What is the Science on Protein Supplements

W2: What is the science on protein supplements?

Forum 2B

Title: What is the science behind protein supplements?

This week, you are learning about protein. Many athletes consume protein supplements. In Forum 2a, you found a particular protein supplement and presented information on it. Now, let’s find out about the science behind these. How safe are these supplements? Are they appropriate for exercise? For this discussion, find one peer-reviewed research article (as you did in Forum 1) and present it.


To find your article, go to the APUS online library or PubMed. You are looking for a research article that is published in a peer-reviewed journal; not an article published in a magazine like Muscle Magazine or on the website BodyBuilding. These are for the general public and are not peer-reviewed. The journal article you select should be a research study related to protein supplements and sports performance. Our research question is: Do protein supplements improve sports performance?

Again, a research article is not a review article but reports the results of a research study. You can tell the difference between a research article and a review article because a review article summarizes several research studies.

If you cannot find a research article in the APUS online library, go to the following website: Pubmed. In the search bar at the top (cursor most likely will be blinking in this box), enter “protein supplement exercise.” More than 1800 articles should be referenced. You can select one from this list. DO NOT SELECT AN ARTICLE ANOTHER STUDENT HAS SELECTED. Once you have decided which article you would like to summarize, get that article from the library. We talked about strategies for finding articles in Forum 1.

In your Forum post:

  • list your selected article,
  • provide the reference for your chosen article
  • describe the study and the results,
  • state what the study concluded,
  • evaluate the article. Do you think the study made appropriate conclusions from its data? Was the study designed correctly to address the hypothesis?
  • Does the study support the hypothesis that protein supplements are safe? If yes, tell us how. If no, again tell us how.

Before you post your initial discussion, submit it in the assignment area so its originality will be checked by Turnitin. Points will be deducted if you do not do this. Before you post your discussion, make sure your originality index (%) is less than 15. If it is greater than 15, rewrite your discussion, submit it again in the assignment area and check the %. Keep doing this until your % is less than 15. Only post your discussion when the % is less than 15.
