Briefly describe a specific question, or set of related questions, about a health care test or treatment that this program should consider.
Does creatine monohydrate affect joint range of movement?


Describe why this topic is important.
A lot of people supplement with creatine. It is also found in meat. If it affected joint range of motion, it could potentially hinder athletic performance.

So far, a singular study found a decrease in range of motion.

However, the study only covered the shoulder, elbow, hip, and ankle. A longer term study may have been more useful, also. The study mentions that reduction may have been caused by water retention. Studies have shown that the water retention, caused by creatine, disissipates after 6-12 weeks. So, it may be a good idea to do a 6-12 week study.

Potential Impact

How will an answer to your research question be used or help inform decisions for you or your group?
The results will establish whether creatine hinders athletic performance, through a reduction in joint range of movement.
