ESSAY QUESTION:
The following appeared in a print advertisement for a dietary supplement:
“According to a recent study, professional bodybuilders who used Train & Gain, a new protein supplement, over the course of three months experienced an increase in measured strength of up to 20%. Since Train & Gain is now available without prescription at all major pharmacies, superior results are no longer limited to professional athletes. Try Train & Gain today and you too can boost your strength and achieve professional-level performance in just a few months.”
Discuss how well reasoned you find this argument. Point out flaws in the argument's logic and analyze the argument's underlying assumptions. In addition, evaluate how supporting evidence is used and what evidence might counter the argument's conclusion. You may also discuss what additional evidence could be used to strengthen the argument or what changes would make the argument more logically sound.
YOUR RESPONSE:
The argument presented is flawed for numerous reasons. It fails to consider that the supplement may not be the only reason for increased strength in bodybuilders. In addition, the passage uses vague language, which can lead to different understandings for users of the supplement. In conclusion, the argument that a non-professional athlete will be able to increase his strength by taking the supplement is invalid.
The study presented fails to describe whether the supplement was the only factor that affected increased strength. For example, in addition to the supplement, the professional bodybuilders more than likely followed a workout regimen and strict diet that helped them achieve increased strength. People that are not professional athletes are less likely to follow the same types of strict regimens, and therefore, unlikely to achieve similar results.
Language throughout the argument is vague and raises skepticism as to the results that can be achieved with the protein supplement. The definition of strength is not provided by the study, therefore, it is difficult to assess whether strength actually increased, and to what degree, in users of the product. Adding to the vague nature of the argument, is the fact that the author fails to provide a definition of professional-level performance. Even if the supplement does help increase strength, it will be difficult to compare results of a person who is not an athlete against those of professional bodybuilders.
The argument would be considerably stronger if definitions for both strength and professional-level performance were provided and if the study provided additional detail regarding the workout and dietary regimen followed by the professional bodybuilders.
Because the argument makes several unwarranted assumptions, it fails to make a convincing case that a protein supplement alone will help non-professional athletes increase their strength.
