A study was done in 1998 by Dr.Benjamin Levine to explore the role of altitude training in athletic performance.First he trained athletes at low altitude, then measured their finish times in a 5 kilometer run.Then the athletes were placed into one of the following groups: I, living and training at high altitude; II, living at high altitude and training at low; or III, living and training at low altitude.The athletes were then retested in another low-altitude 5 K race.In this study, what are the control and experimental data? What are the dependent and independent variables? The results are expressed as average change in speed of each group.I: -3.4 sec., II: +13.4 sec., III: -26.7 sec.Graph and interpret the results.Did the results surprise you? Why or why not? Propose some explanations for the lower performance by the live high-train high group.Why wasn't there a live low-train high group?
