The purpose of this research was to compare average heart rate, net oxygen cost, and total caloric expenditure of walking with and without ski poles designed for use while walking at speeds of 3 mph and 4 mph. Ten female volunteers participated in a total of five testing sessions. The purpose of the first session was to familiarize the subjects with the testing procedure. In the remaining four sessions the subjects were required to walk for 30 minutes on the treadmill at the randomly assigned treatment (3 mph no poles, 3 mph poles, 4 mph no poles, and 4 mph poles). The results of three separate 2 (speed) x 2 (poles) repeated measure analyses of variance indicated significant increases for speeds (3 mph was lower than 4 mph) and for poles (no poles was lower than poles) on three dependent variables, average heart rate, net oxygen cost, and total caloric expenditure. It was concluded that an increase in physiological demands could be attained by increasing the speed of walking or by adding an upper body resistance while walking,such as walking with the poles.
