Bench step aerobic (BSA) exercise has been shown to help individuals meet the ACSM recommendations for physical activity through the improvement of cardiovascular fitness, body composition, and aerobic capacity in a wide variety of populations. The purpose of this present investigation was threefold: to (1)determine the acute metabolic and cardiorespiratory responses of simple bench step aerobics at two cadences (128 and 134 beats·min-1 ) and two bench heights (6 and 10 inches), (2) calculate the average vertical ground reaction force (VGRF) and time to peak (TPEAK) at these cadences and bench heights, and (3) attempt to create a regression equation to predict force impact and caloric cost for a given individual based upon physiological height, weight, step cadence, and bench height using the resultant ground reaction forces and metabolic costs. Twelve subjects reported to the exercise physiology lab three times: (1) prescreening and maximum treadmill testing, (2) two of the four conditions, and (3) the remaining two conditions. Forty-eight hours rest was allowed after the maximal treadmill test and at least twenty-four hours rest between each lab visit before subjecting individuals to the various experimental conditions. At least fifteen minutes was allotted between exercise conditions within each lab visit. The effect of stepping cadences and bench heights on the averages of HR, VO2, RER, caloric expenditure (kcal·min-1), VGRF, and TPEAK were determined using four separate 2 x 2 analysis of variance (ANOVA) with repeated measures. There were significant differences between bench height and cadence with all the dependent variables (TPEAK, KCAL, and VGRF). No significant interactions were reported between the independent variables (bench height and cadence) for any variable. A regression analysis using step cadence, bench height, subject height and subject weight to predict force impact and metabolic cost yielded modestly reliable equations. In conclusion, bench step aerobics is an effective low-intensity exercise. Definitive intensity modifications may be made through both the cadence of the music and the height of the participant's bench. However, additional research is necessary to determine each individual's threshold for beneficial training adaptations and increased injury risk.
