homeostasis and sports drinks webwalk
A WebWalk is a set of instructions laced with internet sites relevant to the topic under discussion.
A required link is accompanied by helpful hints that you should read before you open the link. The “Go To:”command tells you to click on a link. Once you have completed the work at that link, return to these instructions for your next link.
You should take notes as you move along the WebWalk.
(Taking notes digitally is good practice, as well as good preparation for your future in higher education institutions.)
The Sports Drink and Homeostasis WebWalk has been carefully constructed to lead you through the development of a concept. Be sure to go to the sites in order and follow all instructions given.

Sport Drinks and Homeostasis WebWalk
- Go To: pespmc1.vub.ac.be/HOMEOSTA.html (Homeostasis: Resistance to Change - Principia Cybernetica Web) for a description of homeostasis. Note the different ways homeostasis can be applied (biologically, socially, etc.).
- If all the water were removed from a human body some 30 kg of assorted salts would remain. Despite the impression given by TV's Start Trek or the movie Red Dwarf where dried people are represented by a tiny
pile of salt crystals, 30 kg is a lot of material -- imagine 66 pounds of salt poured all over the floor. Go To: physioweb.med.uvm.edu/bodyfluids/fluid1.htm (Fluid Compartments in the Body, University of Vermont). The human body is 60% water. This site shows how that 60% is compartmentalized into several major divisions. You will not be expected to remember the divisions, but you will be expected to remember the main idea. - Sports drinks have been the subject of much recent scientific study. Read the article, "Play Harder, Longer" by the University of North Carolina Medical School's Dr. Don Kirkendall as he explains new findings. Go To: 69.94.64.50/poweringmuscles.com/article.php?article_id=62 to access the article.
- As a result of such studies, bodybuilding.com reports on a new sports drink called Accelerade. Accelerade is not being promoted here as a product. Rather, you are to Go To: www.bodybuilding.com/store/end/acc.html and critically look at the description and marketing of this product by Endurox that claims to "speed more energy to working muscles-faster!" To further investigate the claims, look at Accelrade's comparison chart to other sports drinks (Go To: www.bodybuilding.com/store/end/acc1.html).
- Consider the following questions:
a) Have you ever consumed a sports drink? If so, why?
b) Did you think about its effects scientifically?
Writing Assignment:
- Write a one page discussion about the scientific effects of sports drinks on homeostasis. (HINT: What do sports drinks have to do with maintaining homeostasis during exercise? Give details from your personal experience if possible.)
- If you were to test the effectiveness of sports drinks, how might you design an experiment during your exercise activities or sporting practices or events
