Today, many athletic teams attempt to improve performance by using oxygen during rest periods of games. Fructose, though still used by some, is much less popular today than in the past. For the most part, data supporting both practices are subjective. However, the demonstration by Weinstein et al1 of the direct utilization of fructose by the muscle of an extremity, and the demonstration by Corkill and Nelson2 of the enhanced utilization of glucose in the presence of fructose, lend credibility to this concept. The purpose of this study was to obtain objective data on the influence of oxygen and fructose.
The three-minute Harvard step-test3 and the endurance step-test were utilized. The latter test correlates well with other measurements of performance, such as oxygen consumption and blood lactate levels. Motivation is not a factor with the three-minute test but does influence the endurance test. The subject stepped
