Title: Glycemic Index and Sports Performance

This week we are looking at sports driven nutrition.  All exercise need carbohydrate as a fuel.  As you learned from reading the chapter on carbohydrates, there are many types of carbohydrates from simple, like sugar, to complex, like fiber. Another way to look at carbohydrate is the spike in blood glucose after we eat food containing carbohydrate.  The glycemic index and glycemic load are built off this concept. To learn more, go to the following website:

For this discussion, we will discuss the efficacy of the glycemic index for athletes. Find one research article on the glycemic index and exercise or athletic performance. Be sure the article you present, investigated the effect of different glycemic diets on endurance or performance. This discussion is not about glycemic control of blood glucose or the glycemic index and diabetes or obesity.


list your selected article
provide the reference for your chosen article
describe the study and the results
state what the study concludes
evaluate the article. Do you think the study made appropriate conclusions from its data? Was the study designed correctly to address the hypothesis?
Finally, provide your opinion on the matter. Be sure to justify your position.



Title: Evaluating Sports Nutrition Sources

There are many sources of nutrition information for the athlete and/or people who coach athletes.  How good are these websites? Lets look at a few and evaluate.

For this discussion, find a source of nutrition information for an athlete which could be yourself.  I dont care how outrageous the source and its claims are because I want you to evaluate it using the following red flags.

Promises a quick fix.
Dire danger warnings for a single product or regimen.
Makes a claim that is too good to be true.
Simple conclusions from a complex study.
Recommendations are based on one or no research study.
Statements are questioned by reputable scientific organizations.
Lists good and bad foods.
Recommendations are made to help sell a product.
Recommendations are not evidence-based on peer-reviewed research studies.
Recommendations use studies that ignore individual or group differences.

In your paper, discuss the sports nutrition source you found and evaluate it using the red flags.  Be sure to include the source you are critiquing in your discussion post.
