This investigation determined the short-term memory effects of glucose and exercise. It was hypothesized that (a) glucose enhances short-term memory and (b) intense exercise diminishes short-term memory. Subjects were middle-aged volunteers who regularly exercise. Two within-subjects variables were (a) glucose vs. no-glucose, and (b) before- vs. after exercise. A between-subjects variable was no-glucose beverage type: aspartame, saccharin, or water. Performance on Subtest IV of the Wechsler Memory Scale was the dependent variable. A glucose by exercise interaction suggested an influence of fitness level. In a second experiment, short-term memory was assessed before, and at 20-min. intervals after exercise. Weight and aerobic dance participation were treated as quasi-independent variables. Results revealed diminished short-term memory after exercise, F(18,3)=9.99, R<.0001. Level of fitness affected short term memory performance. Experimental results on exercise reflect the point at which memory is assessed as well as exercise intensity.
