1. The Academy of Sports Medicine Physicians is interested in determining whether a new

training regimen will long-distance runners improve their performance in marathons.
This organization comes to you for some advice on how to design an experiment to test
whether this new regimen is more effective than the standard regimen. You have access to a
sample of long- distance runners on the track teams at ten different universities. You hope
to conduct the experiment over the course of two years because the regimen takes a long
time to learn and because you want to include new runners in the sample as they join the
track team. You also believe that the effect of the regimen on performance may differ for
men and women.
Your challenge is to design an experiment that uses a randomized approach to measure the
effect of the new regimen on performance.
Remember, your design should take into account your concerns about different effects for
men and women and should be set up so that new subjects can be properly included in the
experiment. Create an experiment that will address these concerns.
Pay particular attention to the factors, explanatory and response variables, any blocks or
matching characteristics, and the treatment conditions used in the experiment.
