Abstract: The purpose of this study was to compare the effects of isotonic and isometric exercise on the physiological variables of oxygen consumption, hemoglobin concentration, systolic blood pressure, diastolic blood pressure, and pulse rate. Conditions of the experiment were base homeostatic level, isotonic exercise level, and isometric exercise level. Under each of these conditions, measures were taken for each of the physiological variables. The basis for comparing the two exercise series was specified as a one-minute duration of exercise with a weight load of approximately ten pounds. Ten members of the graduate class in physical education of the University of North Carolina at Greensboro were randomly selected to be subjects for the experiment. All subjects had normal hemoglobin counts; none of them had donated blood within six weeks prior to the experiment. A one-group method was the basic design of the study. Measures taken on the physiological variables were compared among the three conditions of the experiment. Fisher's "t" test of significance for small, correlated groups was the statistical tool used in this study.
