occurs very early.
