Hello,

My name is Krissy Falk, and I am a graduate student in the Locomotion Laboratory
at CU, as well as a trail runner. I am currently looking for subjects who would
like to participate in a study on stride frequency in uphill and downhill
running and its effect on biomechanics and metabolic cost. Participation is
completely voluntary. In order to participate, you must be 18-35 years old,
injury-free, have had no previous heart trouble (There is a short questionnaire
related to cardiac health and injury, which I can do over the phone or by
e-mail) and run at least 30 miles a week, preferably hill running.

The study consists of three or four sessions: an orientation(<1 hour), one
session on the level, and one at three degrees (5.2%) uphill, and possibly one
at three degrees (5.2%) downhill, each of which will take less than 2 hours,
probably closer to 1.5. Ideally, I would like to have subjects do all four
sessions, but due to the time commitment, I would understand if it were only
possible to do the first three. Sessions would be scheduled at your convenience.

If you participate, I will be able to tell you if the stride frequency you
choose naturally is actually the most metabolically efficient stride frequency
for you, on the level, and for however many slopes you choose to do.
Additionally, I will be able to tell you if, should your preferred stride
frequency differ from your metabolically optimal one, you should quicken or slow
down your stride frequency to become more efficient. Orientations will start
later this week.

If you are interested in participating in this study, please call me at (303)
492-0926 or e-mail me anytime at Kristine.Falk@... and we can get
through the questionnaire and schedule a time for orientation. Feel free to pass
this e-mail on to anyone else who might be interested. Thanks much and enjoy the
trails!
