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.

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.
