Ultra Study and Research

Aloha Athletes,

I thought some of you might be interested in this so I am posting for all of you to check out. 

Hello!  To help keep you abreast of research related to ultramarathon running, I call your attention to some recent publications from our group which I’ve listed below.  Links to the abstracts (when available) are provided, or can be found at the research page of the Western States Endurance Run (www.wser.org/research) where the entire list of WSER-related scientific publications can also be found. 

 We are most appreciative of the many of you who have participated in these various studies!

 If you would like to receive the full paper for any of these publications, please let me know and I will be happy to send to you.

 And….if you have not already enrolled in the ULTRA Study, please consider doing so.  A summary of the study can be found at:  http://www.run100s.com/ULTRAstudy.htm

The initial survey is at:  http://bit.ly/ULTRAStudy

Many thanks to the over 1300 ultramarathon runners who have enrolled! 

 Health and Happiness!

Thank you for this information Dr. Hoffman, I look forward to reading these papers. I wonder if your study is limited to just runners or if you take multisport athletes as well?
