Abstract

RODGERS, C. D., J. L. VANHEEST, and C. L. SCHACHTER. Energy expenditure during submaximal walking with Exerstriders. Med. Sci. Sports Exerc., Vol. 27, No. 4, pp. 607–611, 1995. This study was designed to determine whether Exerstriding, a modified form of walking using walking sticks (Exerstriders), resulted in an augmented cardiorespiratory response and a greater energy expenditure than when walking without Exerstriders. Female subjects (23.6 ± 4.0 yr; 58.5 ± 5.5 kg) completed two randomly assigned trials of treadmill walking (6.7 km·h-1; 0% grade; 30 min.) with (Exerstrider ± (E)) and without Exerstriders (Control (C)). Mean oxygen consumption (E = 20.5 ± 1.2 ml·min-1·kg-1; C = 18.3 ± 2.5 ml·min-1·kg-1), heart rate (E = 132.5 ± 19.2 beats·min-1; C = 121.5 ± 21.2 beats·min-1) and respiratory exchange ratio (E = .82 ± .03; C = .78 ± .04) were significantly greater (P ≥ 0.05) while walking with Exerstriders. Total caloric expenditure was also significantly greater during the Exerstrider condition (E = 173.7 ± 20.9 kcal; C = 140.7 ± 27.2 kcal.). In contrast, the rating of perceived exertion did not differ significantly between the two conditions. These data suggest that Exerstriding provides a means to increase caloric expenditure during submaximal walking, a factor that may be of critical importance in enhancing health benefits–such as improved body composition and aerobic capacity–typically associated with walking programs.
