treadmill compliance and oxygen uptake

[Guy Leahy]

I'm a graduate student in biomechanics at Western Washington University
in Bellingham. I'm beginning my thesis topic, which is comparing the
oxygen consumption of subjects when they run on a "hard" versus a "soft"
treadmill. I've scoured the literature for related work, but have only
been able to find two similar articles to date. I would be very
interested to know if anyone out there is either working on similar
research, or has a paper in press tht relates to this topic. If the
latter, I'd like to know which journal the piece will appear in.
Thanks!
