To evaluate the metabolic and hemodynamic response to the use of Exerstrider (E) walking poles versus 1.4 kg (3.09 lbs) handweights (H) versus walking (C), ten subjects engaged in twelve randomly assigned trails at speeds of 53.6 and 80.4 m/min, and grades of 9 and 5% on a motorized treadmill. Energy cost was obtained by open circuit spirometry, blood pressure by auscultation, and heart rate by telemetry.

The following data were obtained:

Statistical analysis by ANOVA (P<.05) revealed significant differences between the control mode versus both Exerstrider and handweight trials. No significant difference in minute ventilation, oxygen consumption, blood pressure, heart rate, or rating of perceived exertion was evident between E and H trials at matched workloads. Moderate paced walking (53.6 and 80.4 m/min) with either Exerstriders or handweights requires approximately 20% greater calorie expenditure compared to standard walking at all workloads. The use of Exerstrider poles may provide additional support for balance with a small but significant increased metabolic demand similar to the use of handweights at moderate walking speeds.
